[as Rhytidiadelphus calvescens]
Southeastern Alaska Distribution: Known from Mt. Roberts near Juneau (Persson and Gjaerevoll, 1961).
Habitat: Usuually among grasses and forbs in meadows, especially in mountainous regions.
Comments: Sometimes with sporophytes. This species is very poorly understood in North America, and has variously been treated as synonymous with Rhytidiadelphus squarrosus, or as subspecific taxa of that species. I have not distinguished it from R. squarrosus, so all of my material has been placed under the latter species.
