Collection location: Jemez Mountains, Los Alamos, New Mexico, USA [Click for map]
Actually two collections here, sort of, one found under spruce and ponderosa pine, the other under spruce, d. fir and aspen. It seems that C. amianthinum is a common name for the area, but there seems to be another name and the difference seems to be only spores are amyloid or inamyloid? Or, not sure here, I save a couple and I might check this at some point (or maybe not…).
10/18/2008 – Getting these under the scope. I seem to have gotten sidelined on a small study of Cystoderma of the Southwest here… Anyway…
Decided to pop a few Cystoderma under the scope, and these came up kinda interesting…
The first micro-shot here is of the gill edge at 400x in Meltzer’s. Here there are lots of clear cystidia, which are long, spear-like, and with some incrustations on the ends.
The second micro-shot of a spore from the gill at 1000x in Meltzer’s. The spores are inamyloid, smooth, ellipsoid, without a germ pore (I don’t think I need to add that, I don’t think there are any white spores with germ pores). There were not a lot of spores, the cap seemed to be young. The ave spore size was : length – 4.35 +/- 0.24 (err 0.13) um, width – 2.89 +/- 0.35 (err: 0.16) um – q : 1.52 +/- 0.17, on 6 spores.
This all agree well with Cystodermella cinnabarina. There is a nice study of spore size in the paper ref. here, it seems that spore size is fairly significant here. The spore length here agree well enough, but these spores are wider than the pub. description. Although there were only 6 spored measured, so I’m not sure that means much.
With the cystidia and inamyloid small spores, there is clearly C. cinnabarina. The color of these is fairly brown, maybe a rusty red-brown, but not as red as the ones show here on this site from the northern CA coast. I wonder about those… and it would be good to try and get more from the north coast here, and get them under the scope to make sure they are C. cinnabarina also.
