Durella related?
Adam Polhorský, 22-04-2016 18:11
Hello,

size 0,3-0,8mm , gregarious on a quercus branch.

Spores: (6)7-9(9,5) x 1,5-2µm, with one spetum, oil content variable- usually 2 big gutules at poles with some scattered smaller ones.
Asci: inamyloid, 8-spored, no croziers observed
Paraphyses: straight, hyaline, no content observed, with brown crust on top of hymenium

Searched in Patellariales, Durella species- think i´m in a wrong  genus, can someone help?
Thanks,
Adam

Re : Durella related?
Hi Adam

this requires some further tests. I imagine it is what i call Durella uncinata, but it is unrelated to Durella, possibly a Skyttea.
I am quite sure if you add KOH a purple dye will extrude.

But the asci should be with croziers and the paraphyses hooked. Both I cannot see on your pics.

Re : Durella related?
You were right Zotto! I should´ve been more thorough. Croziers are indeed present, and paraphyses are distinctively hooked. Sorry, i dont have good enough pictures to show .
But the hymenium stained  dark red-purplish and no exudate seen - 3 and 10%KOH was used. Do u have any photos- so i know what reaction im looking for? I didnt find the species in your drive under Durella group.

Thank you very much, as always.

Re : Durella related?
Indeed I moved it to Cordieritidaceae where Skyttea belongs.

You find it here:
https://drive.google.com/folderview?id=0B5SeyOEkxxZhMFJLcDd5YlB1RFE&usp=drive_web&tid=0B5SeyOEkxxZhYVZub0N1aGY5YTg
In this folder you can see a ionomiditic reaction, though a bit indistinct.

In the subfolder uncinata you see most below a pic with nice reaction.

This dissolution of pigent is transient, i.e. when you squash in KOH you see nothing, you must pit it in water and then add KOH to the edge.
