Bernard DeclercqHi,
I recently collected a discomycete on Hieracium umbellatum with following characteristics:
Apothecia gregarious, disk-shaped, sessile, disk plano-convex, 0,4-0,65 mm diam.; hymenium olivaceous yellow to olivaceous grey-brown; in strong contrast to the receptacle which is blackish brown up to the smooth margin. Asci cyl.-clav., 8-sp., sp. 2-ser., porus IKI-, 94x8-9 µm, arising from croziers. Spores fusiform, straight to slightly curved or inequilateral, with narrowlyu rounded ends, smooth, hyaline, aseptate, 15,5-18x2,5-4 µm, with two large and many small LB's, LC=4-4,5.
Paraphyses slender, base 1,5-2 µm diam., septate; apices capitate and 5,5-7 µm diam., forming an epithecium, covered by brown gel. Ectal excipulum of hyaline gelatinised textura prismatica in a +/-45° angle to the surface, end cells covered by brown gel.
Any idea what this could be?

Best regards,
Bernard Declercq

Hi Stip,

Many thanks.
The species is probably new for my country.
