Asco on Lichen
Javier Etayo, 16-05-2010 11:07
Do you have any idea about this ascomycete? It grows on a lichen in an Ecuador mountain. It seems to Rosselliniella (Xylariales) in some aspects, but all lichenicolous are with 0-1(-2) septate spores and without such a subiculum.
Perithecia with long, brown, septate hairs, sessile on a subiculum of many brown hyphae on Hypotrachyna (lichen) in tropical mountains. No paraphyses. Hymenium KI+ blue around asci. Asci long, 8-spored. Ascospores 7-8 septate, brown, 50-60 x 13-18 µm.
