Scutellinia on mud

Malcolm Greaves, 04-06-2013 00:27

This Scutellinia was found on recently turned soil from a ditch clearance.
5mm across with hairs up to 400 um x 25
Spores average 18.8 x 13.3 with large isolated warts.

Is this S umbrorum?

Thanks
Mal

Re : Scutellinia on mud

Cher Collègue,

Avez-vous chauffé (jusqu'à ébullition) les ascospores en présence de bleu coton lactique pour contrôler si la paroi sporale externe se décole ? Si oui, je pense à S. torrentis.

Cordialement

René

Re : Scutellinia on mud

J'ai trouvé hier une espèce semblable qui s'avère être S. subhirtella. j'ai consulté entr'autre les fiches dans la base de donnés. La base fourchue des poils est un element que je vois sur la photo.

Thanks. I tried boiling in LCB and could find no sign of the outer wall loosening but it did show the ornamentation well. Some warts were up to 2 um across and 1.4 high.
