Pezizella on Dryopteris
M. M. Gotink, 30-05-2013 20:08
A fews days ago I found this Pezizella on dead petioles of Dryopteris, probably Dryopteris dilatata.

The apothecia are up to 1 mm in diameter, short haired on the outside and short stalked.


Asci 8-spored.


Spores 8-11 x 2 µm, with some small guttules on both ends.


There are 2 Pezizella's on ferns I can find, P. campanulaeformis and P. chryostigma. But my measured spore size is in between both of them.


Does someone have an idea what species this could be?

Re : Pezizella on Dryopteris
Spores vary in chrysostigmum between 5-6 and 7-9 µm. 11 µm seems rather extraordinary. Typically, the apothecia turn yellow on bruising.

The identity of campanulaeformis is unclear to me.
