dc.description.abstractSeveral Calonectria (Ca.) and Cylindrocladium (Cy.) species were recovered from alfalfa-baited soil samples gathered in Colombia and Venezuela. Perithecia of Calonectria naviculata sp. nov. formed in culture when Venezuelan strains of Gy. naviculatum were crossed with ex-type Brazilian strains. Calonectria gracilipes sp. nov. (anam. Cy. gracilioideum sp. nov.), a homothallic species, was isolated from Colombian soils. Cylindrocladium graciloideum, Cy. gracile, Cy. pteridis and Cy. pseudogracile form a complex of morphologically similar species characterized by clayate vesicles and primarily 1-septate conidia. Each species could, however, be distinguished using RFLP banding patterns. A key to Calonectria spp. having Cylindrocladium anamorphs with 1-septate conidia is also presented.
