description Ahnfeltiopsis devoniensis Overview
Ahnfeltiopsis devoniensis is a small cartilaginous red alga in the family Phyllophoraceae, also known in older literature as Gymnogongrus devoniensis. It grows from a disk-like holdfast on rocky lower-intertidal and shallow-subtidal shores, forming a flattened frond with regular forked branching. The branches have parallel sides and internal cystocarps, features that help distinguish it from the similar Gymnogongrus crenulatus; the name reflects its historical association with Devon, England.
