Observation 6705: Deconica inquilina (Fr.) Romagn.
When: 2008-02-02
Herbarium specimen reported

Notes: Some small Galerinas to add to the list. These were found in the rain, in a grassy spot, with some buried moss deep in the grass. The caps seem to be attached to the dead grass, more than the moss.

The caps are viscid, but then again it was very wet out. The smallest cap seems to have veil fragments on the cap margin, although these are gone from the mature caps.

3/15/2008 – Getting back to these guys, and got them under the scope.

The first micro-shot is of the gill edge at 400x in Meltzer’s. Here you can see the cheilocystidia on the non-fertile gill edge. They are short and pointed. The spores here are dark, and non-dextrinoid, and inamyloid.

The second micro-shot is of the cap surface in a radial section in Meltzer’s at 400×. The pileipellis is an ixocutis.

The third micro-shot is of the spores from the stipe apex in KOH at 1000×. Here the spores are brown, with thick walls, smooth, and with a germ pore.

The non-dextrinoid dark smooth spores, with a germ pore, and the cutis means they are not Galerina, and I’m going to start putting these into Psilocybe. (Does that mean I have to start looking up the monograph by Guzman here…)

3/22/2008 – Ok, now I’ve looked up the monograph by Guzman, and the section of Psilocybe is pretty obvious for these, but the species, I’m still not sure. I’m going to call these P. montana, and it mostly seems to fit, except these are too light a brown, P. montana is a common temperate forest Psilocybe, that is dark brown. There also is P. physaloides, which has been studied from California by Guzman, which is supposed to be a lighter brown, with shorter cystidia, and thin walled spores. Or as he says “moderately thin walled, with a more or less broad germ pore”, love the definite descriptions in these things. These spores, I am guessing are “moderately thick walled”, so I’m going to leave them as P. montana (which is the more common one), until someone can show a different observation of one of these two species.

it’s still Galerina?

I added the Psilocybe to the name, and put Galerina as “not likely”, but the species listing here is still Galerina for the obs?

When does the obs. species name get updated? Other times I added a name, the obs. name changed right away.
