Observation 7788: Calocybe onychina (Fr.) Donk
When: 2008-05-31
Collection location: Eastern Shasta-Trinity National Forest, Siskiyou Co., California, USA [Click for map]
Specimen available
Notes:
These were a new one for me, I hadn’t seen these before. They were found by Dimi, and brought in at the end of the day, I snapped this shot quickly from his collection.
These are “related” to Lyophyllum, where they have the same micro-scopic features as that genus, but this genus is colored where Lyophyllum lacks colors.

I have given this some thought since Dimi presented his pictures – the brownish discolouring on the gills was a little disturbing. A better match with that feature is actually Lyophyllum favrei (has been named Calocybe favrei(!).
The spores in this collection fit well too, 3.5-4.5 × 2.8-3.5µ.
It was described from Central Europe not too long ago, and is VERY rare.
If it is Lyophyllum favrei, I’d say it’s remarkable. Is it known from the USA, or does it have any “sister” species here?
