Dothideomycete on Pinus
Stefan Blaser, 30-11-2019 08:06
Dear all,

I need help with this one:


Substrate: On a decorticated branch of Pinus


Macro : Ascomata unilocular, about 0.5 mm in diameter, black, smooth, with a simple pore opening at the top. Substrate around ascomata bleached white. Hymenium in loculi pinkish-transparent.


Micro : Asci 125-145 x 17-21.5 µm, bitunicate. Pseudoaraphyses cylindrical, about 2-2.5 µm, simple or with short side branches. Spores constantly four-celled, slightly constricted at the septa, nearly hyaline (mature spores may be seen as very slightly colored), 26.5-32 x 8.5-12 µm.


Thanks a lot for any suggestions,


Stefan
