Very small (~0,5 mm) white ascos, found yesterday
Trichopezizella rubroguttata maybe?

Hello (again :) ),On old stem of Urtica I saw these asco's. Brown hairs with whitish material (at first thought of parasitic fungi). Hymenium whitish, apothecia small: max 0,5 mm.
Asci 8 spored, clavate (but very narrowly so), croziers + , J +. 42-46 x 4,2-5.
Paraphyses exceeding the asci, lanceolate. Spores fusoid, septated when mature, 9-13,2 x 2-2,5.
Considering that it's not growing on wood, not growing on Polygonatum, having asci with croziers and the spore size: could it be T. rubroguttata?
(Must say that to my surprise this species is not known in the Netherlands?)
Thank you (again :) )!

Re : Trichopezizella rubroguttata maybe?
Hello
a closeup of the hairs would be good, but in any case I see that the hairs near the base are undulating, very typical of Lasiobelonium. On dicots occurs L. nazarovae, for which I used for a long time the possibly wrong name L. lanceolatum. Maybe this genus is not easy and the limits to the wood-inhabiting L. variegatum are not clear-cut. There exist also collections on grasses.

Thanks for your answer Zotto, I will then keep it open!
Alas :), but that's what it is! Learned a lot again anyway!
Kind regards, Maria
