Re : Scutellinia kerguelensis
Hello Savic.
La finesse de l'ornementation des spores et la base des poils font penser effectivement à S.kerguelensis, mais pourais tu observer et mesurer des spores mûres en dehors des asques.
Cette observation est très importante.
Michel.

Re : Scutellinia kerguelensis
Thanks, unfortunately there was no free spores. I measured the biggest spores in asci.

Beñat said that it is a species which has many interpretations and is almost certainly a complex. Even Schumacher has pictures of spores broadly ellipsoid (to almost sub-globose) from the lectotype and much more ellipsoid, like yours, from another sample. In both cases though the ornamentation is very small but covers the whole surface whereas your specimen shows better difined warts.
As Micael says in his post mature ejected spores are important as they can be anything up to 6µ shorter and 4µ narrower once released from the asci.

Re : Scutellinia kerguelensis
I cannot imagine that the true S. kerguelensis grows on woody substrate.

Re : Scutellinia kerguelensis
Thanks Malcolm and Nicolas,
If something worth, the substrate was very wet and very rotten wood.

Re : Scutellinia kerguelensis
Good afternoon to all,Â
I'm just beginner with Scutellinia so this is perhaps a completely wrong idea, but what speaks against S. nigrohirtula? The irregular and rather big warts and hydrophilous habit seem similar.

You have not got "completely wrong idea". Many of the features of this find are a good match for S nigrohirtula. The reasons I am not convinced is that for S nigrohirtula I would expect the hairs to be very dark and densely crowded around the margin and the spores more broadly ellipsoid rather than ellipsoid. I have not got the experience to draw the line between some species yet so others may disagree with this idea.
