sclerotium[sklə′rō·shəm] (microbiology) The hardened, resting or encysted condition of the plasmodium of Myxomycetes. (mycology) A hardened, resting mass of hyphae, usually black on the outside, from which fructifications may develop. Sclerotium in fungi, a dormant stage that occurs under unfavorable conditions. The sclerotium is a round or elongate body formed by the close intertwining of the hyphae of some ascomycetous, basidial, and imperfect fungi—for example, ergot, sclerotinia, Brazilian polyporous fungus, and monilia. The sclerotium usually ranges in size from a fraction of a millimeter to 2 cm. Some larger forms occur; for example, in the Brazilian polyporous fungus the sclerotium reaches 30 cm in diameter and 20 kg in weight. The cells of the outer part of the sclerotium are dark and thick-walled, whereas those of the interior are colorless and thin-walled. The sclerotium contains little water (5–10 percent) but is rich in nutritive substances. Under favorable conditions the sclerotium buds and forms fruiting bodies in ascomycetous and basidial fungi or mycelia with conidia in imperfect fungi. The sclerotium may remain viable for several years. The ergot sclerotium contains several alkaloids, including ergotoxine, ergometrine, and ergotamine, which are used medicinally as parturifacients and antihemorrhagics (to treat uterine hermorrhages). sclerotiumenUK
sclerotium [sklĕ-ro´she-um] a hard blackish mass formed by certain fungi, as ergot.scle·ro·ti·um, pl. scle·ro·ti·a (sklē-rō'shē-ŭm, -shē-ă), 1. In fungi, a variably sized resting body composed of a hardened mass of hyphae with or without host tissue, usually with a darkened rind, from which fruit bodies, stromata, conidiophores, or mycelia may develop. 2. The hardened resting condition of the plasmodium of Myxomycetes. sclerotium - a resting stage in many fungi. It takes the form of a ball of HYPHAE varying in size from a pinhead to a football, and usually has a hard, dark-coloured exterior coating. Fruiting bodies may be formed eventually from the sclerotium (either sexual or asexual) or a MYCELIUM may form. Normally the sclerotium does not contain spores.
- the firm resting condition of a myxomycete. see MYXOMYCOTA.
