Mollisia
Zuzana Sochorová (Egertová), 24-07-2022 14:01
Zuzana Sochorová (Egertová)Hello,
yesterday I collected this Mollisia.
Ascospores (10.3)10.9-12.9(13) × 2.4-2.8 (3) µm, Me = 11.7 × 2.6 µm
Q = 3.9-5.2; Qe = 4.5
OCl = 2 (several tiny drops), no septate spores observed neither in asci nor outside them

Asci H+, bb, 75-89 × 5.8- 6.6 µm

Subhymenium built if hyaline hyphae.

Cells of the ectal excipulum brownish up to the margin.

No yellow reaction in KOH, the section only becomes lighter.

Locality: Czech Republic, Moravia, 250 m a.s.l., on thin twigs found in the grassland (only broadleaved trees grow nearby)

Using the key by Andreas, Mollisia melaleuca seems to be the best option - but the spores are a bit slimmer than given in the key, and hymenium is not white...
How would you identify this find?
Thank you, Zuzana

Re : Mollisia
You have a sequence for this? :-)

Earlier I would have identified this as M. benesuada,e.g. for HB 3936a and numerous pother samples,  but then I learned that M. benesuada is a species growing on bark (Ingo called it also alni-corticis).

Especially Ingo's sequenced samples suggest that this is either M. oblonga or M. nodosa, which can only be differentiated by DNA (or by their anamorph).

M. melaleuca could be a species with an OCI of 0, e.g. IW033 in our melaleuca folder. However, Torsten's M. melaleuca 18.VI.2011 has spores like yours and who knows what it is.

Re : Mollisia
Thank you, Zotto. I felt already in the field that I should better pretend I didn' t see it ???? The key gives OCl = 2 for M. melaleuca. And for M. benesuada is given that brown cells should be located only at the base od apothecium...
I don't have a sequence of this.

Re : Mollisia
Yes, M. benesuada is rather light-coloured due to pale excipulum.

Re : Mollisia
But I would say that in my sample brown cells are located not only at the base - they reach almost the margin (it should be visible in picture "12 of 15" - the section).
Therefore, I jumped to 25b in the key.
(25a Cells of the ect. exc. only at the apo. base brownish (apo. adhered ± punctiform ) ....... 26
25b Cells of the ect. exc. +/- up to the margin brownish coloured ......................................... 28)
Difficult genus for me...

Re : Mollisia
Surely yours is not benesuada (alni-corticis). But as far as I know Andreas does not have oblonga and nodosa in his key, I remember Ingo saying that he even thought this to be American species as they have their types there.
