Observation 11601: Galerina vittiformis (Fr.) Singer

When: 2008-08-19

Collection location: Jemez Mountains, Los Alamos, New Mexico, USA [Click for map]

Who: Douglas Smith (douglas)

Specimen available

Found on moss on the ground, near a rotting log. Near d. fir, spruce and aspen.

The first micro-shot is of the gill edge at 400x in Meltzer’s. The cheilocystidia can be seen here, and they are fusoid-ventricose, with acute to blunt apecies. Also, somewhat, the dextrinoid spores can be seen here.

The second micro-shot here is of the stipe apex at 400x in KOH. The caulocystidia can be seen here, and these caulocystidia are seen also at the base.

The third micro-shot is of spores from the stipe apex at 1000x in KOH. Here the spores are pointed, clearly roughened, and almost in this shot a plage can be seen on few.

The spores here are on ave. a little less than 10 um, also on the gill face 4-spored basidia were observed.

Putting this together these are Galerina vittaeformis var. vittaeformis f. tetraspora.

Personally, I think in other places in this genera, and in other related genera, the separation of 2-spored and 4-spored basidia is a feature that separates species and sections. I think that here in this species, the difference between the 2-spored and 4-spored forms should be raised to variation level, and not just forms of the species. I’d like to simplify here and call these G. vittaeformis var. tetraspora, but I guess that is not up to me…
