Studies on Chrysophyceae from some ponds and lakes in Alaska. I

Mallomonas species examined with the electron microscope
  • Berit Asmund
  • Douglas K. Hilliard


  1. I.

    An account is given of the following habitats in Alaska from which species of Synura and Mallomonas were collected: three unnamed ponds near Anchorage, Karluk Lake on Kodiak Island, temporary pools near Cape Thomson, and Lake Louise and Lake Susitna (62° 23′ N 146° 21′ W). The account includes notes on topography, geology, vegetation, temperature, and chemistry at the time of sampling, classification, and phytoplankton content.

  2. II.

    Description of Mallomonas pseudocoronataPrescott and a new species, M. corymbosa and reports on six other species from the above- mentioned localities. Electron micrographs of scales and bristles are shown. Notes are made on periodicity, ecology, and sociology.

  3. III.

    Discussion of the designation of M. caudata.
