Scutellinioid in very damp woodland, large-spored - Denmark

Spores ellipsoid with flat, low warts. Paraphyses flame-shaped. Spores ca 32,5 x 14 µm, with loosening wall. With short, scattered, brown, rooting, basally divided hairs.
And merry Christmas and Happy New Year

Re : Scutellinioid in very damp woodland, large-spored - Denmark
Hello,
size 32.5 × 14 would make a Q = 2.3, that's certainly not the case here. If it in fact is 22.5 × 14 (Q = 1.6) than I would search around S. umbrarum. S. parvispora has much smaller spores, S. pseudoumbrorum smaller ornamentation, perhaps the short-haired S. ahmadii could be considered (but the ornamentation should be higher, but Schumacher noted the frequent presence of abortive spores as a typical character of ahmadii, which might be the case here, too), ... Do you have any photo of the ornam. in LACB?

Hello Thomas
As Viktorie says the only species with spores with these dimentions is S macrospora but your photos do not show spores of this shape which should be much more narrowly ellipsoid. I also don't think they should be more broadly ellipsoid for umbrorum.
You say the spore wall loosens, was this with LCB? Spore ornamentation with LCB would also help.

thanks, Malcolm
But is it a genuine Scutellinia?
cheers

As far as I can see yes it is.
