Lichenicolous fungus on Myriolecis spec.

We found groups of perithecia on a Lecanora/Myriolecis spec (probably Myriolecis dispersa) and can't find a name for it.
Host lichen was growing on basalt blocks near the waterline of a dyke. Perithecia mainly on the apothecia of the host. Conidia bigutate, ellipsoid sometimes with little deformations, measuring 7,5-8,5 x 3,0-3,5 ?m.
So far I considered the genus Unguiculariopsis, but dismissed it because of the lack of asci.
Does anyone have any suggestions? Thanks in advance.
Kind regards,
Niek and Tom Schrier

Re : Lichenicolous fungus on Myriolecis spec.
Dear Niek and Tom,
Your message is rather misleading. You believed to have an Unguiculariopsis, i.e., you saw lichenicolous apothecia. Then you mention perithecia. Finally conidia. So, did you see three different species, one apothecial, one perithecial and one pycnidial (coelomycetous)? The species shown in the photos is a coelomycete, i.e., an asexual fungus producing conidia within pycnidia. The pycnidial wall and the conidia, especially the guttulation, are typical for Didymocyrtis. You should compare with the known species of this genus, especially those not confined to a single host genus, to get an identification.
Best regards, Paul
