Rubinoboletus phaseolisporus (Boletaceae) from Western Australia is a Tylopilus with bean-shaped spores
OSMUNDSON, T.W., BOUGHER, N.L., ROBINSON, R.M. AND HALLING, R.E., Nuytsia 32: 87–97 (2021)
The bolete genus name Rubinoboletus Pilát & Dermek has been misapplied in the past to include taxa belonging to several genera including Tylopilus P.Karst. In this study, we provide morphological and molecular phylogenetic justification for alignment of Rubinoboletus phaseolisporus T.H.Li, R.N.Hilton & Watling in Tylopilus with the North American taxon T. balloui (Peck) Singer. Thus, a new combination, Tylopilus phaseolisporus (T.H.Li, R.N.Hilton & Watling) Osmundson, Bougher, R.Rob. & Halling, is proposed for this brightly-coloured species that is apparently endemic to bushland in south-west Western Australia.
Isotropis petrensis (Fabaceae: Mirbelieae), a new species from arid Western Australia
DAVIS, R.W. AND WEGE, J.A., Nuytsia 32: 99–102 (2021)
Styphelia undulata (Ericaceae: Epacridoideae: Styphelieae), a distinctive, short-range endemic from the Geraldton Sandplains
HISLOP, M., Nuytsia 32: 103–107 (2021)
Tephrosia sabulosa (Fabaceae: Millettieae), a new species from Australia’s sandhill deserts
BUTCHER, R., Nuytsia 32: 109–119 (2021)
The new species described herein has been segregated from the complexes surrounding T. rosea Benth. and T. brachyodon Domin, both of which are extremely challenging taxonomically. Tephrosia sabulosa R.Butcher is distinctive; however, its relationship with the other members of these complexes is not yet known. It occurs in sandhill habitats on the crests and slopes of dunes and has a disjunct distribution in Australia, with all but one collection being made from the Simpson-Strzelecki Dunefields bioregion of the Northern Territory, South Australia and Queensland; nearly 900 km lies between these collections and that made from the Kiwirrkurra Indigenous Protected Area (Gibson Desert bioregion) in Western Australia. The new species is described and differentiated from similar taxa, and images and a distribution map are provided.
A revision of Lasiopetalum (Malvaceae: Byttnerioideae) from the northern sandplains of Western Australia, including two new species
SHEPHERD, K.A. AND WILKINS, C.F., Nuytsia 32: 121–149 (2021)
Taxonomic descriptions are provided for eight species of Lasiopetalum Sm. with a centre of diversity in the Geraldton Sandplains bioregion. Circumscriptions are updated for six species, namely L. angustifolium W.Fitzg., L. drummondii Benth., L. lineare Paust, L. ogilvieanum F.Muell., L. oldfieldii F.Muell., and L. oppositifolium F.Muell. Lectotypes are designated for L. angustifolium, L. ogilvieanum, L. oldfieldii, and L. oppositifolium, while the holotype for L. drummondii is clarified. In addition, two new species from the region are recognised and named here as L. biloculatum K.A.Sheph. & C.F.Wilkins and L. erectifolium K.A.Sheph. & C.F.Wilkins_._ Images and distribution maps are provided for all species.
