A blackish Lachnaceae with yellow hairs
Kosonen Timo, 13-10-2015 13:55
Kosonen TimoBonjour,

This handsome +- immature Lachnaceae (right?) grew on a fallen decorticated Populus tremula log in SW Finland. There are some asci, spores measure around 10 x 2,5 um, but it was collected clearly immature and asci are still sparse after almost 14 days of incubation in fridge.

Hairs, or crystals on them, are yellow, and they (and the content inside the hairs) turn blue in Lugol. In Melzer's hairs/excipulum where unchanged or then somewhat dextrinoid/amyloid -or then it's just the contrast (an artefact). Ascal pore reaction not observed. Paraphyses are not clearly lanceolate nor are they definitely blunt.

With this, I should have a genus atleast, but I haven't really dug into Lachnaceae yet. Where should I start? Mind the blurry pictures.

Hello
I am quite sure it is Neodasyscypha cerina.

Ah, of course! There's a plenty of N. cerina on Populus bark... should have made the connection...

thanks,
