Notes

Spore print dark brown. Caps up to about 20cm diam., smooth, dry, yellow-brown in colour. Stalk robust and in some species with conspicuous hanging ring frequently covered by a deposit of brown spores. Gills when young completely covered by veil until shortly before cap is fully expanded. The genus is common with about a dozen species including both native and exotic species, on substrates such as wood of living trees, buried wood, and wood mulch. At least one native species occurs in both forest and urban habitats.

Agrocybe parasitica
Mushrooms of Agrocybe parasitica typically form in clusters, here fruiting on a cut stump of an exotic tree felled in an urban park.
A large (to 200 mm diam.) and conspicuous mushroom forming in clusters on dead standing trunks, on dead branch stubs of living trees, or on stumps. It is readily recognisable by the large, persistent, hanging, skirt-like ring on the stalk from just below
Immature fruiting bodies of Agrocybe parasitica with thick veil stretched to cover the maturing gills. Veil will soon break at margin and hang down on stalk, covered with brown spores as deposited from the gills prior to veil break
