Abstract

he Herbarium at West Virginia University has accumulated a collection of approximately ten thousand packets of mosses collected from West Virginia over a period of eighty years. Several taxonomic papers have been published about this group of plants, but none consolidates all the information concerning the classification and distribution of these mosses. Specimens dating back to 1891 were examined and checked, and nomenclatural changes were made. Field trips were conducted, and more specimens were collected. Forty-four families, one hundred and eleven genera, and two hundred seventy-three species have been catalogued. A brief description is given for each species as well as for the other categories included in this work. Keys were devised at family, generic, and specific levels. This dissertation updates the current list of species and summarizes the distribution record of each by county. It is probable that more species may be discovered, particularly in the less accessible parts of the range of these plants.
