AbstractDuring a study of some Tulasnella species from the Bourdot herbarium (PC), I examined a specimen collected by Galzin in 1909 and identified by Bourdot as Tulasnella vernicosa. Since many species of Tulasnella in dry state are invisible to the naked eye, I had to make sections of several parts of the wood surface, but could not detect the typical Tulasnella basidia with strongly inflated sterigmata. Instead of a Tulasnella, I found some clampless hyphae, strongly urniform basidia with short, subulate sterigmata, and basidiospores of a very unusual shape: they were distinctly forked or two-lobed, with two diverging parts.
A study of the literature showed this to be a North American species of Galzinia, viz. G. geminispora Olive. This species seems to be very rare in North America (or at least seldom found and reported) and is new to Europe. Because of the unusual shape of the spores, it seems worthwhile to draw attention to this remarkable taxon which, unfortunately, can only be found by chance.
