Found on mossy soil in woodland of Corylus, Crataegus and Betula. Size 5mm across and 5mm deep with a small stem. The yellow has been enhanced by my scanner but it was was easy to see in a dark wood on a dull day. My original thought was Tarzetta but the spores, with oil drops, are only 10-12 x 5-6um.
I should appreciate any guidance for further research.

Re : Yellow Cup
Tarzetta species has asci without croziers, so your collection cannot be assigned to this genus. Maybe an Arpinia species...

Re : Yellow Cup
The ascocarp is a bit small - perhaps not fully grown yet -, but colour, spore-size, oildrops and the wrinkled outside remind me of yellow Otidea species ("clade concinna"), former genus Flavoscypha.

Re : Yellow Cup
Yes, you're right Till. Clearly an Otidea species!
Something close or identical to O. phlebophora. See https://doi.org/10.25664/ART-0284

Re : Yellow Cup
Thank you both for your input. I can research further. I would never have thought of this Genus.
