. In 1899 Penzig described the species ''Colus javanicus'' based on a single specimen found on Java, and a year later Fischer amended the name of his original ''Colus fusiformis'' to ''Colus javanicus'', as he was not satisfied with the quality of his original description. Despite his doubts on the validity of his description, his original naming is both legitimate and has priority over ''C. javanicus''. In 1907,

described the new genus ''Pseudocolus'', and reduced several species to synonyms of ''Pseudocolus fusiformis''.

Description

The fruit body consists of a flaring, short stipe surmounted by unbranched columns that bear the gleba and are normally united at the apex, occasionally becoming free. The tissue of the receptacle has a tubular structure.

Species

Several species described as ''Pseudocolus'' have been reduced to synonymy with ''P. fusiformis'', while others are poorly known and have been seldom reported in the literature since their original descriptions. *''
