Notes: Found under and near fallen aspen logs.
Love to get a better name on these, they are very cute. Small, only 5-8 mm in diameter in the cap. I didn’t record any specific odor on these, and I don’t remember any, so I’m sure if they had the garlic odor, I don’t think so. They seem fairly distinctive, so I should be able to get a name…
10/1/2008 – Getting back to these.
Well, got these under the scope.
The first micro-shot is of part of the hymenium in Meltzer’s at 400×. Here the layer of basidia is seen, with the cystidia sparsely spaced. The cystidia was observed evenly spaced over all the hymenium. Also nothing here has any reactions to the Meltzer’s.
The second micro-shot is of the stipe apex in KOH at 400×. Here you can see the caulocystidia are dense and short and pointed. The caulocystidia were observed the whole length of the stipe.
Very few spores were seen, but they were there, some connected to 4-spored basidia. They were ellipsoid, and very roughly 10 um long, and hyaline in Meltzer’s.
Putting this together, along with the fact that they were found on aspen leaves, the weren’t that hard to id with the Marasmius monograph in the Agaricales of CA. It seems these are not found much in California, but are common enough on aspen leaves.
