Urceolella on Saxifraga
Enrique Rubio, 15-06-2015 18:06
Enrique RubioHi to everybody

I'd like to know your opinion about these very small, scattered, white, shortly stipitate, cupulate, urceolate, up to 0.25 microns high, with ciliate margins, covered by fascicles of glassy strongly refractive hairs IKI negative only with basal lumen, up to 52 x 4.5, glassiness lost in KOH 10%.


Asci up to50 x 8, 8-spored, IKI bb, arising from croziers. Paraphyses filiform. Ectal excipulum of an elongated textura prismatica.


The apothecia grew on dead leaves of Saxifraga babiana subsp. septentrionalis, a cantabric endemism with viscid leaves growing on calcareous rocks at 1700 m of altitude (La Farrapona-Somiedo-Asturias).


I feel the correct genus could be Urceolella and so it seems to be close to Urceolella saxifragae Svrcek that grows on Saxifraga aizoon with somewhat similar characters but longer ascospores and IKI negative asci (fide Raitviir). I attach Svrcek and Raitviir's description of U. saxifragae.


 


Many thanks in advance

Re : Urceolella on Saxifraga
Indeed the spores looke quite different. Seems to be an endemism too...

very nice fungus!

No more to say but that's again a nice plate for a nice fungus from the Farrapona. Merci ENrique de donner des nouvelles régulièrement de ce paradis !
