a all white scutellinia producing long hair with multifurcate base, and quite heavily ornamented spore (measurement 18-20*11-13u) paraphyse where not observed but that is probably because ascus have collapsed for some reason, and finding paraphyse was now impossible.Any idea?
Collected on rotten wood in Montreal QC, december 2015

Re : white scutellinia
White specimens of Scutellinia are not usual but possible (due to an absence of carotenoid pigments). It would be interesting to see the content of spores (guttules) in living state to confirm the genus Scutellinia. The genera Paratrichophaea and Trichophaeopsis are close and have species with white or pale grey apothecia.
Can you confirm that the spores are ornamented by a network?

Re : white scutellinia
Interesting, the non labelled pictures where in water, so the spore are probably alive there, I can't confirm if there is a network on the spore, but on many occasion I was pretty certain to see it, especially in Melzer.

Re : white scutellinia
Okay, so it's a Scutellinia species and it looks like S. pennsylvanica. The substrate (rotting wood) is also a good character.

Re : white
I have seen S. pennsylvanica once before about 10 years ago, I believe in Maine. It was an orange colored species. I dont know if there are white forms of it? I believe S. pennsylvanica was described from the Yough river near my house. And yet I have never found it here or anywhere in Pennsylvania. Its a species I have been looking for the last 10 years without any luck.

Re : white scutellinia
John, I read somewhere on ascofrance, that sometime oranges scutellinia grow whitish for some reason, apparently thjis isn't too rare for this genera.

Re : white scutellinia
S. pennsylvanica has been found in Europe. See:

Re : white scutellinia
How can you tell that it is a scutellinia by seeing the guttulation?
Nicolas, can you send me that publication please?

Re : white scutellinia
The spores of Scutellinia have spores filled by many guttules, the genera Paratrichophaea, Trichophaeopsis and allies have a different pattern.
