Abstract

Aquatic hyphomycetes have been shown to be successful colonizers of leaf material in freshwater streams (Ingold 1956, 1966, 1975, 1984; Shearer and Webster 1985a,b; Webster 1981). The initial requirements for colonization of a fresh substratum are the formation and liberation of conidia by the parent colony; these reach a peak concomitant with leaf fall (Chamier et al. 1984; Shearer and Webster 1985a,b; Chap. 3). Increases in amounts and variety of substrata, water turbulence and rapid growth rates have been implicated in this seasonal periodicity of increased inoculum (Sanders and Webster 1980; Webster and Descals 1981; Suberkropp 1984). It has also been suggested (Shearer and Webster 1985b; Chaps. 4, 5) that species of aquatic hyphomycetes may possess a resting stage such as the teleomorphic and chlamydosporic stage for their survival during unfavourable conditions and to provide an inoculum when new substrata become available.
