Scanning electron images of typical decay patterns in the collected sample material. Advanced soft rot decay (a, b sample 521 and 508 respectively), localized areas of brown rot decay (c sample 507), pockets where all cell wall layers were removed including the compound middle lamella (d sample 507). Benjamin W. Held generated the images.
