Fungal Diversity Taxonomic revision of the genus Cladosporium s.l. 4. Species reallocated to Asperisporium, Dischloridium, Fusicladium, Passalora, Pseudoasperisporium and Stenella Konstanze Schubert * and Uwe Braun Martin-Luther-Universität, FB. Biologie, Institut für Geobotanik und Botanischer Garten, Neuwerk 21, D-06099 Halle (Saale), Germany Schubert, K. and Braun, U. (2005). Taxonomic revision of the genus Cladosporium s.l. 4. Species reallocated to Asperisporium, Dischloridium, Fusicladium, Passalora, Pseudo- asperisporium and Stenella. Fungal Diversity 20: 187-208. Cladosporium caesalpiniae (nom. inval.) is validated as Fusicladium caesalpiniae, the new combinations Dischloridium gloeosporioides, D. livistonae, Fusicladium aromaticum, F. myrticola, Passalora gynoxidicola, Pseudoasperisporium puccinioides and Stenella lonicericola are introduced and detailed descriptions, illustrations and comments are provided. Cladosporium sphaeroideum is reduced to synonymy with Passalora graminis. The herbarium name Cladosporium pygmaeum proved to be conspecific with Asperisporium minutulum and Cladosporium pelliculosum is identical with Passalora lobeliae-cardinalis. Gloeosporium cladosporioides is reduced to synonym with Colletotrichum gloeosporioides s.l. Key words: hyphomycetes, new combinations and species, taxonomy. Introduction Based on molecular sequence data as well as re-examinations and reassessments of morphological characters of the conidiogenous loci and conidial hila (David, 1997; Braun et al., 2003), the genus Cladosporium Link has been confined to anamorphs of the ascomycetous genus Davidiella Crous & U. Braun (= Mycosphaerella Johanson p.p.), characterized by having pigmented conidiophores with coronate conidiogenous loci, i.e. composed of a central convex dome surrounded by a raised periclinal rim, and pigmented conidia formed in acropetal chains. A recently published Cladosporium checklist contains 772 names (Dugan et al., 2004), showing the urgent need for a comprehensive revision of the heterogeneous genus Cladosporium s.l. During the course of re-examinations of type material and additional collections referred to this genus, numerous species proved to be non-congeneric with Cladosporium s.s. so that they have to be reallocated to other genera. * Corresponding author: K.
