my understanding of B. mottiae was that it was mostly unfounded as a separate species – it is suppose to be a B. fibrillosus look-alike with a wrinkled-reticulate cap (which is easily explained by environmental weathering in most specimens), and white instead of yellow pores when young (which is ridiculous, since B. fibrillosus has white pores when young).

Sounds pretty thin as a species to me.

what makes it fibrillosus instead of mottiae?

i keyed it out in an old Pacific NW Key Council key, but then when i tried to look into the name online it sounds like the concept of “mottiae” as a species is now being generally disregarded. are specimens which key to mottiae now being considered more properly called fibrillosus?
