This number of Mycological Research News features confusion over the identity of Trichoderma strains used in biocontrol, and recent changes made to the classification of Coprinus. Attention is also drawn to the new address of the Executive Editor.
Thirteen papers are included in this issue, three with widespread implications for our understanding of particular groups of fungi resulting from a combination of molecular and anatomical studies: the European poroid Hymenochaetales, the lichenized ascomycete family Bacidiaceae, and the Exobasidiales/Microstromatales.
Other molecular studies examine Ephelis isolates on grasses, compare the β-tubulin gene of Melampsora lini with that of other fungi, establish anamorph connections and synonymy in Cordyceps sinensis, variation in Botrytis elliptica, and the identification of ectomycorrhizal fungi in Eucalyptus ecosystems.
Phosphorous uptake in Phanerochaete velutina in relation to soil water potential has been studied. In Metarhizium anisopliae, proteins formed by cold-active isolates are documented, and the effect of different UV-B wavelengths explored. Effects of heavy metals on two fungi from polluted and clean streams are compared, and fungal mycelium preserved in amber 15–45 Myr old from the Dominican Republic is described.
The following new scientific names are introduced: Volvocisporiaceae fam. nov.; Pseudoinonotus, and Volvocisporium gens. nov.; Fuscoporia torulosa (syn. Polyporus torulosus), F. wahlbergii (syn. Trametes wahlbergii), Mensularia hastifera (syn. Inonotus hastifera), M. nodulosa (syn. Polyporus nodulosus), Pseudoinonotus chrondromyelus (syn. Inonotus chondromyelus), P. dryadeus (syn.

This issue contains 15 original research papers. Fast-tracked is the description of a new and serious plant pathogen of Rhododendron and Viburnum, Phytophthora ramorum. Pistachio gummosis is found to be caused by two species of Phytophthora, one new to science. New molecular data confirm that the loculoascomycetes are not monophyletic, and show Chaetothyriomycetes to be a sister group of Eurotiomycetes, and that the Laboulbeniales warrant recognition as a separate ascomycete class (the Laboulbeniomycetes). Molecular studies on the hypogeous Arcangeliella borziana reveal a relationship to Lactarius sect. Russularia. A major study of Daldinia using a wide variety of biochemical and molecular methods is presented, and biometric studies on Pythium oospores demonstrate the efficacy of the approach in species separations.
The development of Sphaerotheca fusca on different melon cultivars is compared, Neotyphodium endophytes in grasses have been demonstrated inside vascular bundles for the first time, and the adhesion of conidia and germlings of Bipolaris sorokiana on solid surfaces investigated. In Agaricus bisporus the transcript levels of genes when stored is compared to that at harvest, and the behaviour of carbon-starved Penicillium chrysogenum cultures has been examined. The ability of citric and oxalic acids, and also culture filtrates of Aspergillus niger, to bind cobalt and zinc ions has been examined.
A remarkable new ascomycete discovered in Guyana, Pseudotulostoma volvata, resembles a gasteromycete, and a second species of Merimbla has been found in Mexico.
The following new scientific names are introduced: Pseudotulostoma gen. nov.; Merimbla humicoloides, Phytophthora pistaciae, P. ramorum, and Pseudotulostoma volvata spp. nov.
Evidence that the arbuscular mycorrhizal fungi are not closely
related to the zygomycetes, with which they have traditionally
been placed, has been growing. Fast tracked in this issue is a
paper comparing the SSU rRNA gene sequences in a wide
range of these and other fungi and formally establishing a new
phylum, Glomeromycota, and further three new orders for
these fungi (pp. 1413–1421).
This Mycological Research News features: Non-lichenized ascomycete lineages are derived from lichenized ancestors; and Changes in Coprinus questioned.
The issue contains the Presidential Address given by Stefan Buczacki in December 2000 on Berkeley's legacy, and 15 original research papers.
A protocol for protoplast preparation in Rhizoctonia solani is presented and transformation reported. Four papers describe molecular variability in different fungi; mycorrhizal Pisolithus strains in Australia; Mycosphaerella species on Eucalyptus; Phytophthora infestans; and Sphaeropsis sapinea.
The fungus causing anthracnose of tobacco is shown to be Colletotrichum destructivum, and the infection process followed.
One biotype of Trichoderma harzianum causing damage in Agaricus bisporus beds is tolerant of inhibitory bacteria. An extracellular mutanase from this same species may have applications in oral hygiene, and a protease from Cryptococcus neoformans has been found to be a metallopetidase.
Two papers focus on fungal development: sclerotial formation in Sclerotinia sclerotiorum may be triggered by oxidative stress; and rhizomorphs of Armillaria luteobulbina formed in aerial and submerged culture are compared.
The assemblages of endophytic fungi in different species of mangroves differ.
Systematic papers in this issue: revise the corticioid Sistotremateae in the Patagonian Andes; describe a new genus in the Kickxellales; and describe a new species of Chionosphaera.

This issue of Mycological Research News features the evolutionary origins of ryegrass endophytes, and implications of the cyclosporin experience for bioprospecting.
This month's Mycological Research includes 17 papers. The first demonstrates the successful and stable transformation of the genome in Fusarium circinatum using the Agrobacterium tumifaciens Ti plasmid. Molecular studies include ones on six species of Agaricus to elucidate their breeding systems, further research on the ascomycete order Agyriales, Alternaria alternata isolates associated with pistachio late blight, 16 species of Claviceps, the Entomophthora muscae complex, Hebeloma velutipes, Mycocalicium subtile, Ophiostoma piceae and O. quercus, genera in the Thelebolaceae, isolates identified as Trichoderma aureoviride, Tuber magnatum, and a Venturia associated with aspen blight.
Alternaria alternata, A. gaisen and A. longipes are shown to be distinct species, and the infection process of A. cirsinoxia on Canada thistle is documented.
