The Peridial Development and Dehiscence Mechanism of Cryptendoxyla hypophloia, a Cleistothecial Ascomycete Isolated from the Bodies of Arthropods
Download2004
Currah, R.S., Greif, M.D., Tsuneda, A.
Cryptendoxyla hypophloia is a rarely reported cleistothecial ascomycete that has a cephalothecoid peridium comprising six to eight plates that split apart at maturity to expose the ascospores. Three new isolates from the bodies of live-trapped insects represent circumstantial evidence supporting...

Phialocephala urceolata sp. nov. was isolated from a black film that had developed on a watersoluble proprietary heparin solution (pH 2.5). Morphological and enzymatic characters, along with phylogenetic analyses of rDNA sequence data, indicated that the conidial fungus is closely related to...

Atradidymella muscivora (Pleosporales) is a bryophyte pathogen that infects the mosses Aulacomnium palustre , Hylocomium splendens , and Polytrichum juniperinum . Light and scanning electron microscopy and extracellular enzyme production were used to characterize the interactions between this...

Skinner, S., Currah, R.S., Tsuneda, A.
Light and electron microscopy showed that the reticuloperidium of thick-walled hyphae, characteristic of the mature ascoma of Auxarthron conjugatum, originated from branches that grew from the broad, gyre-like hyphal loops making up the ascomatal initials. Within the developing peridium, short,...

Morphology and Phylogenetic Placement of Endoconidioma, a New Endoconidial Genus from Trembling Aspen
Download2004
Tsuneda, A., Hambleton, S., Currah, R.S.
Endoconidioma populi gen. et sp. nov. is described from black subicula on twigs of trembling aspen, Populus tremuloides, in Alberta, Canada. Pycnidium- like conidiomata are produced on twigs and in culture, but, unlike pycnidia, conidiomata of E. populi have a closed peridium and a locule filled...

Background Insects constitute the vast majority of known species with their importance including biodiversity, agricultural, and human health concerns. It is likely that the successful adaptation of the Insecta clade depends on specific components in its proteome that give rise to specialized...

Retroposition is widely found to play essential roles in origination of new mammalian and other animal genes. However, the scarcity of retrogenes in plants has led to the assumption that plant genomes rarely evolve new gene duplicates by retroposition, despite abundant retrotransposons in plants...

Evidence that the gemmae of Papulaspora sepedonioides are neotenous perithecia in the Melanosporales
Download2008
Tsuneda, A., Davey, M.L., Currah, R.S.
Papulaspora sepedonioides produces large multicellular gemmae with several, thick-walled central cells enclosed within a sheath of smaller thinwalled cells. Phylogenetic analysis of the large subunit rDNA indicates P. sepedonioides has affinities to the Melanosporales (Hypocreomycetidae). The...
