Nuytsia
The journal of the Western Australian Herbarium

Nuytsia is an open access, peer-reviewed journal that publishes original papers on the systematics, taxonomy and nomenclature of Australian (particularly Western Australian) plants, algae and fungi, especially descriptions of taxa, revisions, identification guides, nomenclatural and taxonomic issues, systematic analyses and classifications, censuses, and information on invasive species.

Nuytsia was founded in 1970 and is named after Nuytsia floribunda (Christmas Tree; Moodjar; Kaanya Tree), an arborescent root hemiparasite endemic to south-west Western Australia that is of cultural significance to Noongar Aborigines. One-fifth of all published native plant names for Western Australia have been formally established in the journal, including over one-quarter of the conservation-listed taxa in the State. Refer to the cumulative index to scientific names published in Nuytsia for details, and to the 50th anniversary edition for a synopsis of the journal’s impact.

Nuytsia moved to a hybrid print/online publication model in 2013 and became an online-only publication in 2024. Papers are published electronically on Florabase by the Western Australian Herbarium and are freely available for download and distribution for bona fide scientific or educational use. The journal is also electronically available via the Biodiversity Heritage Library and DBCA library, and is also archived with the National edeposit database. Written permission to use and/or re-publish images and botanical illustrations must be obtained from the Managing Editor. A hard copy of each volume is no longer produced, and subscriptions no longer taken.

Opinions expressed by authors in articles published in Nuytsia are their own and do not necessarily represent the policies or views of the Department of Biodiversity, Conservation and Attractions.

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.
