Arrhenia and Rimbachia, expanded generic concepts, and a reevaluation of Leptoglossum with emphasis on muscicolous North American taxa
The generic limits of Arrhenia Fries, Geotus Pil. & Svr., Leptoglossum Karsten, Leptotus Karst., Mniopetalum Donk & Singer, Phaeotellus Kühn. & Lam., Pleuromycenula Singer, and Rimbachia Patouillard are examined. Two genera, Arrhenia and Rimbachia, are recognized. Keys for the species in...
