Good eveningI have this small (<700 µm diam.) pink-orange Orbilia growing in a herbaceous 9 mm diam. twig (with pentagonal profile on transversal cut).
Asci 8-spores, with the upper line of spores not inverted and the bottom line inverted, inamiloid, (41.0) 42.1 - 57.4 (60.2) x (4.3) 4.4 - 5.4 (5.6) µm; N = 25; Me = 48.3 x 4.8 µm.
Spores fusiform, slightly curved, with a long SB, (12.4) 13.2 - 16.1 (16.9) x (1.2) 1.6 - 2.0 (2.2) µm; Q = (6.3) 7.2 - 9.6 (11.9); N = 51; Me = 14.8 x 1.8 µm; Qe = 8.4.
Paraphysis cylindrical and not very clear.
Ectal excipulum with textura subglobosa-angularis, with a yellow external layer at margin.
Medullar excupulum not sure, but I think textura intricata.
Thank you for your help.

Hi Miguel-Angel
no no, look at the ascus apex: hemispherical and thick-walled. This belongs in subgenus Hemiorbilia and is O. vinosa. But this species was only found on woody substrate so far, with several hundreds of records.
What kind of vegetation do you have there, and what could it be? Pentgaonal could refer to Rubus fruticosus? Actually we had it a few times on that host.

Hi Zotto
Yes, very probably Rubus fruticosus, you are right.
Thanks a lot.

If you tell me the collection data I will take it in the monograph, though we have quite a lot from Spain, see below.
