Hello everybody, on decayed hardwood e.g. Quercus
Peziza -> Phylloscypha labessiana
Margot en Geert Vullings,
21-04-2026 22:14
Diameter 4 cm. No moisture observed upon damage.
Outer surface light brown, slightly rough and white at the attachment. Inner surface light brown. Hymenium:
Cross-section is white, ectal excipulum resembling textura intricata, medullary excipulum with large round cells.
Asci: Measured in water: Me = 358.1 × 12.8 µm Croziers +, J + WTR type.
Paraphyses: Cylindrical with septa and guttules.
Spores: With loose medium-sized warts, not connected, sometimes somewhat closer to the poles. Sometimes with 2 large droplets, but most still developing? Measured in water: (14.7) 14.9 - 16.7 (17.3) × (8.4) 8.7 - 9.9 (10) µm, Q = 1.6 - 1.8
We would like to know which cup fungus this could be?
Thank you very much in advance, Geert & Margot

Re : Peziza
The amyloid reaction of asci is WT type. And the ascospores contain BSG (bipolar spore granules).
These two characters point to Phylloscypha.
I let you identify the species with the key to this genus.

Re : Peziza
Thank you very much for your help.
We do not see the nice round warts of P. labessiana, but sometimes elongated warts; we do not see spores with tapered ends or elliptico-fusoid, so there is some doubt, but we think using the key this could be P. phyllogena?
Kind regards, Geert & Margot

Re : Peziza
I know P. phyllogena with entirely different colours, different spore shape and higher Q value. I can't think of anything other than P. labessiana, although I have no personal experience with it.

Re : Peziza
I agree with Marek, the spore ornamentation of P. phyllogena is different.

Re : Peziza
Thank you very much to both of you; we were hesitant partly because this species does not seem to be known in the Netherlands yet, even when looking at synonyms?
Kind regards, Geert&Margot

Re : Peziza
Bonjour,
je ne remets pas en question l'identification, mais je voyais P. labessiana nettement plus sombre avec des ponctuations sur la face externe rappelant P. boltonii, ayant en tête les photos publiées dans Ascomycetes.org 13 fasc. 3 de 2021.

Re : Peziza
I remembered one very light cup-fungus, which Stano Glejdura determined as P. labessiana...
