Tricladium varicosporioides on indet. decorticate
Dear Forum,
Sunday I found an old Nemania serpens with some small cream-coloured apothecia on it.
They had clavate hairs(19-25x6µ) with blunt tuberculate warts. No KOH reaction.
Asci measured 26-43x5.5µ and had croziers. Spores were hyaline and biguttulate(4.3-4.8x2.2µ);
Cistellina stereicola seems to be close but is associated with Stereum instead of Nemania.
Any idea?

Thank you for your answer Zotto.
Do you think geelmuydenii is still possible although IKI only gives a mild blue coloration of the upper part of the apical apparatus. I used IKI several times but no hemiamyloidity was seen.
Marc
Good morning Zotto,
I used both Melzer and Lugol after pretreatment with KOH. In Melzer a had a minimal blue coloration, in Lugol the blue was more pronounced.
I cannot tell you what the concentrations are but both products came from mykoshop.
Marc
It is clearly a very difficult group.
Thanks for your answers
