The decomposition of Fontinalis antipyretica var. gracilis was studied with the litterbag technique in a softwater stream between May and October. The daily exponential decay coefficient was 0.0054. Phenolics declined exponentially from an initial value of 1.43 % with a daily loss rate of 3.9 %. A total of 22 aquatic hyphomycete species was found on moss during 20 wks. of stream exposure, with the numbers per sampling date fluctuating between 4 after one wk. and 16 after 8 wks. Ergosterol content of decaying moss reached a maximum of 373 µg/g dry mass. Spore production and ergosterol levels in live stream-collected moss (May to November) were less than 1 % of the maxima of litterbag moss.
