Observation 57999: Gomphus floccosus (Schwein.) Singer
When: 2010-11-02
Herbarium specimen reported

Notes: Collection # YNP1520 for the Yosemite Fungal Survey.
The spore print on these was ochre and the spores were ~ 11.6-14.0 X 5.8-6.1 microns.
These two and another group were growing in clusters.
The combination of characters make them look like a cross between Gomphus floccosus and Gomphus bonarii.
The spores of G. bonarii are somewhat smaller than G. floccosus(according to the Millers’ book) and these fall in the transition zone.
Will be interesting to find out what DNA tells us.

floccosus & bonarii

Admir Giachini synonymizes bonarii with floccosus in his doctoral dissertation:

Giachini, A. (2004). Systematics, Phylogeny, and Ecology of Gomphus sensu lato. Ph.D. Dissertation. Oregon State University: Corvalis, OR. 446 p.

And it’s now Turbinellus floccosus (Schwein.) Earle.

These did come out of the ground with very white “gills”

and the camera did overemphasize it a bit. However, they did become more buff-yellow with time and were quite Gomphus vein-like. Gomphus bonarii is a western montane species that has been recognized for some time in Western US field guides. In fact, most locals would have labeled this G. bonarii just on appearance and location. However, i believe that there may be some recent evidence that the two species are very closely related, and perhaps essentially identical.

unless that’s the photo’s fault. awfully clean, white gills for a Gopmhus too. never heard of G. bonarii. either of these two characteristics common to that species?
