Observation 87841: Mycenastrum corium subsp. ferrugineum O.K. Mill., R.-L. Brace & V.S. Evenson
When: 2012-02-09
(37.876868° -122.26418° )
Herbarium specimen reported

Notes: The first photos are of a young specimen. On 2/13/12 Else Vellinga picked up an old specimen that was lying loose at the same location. It had powdery orange gleba. She looked at it under a microscope at UC Berkeley on 2/15/12 and found the capillitium to be spiny, and the spores to have developed a yellow-brown wall with ornamentation. She determined this was Mycenastrum corium subsp. ferrugineum.

Over the next two months about 12 more have come up at that location – a traffic island with curbs on either side and dirt inside, north of the UC Berkeley campus.
