| Abstract/Contents: | "Systematic studies were conducted on populations of Epichloë spp. in England infecting host grasses Agrostis capillaris L., Dactylis glomerata L., and Holcus lanatus L. Three species of Epichloë are described and two, E. baconii White and E. clarkii White, are proposed as new, being distinguishable from the type by disarticulation of ascospores to form uniquely shaped part-spores. In E. baconii, filamentous ascospores disarticulate to form 1-septate, cylindrical part-spores. In E. clarkii, multiseptate, spear-shaped part-spores form. The type species E. typhina ejects filamentous ascospores entire and does not form part-spores. Reproductive compatability between species was examined. Intraspecies crosses were found to yield a dense layer of perithecia that differentiated asci and ascospores internally. Interspecies crosses gave one of three results, including no reaction, necrotic browning, or perithecia that did not mature. Culturally all three species examined in this study are classifiable in the form species Acremonium typhinum Morgan-Jones & W. Gams. This suggests the possibility that within the group of turfgrass endophytes that are identifiable as A. typhinium multiple Epichloë species may be represented." |
