Cyathicula on Urtica stems
Enrique Rubio, 04-04-2017 17:54
Enrique RubioHi again
This Cyathicula species was growing on old stems of Urtica dioica at 900 m of altitude.
The ascomata are stipitate and fully whitish, with a fimbriate margin made by cylindric-clavate cells with many small refractive guttules as in the paraphyses. The ascospores have some small LBs at their poles and no septa. Asci IKI b, 52-68 x 5-7, without croziers. Ectal excipulum textura oblita covered by many crystals.
I think this collection deviates from typical Cyathicula cyathoidea, said to have croziers, so I'd like to know your opinion.
Many thanks again

Re : Cyathicula on Urtica stems
Spore length is interesting, anyhow, this seems to cope with the wide sense of cyathoidea - surely a collective species as sequences tell us.
