OK for O. alutacea

O. alutacea in fresh state is always light brown (alutaceous) in all parts. If you have any doudt you just have to control the spore shape: it is “oblong”. The typical length is between 13.5-15 µm.

looks good, with the right shape and colour of the ascocarp, and right shape of the spores (more cylindric than most other Otidea-spores).
Spore size? Not sure about the magnification here..

micrographs added.
