Hi Pablo,

looks like a Coniochaeta.

Best wishes,
Gernot

Re : Pyrenomycetes ???

See the genus Coniochaeta.

Re : Pyrenomycetes ???

The most recent key of "well-documented" Coniochatea appears to be "Coniochaeta ershadii, a new species from Iran, and a key to well-documented Coniochaeta species" by Asgare, Zare & Gams (2007) published in Nova Hedwigia 84 (1—2): 175—187.

May be this is helpful.

Re : Pyrenomycetes ???

Hi Palo,

did you compare to more common species, like C. lignaria ?

Alain

Re : Pyrenomycetes ???

Thanks Alain

C. lignaria is very good idea :-)

Regards
