Notes: Found in an irrigated lawn. I asked nicely if I could pick mushrooms in the person’s front lawn, they said of course, feel free. Its nice to be nice.
8/02/2008 – getting back to these.
These are the common grass dwelling Conocybe, but I thought some micro-details recorded here would be nice for comparison.
The first micro-shot is of the gill edge at 400x in Meltzer’s. There were few cheilocystidia obs, but the ones seen were lecythiform (Conocybe-like). The gill edges seemed a bit beat up in this one. Either they were snail-munched, or it mentions that the gill deliquesce in age, and that might be starting.
The second micro-shot is of the cap surface at 400x in Meltzer’s. There the surface can be seen to be cellular, and there are apear to be some pileocystidia, but not many. I was trying to get a thin section here to have the surface in cross-section. But it looked like the cap was only a few cells thick, so it would be very hard to get a thin enough section.
The third micro-shot is of the stipe surface at 400x in KOH. Caulocystidia are seen here, and this is very important in determining Conocybe species. Here there are pointed, and blunt cystidia, intermixed with long filiform cells. This seems to be the almost unique character of this species.
The fourth micro-shot is of spores from the stipe apex at 1000x in KOH. They are brown, ellipsoid, with a germ pore and smooth.
Also in other looking, there were 4-spored basidia, with a few 3-spored.
This all points to Conocybe albipes, which was Conocybe lactea. But it turns out in Flora Agaricina Neerlandica that the author there equates a Friesian species Agaricus apalus (1818) with these, making these now: Conocybe apala var. albipes.
