Calycina?

Buenas noches:
He encontrado estos pequeños apotecios sobre un pequeño sustrato desconocido, tal vez herbaceo.
Tamaño 170-200um de diámetro
Sésiles, de color amarillento palido.
Esporas no septadas. de 7 x 1.7um
Las ascas de 18-22 x 4.7-8um, son IKI +, no sabría decir si tiene croziers o no. No llego a observarlos claramente.
Las paráfisis son cilíndricas (x 1-1.2um), sin contenido refringente, divididas en la base y septadas.
El excipulo ectal con textura prismática y pelos de entre 20-30 x 3-4.5um
Pienso que podría tratarse de una Calycina, pero no soy capaz de identificarla.
¿Que opinais?
Gracias, y saludos

Re : Calycina?
Dear Susana
such short, unstalked asci I cannot imagine in Calycina nor Pezizellaceae as a whole. They rather look like something in the Hyaloscyphaceae, such as Cistella, or perhaps even ?Calloriaceae like Aivenia or Diplonaevia.
You have it still fresh? Paraphysis contents would be important to know in the living state. Your water mounts are too strongly pressed.

Re : Calycina?
This seems paraphyses, but as they are rather unsharp I am uncertain, maybe these are VBs. At least they are too narrow for a Calycina.
The hairs could also conmtain contents, like e.g. in Ciliolarina.

Re : Calycina?
I see. But I am unable to name the genus :-(
