The hygrophanous surface is smooth, dry and very striated with a brownish or greyish beige colour. Stem: 7-7.6cm long and 1-2mm thick. The surface is white and smooth with a pubescent coating all over but no striations. It is very fragile and hollow with a swollen base that sits inside the persistent, membranous white volva. Gills: Free to adnexed, greyish beige to pale rust coloured becoming more rust brown with age. They are narrow and ventricose. Spores: (11) 11.5-12.5 (13) x 8.5-10 x 6.5-8 μm. Broadly ellipsoid and smooth with a thick wall and large germ pore. Yellow-brown in water turning red-brown in KOH. Basidia: (17.5) 20-24 x 12-15 μm. Clavate and hyaline in water or alkaline mounts.

The specimens studied by Watling were found under bamboo in Castanopsis and Araucaria woodland and on rotten wood in Castanopsis forests in New Guinea.
