Observation 7913: Ripartites tricholoma (Alb. & Schwein.) P. Karst.
When: 2008-06-02
Herbarium specimen reported

Notes: These were a new on me, Dr. Desjardin took these are has put in the SFSU herarium for future study. These were only found up there once before, a few years ago, and now again. I had almost dismissed them as yet another ubiquitous Clitocybe albirhiza, of which there were far too many on the hill side. But these were too small and slender for that. The caps are very fibrous, and shaggy. But the key feature was the spores, they were sub-globose and distinctly ornamented, I said they look like they had a bad hair cut. Interesting little guys.

6/24/2008 – Adding a shot of the spores, at 1000x under oil. This was one of the better shots of a spore, it was hard to get the ornamention in focus. But here you can see the spore is subglobose, and warted. The warts are rather large, and seem to point away from the apiculus. Giving it a star-like appearance, or like the spore has a bad hair cut.

The closest relatives of Ripartites have been beleived to be found in the genus Lepista, but I don’t know what phylogenetics say about it now.

Where does this one fit in?

I think the closest relative is Pseudoclitocybe cyathiformis.

Not sure about this one.

It was not found near water, but in sandy soil. And it seemed to not like duff, only the bare soil, I found them in these small holes through the duff, coming out of the holes. I id’ed these guys with Dr. Desjardin at the scope, and I’m not sure what these guys are related to… The spores are white, inamyloid, non-dextrinoid, but with funny ornamentations. He has some source there that listed the species, but I’m not sure what it was, I just took a few notes, and moved on, there were other guys to get under the scope.

They were a new one for me.

Any related genera that we’d actually recognize? Very cool fungus…was it found near water?
