David Chapados, 21-06-2025 22:27
David ChapadosHi,

Is this a Calycina? C. herbarum?

Growing on an herbaceous stem (could possibly be mint), Quebec, Canada. 

Spores 12,6-17,5 x 2,2-3,0um.
Asci amyloid, 50,4 x 6,4um.

Re : Calycina?
Hi David!

The contents of the paraphyses are similar to those of Cyathicula.
What do the excipulum cells look like?

Greetings
Ingo

Re : Calycina?
This looks like a great suggestion. I must admit I overlooked the excipulum... I'll have another look and update when it's done. 

Thank you very much!

Re : Calycina?
The excipulum cells are made of parallel hyphae (picture added on iNat).

Is there an accessible key for this genus? I saw that there's one in the work of Carpenter, but can't find it online.

Re : Calycina?
I also suggest Cyathicula. Carpenter's revision of Crocicreas includes numerous species that are today unrelated to Cyathicula or even Helotiales, such as Allophylaria. 

Cyathicula is extremely badly worked out. In my folder are numerous unnamed collections and nom. provs. But I would anyway classify yours as C. cyathoidea in a wider sense, despite the long spores.

The presence of crystals on the outside is typical of many species, but inconsistent.
