a mycorrhizal species inhabiting the almost degraded bedlog. It is difficult for some people to understand this: some mycorrhizal fungi require well-rotted wood to survive. Coarse wood debris also provides a water reservoir for living trees nearby. For more information about this, see Chris Maser’s The Redefined Forest.

I don’t have Beug’s Ascomycetes of North America.

I am all for Otidea

Can you make a suggestion of species from the Ascomycetes book? (Beug)

I did not consider it for this observation and you make an interesting suggestion. I did see what I am calling Otidea unicisa several times in moss at the edge of the trail on that day and two weeks prior. They looked similar to this photo,


but were stunted and dried at the edges. I have seen several non-symetrical Peziza this year in suburban locations; nothing of course, this big.


You are welcome to suggest that they are Otidea, too!

Did you or have you considered Otidea, Martin?

Doesn’t have the circular appearance of cup-like Peziza. Photos 2 and 3 show this well.
