| Abstract/Contents: | "Conidiomata of the Gliocladium-like endophyte of ryegrass (Lolium perenne L.) formed in air lacunae of senescent outermost leaf sheaths during winter. Each conidioma originated on a vegetative hypha as a swelling which enlarged to form a conidiophore that maintained connection with the parent hypha by a septal pore. The swelling was enclosed within the mucilaginous coating of the parent hypha and was also covered by a fibrillar cap which ruptured as the conidiophore elongated. Each conidiophore bore one or more conidiogenous cells (phialides) either laterally or subterminally and, in addition, bore a terminal or lateral conidium. The conidiogenous cells continued to produce conidia and further conidiogenous cells sympodially. A marked difference in ultrastructure and lipid content of the endophyte was evident between the vegetative hyphae and the cells of the conidioma. The site of initiation of the enteroblastic conidium was indicated by a fibrillar cap, which ruptured to form an upstanding collarette around the base of the conidium. A succession of conidia produced a thickening in the neck region at the apex of the conidiogenous cell. The principal features distinguishing these sheath conidiomata from those occurring in the leaf blade (Philipson, 1989) include conidiomata initiation, form of branching and shape of cells, the presence or absence of a fibrillar cap over the conidial locus, and, possibly, the mode of conidial secession." |
