Stefan BlaserHi everybody, This collection was collected by JÃ
Este homgo lo encontré en la Sierras de Cazorla, Jaén, se que es Gibberella, pero no se cual puede ser. ¿Alguien tiene unas claves para Gibberella, o sabe cual podrÃa ser?
Peritecios generalmente gregarios, que irrumpen de entre la corteza de Ulex parviflorus. Los peritecios son de color marrón con brillos metálicos, que en el microscopio son azul oscuro, de (268,92) 286,91 - 350,39 (368,74) µm. Me = 318,90 µm de anchura.
Ascas biseriadas, no amiloides, de (89,57) 91,35 - 113,78 (116,78) x (10,62) 12,77 - 14,72 (14,83) µm.
Me = 102,30 x 13,50 µm.
Esporas lisas, hialinas, algo curvadas, con 3 septos trasversales de; (20,26) 21,29 - 25,36 (27,38) x (6,12) 6,49 - 7,56 (8,00) µm
Q = (2,74) 2,85 - 3,65 (3,82) ; N = 33
Me = 23,23 x 7,09 µm ; Qe = 3,29
Gracias.
Saludos.
Salvador.
¿Tiene claves para Gibberella? si es asÃ, le pido que me las envÃe, por favor.
Yo he mirado en las claves que aparecen en MEDARDI G. (2006) Atlante fotografico degli Ascomiceti d'Italia. A.M.B. Fondazione Centro Sttudi Micologici. y me dice que G. pulicaris tiene esporas de 18-21 x 5-7 µm.
Gracias.
Saludos.

it is not easy to work with this genus, but compare also with Enrique Rubio's data here on ascofrance. In my opinion, after several collections of G. cyanogena and G. pulicaris, there is a difference in spore measurements: spores of G. cyanogena are smaller, often not more than 6µm broad. Length is rather variable between 21 and 31µm.
I do not really know but I think that G. pulicaris fruitbodies are always brown, like cacao, and G. cyanogena very dark brown to blackish brown.
I had a key for this genus, but unfortunately I am still working on organizing my data into an Excel list. For now I cannot find the doc (sorry for that).

No te preocupes por las claves, ya me has ayudado bastante.
Saludos.
Salvador.
the genus Giberella is impossible without to know the anamorphs as you can see in the attached key.
Best regards,
Christian
HabÃa leÃdo algo sobre esto, pero tampoco estaba seguro. La dejaré como Gibberella aff. pulicaris.
Saludos.
Salvador.
Cordialement
