greenish disco with globose spores, red subiculum?

Hello,

I found a discomycete recently on a bare hardwood branch that I had left in my backyard in Brooklyn.  They are very small (and hard to photograph), each less than 1/2 mm.  They are greenish with a lighter green margin, seem to grow associated with a red staining in the wood (though I suppose that could be bacterial).

Asci IKI+, 35-43 x 4-5µm... to me they look like there are croziers.

Spores are globose or nearly globose, with a single guttule, 2.5-4 x 2.5-4µm.

Hairs look somewhat enlarged at the tips and slightly encrusted.

Does anyone have any suggestions?  Thank you in advance.

Ethan

Re : greenish disco with globose spores, red subiculum?
This is Hyphodiscus theiodeus. It usually grows on Peniophora but also on bark and wood.

Thanks!  That looks like a match!
