Pyrenomycete from coniferous wood
Björn Nordén, 19-05-2011 20:13
I have this nice pyrenomycete with aggregted black ostioles and immersed perithecia in rounded-oblong aggregations) from Picea (Pinus?) wood. Asci cylindrical, twin-walled, lacks apical apparatus, inamyloid, p. sp. 40-50 x 4-5 mym, not floating like in Diaporthe. Ascospores 8 per obliquely uniseriate, 7-8 x 2-3 mym, cylindrica, two-celled with central septum, rounded ends, greyish, with 2 small oil drops. Paraphyses simple, longer than asci, ca 1,5 mym broad. Peridium medium brown, of rounded cells ca 4 mym in diameter.

Yes, perhaps a drawing or a photo would talk better to us. It seems to be interesting.
