Eupezizella aureliella ?
Ethan Crenson, 11-07-2023 20:35
Hi all,

I found these white - orange hairy discomycetes in New York City recently.  I thought that they might be Eupezizella aureliella. 

Apothecia are very small, less than 0.5mm wide, in most cases.  They are clothed in bright white hairs. Some of the hairs are tinged bright orange.  In a water mount the orange pigment appears to be an oily or resinous exudate. The hairs are narrow above and wider at the base, textured and approximately 35 x 4µm.

Asci are very faintly amyloid (unless that's just a refractive ring I'm seeing).  Spores hyaline somewhat fusiform, almost cylindrical, 5-5.5 x 2µm. 

On the bark of an unknown tree.

That's all of the data I have right now. Would anyone agree that this is at least close to Eupezizella aureliella?

Thanks,

Ethan

Re : Eupezizella aureliella ?
Spores should get longer but otherwise clearly aureliella. Is there any wood at the bark to check if it is coniferous?

Re : Eupezizella aureliella ?
Thank you so much, Zotto. I only collected bark pieces. They are thick and chunky like Black Locust, which is what thought the wood was originally. But it's remotely possible that it's conifer. When I return to the site I'll look more closely. I'll also check a few more apothecia (there aren't many) to see that the spore measurements are correct.
