Anthostomella on sand dunes
Enrique Rubio, 30-03-2015 14:15

Hi to all


This Anthostomella grew on wet dead stems of Ammophila arenaria. The fungus makes clypeate single blackish perithecia with papilate ostioles. Asci with a massive IKI positive apical apparatus longer than broad. Ascospores broadly inequilateral with spiral germ slit and peculiar partial gel sheaths at the poles. I think don't fits with A. spiralis or A. umbrinella.


Some idea for help me?


Thanks again

Hi Enrique,

This could be Anthostomella lugubris, a species we find on Ammophila in our country.

Re : Anthostomella on sand dunes
Thanks Bernard but A. lugubris is said with shorter and narower ascospores with no so gel sheaths. and germ slits

Re : Anthostomella on sand dunes

Hi friends,


Again an amazing record of Enrique !


Clearly it isn't A.lugubris.


 Closer than this last one is A. umbrinella, you saw it,  but host and  macroscopy don't fit. Thus appendages are lacking. Exit this hypothesis.


You can find it in Rappaz (into the genus Leptomassaria). Both species, L.simplex andL.  unedo, are corticolous.


A. francisiae has such apical appendages, but the germslit is straight. Exit again.


My conclusion is that your Anthostomella is perhaps new.


Alain
