Dear Forum,On decorticated wood of Castanea,I foun
Hello all, Lichenicolous fungus on on the thallus of Porpidia tuberculosa.
Small clusters of tiny black apothecia, appearing lecideine with roughened exposed discs and raised margins. Most spores were 2-3 septate, 15-24 x 7-9 µm, epithecium becoming darker green in KoH, paraphyses branched.
Opegrapha (now Phacographa) glaucomaria seems a possibilty and I wondered if anyone might have the key to this group:
Hafellner 2009: Phacothecium resurrected and the new genus Phacographa (Arthoniales) proposed. Bibliotheca Lichenologica 100: 85-121.
With regards,
Jenny
