Stropharia rugosoannulata
Key to Gilled Mushrooms KeyThis is a key to gilled mushrooms, that is, mushrooms having a definite cap with a fertile surface consisting of gills. The fruiting body usually also has a stem, although that may be lateral or absent (usually, then, the mushroom is growing from wood). You can use this key to identify mushrooms that you find.
Agaricales OrderFruiting body containing fibers (usually in the stalk)
Black Spored SuborderSpore print black, very dark brown, purplish black, or dark purplish brown, but not fitting the Gomphidiaceae
Gills usually light grey, becoming black from spores only when very mature
Stropharia GenusAll brightly colored, large (cap more than 3-4" across), substantial black-spored mushrooms go here.
All slimy-capped non-Gomphidius black-spored mushrooms go here
All non-Coprinus black-spored mushrooms with a persistent ring on the stem go here
All non-Coprinus black-spored mushrooms with white rhizomorphs go here, and all Stropharias should be assumed to have them unless specifically mentioned
Stropharia rugosoannulata (Farlow) Murrill
Here are the characters that distinguish this species from the others in its group. For its more general characters, see higher up on the page.
If there's just a few words or a microscopic feature here, a more thorough description can be found above.
Diagnosis
- Cap up to 6" across; vinaceous, fading to tan
-
Gills crowded, white when very young, becoming greyish-lilac and eventually black
-
Annulus thick, striate on its upper surface; often spiky, at least on its lower surface: it looks like the stem has impaled a sunflower
