Nimbomollisia (Niptera) eriophori?
Marcus Yeo, 23-08-2022 20:41
This small discomycete was growing on dead leaves of Eriophorum vaginatumin blanket bog at about 550m alt in NW England. Details as follows:

Apothecia sessile; cup-shaped; ca 300 µm diam.; hymenium pale grey; exterior brownish orange.


Excipulum brown textura globulosa.


Paraphyses narrowly cylindrical (2-2.5 µm wide), sometimes swollen at apex; sometimes branched; cylindrical refractive VB in upper part.


Asci clavate; ca 100-110 x 13-16 µm; 8-spored (biseriate); IKI+ blue; with shallow apical ring.


Ascospores fusiform; hyaline; free spores 21-23 x 6 µm; mostly 1-septate, but free spores sometimes 2-septate; scattered small OBs, mainly near ends of spore.


This seems to resemble Nimbomollisia (Niptera) eriophori. I didn't notice gelatinous sheaths on the spores when examining the specimen but the image of spores in the ascus in MLZ seems to show some sort of gelatinous structure at the ends of the spores. Some of the paraphyses have swollen apices but this feature isn't as well developed as I would have expected in Nimbomollisia.


I'd be grateful for a second opinion.


Thanks


Marcus

Re : Nimbomollisia (Niptera) eriophori?
I agree it is. You did not see any living free spores? There the sheath is usually well visible without any staining, also inside living mature asci it is strongly present. It obscures in dead material.

Enrique has nice images (ERD-4532, ERD-6767).

Re : Nimbomollisia (Niptera) eriophori?
Thank you.

There were very few free spores. Spores in the asci were difficult to see clearly (see images) but I couldn't see any obvious caps or sheaths.

Re : Nimbomollisia (Niptera) eriophori?
In the first new image I can actually see them, they are only terminally obvious (broad and thick). The other photo shows dead asci - impossible to see there.

Re : Nimbomollisia (Niptera) eriophori?
Yes I see what you mean! I can just about make out the caps on a couple of the spores in the first image.
