Calonectria metrosideri, a highly aggressive pathogen causing leaf blight, root...
Alfenas, R. F.; Pereira, O. L.; Ferreira, M. A.; Jorge, V. L.; Crous, P. W.; Alfenas, A. C.The genus Metrosideros includes several tree, shrub and vine species, native to the Pacific Islands. Seedlings from 25 seed lots of Metrosideros polymorpha and two seed lots of M. tremuloides with symptoms of root rot, stem girdling, wilting and round, purple leaf spots were observed in the Forestry Nursery at the Universidade Federal de Viçosa, Brazil. In the original disease site, seedling mortality reached u...
Novel fungi from an ancient niche: lachnoid and chalara-like fungi on ferns
Guatimosim, E.; Schwartsburd, P. B.; Crous, P. W.; Barreto, R. W.A survey was conducted in Brazil to collect fungi on ferns. Based on morphology and inferred phylogeny from DNA sequences of two loci, namely the internal transcribed spacer (ITS) regions and the large subunit nuclear ribosomal RNA gene (LSU), several species belonging to chalara-like genera and lachnoid fungi were recognized. Eighteen fungal isolates, collected from five host species, representing 10 different...

The Botryosphaeriaceae: genera and species known from culture
Phillips, A. J. L.; Alves, A.; Abdollahzadeh, J.; Slippers, B.; Wingfield, M. J.; Groenewald, J. Z.; Crous, P. W.In this paper we give an account of the genera and species in the Botryosphaeriaceae. We consider morphological characters alone as inadequate to define genera or identify species, given the confusion it has repeatedly introduced in the past, their variation during development, and inevitable overlap as representation grows. Thus it seems likely that all of the older taxa linked to the Botryosphaeriaceae, and f...
Preserving accuracy in GenBank
Bidartondo, M. I.; Bruns, T. D.; Blackwell, M.; Edwards, I.; Taylor, A. F. S.; Horton, T.; Zhang, N.; Koljalg, U.; May, G.; Kuyper, T. W.; Gilbert, G.GenBank, the public repository for nucleotide and protein sequences, is a critical resource for molecular biology, evolutionary biology, and ecology. While some attention has been drawn to sequence errors (1), common annotation errors also reduce the value of this database. In fact, for organisms such as fungi, which are notoriously difficult to identify, up to 20% of DNA sequence records may have erroneous lin...
Reconstructing the early evolution of Fungi using a six-gene phylogeny
James, T. Y.; Kauff, F.; Schoch, C. L.; Matheny, P. B.; Hofstetter, V.; Cox, C. J.; Celio, G.; Gueidan, C.; Fraker, E.; Miadlikowska, J.; Lumbsch, H. T.The ancestors of fungi are believed to be simple aquatic forms with flagellated spores, similar to members of the extant phylum Chytridiomycota (chytrids). Current classifications assume that chytrids form an early-diverging clade within the kingdom Fungi and imply a single loss of the spore flagellum, leading to the diversification of terrestrial fungi. Here we develop phylogenetic hypotheses for Fungi using d...
