Fig. 8

The processed µCT images of composites made of F. fomentarius and hemp shives. F. fomentarius is shown in yellow and the hemp shives in red. The subpanels A-B show enlargements of the marked regions. Hyphae attaching to the hemp shive substrate (A) and hyphae within xylem vessels (B) are depicted. Note that the outermost layer of the hemp shive appears thicker than the inner cell, which could potentially hint at an ongoing decomposition process of lignin and (hemi-)cellulose, which remains to be shown C
