Discomycete from old polypore Gloeophyllum abietinum
Alex Akulov, 21-09-2010 12:46
Alex AkulovDear Colleagues.
Please advise, what could be the mysterious sample of discomycete from Carpathians (Ukraine). Ascomata formed on the old fruit body of polypore Gloeophyllum abietinum on fallen Picea abies trunk. Apothecia are small, gregarious, yellowish-orange, slightly immature. Asci, lanceolate, about 100 x 6,3 microns. Paraphyses are very numerous, filiform, uniform width of about 1,5 microns, branched at the base. Ascospores are one-celled, oval or fusiform, with one large and several smaller guttules inside.
I suppose that in mature specimens the size of asci and spores may be somewhat larger.

I would be very glad for any ideas.
Waiting for answers,
Alex

In Lugol paraphyses quickly acquire color of iodine, their tops are slightly amyloid.
Asci with amyloid apical ring.

Well this needs some microphotos and a spore size. Could be a Hymenoscyphus (Phaeohelotium).
