Abstract

Twenty species of algae were identified in snow and ice collections from Alberta, California, Colorado, Montana, Nevada, Oregon, and Washington. Red resting spores of Chlamydomonas nivalis, zygotes of Chloromonas brevispina and Chloromonas nivalis, and cells of Scotiella polyptera were most frequently encountered. The following taxa are reported for the first time from snow and ice habitats in western North America: Anabaena variabilis, Actinotaenium cucurbita var. attenuatum, Synedra mazamaensis, S. tabúlala var.acuminata, Eunotia curvata var. curvata, Achnanthes flexella var. flexella, A. lapponica, Pinnularia hilseana var. hilseana, and Gomphonema acuminatum. In addition Cylindrocystis brebissonii f. cryophila is first reported from Alberta, and Raphidonema nivale and Chloromonas brevispina from California.
