Stellate Chlamydospores and Thromboplerous Hyphae in the Mycelium of the Agaric <Emphasis Type="Italic">Lepista flaccida</Emphasis>

Development and morphology of mycelial chlamydospores and thromboplerous hyphae of the agaricoid Hymenomycete Lepista flaccida are described from laboratory cultures. The chlamydospore mother cell wall produces finger-like projections that become empty, stellate appendices of the mature spore. The fully developed wall is multi-layered. The cytoplasm contains two nuclei and one or two big oil drops. In thromboplerous hyphae, initial grains of the deuteroplasm condense into a solid, homogeneous mass.
