Wine Cap Mushroom Overview

Stropharia rugosoannulata is an edible mushroom species found naturally in garden beds, on lawns and forest edges. It is quite easy to cultivate and is grown commercially. It can enrich soil and suppress weeds. Unlike most other mushrooms, the King Stropharia is best grown in full sun or partial shade. It has wine red to reddish-brown caps, hence the common name Wine Cap Mushroom. Another colloquial name is the Godzilla Mushroom, this name refers to the size this species can reach, it may reach 20cm in height and 30cm in spread. It has pale gills, which develop to a grey shade and finally a dark brownish-purple colour. Once cut open, the mushroom should have white flesh and the stem a wrinkled ring around its circumference.
