Edit SzilvásyGood morning,
My girlfriend has sent this mushroom, unfortunately wasn't fresh. I refreshed it, but I could only observe spores. Mushroom is embedded in Ceriporia sp. It ressambles Catinella sp., but it was blackhish. 
Spore  size: 10.72-11.08 x 4.06-4.7 µm, smooth with 2 drops oil. Ascus lenght: +-77 µm
Could anyone help with the solution.
Thanks in advance: Edit

Hello Edit,


yes - why not old Catinella olivacea?


I think there is only one species in the genus (?). It is normal that the green colour can only be seen in +- fresh specimens.


Best regards from Lothar

Hello Lothar,

I think no, there are 3 species in IndexFungorum, C. olivace, C. melanochlora,C. nigro-olivacea. Photos are only C.olivacea on Net.
I read on Net C. nigro-olivacea:
https://www.jstor.org/stable/pdf/2479948.pdf?refreqid=excelsior%3Aa99363ef362011d68e635e33eb12032d
".....spores eight,uniseriate; elliptic or elliptic-clavate, usually slightly narrowed
near the middle so as to appear slipper-shaped, continuous, two-
guttulate, pale olive-brown to deep brown, 7-I I x 4-5 ,u (majority
8-io ,u);...."

I think this mushroom maybe C. nigro-olivacea, but am'not sure.
The photo is still made of fresh mushrooms.

Thank your for answer.

Re : unknown asco
Hi Edit

Durand distinguishes two species, and you are right, it fits the first of the two. But In the long synonymy list he included Catinella olivacea as a possible synonym. This means that he was not sure whether Batsch had the same fungus as L. v. S. (or Currey who appears to have validated it). 

Apparently later authors accepted that Batsch dealt with the same fungus and adopted the oldest name olivacea.
