Vermilacinia procera is a species in the subgenus Vermilacinia[REF] distinguished by the thallus divided into long slender cylindrical branches, irregularly blackened in patches from base to near apex, or only with black transverse band or spots.
Vermilacinia pumila is distinguished from V. procera by its relatively small thallus composed of stubby basal branches not more than 1 cm high [REF].
