Also Orbilia on salix bark :)
Maria Plekkenpol, 19-05-2020 11:33
Maria PlekkenpolHello, I just read the post from 18-05-2020 and I wanted to post a topic too. Seeing the last post (what a coincidence by the way!!!)  I'm almost sure, but because it's very rare in Holland I would still very much appreciate a reaction/confirmation.... :). I placed pieces of bark from Salix caprea in a moist chamber and these Orbilia's appeared. Apothecia max 1,2 mm, sessile, smooth. Colour light apricot. Excipulum textura angularis.

Asci: 40-55(60) x 3-5, often truncate. 8 spored, with slim tapering end, base often "forked"(bifurcate?). Paraphyses more or less same height, apex hardly swollen with "topping" (I don't know the word.... exudat?).


Spores 12,5-14,5 x 1-1,7. slightly curved. SB's large, up to 1/3 of the spore (app 3-4 µ). Reading "Phylogenetic and morphological circumscription of the Orbilia aurantiorubra group" and an article written by L. Rommelaars (Coolia 2013) I think this is also Orbilia aurantiorubra?

Hi Maria

yes it must be. Lucien's article I do not know, I only have the helotialean one in Coolia from that year. It is probably the only sample from NL of which I know (from Kaaistoep).

But be cautious and look at the paraphyses. A similar species has lageniform paraphyses and is more yellow.

Thank you very much Zotto!! I am very happy with this one. Just to be sure I add a picture of the paraphyses, they are not lageniform I think... ?

Indeed, they are uninflated or slightly clavate or a bit spathulate. In O. xanthoguttulata they are filled with yellow oil drops.
