Zuzana Sochorová (Egertová), 25-06-2022 21:26
Zuzana Sochorová (Egertová)Hi forum,
are there any doubts this is Orbilia auricolor?
Apothecia pale orange, sessile, without hairs or glassy processes, up to 2 mm in diameter.
Ascospores 7.7-10 × 1-1.3 µm, curved, tapered at one pole. SBs globose or tear-shaped, 0.8-1.4 × 0.6-0.9 µm.
Conidia 1-septate, 15.5-19.2 × 5.5-6.2 µm.
Asci 8-spored, up to 46 × 3.9 µm, base T- or H-shaped, apex truncate.
Paraphyses capitate, terminal cell 20-30 × 2.5-4.2 µm.
On a twig of a broadleaved tree, Moravia.
Thank you, Zuzana

Re : Orbilia auricolor
Hi Zuzana

you have no macro?

The apos are very typical, but only with the anamorph the species can be tried to identify.

The conidia remind us of O. cladodes, but they are narrower than usual. Drechlser's cladodes has conidia *(11-)13-16.5(-18) x (6.2-)7-8(-8.8) µm. Did you see the conidiophores?

Re : Orbilia auricolor
Hi Zotto,
I took photos of apothecia, but they are at a card which is inside a camera Michal took with him for an excursion this weekend. I will show them tomorrow.
I can see conidiophores, although mostly without conidia - they release when I put the cover glass on the mount.

Re : Orbilia auricolor
Ah, then it is clear with the conidia. This would be interesting to culture and see if the conidia in culture come out just as those on the substrate. Finally, a sequence would clarify the identity.

Re : Orbilia auricolor
The collection consists of only two apothecia, here is a photo of one of them. Anamorph is present as well. But maybe we could try to sequence it.
