Summary Within the genus Coniophora, C. puteana and the less common species C. marmorata, C. arida and C. olivacea form a group of domestic brown-rot fungi (“cellar fungi”), which cause considerable decay in the woodwork of buildings. The fungi are difficult to distinguish by their fruit bodies. Traditional methods fail to identify species in a pure culture. Also with regard to decay of wood in use, the basidiomes rarely develop, and the surface mycelium on wood is sparse except for the fine dark strands. Thus, molecular techniques were applied to obtain a reliable method for differentiation and detection and to aquire a greater knowledge of the domestic Coniophora species. Isolates obtained from decayed wood and from culture collections and identified as domestic Coniophora species were used. The internal transcribed spacer (ITS) of the ribosomal DNA was amplified by polymerase chain reaction, sequenced and restricted by the endonuclease TaqI. The ITS sequences characteristic of C. puteana, C. arida, C. marmorata and C. olivacea were obtained and entered into the international databases. The sequence size ranges from 525 to 729 bp. The data supplement our collection of ITS sequences from domestic wood decay fungi built for the characterization of mycelium in culture. Most isolates belong to C. puteana and some to C. arida, C. marmorata and C. olivacea. Two other isolates belong to a further Coniophora species close to C. olivacea. Obviously, at least five Coniophora species occur within European buildings. Many of the isolates were not correctly identified. Consequently, the traditional characterization methods used, viz., growth rate, temperature influence and wood weight loss, were less suitable for the differentiation of Coniophora species as formerly anticipated.

Service life planning with timber requires reliable models for quantifying the effects of exposure-related parameters and the material-inherent resistance of wood against biotic agents. The Meyer-Veltrup model was the first attempt to account for inherent protective properties and the wetting ability of wood to quantify resistance of wood in a quantitative manner. Based on test data on brown, white, and soft rot as well as moisture dynamics, the decay rates of different untreated wood species were predicted relative to the reference species of Norway spruce (Picea abies). The present study aimed to validate and optimize the resistance model for a wider range of wood species including very durable species, thermally and chemically modified wood, and preservative treated wood. The general model structure was shown to also be suitable for highly durable materials, but previously defined maximum thresholds had to be adjusted (i.e., maximum values of factors accounting for wetting ability and inherent protective properties) to 18 instead of 5 compared to Norway spruce. As expected, both the enlarged span in durability and the use of numerous and partly very divergent data sources (i.e., test methods, test locations, and types of data presentation) led to a decrease in the predictive power of the model compared to the original. In addition to the need to enlarge the database quantity and improve its quality, in particular for treated wood, it might be advantageous to use separate models for untreated and treated wood as long as the effect of additional impact variables (e.g., treatment quality) can be accounted for. Nevertheless, the adapted Meyer-Veltrup model will serve as an instrument to quantify material resistance for a wide range of wood-based materials as an input for comprehensive service life prediction software.
