Hello,
today found on attached brnach of apple tree in the field mark.
According to the provisionary key of Claussenomyces by Marson & Baral the nearest I come to is Cl. "caeruleomarginata", but apothecia are very dark.
The spores I have seen have only transverse septae, no longitudinal ones have been observed. Also no tendency to make ascoconidia have been seen.
I first have been thinking of Cl. xylophila, but for this species the spore size is too big, besides other differences.
Not ionomidotic.
I have no idea which Claussenomyces - or am I in the wrong genus?
P.S.: spore measurements x10, means 29,6 x 5,7 µm
thanks for help,
Andreas
vielleicht Durella, in Richtung D. connivens?
Schöne Grüße

Hello Gernot,
thank for this - Durella is a genus I always forget, don't know why ....
And yes it should be Durella connivens, especially as I found in another apothecium spores with 38 and 41 µm length.
best regards and thanks,
Andreas
Hello Zotto,
yes, both fits.
thank you,
Andreas
