Orbilia sp.
Nicolas VAN VOOREN, 19-05-2009 23:54
Nicolas VAN VOORENUn Orbilia récolté sur branche morte de Salix, encore en place (h = 1,80 m), me pose problème. Ci-joint la fiche.

Petite description (in english): asci moderately truncate at apex, 8-spored, 22-34 x 3-5 µm. Paraphyses cylindrical, with a thin and few abundant glassy process, Ø 2,5-3 µm. Spores ovoid, with a rounded SB affixed to the wall by a small connection (difficult to see).

J'ai cherché dans la section Ovoidea mais rien ne semble parfaitement coller. Une idée ? Une direction ?

Re:Orbilia sp.
Hi Nicolas

nice find! I presume you have Orbilia cejpi, according to my key. This is a medium rare species, usually found on the ground on various substrates, but sometimes also air-protruding. You should verify that there are no glassy processes at the margin, and also the anamorph would help. Sometimes conidia can be found around the apothecia. They are of the Dicranidion type (tune-fork-shaped) in the case of cejpi and the close O. coccinella. There is also an O. liliputiana which is from Macaronesia on Pinus wood, and this has unbranched conidia.

Do you have macrophotos?

Hi Zotto.
Thank you for your answer. I don't have any macrophoto but I can send the collection to you.

Re:Orbilia sp.
Hi Nicholas

I think this would be a good idea. We have not very often seen this O. cejpi. Was it a marshy place, shady or sunny?

Thanks in advance!

Package sent!

Location of the collection: Mervent (Vendée, France), near the "Pont du Diet", along the river "Mère" (0° 46' 26" O, 48° 32' 01" N). This place is "sunny".

Re:Orbilia sp.
Hi Nicholas

Now, I have examined 3 of the perhaps 15 or more apothecia, and I always find strongy curved spores! What I see is O. "fabacearum", a not frequent species with spores resembling O. delicatula, but smooth and with the SB in the middle area (dorsal face). It seems we should rename this species, it is the second time on Salix, and it was also once on a conifer.

I will examine more, but I examined also two apos which were only half, so should be those you tested. Did you send me the complete material? We will try a culture because the presumed anamorph is interesting but not sure.
