Observation 5677: Galerina vittaeformis (Fr.) Earle
When: 2007-12-01
No herbarium specimen

Notes: These were found at the edge of a grassy area, in among some moss, but also small woody debris. One of the caps was found attached to the woody debris, but it was not sure if these were attracted to the grass, moss or woody debris. In general it seems Galerinas like all three, but different species like different amounts of each.

Anyway, these had light brown caps, and long fibrous stipes which darken from the base. There was no evidence of any veil on the stipe, although the stipe does have long fibrous hyphae on it, there isn’t a fibrous zone at the top.

The first micro-shot shows the cheilocystidia at 400x in Meltzer’s. The cystidia are not capitate, and not clubbed. They are finger-like with wavy side walls. This also displays the spores are long and narrow, and dextrinoid.

The second shot is of a radial section of the cap at 400x under water. The cap surface does not display a gelatin layer, and the parallel hyphae of the cutis. But also important there are no pileocystidia displayed here.

The third micro-shot is of a spore at 1000x under oil in KOH. This spore was taken from the stipe surface. The spore is long and narrow, 11.3 × 6.1 um on 10 spores measured. Also the spore is only slightly roughened.

This, with the ’shroom size, make this G. vittaeformis, and beyond that, in the Smith and Singer monograph this is also the form vittaeformis of the species. (There are other forms.)

This species is closely related to G. atkinsoniana, which is comparable to all features, except the pileipellis displays many pileocystidia. This surface of cystidia on the cap I’ve been told can be seen in the field with a hand lens, although I haven’t found these yet.
