These orange fruit bodies were growing as caespitose clusters or singularly in a deep layer of decaying raked hardwood leaves, mostly maple. The stipes buried in leaf litter easily broke away from the variously-shaped caps; cuplike, broadly concave, nearly planar, convex, with wavy or irregular margins. Disturbing them in situ caused spore-clouds to rise into the air, ala-Peziza. Two collections represented, one when they were first seen on 5-29 and another on 5-30.
Spores smooth, ellipsoid, thin-walled, many biguttulate (more numerously for those from the 5-30 collection), 9-13 x 4-5.5.
Asci not amyloid, with 8 spores.
Paraphyses thinly stretched-clavate with slightly enlarged apices.
I scoped the spores mounted in each of cotton blue and Congo red (from prints on a slide), In Congo red the guttules are more eident.
Observed in Northeastern Pennsylvania, USA.

Re : Seeking ID
Hi David,

are you sure the spores are smooth? A larger magnification of the spores would be nice.

Maybe it is a Sowerbyella.

Regards

Martin

Re : Seeking ID
I am not certian the spores are smooth, although when viewed through my better binocular scope I did not detect ornamentation (at 400x). The two Sowerbyella species I compared have larger spores. The spores from my collection are ceertainly mature; the fruit bodies puffed clouds, and the spoores I examined/photographed come form a spore drop taken on a slide. 9-13 x 4-5.5, biguttulate.

Re : Seeking ID
Thanks you, Martin! I'll have sime time this evening to use the key.

Re : Seeking ID
I think this looks much like Sowerbyella fagicola, macroscopically. The spores should be ornamented then.
Yours, Lothar

Look at the genus Acervus

Re : Seeking ID
I used the key and, although there are no exact matches, using the criteria spore dimensions, color of fruitt bodies, and habitat favoring deciduous trees (litter), I have three that at least lead in a favorable direction: S. radiculata var. kewensis; S. polaripustulata; S. brevispora. The latter seems to be the best fit, although the described color of the hymenium (both fresh and dried) is darker than for my observation. 

I used the following chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/https://www.funga.fi/Karstenia/Karstenia%2024-1%201984-4.pdf . This document also mentions that S. brevispora has cyanophilic spores, which was observed for tthe spores I mounted in cotton blue. This featire was best seen through my better binocular scope that shows color fairly well 9nit pictured).

Re : Seeking ID
Thanks you for the suggestion, Nicolas. The information I found on Acervus describes smaller fruit bodies and spores with significantly different dimensions (much smaller than mine).
David Wasilewski, 04-06-2024 15:32
Re : Seeking ID
Morphology fits S. fagicola well. But the spores dropped by my fruit bodies are significantly smaller than what is reported for S. fagicola; ie. for my spores L<13, for S. fagicola L>17.
