Stropharia rugosoannulata - Wine Cap Genetics

Scientific Name: Strophoria rugusoannulata 

Common Names: King Strophoria, Garden Giant, Wine Cap, Godzilla Mushroom

Description:  A delicious gilled mushroom with a very large fruitbody, distinctive red-burgundy cap, and a thick partial veil that leaves a skirt on the stem.  This is the best choice to grow on outdoor woodchip beds, and is rather difficult to grow indoors because it requires bacteria to initiate mushroom formation.  Outdoor mushroom beds often form single mushrooms over a pound and up to 5 pounds!  Because of its high yield outdoors on both woodchips and straw and ease of identification it is the best choice for outdoor growth

Harvest Hint:  For indoor growth a pasteurized casing of straw or peat (50-60 deg C max) must be used to provide bacteria, and the process is still slow and unreliable compared to oyster mushrooms.  Leave bag walls 3-5 inches high to promote longer stems.  Indoors or outdoors harvest mushrooms before or immediately after the partial veil breaks exposing the gills.  These younger mushrooms have a longer fridge life and superior taste and texture.
