I found this species in Quebec, Canada, on herbace
Hello, I am new here and also a beginner. So I know very very little, but am eager to learn. Last Sunday I was near a pool on loam soil. On a little piece of leaf I saw these, I will decribe what I could find (some things I couldn't find due to lack of experience). Ectal ? excipulum textura oblita/porrecta, asci 120-130 µm x 11-13 µm. Paraphyses a bit longer, filled with VB's (they disappeared rapidly with KOH), curvy and branched (not all), about 2 µm broad. Spores 3 times septated (already in the asci), 25-32 µm x 3,5-4,5 µm. Could this be Crocicreas culmicola and is that the current name? And feel free please to tell me if I didn't do something or did it wrong. Thank you!
Hi Maria, welcome to Ascofrance !
The characters you present do match this species , including the Hymenoscyphus type reaction in IKI, which leads to the preferred combination in Cyathicula .
Di you remember the kind of leaf as substrate ? I am used to collect it rather on poaceae.
Amitiés

In Cyathicula (including culmicola) the reaction in IKI is similar to those in Hymenoscyphus : two parallel lines . In Crocicreas the reaction is enlarged at the top as in Calycina
Here are the three main types designed by H. O. Baral (Zotto) and you will see more on his site https://in-vivo-veritas.de/
