Studies on Microstructures of Vegetative Mycelium in the Medicinal Mushrooms Hericlum ehnaceus (Bull.:Fr.)Pers. and Grifola frondosa (Dicks.:Fr.) S. F. Gray (Aphyllophoromycetideae)
ABSTRAKT
The morphological characteristics of fine hyphal structure, exocellular crystals, and asexual structures were investigated by light and electron scanning microscopy in pure dicaryotic cultures of Grifola frondosa (Dicks.:Fr.) S. F. Gray, and Hericium erinaceus (Bull.:Fr.) Pers. dicaryons and haploid strains. The hyphae of H. erinaceus were found to have numerous clamps with a hole at each septa, exocellullar crystals are of cubic or rectangular shape, and apical and intercallar chlamydospores form on the clamped conidiogenous hyphae. Haploid culture of H. erinaceus formed disintegrated arthroconidia by way of protoplast condensation. Medallion type clamps are characteristic for G. frondosa. Apical and intercallar chlamydospores developed on the dicaryotic mycelium, but they differ from those of H. erinaceus by formation on the clampless hyphae.
