Scutellinia kerguelensis?
Filip Fuljer, 02-07-2017 21:05
Filip FuljerHi there,
i found some Scutellinia last year on wood, in stream with Pachyella babingtonii and i do not know which specie is it. My opinion is that, it can be Scutellinia kerguelensis, but idk. Please i need some advice which specie is it.
Here are some microscopic features:
Hairs - 179-312x15,7-23,2 µm, uni or bifurcate, dark-coloured, septated
Spores-with warts but very hard visible in optic light, ascospores with outer wall not loosening when they are heated in Cotton blue, 19,1-22,3x12,3-14,9 µm
Paraphyses-3,3-4,25 µm broad, on apex 7,2-11,7 µm broad

best regards,
Filip

Re : Scutellinia kerguelensis?
Hi Filip,
would you have more photos of the spore shape and ornamentation? From these so far I would consider S. nigrohirtula as well. The main difference should be in spore form (more broad ellipsoid to subglobose for kerguelensis), but I didn't read yet any clear data as to which species has which length:width ratio). Some authors even considered them synonyms.
Cheers.

Filip
I would agree with Viktorie that I would expect the spores to be more broadly ellipsoid and the ornamentation smaller for S kerguelensis.
S nigrohirtulla is a much better fit but I have only ever seen that with very crowded and much darker hairs.

Re : Scutellinia kerguelensis?
In agreement with Viktorie and Malcolm, but actually an observation on sporée would allow a better appreciation.

Michel.
