Hi to everyoneI would like to know your opinion about these completely superficial and ostiolate perithecia covered by a clypeoid structure that grew isolated on Pteridium aquilinum rachis. The gregarious hemispheric or broadly conical ascomata measure 150-200 microns in diameter, the asci have a sharply cut base and a small Melzer negative apical apparatus and contain eight hyaline, narrowly ellipsoid, mostly 3 septate ascospores. The paraphyses are abundant, some of them capitulate.
With these data I pressume that it could be a fungus in the order Diaporthales, but I do not get any concrete results.
Any help would be welcome
Many thanks again.
I've seen your pictures in Fungi and Lichens of Great Britain and Ireland and I see that they match very well with my collection. I find it very difficult to know many times if a fungus is lichenized.
Many thanks again for your kindly help.
Best wishes
Enrique
Hi Enrique,
I completely agree with Paul. Porina genus was my first idea. Concerning P. aena, I found it on Ruscus, Buxus, Ligustrum, Rubus, Lonicera. Why not on Pteridium. I'm not so surprised.
