This issue of Mycological Research News features: CBS centenary: collect, study and preserve; In this issue; The origins of Saccharomyces cerevisiae; and Diversity of fungal laccase gene sequences in salt marshes.

A review of aspects of fungal genetic resource collections and their role in the genomic age precedes papers on relationships within Pythium and the Coronophorales using molecular phylogenetic approaches. Diplodia pinea and D. scrobiculata on pines in North America are reassessed. The polygalacturonase encoding gene of Rhizopus oryzae is characterized, the kinetics of selenite uptake in Saccharomyces cerevisae are described, viability tests for Rhinosporidium seeberi endospores are assessed, and aspects of the detection of the isoepoxydon dehydrogenase gene involved in patulin biosynthesis are explored. Other papers consider fire and the availability of hypogeous fungi as animal food in Australia, interactions between scarce tooth fungi and others, Termitomyces species consumed in China, red-capped species of Russula sect. Xerampelina, and rapid detection of Mycosphaerella species on Eucalyptus.

The following new scientific names are introduced: Chaetosphaerellaceae and Scortechniaceae fams. nov.; Bertia tropicalis, Lasiobertia portoricensis, Nitschkia meniscoidea, and Termitomyces bulborhizus spp. nov.; and B. multiseptata (syn. B. moriformis var. multiseptata) comb. nov.
