Observation 174441: Gymnopilus P. Karst.
When: 2014-07-30
Collection location: Obetz, Ohio, USA [Click for map]

Notes: Growing on well-rotted maple. In the same area as 174161/174433 but not growing on the same logs. Differentiated from it by yellower stems and scalier caps. Orange spore print. Could be a Pholiota for all I know.

but it would cast doubt on a couple stirps inside that section.

would be great! Thanks! Would the spore print for the Pholiota I found turning brown indicate that it’s not in section Flavidula?

Great!

Thanks! Spore color is usually helpful in delimitating Pholiota from Gymnopilus, but Pholiota section Flavidula has ferruginous spores. I will send you some koh in return for the collection. It will be helpful for some IDs.

‘ll send you these too then. I didn’t see any veil remnants on these. I don’t have any KOH. Would it still do any good on dried specimens? I also have 2 other collections from the same area that I suspect might be the same species. I’ll post observations for those too. I checked the spore print for the Pholiota species that I’d thought was a Gymnopilus, and its orange spore print had faded to brown. Is that a feature that’s useful in telling Pholiota and Gymnopilus apart? The spore print I took for these is still as orange as it started out being.

also like to look at this one. It may well be a Pholiota. There are several Pholiota species that intergrade macroscopically with a small, uncommon group of Gymnopilus. The things that point toward Gymnopilus here, as opposed to Pholiota, are the lack of fulvescent staining on the stipe, smooth gill edges and fibrillose ornamentation toward the margin of the pileus. Of course all of those features are ambiguously variable. If there are yellow, conic appendiculate veil remnants along the pileus margin then consider Pholiota subsulphurea. Do you have koh?
