W. Hantzschel 1975Bundled structures of flabellate or broomlike pattern, consisting or horizontal tunnels; proximally part of main tunnels unbranched, distal tunnels divide at acute angles into several free cylindrical tunnels showing delicate annulation beneath thin smooth “bark”; main branches may show structure similar to retrusive spreiten (absent in P. flabellum from Cincinnatian of USA); other “species” (e.g. P. pedum and P. flabellum) vary considerably in morphology from type species wich is also variable (e.g. falcate o featherstitch-like pattern of feeding tunnels); about 15 cm long in entirety; generally preserved as convex hyporeliefs in quartzites.
