Observation 51174: Agaricales sensu lato

When: 2010-08-15

Collection location: National Park Berchtesgaden, Germany [Click for map]

Who: Douglas Smith (douglas)

Specimen available

Found under mixed forest, mostly spruce and oak.

Adding some micro-details:

The first micro-shot is of the gill edge at 400x in KOH. The cheilocystidia are broadly lageniform and thin walled. There are also similar and numerous pleurocystidia.

The second micro-shot is of the cap surface at 400x in KOH. The cap is a cutis, no gelatin, no pileocystidia. The hyphae are pigmented, with no encrustations.

The third micro-shot is of spores from the gills at 1000x in KOH. Ok, not a good shot, there weren’t that many spores floating free, and it was hard to get good shots. But you can see a few spores here, and they are hyaline, phaseoliform and thin-walled. The apr. size is 7 × 3 um.

I thought this was a Pluteus, on wood with free gills, it looked pretty good for another small Pluteus. The cystidia and cap surface also look very good as a Pluteus. But then there are the spores. When the ‘shroom was dried, the gills stayed rather white to off-white, usually they go deep tan to pink-brown in Pluteus. I think this is a white-spored mushroom, so it is not a Pluteus. I’m not sure where to go with it for there, to many random white-spored genera. The keys just kinda point you to Gymnopus, which could mean anything at that point. I didn’t really see anything in Gymnopus with phaseoliform spores, but I’m not sure all Gymnopus are really keyed out. So, yet another unknown little white-spored guy.
