Re : Incrucipulum sp

No Incrucipulum. I have presently no clear idea, but the species should be sought in Albotricha or Dasyscyphella.

Ah, D. claviculata grows on Quercus leaves. It has crystals among the hairs, and I see one crystal at the upper right of your right photo.

Re : Incrucipulum sp

Hola Leandro

Mira a ver si te encaja en Dasyscyphella claviculata.

Un abrazo,
Raúl

Re : Incrucipulum sp

I have also another idea: Capitotricha patula (Lachnum patulum). The somewhat thick-walled hairs, broad and long paraphyses, and pale orange hymenium would point to this.

Leandro Sánchez, 30-04-2014 18:40

Re : Incrucipulum sp

Has long parafisis and some crystals in the hairs

Hans-Otto Baral, 30-04-2014 20:56

Re : Incrucipulum sp

Have you measured the hair length?

In D. claviculata they are 80-100 µm , thin-walled also in lower part

in C. patula 100-200 µm, below with about 1 µm thick wall.

Leandro Sánchez, 30-04-2014 22:49

Re : Incrucipulum sp

Yes, I have measured 4 hairs
61-3 µ
92-4 µ
117-4 µ
121-4 µ
and 1,2 µm thick wall

Re : Incrucipulum sp

Thank you Zotto
Gracias Raúl.

Re : Incrucipulum sp

oh, this is not easy. But I tend at the moment to believe it is Capitotricha patula.

Michel Hairaud, 26-06-2014 15:05

Re : Incrucipulum sp

Hi Zotto,

By the way, is the combination C. patula yet published ?

I can see in lit. and various dtabases the name Capitotricha patula (Pers.) Järv & Baral ined

Hans-Otto Baral, 26-06-2014 16:51

Re : Incrucipulum sp

THis is right. Not validly published yet. But this is a big problem: I studied authentic material of patula in Leiden in 2005 and it was Incrucipulum ciliare! (H B 7701)

Re : Incrucipulum sp

Ha !

Merci cher Zotto
