Light Microcopy : (a) Wood-decay fungi such as the white-rot Physisporinus vitreus exploit a wood tissue by forming a root-like network (mycelium) consisting of filaments (hyphae) with a diameter of approximately 2 μm. This hyphal network is visible under the light microscope. Specimens are usually cut into thin section as shown in (b), in order to analyze the distribution of mycelium in the wood by a sequence of light microscopy pictures. (c) These single pictures are stitched together and form a mosaic picture covering a whole thin section. (d) Using digital image processing one can identify the fungus and analyze mycelium’s morphology in a whole sample. The principal directions of wood are usually termed as longitudinal, radial and tangential, denoted by the letters L, R and T.
