Cladobotryum-Konidienformen von Hypomyces-Arten

The genus Cladobotryum Nees is characterized by mostly verticillately branched conidiophores with phialides, dry, one-celled or pluricellular conidia in heads or irregular chains, and pluricellular chlamydospores or sclerotia. Eight species are considered. In four of them the corresponding Hypomyces state is known, in one species it is conjectured. In cultures of Hypomyces rosellus and H. odoratus perithecia were obtained after mating of compatible strains. The conidium-forming cells are interpreted as phialides in all species, even if the meristematic zone extends beyond the apex and surrounds itself with a secondary wall.
