Calycellina?

Enrique RubioHello my friends


I present you a new problem with these small (up to 1 mm), white, stipitate, gelatinous, 'cyathiculoid' ascomata that grows on Fagus (Betula?) wood close to the river at 1500 m.

The long, fusiform, not septate, multiguttulate ascospores are very peculiar at least for me.
The asci have an apical broad pore that I think is of Calycellina-type (?), reddish at low concentrations of IKI and very blue at higher. They seems to have not croziers and they are 8-spored. Paraphyses and marginal cells have conspicuous Vb's as the subhymenium too.

Excipulum of textura porrecta.

I think could be a Calycellina species but I'd like to know your opinion.
Many thanks again
Enrique

Re : Calycellina?
Allophylaria?
Debería ser rojo a mayor concentración de IKI y azul a menor.
Un abrazo,
Raúl

Re : Calycellina?
Hi Enrique, 
The shape and other characters of your find make me think about a Allophylaria . I am used to byssacea on Lycopus stems but here on wood, may be macrospora ?

Amitiés et congratulations to you too !!! 
Michel

Re : Calycellina?
Sí, en la Biblia (Zotto´s DVD) viene sin croziers y las medidas esporales, etc. coinciden.
¡Saludos a Michel también!

Re : Calycellina?
Thank you my friends. Allophylaria seems to be a good genus for my finding. I did not know that Allophylaria can to grow on woody sustrates too...
Raul, the ascus image on the right is made at low concentrations of IKI (reddish reaction). Later I added some crystals of Iodine to my IKI (probably too much!) and the ascus reaction (left) is vivid blue.



La primera semana de octubre van a venir Brigitte, Michel y Nicolas a Somiedo. También va a acudir Miguel Ribes. ¿Por qué no te animas a acompañarnos?

Re : Calycellina?
Maybe it´s a variable character in this species. In HB 7056 Zotto indicates that Lothar obtained a red reaction ("LK rot!"). But ,for the very same ascus, it should be always first blue and after red at higher iodine concentration in an hemiamyloid species.

Muchas gracias por la oferta Enrique, pero entre la jefa y el jefecillo (y aparte el curro), no me puedo escapar una semana. Con más tiempo igual un fin de semana... pero para ese me viene muy corrido. Pasarlo muy bien, ¡veo que estarás bien acompañado!

Un abrazo,
Raúl
