What is Polyporus hurkillii Lloyd and how should it be spelled?

摘要

A study of the holotype (BPI) and isotype (SING) of Polyporus burkillii Lloyd shows that this material is homogeneous and does not belong to a species of the genus Polyporus as assumed by Ryvarden (1990) and Hattori (2001), but that Corner (1987) wascorrect in combining the name in Microporellus. At the specific level Corner however misinterpreted the taxon which should be included in M. clemensiae (Murrill) Ryvarden s.l. Further studies of Microporellus are needed and may show that this is a good species antedating other infudibuliform ones, especially M. inusitatus (Lloyd) Corner. The spelling of the name is discussed, the conclusion being that it should be corrected to Polyporus burkilliae. Microporellus burkillii (Lloyd) Corner ss. Comer is a good species that apparently lacks a name.
