Hello everyone, On dead wood of Cytisus scoparius
I have a black Pyrenomycete growing in small clusters in cracks of bark of small Larix twigs. I hope to get some help on this.
Description: Perithecia in dense groups of 3-8, globose or more often elongated, black and glabrous. Size about 0.3-0.5 mm.
Asci often difformed and very strongly saccate. About 80-100 x 15-35! (40!)micros. Polysporous (>64 at least). Spores 7-10(-11) x 1.5-2 micros, allantoid, hyaline (or slightly yellowish/greenish) and usually with an inconspicuous septum.
I found Nitschkia broomeiana (Fracchiaea b.) to be quite similar microscopically, but the Perithecia should be spiny in this Species.
I'm grateful for any help/comments
Stefan
perhaps Coronophora.

Martin
this one should be Coronophora gregaria. It is quite similar to my findings shown on FP.

Ja, es sieht sehr gut aus für C. gregaria. Suche noch nach einer Beschreibung der Art.
@Björn: Hast du eigentlich die Funddaten und den Artikel gekriegt?
