Common Names: Wine cap stropharia, garden giant, burgundy mushroom, king stropharia, godzilla mushroom, Japanese: saketsubatake
The king stropharia can grow to 20 cm high with a reddish-brown convex to flattening cap up to 30 cm across. The gills are initially pale, then grey, and finally dark purple-brown in colour. The firm flesh is white, as is the tall stem which bears a wrinkled ring.
It is found on wood chips and bark mulch across North America in summer and autumn.
