DETECTION OF RODLETS IN THE OUTER WALL REGION OF CONIDIOSPORES OF PHANEROCHAETE-CHRYSOSPORIUM

The surface morphology of the conidiospores of Phanerochaete chrysospo rium was investigated using freeze-etching. A multilayered structure c omposed 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 r odlet layer. During germination, the outer pellicle of the spore wall became fragmented and residual aggregates with rodlets were disseminat ed on the new conidiospore surface. The latter, as well as the germ tu be, was composed of fibrillar material.
