“…The sheathed ascospores and synnematous anamorph of this species (Davidson 1971;Upadhyay 1981;Mouton et al 1992) closely resemble those of species such as G. olivacea (Mathiesen 1951), G. sagmatospora (Wright andCain 1961), G. davidsonii (Olchowecki andReid 1974) and G. cucullata (Solheim 1986), supporting the new combination provided here.

“…Not surprisingly, all the species grouping with G. olivacea based on our analyses (Figs. 1, 2) have similar teleomorphs and synnematous anamorphs: G. sagmatospora (Wright and Cain 1961), G. olivaceapini (Davidson 1971), G. davidsonii (Olchowecki and Reid 1974), and G. cucullata (Solheim 1986).…”

“…olivaceapini was initially described from Dendroctonus and other beetle species on pine in the USA (Davidson 1971), but has to the best of our knowledge not been reported again. In this study, isolates related to these two species were most frequently isolated in association with D. autographus, but also from eight other bark beetle species infesting both pine and spruce.…”

Species of Grosmannia with Leptographium anamorphs include important forest pathogens and agents of blue stain in timber. They are commonly found in association with forest pests, such as bark beetles. During a survey of ophiostomatoid fungi in eastern parts of Finland and neighboring Russia, species belonging to the genus Grosmannia were isolated from 12 different bark beetle species infesting Picea abies and Pinus sylvestris, the most economically important conifers in the region. Identification of these fungi was based on morphology, DNA sequence comparisons for three gene regions and phylogenetic analyses. A total of ten taxa were identified. These belonged to six different species complexes in Grosmannia. The phylogenetic analyses provided an opportunity to redefine the G. galeiformis-, L. procerum-, L. lundbergii-, G. piceiperda-, G. olivacea- and G. penicillata-complexes, and to consider the species emerging from the survey within the context of these complexes. The species included G. galeiformis, G. olivacea, L. chlamydatum, L. lundbergii, L. truncatum and a novel taxon, described here as L. taigense sp. nov. In addition, species closely related to G. cucullata, G. olivaceapini comb. nov., G. piceiperda and L. procerum were isolated but their identity could not be resolved. The overall results indicate that the diversity of Grosmannia species in the boreal forests remains poorly understood and that further studies are needed to clarify the status of several species or species complexes.

“…Perithecia of O. microcarpum are much smaller than those of these four species (Mathiesen-Käärik 1953;Hunt 1956;Olchowecki and Reid 1974;Davidson 1971;Upadhyay 1981). Ophiostoma microcarpum has unique ostiolar hyphae on the perithecial neck, which are hyaline and hyphoid.…”

Three species of Ophiostoma possessing Pesotum anamorphs isolated from bark beetles and their galleries infesting Abies species in Nikko, Japan, are described as new species. Ophiostoma nikkoense is characterized by brush-shaped synnemata producing long septate clavate conidia, perithecia with neck, and allantoid ascospores. Ophiostoma microcarpum has smaller perithecia with hyphoid ostiolar hyphae on the neck, and the ascospores are cylindrical or ossiform in side and face views. Ophiostoma abieticola has perithecia without ostiolar hyphae on the neck and produces orange-section-shaped or reniform ascospores.

New Leptographium species from Indonesia and Eastern North America

2000

Leptographium species have predominantly been described from North America, Canada and Europe. These fungi generally occur on conifers and many cause blue-stain of lumber. Most Leptographium species are also associated with insects and in particular, bark beetles (Coleoptera: Scolytidae). Recently, an unknown species of Leptographium was isolated from pine infested with an Ips sp. in Indonesia. In addition, two unknown species have been collected from red spruce (Picea rubra) and balsam fir b4bies balsamea) roots from high elevation sites in Eastern North America. The latter isolates are unusual in that they are associated with the feeding wounds made by the conifer swift moth Korscheltellus gracilus (Lepidoptera: Hepialidae), which is a habitat unique for species of Leptographium. Comparison with known Leptographium species has revealed that the isolates from Indonesia and those from Eastern North America represent three previously undescribed taxa. They are, therefore, described in this study as L pineti sp. nov, L abieticolens sp. nov. and L. peucophilum sp. nov.
