An identification key for 20 common strand-forming indoor wood decay fungi is given. The key is based on observations of material from affected buildings and on wood samples that have been incubated in the laboratory. The key is with macro- and microscopic photographs.
In this article we review briefly the retrieval and analysis of molecular signals from the environment in relation to fungal diversity. Such molecular diversities have been assessed for terrestrial and aquatic systems, at various study levels, using PCR-based and nucleic acid hybridization-based techniques. The approaches adopted in some of these studies will be compared, including mention of the problems encountered, and discussed in broad terms detailing the identification of sequences representing fungal groups and their activities.
Fungi have now well and truly entered the genomic age. We currently know the complete DNA sequence for 18 fungal species and many more fungal genome sequencing projects are in progress. Whilst yeasts dominated the early genomic years, recently there has been a dramatic increase in filamentous fungal genome projects. The implications of this wealth of genetic information for mycologists worldwide is immense. In this review we summarise the background to fungal genome projects with an emphasis on the filamentous fungi. We discuss efforts to determine gene function and to compare genomes from different species. Since this is such a fast-moving field, useful web sites are listed that will enable the reader to keep up to date with developments.
