Hamatocanthoscypha on Cupressus leaves
Enrique Rubio, 09-01-2013 20:25
Enrique RubioHi again

This material was sent to me from M. Tapia (Navarra, NE of Spain) as Hamatocanthoscypha species growing on rotten, blackish, leaves of Cupressus. The ascomata are minute, briefly stipitate and allways white.

The spores are ovoid eguttulate or provided of 1-2 small polar guttules. Asi IKI negative (-), croziers positive (+). Paraphyses with any content. Ectal excipulum elongate of and + or - elongate textura prismatica. Hairs granulate, many of them uncinate.

I think is a good Hamatocanthoscypha species that not fits well with H. obsoleta. In Zotto's CD there is an Hamatocanthoscypha 'rotundispora' HB- 7444 that is very close with this fungus.
What's your opinion?


Many thanks again
Enrique

I do not understand the name (by Raitviir & Galán), because also in the type the spores are ellipsoid. But yours is certainly the same species as the one found by Jean-Paul.

Thanks, Zotto. Really the spores are not roundish!
Have you the original description in Nova Hedwigia?

Re : Hamatocanthoscypha on Cupressus leaves
In Raitvir's paper, Revised Synopsis of the Hyaloscyphaceae (2004), the spores appears to be roundish and the texy says 'spores broadly elliptical to subglobose without lipid guttules, 3.2-3.6 x 2-2.3 microns' It seems to be smaller for our fungus...

Oh yes, my database contained an error, 6 instead of 3.6 µm.

Here the description
