A comparison of the cotype material of Coriolus currani Murr., with 
authentically named specimens of Polystictus murinus Lév., discloses their 
identity and the necessity of reducing Murrill’s species to a synonym of 
the latter. ‘

This species is exceedingly common throughout the Archipelago. Some 
slight variation is found in the upper surface, which may be velvety or 
nearly lack the short tomentum, and in the texture, which may be thin 
and flexible or somewhat rigid. These differences, however, are not so 
great but that all forms may be found in a single collection when repre- 
sented by a number of specimens. From an observation of material col- 
lected in quantity and from a number of localities there can be no doubt
