and so the internet mushroom photo telephone game goes.

widespread in NA though this taxon may be, its identification based on macroscopic likeness to photos online is potentially hasty. for decades, the name D. concentrica disguised the true identities of dozens of taxa, all of whom shared the basic, genus-level Daldinia features. we now know (largely thanks to the SIM paper) that the genus is far more diverse than previously considered, and species-level IDs, when obtainable, tend to require some combination of knowledge of ascospore morphology, apical apparatus size/shape, KOH extractable pigments, perispore dehiscence in KOH, host, conidiogenesis type, and secondary metabolites.

I wish I were a specialist in this group, or any other group, sufficient to say, definitively, what something is or isn’t based on the available information, even if the only information available is a location and a field photo. instead, I continuously find myself in the role of the cautionary naming police, fighting against the rising tide of popular mycology, which insists that a smart phone picture and a color plate from audubon are enough to ID anything to species.

TLDR: we need experts. with or without them, being thorough is the best way to make good identifications.
