There are three types of fungal wood rot: brown, white, and soft rot . Further terms are either older names (e.g., destruction rot = brown rot), specifications (red rot = white rot by Heterobasidion annosum) or terms used in practice ( marble rot = white rot with black demarcation lines) or false names (blue rot = blue stain). According to the classical school of thought a fungal species causes only one type of decay, and species causing different rots shall not be grouped in the same genus [e.g.: Lentinus lepideus: brown rot ; Lentinula (in former times Lentinus) edodes: white rot]. Regarding the delineation between the three decay types, there are, however, exceptions: The brown-rot fungus Coniophora puteana produced cavities to be typical of soft-rot fungi and erosion and thinning of the cell wall to be charac-teristic of white-rot fungi (Kleist and Schmitt 2001; Lee et al. 2004). Fistulina hepatica revealed the soft-rot mode in cell walls rich in syringyl lignin,
