Sporormiella?
Bernard Declercq, 18-10-2010 20:40
Bernard DeclercqHello,
I recently collected a pyrenomycete on very decayed wood of Quercus robur, with immersed to semi-immersed subglobose ascomata 0,35-0,5 mm diam., non-papillate, with a central pore, rugulose, black. Asci are bitunicate, cylindrical, 2-spored (!), 68-77x7-8 µm. Spores are cylindrical, smooth, dark grey, oblique 3-septate, rarely 2- or 4-septate, constricted at the septa, (12,5)17-19,5(20)x5,5-6µm, no germ slits observed nor gelatinous coating, with two large guttule and many small ones per cell.
Such spores are Sporormiella-like, but lignicolous species are rare in this genus. Any idea?
Herewith a photo of the asci.

Thanks in advance,
Bernard

Re:Sporormiella?
Bernard,
asci on your photo are unitunicate, they have a discoid apical ring and ascospores lack germ slits, therefore it cannot be a Sporomiella.
Your fungus likely belongs to Synaptospora Cain, in which one-celled ascospores are stuck in groups of 2-3-4 within the ascus.
Characters of the peridium and ascospores are needed to attempt an identification.
Cheers,
Jacques

Re:Sporormiella?
Merci Jacques pour cette indication intéressante. Avec les ascomes à verrues et des spores de 6,5-8,5x5-5,7 µm, me basant sur la clef de Reblova (2002), j'arrive à Synaptospora petrakii Cain, espèce décrite sur Betula au Canada. Est-ce que l'espèce a été déjà trouvée en Europe?
