Observation 130595: Dendrocollybia racemosa (Pers.) R.H. Petersen & Redhead
When: 2011-11-05

Notes: Found in Panther Creek Camp, growing in humus.

I didn’t notice the branched fruitbodies at the time of collection, but one of them shows in the picture taken at home on the grid paper. (I cannot find it in my ziplock bag now.) None of the mature specimens shows any branching, though the microscopy on them fits the description of D. racemosa completely.

Spores with apiculus, inamyloid, 3.5-4.5 × 2-3 measured fresh; today 5-5.5 × 2.5-3. Basidia 4-spored, ~22+3 x 5. No cystidia. Clamps conspicuous in all tissues. Pileipellis a cutis.

Thanks for pointing this out and for sharing your photo. C. cirrhata seems consistent with the microscopy I’ve got here.

of D. racemosa with C. “tuberosa”

It looks like a mixed collection

of a Collybia (maybe C. cirrhata) with the Dendro coming up next to it. Something I have observed many times in northern CA.
