MELITTOSPORIUM Corda, Icones Fungorum hucusque Cognitorum 2: 23, 1838. Rhytismatales. fam. incert. 1 Ukrainian species on various woody plants.

Melittosporium versicolor (Fr.) Corda, Icones Fungorum hucusque Cognitorum 2: 23, 1838. Status. 4 records since September 1995; apparently not uncommon in the mountains near Yalta. Months. September. Regions. Crimea. Habitat. On dead, fallen, decorticated, rather white wood of various trees. Notes. This fungus appears not to have been previously reported from Ukraine; there is a lot of nomenclatural confusion between this fungus and, amongst others, Propolomyces farinosus; in the present work, Melittosporium versicolor is interpreted as a species with a bluing hymenium, thick-walled asci and more or less ellipsoid ascospores with longitudinal as well as transverse septa (suggesting that this species could have affinities with some bitunicate ascomycetes), whereas Propolomyces farinosus is regarded as a species with a white hymenium, thinner ascus walls, and reniform aseptate ascospores. Worldwide. Rather poorly recorded, but probably widespread on wood of various trees. References. Sherwood (1977) [description].
