Buckwheat PeteHello, I'd like to ask about this older specimen:
Bonjour à tous,Enfin un peu de temps pour trier mes photos et observations de 2015. Ici, du congrès de la FAMM.
Deux récoltes sur Helleborus foetidus
1- Hyphomycète: Colonies blanches, à la face inférieure de feuilles vivantes.
Conidies hyalines, elliptiques ou allongées, parfois en chaînes, 10-18 x 2.5-3.2 µ.
Pas d'idée.
Spores + ou - allantoïdes, hyalines, huile=2, 7-10 x 2.2-3 µ.
Asques 8-sp, croziers -, IKI BB, 41-48 x 7.5-8 µ.
Paraphyses au sommet un peu réfringent, x 2.5-3.2 µ
Excip. ectal text. ang./glob.
Rien trouvé.
Amitiés - LUC.
The disco is easy: it is
Calloria rubicunda Sacc. & Speg. (= Pezizella rozei (Quél.) Sacc., ?= Hyalinia helleboricola Ade)
specific to Helleborus leaves.
my guess was that it belongs in Psilachnum, but in the meantime I am a bit sceptical. If you have kept this sample in your herbarium it would be worth a try to get a sequence. Maybe someone wants to do this.
