Phaeohelotium aff. epiphyllum on moss (First thougt to be Bryoscyphus)

Robin Isaksson, 12-10-2023 20:36

Hi! I wounder if anyone have seen this species before? Or knows it. Found in alpine habitat on racomitrium. Asci is 89-120 x 15-21um with no blue/ red reaction in lugols. Spores 17-25 x 5-7um alive. Spore get 2-3 dots of red reactions in lugols as Roseodiscus formosus. Parafyser with bacteria? Atleast they a moving when alive. In Koh 10 there is a yellowish solution, from the parafyses. Apothecia is Koh negative. Best regards.

ITS AND LSU done.

Re : Bryoscyphus sp on moss

Interesting! Although looking like a Luteodiscus, this must be a Bryoscyphus (Helotiaceae) indeed, judging from the multiguttulate VBs in the paraphyses and excipular cells (they typically move if they have vacuole water enough). No idea of the species. Certainly not B. turbinatus which lacks these VBs etc.

Let me please know the collection date and region. No sharp photo of mature asci?

Best regards,

Robin
