Abstract
Six species of mycosphaerellaceous fungi on ferns from mainland China and Taiwan island are investigated by morphology and analysis of the internal transcribed spacer of the ribosomal RNA genes. Two species of Pseudocercospora from spots on living leaves of ferns (Polypodiales) in Taiwan are newly described. One species found on Microlepia spp. (Dennstaedtiaceae) differs from Ps. lonchitidis, the single other species considered as occurring on members of the Dennstaedtiaceae, by narrower conidiophores and conidia. Another species found on Tectaria harlandii (Tectariaceae) differs from the majority of Pseudocercospora species by the internal hyphae which are often thick-walled and/or covered by conspicuous incrustations, and from the single other species known from the same host family, Ps. helminthostachydis, by narrower conidiophores and conidia. Mycosphaerella gleicheniae, Periconiella lygodii, Ps. lygodii, and Zasmidium dicranopteridis are recorded for the first time from mainland China and Ps. pteridicola from Taiwan. Based on new collections from both regions and the type, Pseudocercospora lygodii is transferred to Passalora.
