Bernard CLESSEBonsoir à toutes et tous,Pourriez-vous m'aider à
This small black soft 800-1.200 µm diam. was growing probably on Urtica dioica, at semi-alpine place in a snowfield (nevero). It is young and more or less dead, but I think enough live to identify it.
Hemiamyloid asci, with croziers, elipsoid-cylindrical spores of (9.8) 11.1 - 14.1 (17.1) x (2.8) 3.4 - 4.0 (4.6) µm; Q = (2.8) 2.9 - 3.9 (5.1) ; N = 37; Me = 12.6 x 3.7 µm ; Qe = 3.4
Ectal excipulum brown with textura angularis and hard. Medular excipulum gelatinized and very soft.
Conidial presence.
Thank you in advance for your opinion.
Miguel Á. Ribes
did you test the Leuchtmann key?
Zotto
Yes, I have check it and I think is the nearest species, but it is the first time I study an Heterosphaeria.
Thank you.
Miguel Á. Ribes
If so, following Leuchtmann key I arrive H. lojkae, because H. patella has not that bristle-like hyphae, or am I making a bad translation?
Thanks
Attached more macro photos. All of them were closed and depressed on the top, none opened.
Any posibility about H. patella has that bristle-like hyphae? Otherwise, I am at a dead end.
Thanks again.
P.D. Have you see the ladder-like perforations of the "Alnus" wood in "Another Mollisia ¿perelegans?" post
5 days later "incubating" the sample in a wet location, only small changes are observed, perhaps a little more star-shaped open apothecia, but nothing similar to Zotto's pictures.
Thank you.
Thanks.
recogi el dia 30-05-15 esta muestra que es la misma que la tuya, Heterosphaeria patella.
despues de quince dias en la nevera y en camara humeda han abierto todos.
Los recogi en tallos de Angelica sylvestris, completamente secos, y al sol, habia cientos,
los tallos que estaban en sombra o algo humedos, no tenian ninguno,
supongo que quiere insolacion para poder fructificar,
Un saludo
Rafael
Suerte.
Miguel-Angel: Your pics from last year show dead elements. It was obviously in bad state, for whatever reason. Although i expect that dead apothecia do open similar as living ones, this might be the reason why you were unable to ripen them more properly.
Zotto
I hope this species will be found again in the living status this year.
Best wishes
The conidia with the whip-like appendages belong to the sclerotia-like anamorph of Ceriospora polygonaceanum.
Best regards
