The Venturiaceae in North America

摘要

Thirteen genera are recognized in the family Venturiaceae (order Pleosporales, Loculoascomycetidae) in temperate North America. Eighty entities are included. Ten of these are new to science:Venturia fagi, V. pruni, V. canadensis, V. alaskensis, Xenomeris abietis, Antennularia oxydendri, A. alpinavar.major, A. variisetosa, A, latispora, andA. ledi. Sixteen are new combinations:Venturia syringae(H. Syd.),V. rhamni(Bonar),V. weiriana(Petrak),V. juncaginearum(Lasch),Stigmatea pulchella(Cke. amp; Peck),Coleroa sporoboli(Greene),C. plantaginis(Ell.),Gibbera vaccinicola(Dearn. amp; House),G. cercocarpi(Ell. amp; Ev.),G. distegiae(Tracy amp; Earle),G. gaultheriae(Ell. amp; Ev.),Antennularia maculosa(Ell.),A. curviseta(Peck),A. fimiseda(Mout.),A. grossulariae(Auersw. amp; Fleischh.),A. vancouverensis(Dearn.). The new nameVenturia minutais proposed to replace the invalidV. microsporaNuuml;esch andVenturia acerinaPlakidas ex Barr is validated with a Latin diagnosis. The genusVenturiais subdivided into two subgenera:Venturia, comprising sectionsVenturia,Phaeosphaerella(Karst.) stat. nov.,Endostigme(H. Syd.) stat. nov., and subgenusSpilosticta(H. Syd.) stat. nov., comprising sectionsSpilosticta,Maculasect, nov.,Coleroideasect. nov.Coleroacontains the subgeneraColeroaandHormotheca(Bon.) stat. nov.Gibberais divided intoGibberaandVenturioidessubg. nov., andAntennulariainto subgeneraAntennularia,Capnodasubg. nov.,Gibberoideasubg. nov., andProtoventuria(Berl. amp; Sacc.) stat. nov. A number of species which have been described inVenturiaor other genera of the Venturiaceae are excluded from the family. Disposition of these taxa is made, including the new combinationsWentiomyces fimbriatus(Dearn. amp; House) comb. nov. andNematostoma occidentalis(Ell. amp; Ev.) comb. nov.
