Observation 7310: Galerina vittaeformis (Fr.) Earle
When: 2007-11-17
Herbarium specimen reported

Notes: Another G. vittaeformis for you, although this one with smaller spores than before in other’s I’ve seen, making these G. vittaeformis var. vittaeformis f. tetraspora. I don’t know, Smith and Singer make this whole thing out of 2-spored and 4-spored basidia, but really if there is nothing else to split the species, are these really split species? Well, they’re published, and I’m not, so go with it.

The first micro-shot is of the gill edge at 400x in Meltzer’s. Here you can see the fusoid-ventricose cheilocystidia, there are also lots of pleurocys. not shown here. The spores are clearly dextrinoid.

The second micro-shot is of spores from the stipe apex in KOH at 1000×. Here the wrinkled surface is clear, and some show a plage. The ave spore size on 7 spores is 8.0 × 5.1 um.

The shorter spores here put this into the form tetraspora, where the form vittaeformis would have an average length between 10.5 and 12 um.
