Michel HairaudBonjour,On me fait part, pour diffusion d une list
yesterday I found something Mollisia-like on a twig of Betula, hiding on inner bark. It was under a rupture in the outer bark caused by a now dead stroma of Diatrypella favacea or something alike.
The diameter of apos are up to 1.2 mm, greyish - yellowish, turning more brown on drying. Asci 35-42 x 4-7 µm, IKI-. Spores 5-6.5 x 1.5. Parahyses simple 35 x 2 µm.
With Gminder's key the closest I can get is Mollisia ceaspiticia. Any chance that I am somewhere close by?
Stefan
HI Stefan,
Your macro and micro match collections of M. caespiticia we regularly make on twigs of Quercus in Brittany, also on dead Diatrypaceae , but hithertoo rather in winter and spring, I.E. during very wet periods.
IKI négative is a striking character of this species

Another idea was that M. caespiticia is a Pyrenopeziza. I just moved it back to Mollisia because their is no evidence at present, and it could also be that my folder includes different species. For the sequenced sample only a macro exists which is in the C. vulgaris folder (6.I.2016).

Gremmen 1958 examined the "type" in H on Sambucus, so this might have been interpreted as lecotypification. But he did not describe it.
I do not see that Huhtinen published on this, how can he have selected a lectotype?
as far as I remember there were two collections in the KARSTEN Herbarium in H, both of which were studied by Seppo as well as by me. I can verifiy tomorrow when I'm at home. And as far as I remember one of them was labelled as Lectotype. Both collections were on Ribes, as far as I remember, but I will check and verify.
best regards,
Andreas
