White Scutellinia??

Hola a todos.


Subo unas fotos de unos apotecios que encontramos el sábado pasado, sobre madera medio sumergida en un arroyo de montaña, a unos 1.500 metros de altitud.


Esporas multigutuladas de 18,5-20,5 x 12-13 micras, ornamentadas con verrugas alargadas o pequeñas estrías.


Paráfisis sin color en su interior.


Pelos de hasta 1.450 micras de longitud, de base multi-furcata.


Pensé en alguna forma blanca de Scutellinia, qué les parece?


Gracias por su ayuda.


Rubén

Hi Ruben,

this looks like Trichophaeopsis bicuspis. I did not check weather the microscophy fits...

Re : White Scutellinia??
Hello Rubén,

interesting collection. On the first photo I see (or want to see) some orange-ish tone in hymenium, not purely white. Also the hairs and spores look IMHO better for albinotic Scutellinia than, say, Paratrichophaea. I'd consider something from the S. crinita group, perhaps even crinita, as the ornamentation is rather low and the hairs too look macroscopically like this species (palisade of short hairs and among them much longer hairs, evenly spaced). What is the Q ratio of spores?

Re : White Scutellinia??
I would agree with Viktorie that is looks more like an albino form of S crinita.

Re : White Scutellinia??
Beautiful. And I agree this is a Scutellinia species that missed to synthesize its carotenoid pigments :)
