Black, short-stipitate, cupulate apotechia found on Picea abies resin (still liquid, but with a thin crust on it). Easily rehydrated. Asci 125-170 x 13 microns, IKI-, thin-walled. Ascospores phragmo- or muriform, approx 25 x 5-7.5 microns, apparently forming globose secondary spores. Paraphyses very numerous, in tufts, filiform with slightly expanded apex. Dark excipulum distinctly amyloid in Meltzer. Hymenium pale bluish grey when re-hydrated (in section!)
Can Claussenomyces atrovirens be this cupulate and this dark?
Thoughts appreciated.

Re : Claussenomyces? on resin
I think C. olivaceus because of the roundish conidia.

Thanks, I will check that. I didn't know this was a difference between the two.
