Hola, me gustaria conocer opiniones sobre este tem
It was growing on dead monocotyledonous leaves (Phragmites australis or Cladium mariscus) in lowland fen.
Apothecia are white, short-stalked, <0.5 mm diameter.
Excipulum is of thin-walled cells. Marginal cells are ca 20 µm, with oil-filled contents.
Asci 45-60 x 4-5 µm. Not sure whether croziers are present or not. Reaction of ascus tip in IKI is ambiguous – apparently red in some cases, but seemed to be blue in others.
Paraphyses are ca 2 µm wide, with oil-filled contents.
Spores (7-)8-10 x 1.5 µm, with a few small oil bodies.
Am I correct in identifying this as C. cruentata? Thanks in advance for help.
Marcus
The blue IKI reaction appears at low concentration, the red at higher.
