On sagebrush, Artemisia tridentata, at the base of the foothills.
Appears abundant.
Size 3.5 x 2 cms.
Pores angular 3-4 pores per mm. (pic 4, caliper opening 5 mm).
Spores broadly elipsoid, smooth, hyaline, (5.5 - 6.3) x (4.2 -5.0) This is a little larger than described.
Basidia broadly ovoid 10-12 x 6-8 (Pic7, basidia looks like spores but is a little larger and elongated, count 3+)
Setae rare, thick walled, ventricose with a sharp point 24 x 9. (Pic 6)
The sample has some Xanthomendoza lichens on it, if selecting for DNA sampling, care should be taken selecting a contaminant free sample. Contaminant spores are visible on pic9 (last) with some two septa foreign spores.
