Abstract

The identities of three species described in Verrucaria which have been regarded as lichenicolous fungi have been investigated. V. gemmifera Tayl., basionym of Tichothecium gemmiferum (Tayl.) Korb., a common lichenicolous fungus, is found to be based on discordant elements and the name rejected; it is suggested that T. gemmiferum auct. be used for this fungus pending a re-examination of the type of all other possible epithets. V. melaspora Tayl. proved to be a lichenized fungus belonging to the genus Polyblastia and the name P. melaspora (Tayl.) Zahlbr. should be used for the species currently called P. scotinospora (Nyl.) Hellb. Lastly, V. peripherica Tayl. was found to be a species of Pleospora subgen. Montagnula pathogenic to Pertusaria pseudocorallina and the new combination Pleospora peripherica (Tayl.) D. Hawksw. is made for this fungus.
