Observation 34346: Galerina nana (Petri) Kühner

When: 2010-02-08

Collection location: Menlo Park, California, USA [Click for map]

Who: Douglas Smith (douglas)

Specimen available

Found under redwood, in a grassy area. No moss anywhere near by, no obvious woody debris or rotting wood. On edge of irrigated, landscaped, well tended lawn.

These were kinda exciting to find, I’ve been looking for them for awhile. They have been reported from California, but there was not much in the way of details, just random reports. But here they are. They are kinda a half-way species between Galerina and Inocybe, with the thick-walled incrusted metuloid cystidia.

They don’t look like Inocybe though, they look like just another Galerina. Although umbonate, and sometimes acutely. Strangely found in grass, although the amount of woody debris that might be in the soil is unknown, and was at the edge of am area with redwood duff.

The first micro-shot is of the gill edge at 400x in Meltzer’s. Here the incrusted metuloid cystidia can be seen. There are also lots of obvious similar pleurocystidia. Many 4-spored basidia were also obs.

The second micro-shot is of spores from the gill at 1000x in Meltzer’s. Here the spores are ellipsoid, pointed, roughened, dextrinoid, with a clear plage seen on most. The spores are apr. 10-11 um long.
