摘要
Abstract
Four specimens of a metacapnodiaceous sooty mould occurring on living twigs and leaves of the conifer Abies veitchii were collected in October 2019 from the Sugadaira Plateau,Nagano,central Honshu,Japan.These were assigned to the known sooty mould Capnobotrys neesii,the type species of the genus Capnobotrys.In addition,a repre-sentative strain(JCM 39119)was cultured from a single conidium,producing moniliform hyphae bearing sympodial conidiogenous cells and conidia,and phialides and microconidia resembling those growing on natural hosts.Following the protocol for re-assigning the scientific name of pleomorphic fungi,the asexually-typified species C.neesii is trans-ferred to Metacapnodium as Metacapnodium neesii comb.nov.The nrLSU,nrSSU,ITS,RPB2,and EF1α gene se-quences for JCM 39119 were determined.Phylogenetic analysis based on the nrSSU DNA sequences positioned JCM 39119 at the base of the taxon Chaetothyriales,rather than Capnodiales or Pleosporales as expected.However,further assessments including other gene sequences are required to conclusively place.Our results support revision of the higher-level classification of Metacapnodiaceae typified by Metacapnodium.关键词
