Abstract: A field survey and culture study of the microalgae living on the shells of the intertidal prosobranch mollusc, Tricolia pulloides (Carpenter, 1865), aroun the Monterey Peninsula, California have identified the microalgae commmonly found growing on these shells and have shown that some of these microalgae are in greater abundance on shells from a wave exposed coast as compared to shells from a wave protected coast. Conchocelis rosea Batters, a shell-boring red alga not expected in high intertidal shells, was commonly found. An encrusting green alga identified as Pseudopringsheimia apiculata Setchell & Gardner showed free radiating irregularly branched marginal filaments in monostromatic regions and horizontally elongated cells in polystromatic regions, neither of which had been described for P. apiculata on macroalgal hosts.
