Hi Dr. Lodge,

and thanks for your comments. I agree that there’s some significant variation not only between your DR-1037 collection and the material in the UNF13 species list, but between and among list members themselves. I see differences in intervenosity/anastomosing in the gills, gradations of hairy and smooth and different thicknesses in the stipes. Image 738313 shows what I can only assume are large cheilocystidia, a trait I’m not sure if either C. aurantium or other UNF13 list members share. Maybe a product of environmental variability within a single sp., maybe a sign of multiple spp. As always, a collection in hand is worth two in the internet bush.

My suspicion is mostly general gestalt-based, particularly with regard to the short-shaggy, centrally-depressed, burnt orange pileus and roughly concolorous stipe they all seem to share. Hopefully we will be able to get our Bolivian material loaned sometime this century. In the meantime, it may be possible to have someone perform a quick KOH spot test on the pileus surface.

The stipe is too hairy and the lamellae too thick – check Cyptotrama

The pileus resembles Callistodermatium aurantiacum ined, but the stipe is too hairy and the lamallar edges are too thick. It might be related to or the same as Cyptotrama asprata, or it could be related to Callistodermatium aurantiacum.
