Observation 69918: Pyropyxis rubra (Peck) Egger

Not so sure about the Id.
These pretty cups carpeted large areas of burnt birch and aspen forest (with some young Pinus sibirica). The cups were mostly within 4-8 mm in diameter, some reaching 12 mm and more.
I’ve never seen anything like that so I’d be very grateful for a confirmation of the identification or for other versions.

Based on microscopic features: Nina Filippova grew a conidial state in a Petri dish and it matches P. rubra. So do some microscopic features (e.g. short hairs on the sterile surface which give fruitbodies the velvety look).

It is always a joy to see “Discomycetes” well documented here. Looking forward to more.

It’s Pyropyxis rubra after all…

… but this summer we found the real Rhodotarzetta rosea – I’ll post it later. These two species are amazingly similar and even seem to be equally finicky in their habitat preferences (stenotopic, that is).
