Monilia versiformia sp. nov. (Hyphomycetes) from a perennial Douglas-fir canker

Monilia versiformia sp. nov. is a pleoanamorphic fungus producing two types of blastoconidia, viz., monilioid chains of dark-colored, sphaeroid conidia and lunate, hyaline conidia produced singly on simple, conidiogenous hyphae. The chains are produced in great abundance, and as the conidia mature and become pigmented, the chains break down and form a sooty mass. The fungus was isolated from a perennial canker of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) in British Columbia, Canada.
