Arthrographis pinicola sp.nov. (Hyphomycetes) is described; it was isolated from galleries and adult beetles of Ips latidens and from galleries of Dendroctonus ponderosae in Pinus contorta var. latifolia in western Canada. In I. latidens infested lodgepole pine, this species extensively colonizes nuptial chambers and egg galleries, characteristically forming floccose conidiomata composed of repeatedly branched hyphae which divide to form arthroconidia having schizolytic dehiscence. The fungus is antagonistic to some blue stain fungi in vitro. Arthrographis pinicola is compared with other species of Arthrographis, and with Arthropsis microsperma and the discomycete Pezizella chapmanii.
