Observation 75074: Hemimycena pseudocrispata (Valla) Maas Geest.
When: 2011-07-30
Collection location: Thoiry, France [Click for map]
Herbarium specimen reported

Notes: Found under spruce and fir.

The micro-shot is of the spores from the gills at 1000x in KOH. The spores are ellipsoid, smooth, and hyaline. The apr. size is 9 × 3 um.

These were very small, and dried a cap is about 1 mm in size, kinda hard to create a section on that, so I just plucked off a whole cap and squashed it. This made it hard to tell what was what, so I couldn’t tell what was the cap surface after the squash, it was just all random hyphae everywhere. So, that didn’t help much. But I could tell from some gill edges that no hymenal cystidia were obs., and the basidia are 2-spored.

Looking at that, and the size, the fact they are all white to the base, and they do have lamellae, not just wrinkles, I was able to get an id. Looking in the Antonin and Noordeloos book on Hemimycena, I got to H. pseudocrispata. (Not to be confused with H. pseudocrispula, or I guess with H. crispata for that matter.) It turns out the type location for this was Annemasse, France, just across the Rhone, other side of Geneva from where I found this one. I actually could see Annemasse from where I was on the drive home from here.
