Description
Stropharia rugosoannulata, also known as Wine Cap Stropharia, is a medium-sized to large agaric with a greasy, wine-red to reddish brown cap, robust whitish stem with ring and clay or violet-brown gills. The mushroom grows in small trooping groups, sometimes caespitose, on wood chippings or rotting straw at woodland margins.

Cap convex at first, becoming broadly convex to nearly flat. It is sticky when fresh, but soon becomes glossy and dry. The surface is bald, wine red to reddish brown, and fades to yellowish brown or yellowish. Sometimes, cracks develop in old age. The margin is incurved for some time and bears appendicular velar remnants. The flesh is pallid and medium. Gills attached to the stem (adnate), crowded, at first grey, but becoming violet-brown at maturity. Stem whitish, fibrillose, stout, widening at base, with white mycelial 'rootlets'. The ring is white, pendulous, upper surface fluted and sub-apical. Spore print dark purple-brown to purplish black.

Microscopic Features: Spores are ellipsoidal, smooth, thick-walled, 10-13 x 7.5-9µm, with a germ pore.

Many mushrooms are poisonous and some are lethally poisonous. It can be very difficult to distinguish between an edible and a poisonous mushroom. Because of that, we strongly advise against consuming wild mushrooms, and this site does not contain any information about the edibility or toxicity of mushrooms.
