Diagnosis. - "Rhabdosome flabellate, straight primary
stipe, closely alternating lateral branching of
secondary stipes, higher order branching as
dichotomous bifurcations. Stipes are thick
throughout but taper abruptly at distal ends.
Dissepiments are rarely observed and occur only
between third- and fourth-order stipes. Sicula and
thecae unknown." Erdtmann & Adams 1975, pp.
342-343.
