Observation 68310: Stropharia rugosoannulata Farl. ex Murrill
When: 2011-05-28
No herbarium specimen

Notes: Cap only about 1 inch diameter. I have previously found this small type on my lawn, which is where I found this one. Stipe seems too long for S. coronilla, and ring too persistent for S. semiglobata. Has the overall appearance of a miniature S. rugosoannulata, except the cap color is yellow or beige. Spore print very dark purplish, almost black… purplish/brownish tint barely observable against a black background.

both the burgandy and the yellowish versions, often occurring within the same patch. I have always thought that the yellowish ones were faded. The odd thing here is the small size of this solitary fruit body. In years past, I have also found the large burgandy/yellow ones either growing in our compost heap or from the ground nearby decaying piled leaves. Hamilton’s suggestion makes sense to me. The little ones (solitary and on the lawn) have less available nutrient.

Spore size… average about 11.5 × 7.5 mu (the micrometer on my scope registers a bit low)… fits well within the range for rugosoannulata. And spore print color is exactly as described in several manuals.

Does anybody know if that is normal or is it a common occurence??

a picture of the spores, and a ruler – so what is the spore size, and what do the cystidia look like?

I find them along a creek near me, along with the regular colored ones. I think they just may be weaker fruits that don’t have the optimum conditions to look normal.

on my lawn, several times over the past 5 years. Cap diameter is always in the one inch range. Such small examples of rugosoannulata seem odd to me.
