Tricladium varicosporioides on indet. decorticate
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!
