Open Access Calonectria species and their Cylindrocladium anamorphs: species with clavate vesicles

The present study compares all known species of Cylindrocladium that have clavate vesicles. Several isolates were obtained from baited soils collected in various parts of the world, while others were associated with leaf litter or symptomatic plant hosts. Isolates were compared based on morphology, as well as DNA sequence data from their β-tubulin and histone gene H3 regions. Cylindrocladium australiense and Cy. ecuadoriae, are described as new species, a decision based on morphology and molecular data. A group of isolates associated with toppling disease of banana in the West Indies is identified as Cy. flexuosum. An epitype is designated for Cy. ilicicola, and a new name, Curvicladiella, proposed to replace the anamorphic genus Curvicladium, which is a homonym. Taxonomic novelties: Cylindrocladium australiense Crous& K.D. Hyde sp. nov., Cylindrocladium ecuadoriae Crous & M.J. Wingf. sp. nov., Curvicladiella Decock & Crous nom. nov., Curvicladiella cignea (Decock & Crous) Decock & Crous comb. nov.

  • Studies in Mycology is an international journal which publishes systematic monographs of filamentous fungi and yeasts, and special topical issues related to all fields of mycology, biotechnology, ecology, molecular biology, pathology and systematics. The journal is Open-Access and contains monographs or topical issues (5–6 papers per issue). There are no restrictions of length, although it is generally expected that manuscripts should be at least 50 A4 pages in print.
