The genus Phaeomegaceros is characterized by yellow spores with distal fovea, stomata in the capsule wall, pyrenoidless plastids and typically monandrous androecia. Based on morphology and sequence data we transfer Phaeoceros squamuligerus (Spruce) Hässel to the genus Phaeomegaceros and describe a new subspecies, P. squamuliger subsp. hasselii, from Osorno, Chile. The distinguishing features of this new subspecies are: a smooth broad thallus, robust sporophytes (up to 0.7 mm thick in transverse section), large yellow spores (45–60 μm in diameter) with a central deep depression and regular ridges around the periphery of the distal face. The main differences between this subspecies and the typical P. squamuliger is the absence of dorsal outgrowths and the presence of pronounced ridges surrounding the central depression on the distal face of the spores. Morphological comparisons with other species of the genus are made. Based on current data, Phaeoceros chiloensis and Phaeoceros foveatus are also transferred to Phaeomegaceros.
