Mollisia albogrisea

Hi, I have collected this ascomycete in a constantly wet and rather cold locality in the Czech Republic, on a twig of a deciduous tree, still with some bark.
Using the key to Mollisia by Andreas Gminder, I´m coming to point 18 in the subkey "wood, bark". Then, the best possibility is M. albogrisea, although the apothecia in my collection cannot be described as white.
Key characters: Ascospores (9.1) 9.7 - 11.3 (12.1) × (2.3) 2.5 - 2.7 (2.9) µm, Q = 3.4-4.6, Me = 10.3 × 2.6 µm; Qe = 4, OCL = 0-1, 1-celled.
Asci (62.1) 67.2-70.7 (75.1) × (6.9)7-7.6 µm, IKI bb, H+.
Subhymenium built of hyaline hyphae.
Very distinct yellow reaction in 5% KOH.
Do you agree with my identification?
I have read a discussion here at ascofrance, and if I understand it well, Mollisia albogrisea was a nom. prov., but the species was later described as Phaeomollisia piceae and then combined to Phialocephala piceae.

Re : Mollisia albogrisea
Hi Zuzana
I asked Ingo Wagner and he tends to accept this ID. For comparison he sent a link
At least the marginal ectal excipulum is hyaline in your sample. M. albogrisea is well-explored by ITS sequences, and sequences of the anamorph Phialocephala picea have a strong match. Even ITS1 or ITS2 alone would be enough to confirm the species.
Since there is a Mollisia piceae (Pers.) Quel. which is of unclear identity, a new name must be proposed when not splitting Mollisia in several genera. Gminder's name albogrisea would be a good cbhoice in our opinion.

Re : Mollisia albogrisea
Hi Zotto,
thank you and also Ingo.
Yes, both our collections look +- the same.
Sequencing could surely help, but we don´t have a budget to sequence everything :-) I will think about it.
Best, Zuzana

Re : Mollisia albogrisea
Dear Zuzana,
I also think that Mollisia albogrisea fits well for yur collection. The species is not always white or very light grey, but sometimes it can be deep grey.I prefer to maintain the name Phialocephala picea, as I think its better to split Mollisia to several genera than to keep one large genus Mollisia.
all the best,Andreas
