Unidentified Mushrooms of SD

I don’t expect to ID every mushroom that I find and eventually have to set them aside! This is my list of mushrooms that I have yet to ID. If you have any information that might help please send me an email! Also, I generally keep a dried specimen of my unidentified mushrooms if you’d like to study one.

September 26, 2022

Possible ID: Hypsizygus Ulmarius
Habitat: saprophytic on wood
Season: found in late summer
Spore Print: white
Gills: Attached to the stem
Notes: what in the absolute hell? how can a mushroom this big and beautiful (and durable) be so difficult to ID? After I went through two of my older guides I couldn’t find anything to match this mushroom. Then I used Michael Kuo’s key and easily found a 100% match (KOH=negative, growing from scars, etc). BUT! The “ulmarius” name sounded familiar and sure enough one of my former mushroom guides uses Pleurotus Ulmarias to describe a mushroom that “looks like an oyster mushroom”. You can view P. Ulmarias on this page and notice that the cap has a much different flesh. But apparently these two names are synonyms. And according to David Arora it is a synonym with Hypsizygus tessulatus. If three different mycologists can’t agree on this how the hell am I supposed to figure it out?

To make it even more interesting, an almost identical mushroom covered in scales (last photo) was found at the same forest within a week of the original mushrooms.
