Observation 46716: Ripartites tricholoma (Alb. & Schwein.) P. Karst.

When: 2010-06-07

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

Who: Douglas Smith (douglas)

Specimen available

Notes:
Found under mixed conifer forest. Found at the Wild Plum campground, Sierra City.

These are different than when I found these before in the area. First time I saw them (also obs. here at the site…), the cap surface was fairly fibrous, with fibers over hanging the margins. This one here has a pretty much glabrous pileus. But we put a gill quickly under the scope, and confirmed the spores for the species here.

These look a lot like the Ripartites metrodii I saw in Geneva, I think it was mentioned that these species are perhaps synonymous.

This time I saw that the mycelium a the base was rather pinkish, and with rhizomes.

Only the third time these have been obs. in the history of the course.

a DNA-comparison between the Ripartites species/forms. I don’t think anything has been done with this genus yet, and I suspect that it has something to do with confusion around the forms metrodii and helomorphus.
