| Abstract/Contents: | "Intercellular hyphae were observed in the leaf sheaths of meadow fescue plants from 7 of the 8 ecotype collections from Hokkaido. The hyphae were convoluted, hyaline, with infrequent branches, and ran parallel to the vascular bundles. It was confirmed using scanning electron microscopy that the hyphae in the leaf sheaths were confined to the intercellular spaces. Colonies of the endophytic fungus grew very slowly on PDA, 0.2-0.5 mm/day at 25°C on PDA, with the optimum temperature for growth being 25°C. The colonies were whitish to rosy buff, felted, forming aerial hyphae from which numerous phialides arose. The phialides were straight or slightly flexuous, 4-17 μm long, and 0.8-1.6 μm wide gradually tapering to 0.6-0.9μm towards the tips. Each phialide produced a single uncinate conidia, and the appearance of the colonies are identical to those described for Acremonium uncinatum in meadow fescue in Eurpoe and New Zealand. Accordingly the endophytic fungus in meadow fescue in Hokkaido has been identified as Acremonium uncinatum Gams, Petrini et Schmidt." |
