Observation 137499: Stropharia kauffmanii A.H. Sm.

When: 2013-06-06

Collection location: Bassetts, Sierra Co., California, USA [Click for map]

Who: Douglas Smith (douglas)

No specimen available

Found under mixed conifers, growing from the side of a buried log, at ground level.

The first micro-shot is of the gill edge at 400x in KOH. The cheilocystidia are broadly lageniform, scattered on a fertile edge. There are numerous pleurocystidia on the gill face. The basidia are 4-spored.

The second micro-shot is of spores from the gill at 1000x in KOH. The spores are ellipsoid, smooth, and with a very narrow germ pore, only visible on less than half of them. The apr. spore size is 8 × 5 um.

Not sure what to do with this one, and no one else had seen one like this up there before. It looks like a Psathyrella maybe, like a Lacrymaria maybe, but the spore color is more brown, and the spores are smooth. But it also looks like a Pholiota maybe, but the cap isn’t viscid, and the spores are kinda too dark a brown for that one. In Europe there was Hemipholiota, and this one looks a lot like that really, except that one doesn’t have pleurocystidia.

So, still not sure about what to do with this, might work on it some more with sources later.
