“…Most morphological features and colony appearances of our isolates are consistent with those published. The conidial width of our fungus agreed with that of Tzean et al (1997), but was somewhat broader than the descriptions of Brown and Smith (1957) and Samson (1974). The growth of the colony diameter corresponded with that of Samson (1974).…”

“…P. canadensis was originally described by Vuillemin (1925) as Spicaria canadensis. Brown and Smith (1957) did not observe this species themselves but combined S. canadensis into the genus Paecilomyces, and published on the species with the original Latin description of Vuillemin (1925). Brown and Smith (1957) regarded P. canadensis to be probably related to P. farinosus, but differed from the latter in having larger conidia.…”

An entomopathogenic fungus, Isaria javanica (anamorphic Cordycipitaceae) was isolated from diseased larvae of the gypsy moth, Lymantria dispar, in outbreak populations from Iwate Prefecture, in northern Japan in the summer of 2008. The fungus caused a mixed infection with Entomophaga maimaiga in the gypsy moth populations. The fungus forms conidial chains on phialides verticillate on conidiophores, with conidia fusiform to oval, 3.0-4.3-6.3ϫ 1.4-2.0-3.2 mm, chlamydospores and synnemata absent, and grows on SDAY medium at 10-30°C, with optimal growth at 25°C. Phylogenetic analyses, using the b-tubulin gene and internal transcribed spacer (ITS) rDNA, positioned the fungal isolates to a well supported branch where I. javanica was included. The dipping of larvae into the conidial suspension revealed a moderate virulence of the fungus to the gypsy moth (mortality 58-100% with 10 8 /ml). This is the first discovery of I. javanica on L. dispar larvae.

“…The one-celled (rarely two-celled) conidia are produced in dry, divergent or tangled basipetal, hyaline or slightly pigmented, smooth-walled or echinulate chains. Chlamydospores, when present, are usually thick-walled, smooth-walled or ornamented and borne singly or in short chains (Brown & Smith 1957, Samson 1974. Samson (1974) recognized two sections, i.e.…”

The ascomycetous genus Cordyceps accommodates endoparasitic species that attack arthropods or other fungi. Analyses of ITS nrDNA sequence data of 72 taxa from the teleomorph genera Cordyceps, Claviceps, Epichloe¨, and the anamorph genera Akanthomyces, Beauveria, Metarhizium, Hirsutella, Hymenostilbe, Paecilomyces, Polycephalomyces, and Tolypocladium assigned the taxa to four main evolutionary lineages not reflected in the current classification of Cordyceps. Ten subclades were recognized from separate analyses of data subsets. Judged from the ITS phylogenies, Cordyceps spp. with branched stromata were highly supported as a divergent lineage. Host specificity was found to be of limited phylogenetic significance, and several host shifts are suggested to have occurred during the evolution of Cordyceps. Similar ascospore morphology was not reflected in the phyletic groups, and closely related taxa showed large interspecific variation with respect to the number of segments in which the ascospores are divided. However, combinations of selected characters were found to delimitate some lineages, e.g. all Cordyceps spp. that attack hosts in the insect orders Coleoptera and Lepidoptera, and with non-immersed perithecia and clavate to acicular, brightly yellowish to reddish stromata, constituted a separate clade. Furthermore, all Cordyceps spp. with perithecia obliquely immersed in the stroma were recognized as a distinct monophyletic group. This clade is additionally characterized by the formation of anamorphs ascribable to the genus Hymenostilbe. The mycogenous Cordyceps spp. grouped in a separate subclade, interspersed by two cicadaen parasites and all Tolypocladium spp. except T. parasiticum. Tolypocladium and Beauveria were found to be polyphyletic. The included Claviceps and Epichloe¨taxa appeared to be derived within Cordyceps, thus making Cordyceps paraphyletic as suggested in other studies.
