The first record of <i>Aphanodesmium gabretae</i> (<i>Helotiales</i>, <i>Leotiomycetes</i>) on natural substrate reveals a contrasting distribution of its two genotypes.

A short report is given on the first find of the poorly known species Aphanodesmium gabretae . This sporodochial anamorphic ascomycete was previously only known as an endophytic isolate from a spruce needle. The newly obtained collection originated from bark of a living spruce twig. Both specimens have an identical morphology, but comparison of their rDNA showed polymorphism. Thanks to the GlobalFungi database, we have been able to demonstrate a contrasting geographical distribution of the two genotypes differing in the rDNA cistron.
