The Sexual Mechanism of Sclerotinia Gladioli

摘要: Intensive cytological work has been done by several investigators on a few Ascomycetes, but in the majority of genera there is no knowledge sexual mechanism involved formation perithecia and apothecia. As result, dearth ot fundamental information which would form basis for any theories as to phylogenetic relationships this group more thorough life histories these fungi. Cytological experimental with Sclerotinia Gladioli revealed presence sex organs consisting receptive bodies microconidia; spermatization between compatible isolates be? ing necessary production On this, paper be published Phytopathology, writer proposes new binomial (Massey) Drayton fungus previously known Sclerotium Massey, includes technical description illustrations structures, brief historical resume disease it responsible. It only recently that organism brought out facts. In preliminary account (10), re? ported microconidia S. function spermatia, made reference structures certain discomycetous lichens some Laboulbeniales, are regarded functional spermatia. Microconidia type found have past century
