Hyphodiscus/Cistella on old stromata of Hypoxylon
Enrique Rubio, 24-02-2014 20:17
Enrique RubioCan anyone help with these gregarious, small (up to 0.3-0.4 mm) sessile, white to amber, slightly gelified apothecia growing on old stromata of Hypoxylon grex rubiginosum? I don't know if the sustrate is reddening because the host is red.

The hairs are very difficult to dissociate and they are hyaline, long cylindrical, with no clavate and verrucose apices. Asci IKI red with croziers. Paraphyses with some colourless Vb's.


I think could be an Hyphodiscus species, maybe the Hyphodiscus 'cistella' of Baral's folders but perhaps it could be Nannfeldt's Cistella geelmuydenii. Or these two fungi are conspecific?


What do you think?


Thanks again

Hi Enrique

it may be this Hyphodiscus "Cistella", though the oil drops in the spores are not the same. But it would be important to make a section or otherwise test the ectal excipulum which is strongly gelatinized there (see below). 

Also the yellow pigment which is sporadically present on the exterior would be worth to see.

Thank you, Zotto


My material is now dried but, when it was alive, I don't remember an strongly gelatinized tissue as your pic shows.
