To make the most of current knowledge of the “yellow Validae”… EDITED

… (those under discussion this morning), microscopy seems to be a critical element.

Despite a lot of genetic study effort put into the Validae (the relative stability of brunnescens, the apparent circumarctic distribution of porphyria, the segregation of lavendula from two genetically distinct look-a-likes, the recognition of multiple taxa within the North American rubescent group, etc.) there is a very large amount of work that needs to be done. I guess that might be overstating the obvious.

…Newfoundland. I segregated the material looking like the images here, at the time, by spore size-shape. When the material only differed macroscopically from elongata by having an orange region on the cap and the spores were a good match to those of elongata, then I determined the material as elongata.

Very best,

Rod
