Abstract: The results of an investigation of the soil algal flora from three different sites on a farm in Pike County, Pennsylvania, are presented. Representatives of 29 genera were recorded of which Chlamydomonas, Hormidium, Chlorococcum, and Tetracystis were most frequently encountered, and in that order of frequency. Only four blue-green algae, Anabaena, Lyngbya, Nostoc, and Schizothriz were present in these soils. The diversity and frequency of occurrence increased between late winter and early summer. Species of Nannochloris, Stichococcus, and Chlamydomonas developed in soils inoculated into sea water enrichment medium (35% salinity).
