Phylogeny and taxonomy of the Ophiostoma piceae complex and the Dutch elm disease fungi
Limitation fragment length polymorphisms of the ITS region are shown to be a convenient diagnostic tool for delimiting these species within the Ophiostoma piceae complex.
Phylogenetic analysis places the Phialophora-like anamorph genus Cadophora in the Helotiales
Using ITS and 28S (LSU) rDNA sequences, members of the genus Cadophora are shown to be anamorphs of the Helotiales (discomycetes) and distinct from the morphologically similar anamorph genus…
Self-fertility and uni-directional mating-type switching in Ceratocystis coerulescens, a filamentous ascomycete
Individual perithecia from selfings of most Ceratocystis species produce both self-fertile and self-sterile progeny, apparently due to uni-directional mating- type switching, and it is hypothesized that the switch in mating-type during selfing is associated with a deletion of the MAT-2 gene.
Three genera in the Ceratocystidaceae are the respective symbionts of three independent lineages of ambrosia beetles with large, complex mycangia.
Phylogenetic and taxonomic evaluation of Chalara, Chalaropsis, and Thielaviopsis anamorphs associated with Ceratocystis.
Parsimony analysis of sequences of the internal transcribed spacer region of the nuclear rDNA and partial sequences of the large subunit (LSU) place four anamorphic Chalara species as a monophyletic…
New Ceratocystis species associated with rapid death of Metrosideros polymorpha in Hawai’i
Morphology and interfertility tests support the delineation of these two new species of Ceratocystis and pathogenicity tests show that both species are aggressive pathogens on seedlings of M. polymorpha.
Wood-Destroying Soft Rot Fungi in the Historic Expedition Huts of Antarctica

The presence of Cadophora species, but only limited decay, suggests there is no immediate threat to the structural integrity of the huts, however, these fungi are widely found in wood from the historic huts and have the capacity to cause extensive soft rot if conditions that are more conducive to decay become common.
Survey of potential sapstain fungi on Pinus radiata in New Zealand
A nationwide survey of New Zealand sapstain fungi on Pinus radiata was undertaken between 1996 and 1998 with collections of 1958 samples of material from 869 sites in the North and South Islands, where S. sapinea was isolated from all material sampled including collections from the forest floor as well as from logs and timber.
Genetic relationships among Leptographium terebrantis and the mycangial fungi of three western Dendroctonus bark beetles
Morphology, mitochondrial DNA (mtDNA) restriction fragment polymorphisms (RFLPs) and nuclear DNA (nDNA) fingerprinting were used to clarify relationships among the morphologically similar Ophiostoma…
Genetic Bottlenecks for Two Populations of Ceratocystis fimbriata on Sweet Potato and Pomegranate in China.
Isolates from sweet potato and pomegranate in China were interfertile with tester strains of C. fimbriata, confirming that the causes of the two epidemics in China belong to a single biological species.
