Echinostelium australiense (Myxomycetes: Echinosteliaceae), a new species of slime mould described from Western Australia
KNIGHT, K.J., STEPHENSON, S.L. AND NOVOZHILOV, Y.K., Nuytsia 34: 179–186 (2023)
A new and unusual species of Echinostelium de Bary appearing on samples of bark collected in Western Australia and placed in moist chamber cultures is described and illustrated. This new species is clearly distinct from all other species of Echinostelium as it differs in a number of morphological and colour characters. The dark colouration of the sporotheca, stalk and spores with distinct patches of closely arranged warts arranged in a loosely circular pattern, and a large bi-coloured petaloid collar are unusual for the genus.
Volvopluteus earlei and Volvariella taylorii: new fungi for Western Australia (Basidiomycota, Agaricales, Pluteaceae)
BOUGHER, N.L. AND BARRETT, M.D., Nuytsia 34: 187–201 (2023)
Re-examination of vouchered specimens of pink-spored, volvate, agaricoid fungi held at the Western Australian Herbarium (PERTH) has revealed the first recorded occurrences in Western Australia of Volvopluteus earlei (Murrill) Vizzini, Contu & Justo and Volvariella taylorii (Berk. & Broome) Singer, and affirmed the regional prevalence of Volvopluteus gloiocephalus (DC.) Vizzini, Contu & Justo. The identities of the two Volvopluteus Vizzini, Contu & Justo taxa were confirmed with molecular data relative to extra-Australian samples validated in previous studies. Volvopluteus earlei had not been previously reported from Australia. Evidently Volvopluteus earlei and Volvariella taylorii are less common in Australia than the larger and more often encountered Common Rosegill, Volvopluteus gloiocephalus.
Marasmius australotrichotus (Marasmiaceae), a new setose species from Australia, and an intriguing range extension for M. paratrichotus
GUARD, F.E., DEARNALEY, J., LEBEL, T., BARRETT, M.D. AND BOUGHER, N.L., Nuytsia 34: 203–219 (2023)
Based on morphological characters and molecular analysis of the nrITS regions, Marasmius australotrichotus F.E.Guard, J.Dearnaley & T.Lebel, the first known Australian species in sect. Sicci, ser. Spinulosi is described. The distribution of M. paratrichotus is extended from the West African island nation of São Tomé and Príncipe (ST&P) to Christmas Island (CI) and northern Western Australia (WA). Classification, distinguishing characters, habitat variability, geographic distribution and possible dispersal mechanisms are discussed.
Revision of the connate bract group allied to Goodenia panduriformis (Goodeniaceae), including recognition of three new species
SHEPHERD, K.A. AND LEPSCHI, B.J., Nuytsia 34: 227–254 (2023)
The taxonomy of several species of Goodenia with connate bracts allied to G. panduriformis (A.Cunn. ex Benth.) K.A.Sheph. was evaluated through morphological assessment of herbarium specimens. Consequently, the circumscriptions of G. connata (F.Muell.) K.A.Sheph., G. discophora (F.Muell.) K.A.Sheph., G. daviesii (F.Muell.) K.A.Sheph. and G. panduriformis are revised and new descriptions provided. Three new species, G. aluta K.A.Sheph. & Lepschi, G. crescentiloba K.A.Sheph. & Lepschi and G. obscurata K.A.Sheph. & Lepschi are also recognised, the latter being listed as a species of conservation concern. Further, a replacement lectotype for Velleia helmsii K.Krause is designated and a key, distribution maps and figures are included.
Four new species of Triodia (Poaceae) from the Pilbara and adjacent bioregions, Western Australia
BARRETT, M.D., DE KOCK, P.-L. AND DILLON, S.J., Nuytsia 34: 261–294 (2023)
The Australian hummock genus Triodia R.Br. is currently undergoing taxonomic revision in light of new collections from surveys of remote Australia and increased resolution provided by molecular methods. This paper describes four new species of Triodia from the Pilbara and adjacent IBRA bioregions: T. avenoides M.D.Barrett, T. degreyensis M.D.Barrett, T. karijini M.D.Barrett & S.J.Dillon, and T. lutiteana M.D.Barrett & P.-L.de Kock. All four species are ‘soft’ spinifexes with elongate glumes and lemma lobes subulate to awned, and are only known from the Pilbara and adjacent Carnarvon and Gascoyne regions of Western Australia. Triodia degreyensis is known from a single range system in the north-eastern Pilbara. The taxon formerly known by the phrase name T. sp. Karijini (S. van Leeuwen 4111) is formally described here as T. karijini, and is restricted to mountains above 900 m altitude in the eastern Hamersley Range. Triodia lutiteana is only known from shale substrates north-west of Tom Price, and may be a polyploid species. The new species T. avenoides is segregated from T. schinzii (Henrard) Lazarides based on morphological and molecular differences and a disjunct distribution on sand sheets and dunes of the Carnarvon basin. The central Australian species T. helmsii (C.E.Hubb.) Lazarides is newly synonymised with T. schinzii, since no clear morphological or genetic differences between the two could be established. An amended description of T. schinzii is provided to accommodate these alterations to the species concept. Diagnostic character combinations for each species are given to allow discrimination from all other Triodia species. Triodia degreyensis, T. karijini and T. lutiteana are known from between one and four localities, and have priority conservation statuses, while T. avenoides and T. schinzii are not considered threatened. With the species described here, a total of 29 species and one hybrid are now known from the Pilbara bioregion and its immediate surrounds.
New combinations of Hibbertia (Dilleniaceae) segregated from H. hibbertioides and H. glomerata
HAMMER, T.A. AND THIELE, K.R., Nuytsia 35: 31–45 (2024)
Infraspecific taxa within the southwest Australian species Hibbertia glomerata Benth. and H. hibbertioides (Steud.) J.R.Wheeler are critically re-evaluated. Morphological evidence is presented to recognise H. glomerata subsp. wandoo J.R.Wheeler and H. hibbertioides var. meridionalis J.R.Wheeler at species rank, as H. wandoo (J.R.Wheeler) T.Hammer & K.R.Thiele and H. meridionalis (J.R.Wheeler) T.Hammer & K.R.Thiele respectively. Hibbertia hibbertioides var. pedunculata J.R.Wheeler is reduced to synonymy under H. hibbertioides. The remaining subspecies in H. glomerata are provisionally retained but are marginally distinct.
Revision of the multi-ovulate species of Thysanotus (Asparagaceae), with three new species
MACFARLANE, T.D. AND FRENCH, C.J., Nuytsia 35: 55–76 (2024)
The group of Thysanotus species having more than two ovules per ovary locule (the multi-ovulate species) is taxonomically revised. The three previously described species, T. brachyantherus Brittan, T. lavanduliflorus Brittan and T. nudicaulis Brittan, are maintained and redescribed, with T. nudicaulis being redefined following removal of two new species previously included in its concept. Three new species are described: T. argillaceus T.Macfarlane & C.J.French, T. ellipsoideus T.Macfarlane & C.J.French and T. prospectus C.J.French & T.Macfarlane. The South Australian records of T. nudicaulis are recognised as belonging to T. ellipsoideus. A key to the group and illustrations of some characters are provided and all species are mapped and illustrated photographically.
Typifications in Malleostemon, Micromyrtus, Scholtzia and Thryptomene (Myrtaceae) and a hybrid designation
WEGE, J.A. AND RYE, B.L., Nuytsia 35: 77–81 (2024)
As part of revisionary work in Myrtaceae tribe Chamelaucieae, lectotypes are selected for Malleostemon decipiens (W.Fitzg.) Trudgen, M. tuberculatus (E.Pritz.) J.W.Green, Micromyrtus imbricata Benth., M. sulphurea W.V.Fitzg., Scholtzia ciliata F.Muell., S. teretifolia Benth., S. uberiflora F.Muell. and Thryptomene kochii E.Pritz., and the type of Micromyrtus erichsenii Hemsl. is clarified. Micromyrtus chrysodema Rye is hypothesised to be a hybrid between M. flaviflora (F.Muell.) J.M.Black and a 2-ovulate, white-flowered species of Micromyrtus Benth.
New taxa and a key for Thryptomene (Myrtaceae: Chamelaucieae: Thryptomeninae)
RYE, B.L., Nuytsia 35: 101–135 (2024)
A description is given for Thryptomene Endl. together with a key to all species and subspecies. Nine new Western Australian taxa are described as T. butleri Rye, T. caduca subsp. incurva Rye, T. conica Rye, T. dampieri subsp. capensis Rye, T. interzonensis Rye, T. jilbadji Rye, T. maritima Rye, T. maritima subsp. freycinetensis Rye and T. pieroniae Rye. Updated descriptions are given for T. caduca Rye & Trudgen, T. dampieri Rye and T. salina Rye & Trudgen and brief descriptions are given for three phrase-named taxa to inform future research. Thryptomene sp. Leinster (B.J. Lepschi & L.A. Craven 4362) is synonymised under T. decussata (W.Fitzg.) J.W.Green. Most of the new taxa are conservation-listed.
Stylidium miscellany IV: novel species, recircumscriptions and range extensions for northern Australia
WEGE, J.A., BRENNAN, K.G., BEAN, A.R., BARRETT, R.L., DILLON, S.J. AND BARRETT, M.D., Nuytsia 35: 141–198 (2024)
This paper advances knowledge of triggerplant diversity in monsoonal and arid Australia. The following 14 species are newly described: Stylidium aliforme Wege & Brennan (N.T.), S. anomalum Wege (W.A.), S. brachyotis Wege & Brennan (N.T.), S. brennanianum Wege, M.D.Barrett & A.R.Bean (W.A., N.T., Qld), S. contrarium Wege (N.T.), S. eludens Wege & A.R.Bean (Qld), S. incognitum Wege (W.A., N.T.), S. modicum M.D.Barrett, R.L.Barrett & Wege (W.A.), S. pezidium Wege, Brennan & S.J.Dillon (W.A., N.T., Qld), S. synaptum Wege, Brennan & A.R.Bean (W.A., N.T., Qld), S. tantillum Wege & Brennan (N.T.), S. torquatum Wege & Brennan (N.T.), S. tremendum Wege, M.D.Barrett & R.L.Barrett (W.A.) and S. youwanjela M.D.Barrett, R.L.Barrett & Wege (W.A.). Stylidium tenerrimum F.Muell. (W.A., N.T.) is recircumscribed and S. evolutum Carlquist (N.T.) reinstated to its original circumscription. Narrower circumscriptions of S. fissilobum F.Muell. (W.A., N.T.) and S. multiscapum O.Schwarz (W.A., N.T.) are presented and a lectotype designated for the latter. Stylidium tenerum Spreng. (N.T., Qld, P.N.G.) is placed into synonymy under S. uliginosum Sw. ex Willd. (south-east Asia), and S. symonii Carlquist (N.T.) synonymised under S. floodii F.Muell. (N.T., Qld). Stylidium elachophyllum A.R.Bean & M.T.Mathieson (Qld) and S. irriguum W.Fitzg. (W.A.) are recorded for the Northern Territory, while S. aquaticum A.R.Bean (N.T.) and S. capillare R.Br. (N.T., Qld) are recorded for Western Australia. A record of S. longibracteatum (W.A.) from Kata Tjuta in the Northern Territory is highlighted as having potentially unreliable locality information. Lectotypes are selected for S. claytonioides W.Fitzg., S. cordifolium W.Fitzg., S. irriguum W.Fitzg., S. rubriscapum W.Fitzg. and S. trichopodum F.Muell. Both S. pseudotenellum O.Schwartz and S. mitrasacmoides F.Muell. are treated as names of uncertain application. The existence of appropriated type fragments in Herbarium Lowrieanum, recently bequeathed to the Western Australian Herbarium, is noted.
Key to the Triggerplants of the Northern Territory (Stylidium: Stylidiaceae)
WEGE, J.A. AND BRENNAN, K.G., Nuytsia 35: 199–216 (2024)
An annotated dichotomous key and photographic guide to Stylidium Sw. ex Willd. in the Northern Territory is provided. Stylidium gemmatum Wege & Brennan is formally described, and S. stenophyllum A.R.Bean placed into synonymy under a broadly circumscribed S. pachyrrhizum F.Muell.
Additions to the Styphelia pendula group (Ericaceae: Epacridoideae: Styphelieae) including updated descriptions for S. erubescens, S. pendula and S. retrorsa
HISLOP, M., Nuytsia 35: 233–262 (2024)
Six new species from the Styphelia pendula group, S. altivallis Hislop, S. innoxia Hislop, S. longiloba Hislop, S. porcata Hislop, S. speciosa Hislop and S. tarinensis Hislop are described and illustrated. Four of these are conservation-listed. Updated descriptions of three, long-established species from the group, S. erubescens F.Muell., S. pendula (R.Br.) Spreng. and S. retrorsa Hislop, Crayn & Puente-Lel. are provided for purposes of comparison. A key to those members of the S. pendula group with strictly pendulous inflorescences is also included.
Clarification of Amanita umbrinella (Agaricales: Amanitaceae: Amanita sect. Amarrendiae) and three new, related agaricoid species from Australia
DAVISON, E.M., GIUSTINIANO, D. AND CATCHESIDE, P.S., Nuytsia 36: 27–59 (2025)
Amanita umbrinella E.-J.Gilbert & Cleland is re-described based on the lectotype and collections from around Australia; Amanita umbrinelloides A.E.Wood is synonymised with it. Additional information is provided for A. muriniflammea Tulloss, A.M.Young & A.E.Wood. Three closely related species are described herein as: Amanita horizontalis E.M.Davison & Giustiniano, Amanita doreta E.M.Davison & Giustiniano, and Amanita cinereoalba E.M.Davison, Giustiniano & P.S.Catches. Amanita horizontalis differs from A. umbrinella in its taller habit, in having a membranous partial veil that is horizontal when young, ellipsoid to elongate spores, and in molecular sequences. It occurs in South Australia, Tasmania, Victoria and Western Australia. Amanita doreta is similar in appearance to A. horizontalis and has similar shaped spores; but it differs in molecular sequences and occurs in Western Australia. Amanita cinereoalba is a grey, small to medium sized species with a descendent, evanescent partial veil, and large, broadly ellipsoid to ellipsoid spores. It differs in molecular sequences and occurs in South Australia. The 28S gene region indicates A. cinereoalba is closely related to the sequestrate species A. grandis (Bougher) Justo and A. oleosa (Bougher & T.Lebel) Justo.
Severing the first head of the Hydra: Drosera actinioides, a new species from the D. paradoxa complex of D. sect. Lasiocephala (Droseraceae)
JUVE, N.O., FLEISCHMANN, A. AND KRUEGER, T., Nuytsia 36: 75–84 (2025)
Drosera actinioides Juve, A.Fleischm. & T.Krueger, a new species of D. sect. Lasiocephala Planch. from the Northern Kimberley bioregion (Western Australia), is described and illustrated. It can be distinguished from all known members of this section by its distinctive floral features comprising highly branched, blackish red styles and metallic orange petals, among other characters. Detailed notes on its ecology, distribution, and conservation status are provided.
Three new species separated from the eastern Australian Haemodorum planifolium (Haemodoraceae)
MACFARLANE, T.D. AND BARRETT, R.L., Nuytsia 36: 123–139 (2025)
The taxonomy of the eastern Australian species Haemodorum planifolium R.Br. is reviewed and it is divided into four species, three of them new. Haemodorum brevistylum T.Macfarlane & R.L.Barrett occurs mainly in the South Coast and Southern Tablelands regions, north to the Central Coast and Central Tablelands of New South Wales. Haemodorum collevatum T.Macfarlane & R.L.Barrett has a limited distribution in the Northern and Central Coast regions from Sydney to Newcastle. Haemodorum celsum R.L.Barrett & T.Macfarlane is a species of the Northern Tablelands region of New South Wales and the Granite Belt in the southern Darling Downs District of Queensland. Haemodorum planifolium is re-described and lectotypified. In the revised sense, H. planifolium occurs in the Central Coast and Central Tablelands regions of New South Wales (i.e. Wollongong to Gosford, inland to Newnes). All species are illustrated and mapped and a key to the Haemodorum species of New South Wales is provided.
An annotated checklist of Haemodoraceae, including new taxa and new combinations
HOPPER, STEPHEN D., SMITH, R.J. AND HICKMAN, E.J., Nuytsia 36: 141–238 (2025)
In order to provide an up-to-date checklist of Haemodoraceae informed by published and forthcoming molecular phylogenetics, we describe the following new taxa and make new combinations as follows: Haemodorum subg. Gemina Hopper & R.J.Sm., H. subg. Antiqua Hopper & R.J.Sm., H. sandifordiae Hopper & E.J.Hickman, H. clarksonii Hopper & E.J.Hickman, H. ghungalorum Hopper, Paradilatris (Hopper ex J.C.Manning) Hopper, Paradilatris viscosa (L.f.) Hopper, Wachendorfia laxa W.F.Barker ex Hopper, Conostylis subg. Appendicula (Geer.) Hopper, C. subg. Divaricata (Hopper) Hopper, C. sect. Terraflora Hopper, C. glabra Hopper, C. magna Hopper, C. bungalbin Hopper, C. aculeata R.Br. subsp. bolghinup Hopper, C. robusta Diels subsp. hickmaniae Hopper, C. dasys (Hopper) Hopper, Anigozanthos decrescens (Hopper) Hopper & R.J.Sm., A. condingupensis Hopper & R.J.Sm., A. knappiorum Hopper, A. yorlining Hopper, A. humilis Lindl. subsp. grandis Hopper, A. viridis subsp. sophrosyne Hopper, and A. viridis Endl. subsp. metallicus Hopper. We also reinstate Haemodoraceae tribe Wachendorfieae, Haemodorum subvirens F.Muell., H. leptostachyum Benth. and H. flaviflorum W.Fitzg., and make adjustments in the circumscription of subgeneric taxa in Conostylis R.Br. and Anigozanthos Labill. Notes on variation in need of further taxonomic research are provided in the checklist. With these changes Haemodoraceae is a family of two subfamilies, four tribes, 16 genera and 132 species as follows: Haemodoraceae subfamily Haemodoroideae (10 genera/51 species) comprising tribe Haemodoreae Dumort. (4/38) and tribe Wachendorfieae Dumort. (6/13), and subfamily Conostylidoideae T.Macfarlane & Hopper (6/81) comprising tribe Conostyleae Benth. (5/69) and tribe Tribonantheae T.Macfarlane & Hopper (1/12). We do not support the recent recognition of Haemodoraceae tribe Anigozantheae Z.H.Feng.
