Hymenoscyphus epiphyllus?
Zuzana Sochorová (Egertová), 22-12-2013 21:44
Zuzana Sochorová (Egertová)Good evening,
could someone give me an advice concerning about my friend´s inoperculate?
Information from her: apothecia yellow-orange, rounded to somewhat ellipsoid. On old grass stems. Czech republic, Giant mountains, 30th September 2013.

Now (when dried) the diameter of the apothecia is 1 - 2 mm, they are brownish and seem to be very shortly stipitate.

Asci 125-143 x 7,5-9 micrometer, 8-spored, with blue inner ring in Lugol. I saw no croziers.
Ascospores 14,5-20 x 4-5 micrometer, smooth, hyaline, with guttules.
Paraphyses 2,5-3 micrometer, septate.

The most similar fungus I found in my sources is Hymenoscyphus epiphyllus. Could it be? Should I add more information?
Thanks, Zuzana

Re : Hymenoscyphus epiphyllus?
Dear Zuzana

I cannot help with dry material. Croziers should be present in epiphyllus and monticola. maybe that a section through the marginal ectal excipulum might clarify between the two possibilities.

Re : Hymenoscyphus epiphyllus?
Thank you, Zotto. For us Hymenoscyphus cf. epiphyllus is sufficient :-)
