Mollisia albogrisea?

Might've I found M. albogrisea this time?
The substrate is a fallen, decorticated branch of a deciduous tree located in a moist depression.
KOH vivid and lasting yellow; spores 10.1 - 12.4 × 2.4 - 3.1 µm, many with some tiny oil drops.

Re : Mollisia albogrisea?
I await Zoto's opinion, but I would say yes, currently Phaeomollisia piceae or Phialocephala piceae.

Re : Mollisia albogrisea?
Thanks for the opinion.
I see M. albogrisea was a nom. prov. According to Species Fungorum the current name is apparently Phialocephala piceae.
A bit annoyingly once again a species that seems to be missing from the Finnsh list for whatever reason (all the three names).

Re : Mollisia albogrisea?
However, it is a fairly common species in northern Spain, both at low and high altitude.

Re : Mollisia albogrisea?
I am not really familiar with this species which might occur more often on bark than on wood. And I never saw the brownish 1-septate overmature spores that gave the name Phaeomollisia. And who knows what Mollisia perparvula is?

Re : Mollisia albogrisea?
There's something brown near the basal hyphae in this pic, but I'm not sure what this is. Maybe I'll try to look at the sample a bit more. I wonder where the "piceae" comes from... does this species have something to do with picea or...?

Re : Mollisia albogrisea?
No idea if this belongs to the fungus - but it is possible. When you look in my folder albogrisea (piceae) Phcph KOH+ (Phcph stands for Phialocephala, a name now in use as a genus separate from Mollisia), you can see the protologue (Mollisia piceae, Grünig 2009, CH, on Picea) and reports from US (Mollisia piceae, Tanney et al. 2016, on conifers but also Acer). The anamorph of this species is of the Phialocephala-type, though also single phialides are formed.

Re : Mollisia albogrisea?
Thanks. I'll keep the sample in the fridge for some time and see if there'll develop some overmature spores.
