Pyreno on the sporophyte

Enrique Rubio, 17-03-2017 21:06

HI again
Blackish, not setose pseudothecia up to 0.2 mm in diameter are found subepidermial on the setae of the sporophytes of dead moss Ceratodon purpureus. The greenish smooth, dimorphic ascospores are < 20 microns long and the asci are bitunicate. I feel this a meber of the family Venturiaceae, maybe in the genus Lizonia or Venturia.
Have you some idea?
Thanks again

Re : Pyreno on the sporophyte

Hi Enrique,

Yes it's a Lizonia species.

Which one ?... Not so easy, as usual.
