Danny’s DNA Discoveries – Eurotiomycetes of the PNW

Introduction
This class is best known for deer truffles and earth tongues on animal remains. Deer truffles (Elaphomyces) - have a think, warty rind and a cottony/powdery white interior that quickly turns black. Onygena - earth tongues (spherical powdery tan heads with long stems) on animal remains. Arthroderma - whitish irregular spheres on animal remains/dung but without stems. abundant common uncommon rare - colour codes match my Pictorial Key and are my opinions and probably reflect my bias of living in W WA. Rare species may be locally common in certain places at certain times. |

Eurotiomycetes
Elaphomyces asperulus EU - the only species sequenced from the PNW so far. The next 4 species had been reported here, but the modern collections that have been found and sequenced all turned out to be this different species instead. Elaphomyces anthracinus EU - we have the EU type sequence and it has been reported from here, but no verification yet. Elaphomyces decipiens EU - we have the EU type sequence and it has been reported from here, but no verification yet. Elaphomyces granulatus EU - we have the EU type sequence and it has been reported from here, but no verification yet. We do have one environmental sample with a sequence between this species and E. asperulus. Elaphomyces subviscidus OR - no data yet. We need a type sequence and modern collections. Elaphomyces cf muricatus EU - easily recognizable with its reticulated/marbled pattern inside the rind when cut. We have reliable EU sequences and it has been reported from here, but no verification yet. We do have one environmental sequence from BC, but no fruiting bodies sequenced yet. Elaphomyces muricatus EU var. reticulatus EU - differs by having sublter warting on the exterior and subtler marbling inside the rind we have the EU type sequence, and it is 2-3 bp different than that of the type variety. It has been reported from here, but no verification yet.

We only have type sequences of LSU, but read on. Onygena cf equina EU - similar, on animal horns and hooves. We have an LSU type sequence, and a reliable ITS sequence and it turns out it has the same ITS as O. corvina. Arthroderma silverae EU - irregular white spheres on bones inside coyote dung. Not reported here before it was found and sequenced and matched what I think is the type sequence.
