云南竹子上的黑痣菌属的两个新种
Two new species of Phyllachora on bamboo leaves in Yunnan Province,Southwest China
摘要
Abstract
Bamboos belong to the subfamily Bambusoideae,representing a large group within the family Poaceae.Fungi of the genus Phyllachora are commonly found on bamboos;however,the species diversity of bamboo-inhabiting Phyllachora remains poorly understood.In the present study,two new species of Phyllachora collected from bamboos are described and illustrated using a combination of morphological and molecular phylogenetic approaches.These are Phyllachora dendrocalamicola on Dendrocalamus giganteus,and P.phyllostachydicola on Phyllostachys nigra var.henonis.P.dendrocalamicola possesses ellipsoidal ascospores,measuring 13-18×5-8 μm.P.phyllostachydicola has long-ovate ascospores,rounded at the apex and acute at the base,measuring 19-26×7-10 μm.关键词
