The morphological characteristics of the fungus C11 were described in different stages of growth. It was observed that the fungal filaments (Fig. 1a) produce pigments in the presence of oxygen (Fig. 1b), which was accompanied by the release of a fragrant smell.The orange hue created by the isolate C11 confirms the production of secondary metabolites. The perithecial hairs appear and become more numerous and darker on the older cultures (Fig. 1c).
