if present, the stalk is very reduced, no more than 1mm tall. i’ve no meaningful ascomycete references on hand, so someone else will likely have more to offer than me.

seeing B. citrina proposals on micrograph-less, yellow, lignicolous, discoid asco observations triggers a kind of automatic “err on the side of caution” response in me. alas, it’s not a response I can reinforce with much ascomycete know-how.

The Audubon Society ID book describes Bisporella citrina as “very small, bright lemon yellow cup on short, thick, stalklike base” That’s the main reason I chose that. I’m not denying your correctness and will certainly look into the sites you’ve suggested! Thanks!

is not stalked. This could be a Hymenoscyphus or something similar. AscoFrance is a wonderful resource for finds like these, though microscopy is oftne required to arrived at a species ID.
