polysporous perithecia
Stefan Blaser, 22-03-2013 09:55
Hello everybody

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

Hi Stefan,

perhaps Coronophora.

Re : polysporous perithecia
Hi Stefan,

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

Re : polysporous perithecia
Danke Martin und Björn

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?
