Bottom Line: The present study represents the second contribution in a series describing several novel species in different capnodealean genera defined in a previous study.Novelties on Eucalyptus from Australia include: Penidiella pseudotasmaniensis, P. tenuiramis, Phaeothecoidea intermedia, P. minutispora, Pseudocercospora tereticornis, Readeriella angustia, R. eucalyptigena, R. menaiensis, R. pseudocallista, R. tasmanica, Teratosphaeria alboconidia, T. complicata, T. majorizuluensis, T. miniata, T. profusa, Zasmidium aerohyalinosporum and Z. nabiacense, while Teratosphaeria xenocryptica is described on Eucalyptus from Chile.Novelties on other hosts include Phaeophleospora eugeniicola on Eugenia from Brazil, and Zasmidium nocoxi on twig litter from the USA.

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 based on their anamorph morphology. The present study represents the second contribution in a series describing several novel species in different capnodealean genera defined in a previous study. Novelties on Eucalyptus from Australia include: Penidiella pseudotasmaniensis, P. tenuiramis, Phaeothecoidea intermedia, P. minutispora, Pseudocercospora tereticornis, Readeriella angustia, R. eucalyptigena, R. menaiensis, R. pseudocallista, R. tasmanica, Teratosphaeria alboconidia, T. complicata, T. majorizuluensis, T. miniata, T. profusa, Zasmidium aerohyalinosporum and Z. nabiacense, while Teratosphaeria xenocryptica is described on Eucalyptus from Chile. Novelties on other hosts include Phaeophleospora eugeniicola on Eugenia from Brazil, and Zasmidium nocoxi on twig litter from the USA.

First of 1 000 equally most parsimonious trees obtained from a heuristic search with 100 random taxon additions of the Mycosphaerellaceae ITS sequence alignment using PAUP v4.0b10 (Swofford 2003). The scale bar shows 10 changes, and bootstrap support values 1 000 replicates are shown at the nodes. Thickened lines indicate the strict consensus branches and ex-type sequences are printed in bold face. The tree was rooted to Cladosporium colocasiae (GenBank accession AF393692) and Cladosporium sphaerospermum (GenBank accession AF455481).

The tree was rooted to Cladosporium colocasiae (GenBank accession AF393692) and Cladosporium sphaerospermum (GenBank accession AF455481).

Mentions: The manually adjusted ITS alignment for the Mycosphaerellaceae contained 93 taxa (including the two outgroup sequences) and, of the 547 characters used in the phylogenetic analysis, 268 were parsimony-informative, 30 were variable and parsimony-uninformative, and 249 were constant. Neighbour-joining analysis using the three substitution models on the sequence data yielded trees with identical topology and bootstrap values. For the parsimony analysis, only the first 1 000 equally most parsimonious trees were retained, the first of which is shown in Fig. 1 (TL = 1234, CI = 0.484, RI = 0.876, RC = 0.424).
