96 North American taxa sorted - Peck's revisited.

Charles Horton Peck described some 2700 species of North American fungi in the 19th and early 20th centuries. Among these were 31 species that he described as or that later authors recombined into . These 31 taxa have been analyzed morphologically and molecularly, as far as possible. For six of these species, lectotypes are designated. For twelve species, ITS sequences (some partial) were generated. Thirteen of the species analyzed are , as the genus is delimited today. Of these 13, nine are regarded as 'current', i.e. are names that should be accepted and used. Of the remaining four, three are synonymized with earlier Peck species and one with the generic type . Numerous species described from America are synonymized with some of Peck's species, such as , and ; Peck's , and are earlier names for , and , respectively. All three names were in current use and described from Europe. The 18 species that are not belong to a range of genera: , and ; three species that were not previously recombined into their respective genera are here recombined and one species, is synonymized with . Two taxa, that are not , remain unresolved. Sixty later taxa described from North America are revised and synonymized with Peck species and seven with , 36 of these supported by ITS (some partial) sequence data. Updates on two species, and , from Europe, are also given, and a lectotype and epitype selected for the latter.
