García-Soto &amp; Lopez-Bautista (2018) presented molecular-based evidence to propose the merger of Bryothamnion within Alsidium. These two species had been assigned to that genus in the past, and so those two names are reinstated.</p> </div>	https://treatment.plazi.org/id/03D1182DFFB7B11DFF26FCAB6321992F	Public Domain	No known copyright restrictions apply.
