Scutellinia on Quercus wood

gain


This Scutellinia was collected on an old fallen trunk of Quercus robur, somewhat in dry situation, not near to the soil. The hairs 350-1200 x 35-60 are multifurcate with a very broad base. So I think it could be Scutellinia olivascens (hairs fide Schumacher: 150-960 x 18-48).


The attached Cooke's plate seems to fit well with my collection


What do you think?


Many thanks again

Re : Scutellinia on Quercus wood
Good evening Enrique.

Again it is difficult to determine with certainty; I would eliminate S.crinita, but I would hesitate with S.pilati which is also close to S.olivascens. The ornamentation of spores S.olivascens is less dense than S.pilati. The place also seems to correspond best to S.pilati for S.olivascens (humid places ).


Amitiés.


Michel.

Hi Michel


I think, as you, it is not crinita by the type of hairs. It could be S. pilatii but the ascospores 21-27 x 13-16 (fide Schumacher), vs 20-22 x 12-15, seem to be somewhat different.


Thanks a lot

I agree with Michel, the hypothesis of S. pilatii cannot be excluded although the spores seem too small... The crests on spores of S. olivascens are usually "thicker".
