In this paper a microscopy study was presented with focus on the cellulolytic fungi action on cotton fibers physical aspect. Qualitative and quantitative analysis was accomplished based on samples of textile material used as support for Chaetomium globosum and Phanerochaete chrysosporium fungi was carried out. Fiber size and mesh aperture changes were evaluated evidencing more invasive attack of P. chrysosporium compared to C. globosum microorganism. Fiber size changing with 6 to 19% for C. globosum was revealed while for P. chrysosporium the changes ranged between 20 and 39% and also fibers were broken down. The microscope investigation could be of interest for further study of cotton textile resistance to environmental mildew.
