White Calycina on indeterminate moncot
Enrique Rubio, 17-09-2014 18:20

Hi again


These gregarious, small (up to 0.5 mm high, 0.8 mm broad), shortly stipitate, elastic, fully withish ascomata, not reddening with the age were growing on old leaves of indeterminate monocots of I think grasses, not sedges but I'm not absolutely sure, at 1400 m of altitude on acid montane soil. Apothecial margins are only finely fimbriate.


Ascospores hyaline, 1-septate, with may small lipid guttules that seem to form conidia. Asci IKI r (obviously b after KOH pret.), 8-spored, with no croziers or only small protuberances of abortive croziers. Excipulum built by a gelatinised tissue (textura oblita).


I think in Calycina as the correct genus for it but I don't know a good species that matches with it. Calycina herbarum has not croziers too but their ascospores are longer.


Can you help me?


Thanks again

Re : White Calycina on indeterminate moncot
Hi Enrique,
did you consider Allophylaria as a genus for this finding, the excipular structure and IKI red asci point in that direction

cheers,
Stip

Re : White Calycina on indeterminate moncot

Hi Stip


I don't think this is an Allophylaria species and I'm almost sure is a Calycina with gelatinized tissues as many Bisporella species now recombined in Calycina.


 


Thank you, Stip

Re : White Calycina on indeterminate moncot
Hi Enrique,
you could be right about that, this option did not cross my mind. I that case look at Zotto's Cubby in Calycina white/ heterospora monocots, unfortunately croziers are not depicted and if a different IKI solution is used it could turn blue. Of course this is just a hint, ask Zotto for measurements of this collection.
Cheers,
Stip
