Scutellinia with reticulate pattern

Zuzana Sochorová (Egertová), 05-08-2015 18:10

Hello,
I would like to know your oppinion on this Scutellinia from Abkhazia.
Apothecia 2.5-8.5 mm, vivid orange, rounded or oval, cup-shaped or flat, with long black hairs on the margin.
Spores 16.5-19 x 11-13.5 micrometers (measured without ornament), ellipsoid, hyaline, with a thick reticulate ornament. In some of them one guttule is visible, its diameter is 8.5-9.5 micrometers.
Asci 275-370 x 14-18 micrometers, cylindrical, octosporic, uniseriate, non-amyloid.
Paraphyses 2-3 micrometers broad, with a distinctly broader apex - up to 12 micrometers, septate, straight, simple, with orange pigment.
Hairs 300-1950 micrometers long, 17-25 micrometers in the middle, 18-31 micrometers at the base. Bifurcate to multifurcate, brown, septate, thick-walled (up to 7.5 micrometers wide wall).
Locality: Abkhazia (Great Caucasus), Aapsta river valley, on strongly rotten Fagus wood in a forest, 8. VII. 2015.
I came to Scutellinia pennsylvanica.
Thanks, Zuzana
