Scutellinia on mud
Malcolm Greaves, 24-06-2017 23:53
Malcolm  GreavesA group of four or five Scutellinia were on the muddy edge of a run off area of some marshy ground.
They had short pale hairs up to 500 long by 30 wide, simple or bifurcate roots and 4-6 septa. The first few spores looked to have mostly individual warts and were 19-20.5 x 12-14. This lead to a tentative id of S subhirtella.
To make sure about the spore ornamentation I made a spore drop and found that the warts were more amoebic and many of them (without resorting to heating) had the outer wall already loosening. The hairs were unusual shapes.
If I ignore the loose perispore S olivascens is the nearest match but it does not look right for that. Accepting the loose perispore gives S superba or S torrentis and neither of those are a good fit.
Can anyone help.
Thanks
Mal

Re : Scutellinia on mud
Cher Collègue,

Je pense à S. superba (Velen.) Le Gal., S. torrentis à des ascospores beucoup plus étroites.

Cordialement

Thanks René
I was just concerned that the hairs were a bit too long but everthing else fits.

Avec les poils, il peut y avoir des variations de longueurs, également dans d'autres genres
