Gremmeniella balsamea sp. nov. on balsam fir in Canada

摘要

Gremmeniella balsamea sp. nov. is described from specimens collected on balsam fir ( Abies balsamea ) in eastern Canada. This is a fungal pathogen specific to balsam fir. Until now, it was considered to be G. abietina var. balsamea , this variety including also a Gremmeniella fungus on spruces. Consequently, this new species causes changes in the taxonomy within the genus Gremmeniella .
