ADDITIONAL RECORDS: Recovered from moss scraped from a rock, Eramosa River bank, Guelph, Ontario, September 1988.

Hyphae of C. longispora are 6.2-7.5 µm wide, colourless, septate, and uniform in width (Figs. 16, 17). The hyphae are straight and sparingly branched, with most branches originating at right angles to the parent hyphae (Fig. 15). Adhesive pegs are 10.5-23.5 µm x 5.5-7.5 µm (Figs. 16, 17, and 21). Adhesive pegs tend to be broadest at or near the base and taper gradually to a rounded apex. They do not have the well-marked apical bulb of C. muscicola. In young cultures the pegs are more or less uniform in length, but as the hyphae age, a number of pegs continue growth and they lack the uniformity in size found in C. muscicola. Conidiogenous cells (Figs. 14, 20) are similar to those found in C. muscicola. Often, however, conidia are produced terminally on long branches (Fig. 21). These branches may be up to 200 µm long and have the appearance of conidiophores. This pattern of development takes place in water; thus a branch with a terminal cluster of conidia is not actually a support structure. If cultures are drained and conidia allowed to develop in air, conidiogenous cells are produced directly from prostrate hyphae, and elongate conidiophores are not produced. Conidia are very long, colourless, and multiseptate and have a marked curvature at the distal end (Figs. 14, 18, and 22). They range from 125-228 µm long and are 8.5-10 µm wide. In the presence of rotifers they develop from one to eight adhesive pegs directly from the cells (Figs. 18, 19, and 22). The species description is based on isolate No. 117.
In all the important aspects of its life cycle C. longispora is the same as C. muscicola. Cephaliophora longispora differs from C. muscicola in having much larger conidia (averaging more than 50 µm longer). Also, conidia of the latter have a strong curvature at the distal end, giving them a clawlike appearance in a cluster (Fig. 22). The adhesive pegs in C. longispora appear relatively short and squat and of a different shape. They are broader at or near the base and taper gradually to the apex. In C. muscicola the conidiogenous cells always arise directly from the hyphae, whereas in C. longispora the conidiogenous cell may be terminal on a more or less elongate lateral branch.
Tests showed that both species of Cephaliophora described above could capture and colonize tardigrades.
