Grey gilled discs (Conchomyces bursiformis)

An eerie grey glow and a smooth, velvety top. A short, eccentric stipe and very white, adnexed, close gills.
About 50mm across. Very attractive young caps.
Growing from moss covered branch in a tall eucalyptus rain forest in a national park.
Also called C bursaeformis. Only two species in this genus. These differ from Crepidotus in having white gills and spores.
Young caps are grey becoming pale fawn later.
