Detection of rodlets in the outer wall region of conidiospores of Phanerochaete chrysosporium.
The surface morphology of the conidiospores of Phanerochaete chrysosporium was investigated using freeze-etching. A multilayered structure composed of rodlets was detected. The rodlets had a diameter of 10.2 +/- 0.5 nm and were organised as long parallel fibres. Granules, smooth materials, and bark-like structures were found to cover part of this rodlet layer. During germination, the outer pellicle of the spore wall became fragmented and residual aggregates with rodlets were disseminated on the new conidiospore surface. The latter, as well as the germ tube, was composed of fibrillar material.
