Cortinarius austrovenetus, alternately known as Dermocybe austroveneta and commonly known as the Green Skin-head, is an inedible brightly coloured green gilled fungus
which naturally occurs in south eastern Australia
.
in 1928, this mushroom along with many other members of the group was separated from the huge genus Cortinarius
, and placed in the newer genus Dermocybe
, commonly called Skin-heads, derived from the meaning of their scientific names. However, this genus is often treated as a subgenus of Cortinarius only.
which can be up to 16 centimetres (6 in) across.The pigment has been isolated and described as Austrovenetin. They have yellowy brown; adnate gills underneath the cap.
Like all members of the Cortinariaceae family this mushroom has a thin web-like veil (the cortina) protecting the gills in the early stages of growth. Remnants of this veil may be seen (often quite fleetingly) on the mature stem

Description
The fruiting bodies of Cortinarius austrovenetus are smooth with a convex or flat capPileus (mycology)
The pileus is the technical name for the cap, or cap-like part, of a basidiocarp or ascocarp that supports a spore-bearing surface, the hymenium. The hymenium may consist of lamellae, tubes, or teeth, on the underside of the pileus...
