Many fungi are pathogenic on plants and cause significant damage in agriculture and forestry. They are also part of the natural ecosystem and may play a role in regulating plant numbers/density. Morphological identification and analysis of plant pathogenic fungi, while important, is often hampered by the scarcity of discriminatory taxonomic characters and the endophytic or inconspicuous nature of these fungi. Molecular (DNA sequence) data for plant pathogenic fungi have emerged as key information for diagnostic and classification studies, although hampered in part by non-standard laboratory practices and analytical methods. To facilitate current and future research, this study provides phylogenetic synopses for 25 groups of plant pathogenic fungi in the Ascomycota, Basidiomycota, Mucormycotina (Fungi), and Oomycota, using recent molecular data, up-to-date names, and the latest taxonomic insights. Lineagespecific laboratory protocols together with advice on their application, as well as general observations, are also provided. We hope to maintain updated backbone trees of these fungal lineages over time and to publish them jointly as new data emerge. Researchers of plant pathogenic fungi not covered by the present study are invited to join this future effort. Bipolaris, Botryosphaeriaceae,

A severe rust disease has caused extensive damage to plantation grown Acacia mearnsii trees in the KwaZuluNatal Province of South Africa since 2013. The symptoms are characterized by leaf spots, petiole and rachis deformation, defoliation, gummosis, stunting of affected trees and dieback of seedlings. The cause of this new disease was identified using a combined morphological and DNA sequence approach. Based on morphology, the rust fungus was identified as a species of Uromycladium. It formed powdery, brown telia on petioles, stems, leaves, seedpods and trunks of affected trees. The teliospores were two per pedicel and either lacked or had a collapsed sterile vesicle. Sequence data and morphology showed that the collections from South Africa were conspecific, however telia were not produced in all provinces. Uromycladium acaciae is the most suitable name for this rust fungus, based on morphology and phylogenetic analyses of the internal transcribed spacer and large subunit regions of ribosomal DNA. The rust was first identified as U. alpinum in 1988, from minor symptoms on the leaflets caused by its uredinial stage on A. mearnsii in South Africa. It has now become a threat to plantations of A. mearnsii, with an altered life cycle and increased disease severity.

Rust (Puccinia psidii) recorded in Indonesia poses a threat to forests and forestry in South-East Asia

Over the past decade, Puccinia psidii, which causes rust on species of Myrtaceae, has spread rapidly to new areas and is now widespread. Quarantine has done little to prevent its movement through America, the Pacific, Africa, and in this report, SouthEast Asia. Puccinia psidii is reported for the first time from Indonesia on two genera of Myrtaceae, namely Eucalyptus and Melaleuca. The identity was confirmed by morphology, a molecular barcode comparison to an epitype specimen, and with a molecular phylogenetic approach. Comparison of seven microsatellite markers revealed that the genotype of the rust in Indonesia is the same as that found in Australia. The potential impacts of P. psidii in South-East Asia to the natural environment and plantation forestry are discussed in light of this first report from the region.
