scle·ro·ti·um (sklə-roґshe-əm) [L. sclerotica hard] 1. in fungi, a hard mass of intertwined mycelia, usually with pigmented walls resistant to adverse environmental conditions; it will germinate to produce new hyphae under favorable conditions or in response to a chemical stimulus from a prospective host. 2. in certain protozoa, a multinucleate hard cyst into which the plasmodium divides in response to adverse environmental conditions, such as desiccation; sclerotia will germinate and fuse together to produce a new plasmodium under favorable conditions.
