Hyalorbilia?

Hola,
He recogido estos apotecios en un tallo de Sambucus ebulus. Crecían en grupo. El tamaño entre 130-180um.
Las ascas son cortas, con croziers. Las esporas son muy pequeñas.
Varios apotecios llevavan asociado el anamorfo que muestro y en todos había esas celulas globosas que tambien muestro en las imagenes.
He supuesto que se trata de una Hyalorbilia, pero no la identifico. Agradecería vuestra ayuda.
Saludos
Susana

Re : Hyalorbilia?
Hmm, this looks like a Hyalorbilia indeed, but since there are no living elements this is difficult to decide. The anamorph, in any case, cannot belong to Hyalorbilia because its conidiogenesis is phialidic.
You cannot try a water mount in which the spores are even the asci and paraphyses are alive?

Re : Hyalorbilia?
Hola Zotto,
He hecho varias preparaciones pero en ninguna he conseguido ver ni paráfisis ni esporas vivas.
Otra vez será.
Muchas gracias,
Susana

Re : Hyalorbilia?
I cannot remember that name, but it might have stood for what now is H. multiguttulata. This is astonishing, so we must conclude that your sample was a mixtum of two species. The other perhaps something like H. latispora. In any case, both would be unusual species.
I am sure this H. multiguttulata was another apothecium?

Re : Hyalorbilia?
Hyalorbilia has a gelatinized hymenium, so the elements (asci, sometimes also spores) often cannot be separated but lose turgor due to pressure.
I am now surprized: Your last two pics show long and narrow spores reminiscent of a third species, H. juliae! How many apos did you test now? The first of the four is multiguttulata according to the added spore. The second was perhaps also H. juliae.

Re : Hyalorbilia?
La foto 1, es un apotecio de H.multigutulata
Las fotos 2,3 y 4 corresponden a un único apotecio de Hyalorbilia, posiblemente juliae

Can you perhap ssay which was the smaller more white and which the larger more yellow?

Re : Hyalorbilia?
Como no tenía claro quien era quien, he vuelto a mirar al microscopio nuevos apotecios y esto es lo que he podido comprobar y en las imagenes queda resumido lo que he visto.
- Hyalorbilia 1: Parecen ser las de mayor tamaño y más amarillentas. Posible H. latispora.
- Hyalorbilia 2: Apotecios blancos, más pequeños. H. multigutulata. Tengo la impresión de que crece sobre sustrato ennegrecido por presencia de otros ascomicetos, pero no he observado un número suficiente como para confirmarlo.
- Hyalorbilia 3: Tambien blanca y pequeña. H. judiae.

Re : Hyalorbilia?
Thanks a lot, this was great! Nothing to add, except that Hyalorbilia generally shows tentencies to grow on other fungi.
