Dermocybe austroveneta (Family Cortinariaceae)

Green Dermocybe

Distribution:

Widespread in eucalypt forests or woodlands in southern Australia. The distribution shown on the map is based on herbarium records and reliable sightings. It is likely that this species has a wider distribution than that shown on the map. However there has been little work on the distribution of Australian fungi and there are surprisingly few herbarium specimens of even the common species. (ACT, NSW, SA, TAS, VIC, WA).

Features:

The dry, smooth, convex to flattish cap can be yellow-green to olive-green and up to 8 cm in diameter. The gills are dull yellow, yellowish ochre to brownish yellow. The stem can be up to 8 cm long and 1.5 cm in diameter. It is dry, smooth and yellow to yellowish ochre, paler in the upper half. When young there is a cobwebby veil (or cortina) that extends from the stem to the edge of the unexpanded cap. As the cap expands, this veil is broken but may leave wispy traces hanging from the margin of the open cap, and also leave fibrillose remnants on the stem.

It is common to see a number of mushrooms growing near one another.

Spore print: rusty brown. Basidiomycete.

Ecology/Way of Life:

The mushrooms of this mycorrhizal fungus appear on the ground.

Other Comments:

The type specimen was collected in South Australia. This is an endemic species.
