Carnegie3, M.J. Wingfield4, J.Z. Groenewald1 Key words Abstract Recent phylogenetic studies based on multi-gene data have provided compelling evidence that the Mycosphaerellaceae and Teratosphaeriaceae represent numerous genera, many of which can be distinguished Mycosphaerella based on their anamorph morphology. The present study represents the second contribution in a series describing Penidiella several novel species in different capnodealean genera defined in a previous study. Novelties on Eucalyptus from Phaeophleospora Australia include: Penidiella pseudotasmaniensis, P. tenuiramis, Phaeothecoidea intermedia, P. minutispora, Pseu Phaeothecoidea docercospora tereticornis, Readeriella angustia, R. eucalyptigena, R. menaiensis, R. pseudocallista, R. tasmanica, Pseudocercospora Teratosphaeria alboconidia, T. complicata, T. majorizuluensis, T. miniata, T. profusa, Zasmidium aerohyalinosporum Readeriella and Z. nabiacense, while Teratosphaeria xenocryptica is described on Eucalyptus from Chile. Novelties on other hosts Teratosphaeria include Phaeophleospora eugeniicola on Eugenia from Brazil, and Zasmidium nocoxi on twig litter from the USA.

INTRODUCTION nine genera were defined in the Teratosphaeriaceae, namely Baudoinia, Capnobotryella, Catenulostroma, Devriesia, Peni The genus Mycosphaerella s.l. includes around 3 000 names diella, Phaeothecoidea, Readeriella, Staninwardia and Terato (Aptroot 2006), and together with its associated anamorph sphaeria. genera (especially Cercospora, Pseudocercospora, Septoria, The aim of this study was to apply the generic concepts estab- Ramularia, etc.) represents more than 10 000 species names lished in Crous et al. (2009b) for novel species collected from (Crous et al. 2000, 2001, 2004a, b, 2006a–c, 2007a–c, 2008a, various substrates. Thus species descriptions are linked to b, Crous & Braun 2003, Arzanlou et al. 2007, 2008). Although genera represented by phylogenetically defined clades (Crous Crous (1998) postulated that Mycosphaerella is polyphyletic, et al. 2009b), irrespective if the name applies to a sexual or initial phylogenetic trees based on ITS DNA sequence data asexual morph. The oldest generic name is given priority for suggested the contrary (Crous et al. 1999, 2000, 2001, Stewart each respective clade, with teleomorph species epithets hav- et al. 1999, Goodwin et al. 2001). However, adding additional ing priority over anamorph epithets if both are known for the loci later showed that Mycosphaerella is polyphyletic (Hunter et same holomorph. al. 2006, Crous et al. 2007a, b). Groups that have subsequently been separated from Mycosphaerella s.l. include Davidiella Materials AND METHODS species with Cladosporium anamorphs (Davidiellaceae) (Braun et al. 2003, Crous et al. 2007b, Schubert et al. 2007, Zalar Isolates et al. 2007, Dugan et al. 2008), and Schizothyrium species with Zygophiala anamorphs (Schizothyriaceae) (Batzer et al. Leaves with typical ‘Mycosphaerella’ leaf spots were chosen for study. Excised lesions were soaked in water for approximately 2008). 2 h, after which they were placed in the bottom of Petri dish In a recent study that considered generic boundaries in the lids, with the top half of the dish containing 2 % malt extract Teratosphaeriaceae and Mycosphaerellaceae (Capnodiales, agar (MEA; Oxoid, Hampshire, England) (Crous et al. 1991). Dothideomycetes; Schoch et al. 2006), Crous et al. (2009b) Ascospore germination patterns were examined after 24 h, and suggested to use a single generic name per phylogenetically single ascospore and conidial cultures established as described defined genus of fungi. In spite of the fact that not all clades by Crous (1998). Colonies were sub-cultured onto 2 % potato- could be defined, 12 genera were circumscribed in the Myco dextrose agar (PDA), synthetic nutrient-poor agar (SNA), MEA, sphaerellaceae, representing Cercospora, Cercosporella, Dothi and oatmeal agar (OA) (Crous et al. 2009c), and incubated stroma, Lecanosticta, Phaeophleospora, Polythrincium, Pseudo under continuous near-ultraviolet light at 25 °C to promote cercospora, Ramularia, Ramulispora, Septoria, Sonderhenia sporulation.
