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
