¿Arachopeziza? growing on Apiaceae.
Francisco SÁNCHEZ, 10-08-2017 20:05
Francisco  SÃNCHEZRecolected in Norway. 28.07/17. Ascomas growing on dead stalk of Apiaceae, 0.5-2 mm in diameter, whitish at first, cream color later, with border covered with white hairs.

Ascospores with 1 septum, hyaline, more or less curved. Very broad paraphyses, pointed at the apex. Cylindrical ascospores with pores reactive to IKI.

Re : ¿Arachopeziza? growing on Apiaceae.
I think it is a Trichopeziza of the T. mollissima group. You don't have a pic of the hairs? The septate spores are very probably overmature.

Thank you Hans-Otto, attached photos of the hairs, 2-4 microns wide, tabicate and with obtuse apex. The paraphyses also seem to be tabicated in these new photos.

Re : ¿Arachopeziza? growing on Apiaceae.
Yes, and these contents of paraphyses aren't bad for a Trichopeziza. The genus is still not clarified and difficult to give names. Not sure what you mean with "tabicate".

I mean septate, in the previous photos I did not observe it.
