Identification
The thallus of this red seaweed is relatively thick with a vaguely circular shape and irregular lobes. The tiny holdfast measures only 1 mm wide and is usually attached to the blade directly, though occasionally the blade may be connected via a short stipe. It grows to 18 cm tall, and tends to lay across the substrate instead of growing upwards.
Habitat & Range
This species has been recorded growing on rock in the low intertidal and subtidal; it is also occasionally found growing on marine invertebrates. It has been recorded as Salishia firma at multiple locations along the coast of British Columbia, and one location in California. Before the Salishia genus was defined (and other genera, including Pugetia, were redefined in the same study), it was recorded as Pugetia firma in BC and California, and as the synonym Callophyllis firma from Alaska to California (due to the reevaluation of genera these records may not be of S. firma as it is now defined.
Similar Species
Similar species reviewed or redescribed in the same study include Salishia sanguinea and Pugetia species. See Clarkson and Saunders (2012) for details.
