Amanita lesueurii and A. wadjukiorum (Basidiomycota), two new species from Western Australia, and an expanded description of A. fibrillopes

Abstract

lesueurii and A. wadjukiorum (Basidiomycota), two new species from Western Australia, and an expanded description of A. fibrillopes. Nuytsia 23: 589-606 (2013). Three species of Amanita Pers. are documented from Western Australia. Amanita lesueurii E.M.Davison is described from the mid-west region. It is distinguished by its small to medium fruiting bodies with a white pileus and white universal veil (both of which become vinaceous-buff or grey with age), white gills, short white stipe with a small obconic or turbinate bulb, white partial veil, amyloid, elongate to cylindrical spores, and no clamp connections. Amanita wadjukiorum E.M.Davison is described from the Perth metropolitan area. It has medium to large fruiting bodies with a cream pileus that ages milky coffee to snuff brown, a pale grey or buff universal veil that ages hazel to drab, cream gills, grey to buff stipe with a napiform or fusiform bulb, white to cream to vinaceous-buff partial veil that disappears with age, amyloid, ellipsoid to elongate spores and no clamp connections. Amanita fibrillopes O.K.Mill., which was previously only known from the type locality, is a widespread but misidentified species. It has small to large fruiting bodies with a pale peach to pale salmon pileus that rapidly ages cream, a white universal veil that rapidly ages buff or milky coffee, white gills that age buff, white or pale pink stipe with a spherical or obconic or tapered bulb, white or buff apical partial veil that disappears with age, inamyloid, ellipsoid to elongate spores and no clamp connections. A BLASTn search has shown that there are no exact matches of the nuclear ribosomal internal transcribed spacer (ITS) region of each species with those in GenBank.

Amanita drummondii and A. quenda (Basidiomycota), two new species from Western Australia, and an expanded description of A. walpolei

“…Methodology follows that described in Davison et al (2013). In brief, methodology is largely based on that of Tulloss (2008); colours, including the colour of spores in deposit and other shades of white to cream (designated by letters A-G) are from Royal Botanic Garden, Edinburgh (1969) while codes for other colours are from Kornerup and Wanscher (1978).…”

“…DNA extraction, ITS amplification, cloning and sequence analysis follow the methodology in Davison et al (2013). At least one cloned sequence for each species has been deposited in GenBank; sequence identifiers and voucher information are given under each species in this paper.…”

Amanita wadulawitu (Basidiomycota), a new species from Western Australia, and an expanded description of A. kalamundae

“…Two species from stirps Strobiliformis have been recently described from Western Australia (Davison et al 2013). Amanita wadulawitu differs from A. lesueurii in its larger size, the flesh aging smoke grey rather than pale vinaceous buff, and its cylindric spores (Q = 2.21-2.55 cf.…”

Four new species of Amanita sect. Roanokenses (Basidiomycota) from Western Australia

“…In Australia the genus has been monographed by Reid (1980) and Wood (1997). Additional species and clarifications have been made by Miller (1991;1992), Grgurinovic (1997), Davison (2011), , Davison et al (2013;2015;2017a;2017b;2021) and McGurk et al (2016). Currently about 100 named species have been published, but many more await description.…”
