Epitypification of Ophiostoma galeiforme and phylogeny of species in the O. galeiforme complex
Mycologia 96 (6), 1306-1315
Abstract: Ophiostoma galeiforme was described first in 1951 from Larix kaempferi in Scotland, where it was found to be associated with the bark beetles Hylurgops palliatus, Dryocoetes autographus, and the ambrosia beetle Trypodendron lineatum. The taxonomy of this fungus has been uncertain because of a lack of sexual structures on the type specimen and contamination of a preserved ex-type culture. The aim of this study was to clarify application of the species name, O. galeiforme, by designating an epitype and to consider phylogenetic relationships of the species. Nineteen isolates resembling O. galeiforme from different parts of the world were used, including collections from Pinus sylvestris infested with Tomicus piniperda in Scotland and the contaminated ex-type culture. Morphological characteristics of isolates from Sweden, South Africa, Scotland, Chile and Austria corresponded well with those originally described for O. galeiforme, and an isolate from Scotland is designated as the epitype. A detailed description is provided. Results of interfertility tests showed that O. galeiforme is heterothallic. Analysis of ITS rDNA sequences showed that the isolates representing O. galeiforme were distinct from three morphologically similar isolates from the USA and Mexico, which probably represent an undescribed taxon.
