Observation 4907: Conocybe Fayod

Ah, a new Galerina found this week, that I haven’t seen before. Found in the same area as the G. tibiicystis, swampy area with lots of moss and grass, and various herbatious plants. These are different in the caps are darker, the stipes are lighter, and they have a veil half way up the stipe. This gills are a dull yellow-brown, which points to Galerina (and the caps look to have a cutis), but I’ll have to get details under the scope to make sure.

12/17/2007 – Spoke too soon on this one, it looked like a Galerina, and took me forever to get back to it under the scope. But finally did get it under the scope, and got to the point where I am checking the radial section of the cap to see details of the cutis… and ooops, not a cutis. These have a hymeniform pileipellis. Dr. Desjardin looked at these, and said oh, yeah, not a Galerina. It seems that Galerina won’t have a white stipe like this, or a membranous veil in the middle like that.

The micro shot is of the pileipellis (surface of the cap), at 400x under water, and this was a radial section. This shows the hymeniform surface, with a series of cells pointing upward away from the surface in a single layer. The cells apear colorless on a pigmented layer, and this creates the hygrophanous surface, as the cells dry out the light getting to the pigment changes.

So, unknown Conocybe here, a Galerina would not have this type of surface cells.
