Stropharia rugosoannulata, commonly known as the wine-red stropharia,[2] wine cap stropharia, garden giant, burgundy mushroom, or king stropharia, is a species of agaric mushroom in the family Strophariaceae native to Europe and North America. It is regarded as a choice edible.

Etymology

The specific epithet, which means "wrinkled-ringed", is a reference to the wrinkled annulus of the fruiting body.[3]

Description

The mushroom can grow to 20 centimetres (8 inches) high with a reddish-brown convex to flattening cap up to 30 cm (12 in) across,[4] the size leading to another colloquial name godzilla mushroom.[5] The gills are typically adnate, initially pale, then grey and finally dark purple-brown in colour. The spore print is dark purple-brown to black.[2]

The firm flesh is white, as is the tall stem, which bears a wrinkled ring.[3]

Similar species

It can resemble some members of its genus, such as S. hornemannii, as well as Agaricus (the gills of which are usually more pink).[6][2]

Distribution and habitat

The species is found on wood chips across North America in summer and autumn.[6] It is also found in Europe, and has been introduced to Australia and New Zealand.

Ecology

Paul Stamets's book Mycelium Running cites a study by Christiane Pischl showing that the species makes an excellent garden companion to corn. The fungus also has a history of being grown with corn in Europe.

A 2006 study, published in the journal Applied and Environmental Microbiology, found the species to have the ability to attack the nematode Panagrellus redivivus; the fungus produces unique spiny cells called acanthocytes, which are able to immobilise and digest the nematodes.[7]

Uses

Described as a very tasty edible mushroom by some authors,[2][8] it is easily cultivated on a medium similar to that on which it grows naturally. Antonio Carluccio recommends sautéeing them in butter or grilling them.[5]
