François BartholomeeusenDear forum members,On cow dung, between fruiting b
Last year the fungus presented in 2010:http://www.ascofrance.fr/forum?id=11408
was found again, now in Montenegro on Pinus heldreichii in a subalpine forest by Branislav Peric, with slightly larger spores but otherwise the same. We have now finished an article on it and still could not find anything that fits. Some similarities exist to Odontotrema, but that genus has an amyloid hymenium and lacks a spore sheath. I also see similarities to Exarmidium, but again no spore sheath is known there and the minute apothecia tend to perithecioid and always grow on naked wood, not erumpent from bark.
A sequence from apothecia (ITS, LSU) did not clarify the position of this species, though the closest match was members of Lecanoromycetes (Umbilicaria, Porpidia, Xylographa). For sure, our fungus is not lichenised, but such interrelationships occur perhaps not too rarely.
