Pyrenochaeta nobilis var. ilicis

Hello forum,

On a dead leaf of Ilex aquifolium, covered with Ilicina Trochilia, I found a hairy, small perithecium.
I think it is: Pyrenochaeta nobilis var. Ilicis


FRB: diameter 280 µm;
Hair: 355 x 8.5 µm multiple septa;
Conidia: cylindrical 6.02-8.29 x 1.36-2.05 µm.


I have no literature on this fungus except Ellis and Ellis.
Can I ask two questions:


1) does anyone have more info on this species;
2) when making my preparation I saw a cloud of small, globose to ellipsoid "conidia" (see White arrows) emerging:
3,64-4.69 x 2.52-3.21 µm. Is there a relationship with this Pyrenochaeta?

Best regards


François Bartholomeeusen

Pyrenochaeta ilicis is described in Volume 1 of British Stem and Leaf Fungi by W.B. Grove.
