Lennert GeesGreetings!For my master's dissertation I work on c
Hi againI'd like to know your opinion about this 'ceratostomelloid' fungus growing on rotten wood of Fagus sylvatica. The beaked, scattered, glabrous, inmersed perithecia are up to 1 mm high with only the long necks erumpent across the surface.
The asci are cylindrical, shortly stipitate, 63-85 x 6-7 microns, with an conspicuous apical apparatus IKI negative and 8 ascospores obliquely uniseriate. Paraphyses septate tapering at the end. Ascospores 8.5-11.5 x 4.3-4.9; Q = 1.96-2.58, allways 2-guttulate, smooth, maybe porate (?).
I think this fungus agrees better with Xylomelasma than Ceratostomella. What do you think?
Thanks again
Xylomelasma sordida seems to be a good match. Did you observe the peculiar ascogenous cells at the base of the asci, as described by Réblova? You have to make a very thin slide to see them, hard job!
Saludos,
Jacques
Bonsoir Jacques
It's really hard! Because the interascal tissue is dense and very little congophilous
Thanks gain!
