Endosporium, a new endoconidial genus allied to the Myriangiales
A new endoconidial genus, Endosporium gen. nov., is reported from Alberta, Canada. Two species are described: Endosporium populi-tremuloidis Tsuneda sp. nov. (type species) isolated from a heavily colonized bud of Populus tremuloides Michx., and Endosporium aviarium Tsuneda sp. nov. isolated from th...

This genus is morphologically similar to Phaeotheca in forming black, slow-growing colonies (conidiomata) containing numerous, conidiogenous, cellular clumps, but different in that (i) colonies possess aerial, determinate hyphae on the surface; (ii) mature colonies eventually collapse to release a mixture of conidiogenous cellular clumps, endoconidia, and blastic conidia in slimy liquid; and (iii) endoconidia are hyaline.
