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

/scle·ro·ti·um/ (sklĕ-ro´she-um) a structure formed by fungi and certain protozoa in response to adverse environmental conditions, which will germinate under favorable conditions; in fungi, it is a hard mass of intertwined mycelia, usually with pigmented walls, and in protozoa it is a multinucleated hard cyst into which the plasmodium divides.

sclerotium

  1. 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.
  2. the firm resting condition of a myxomycete. see MYXOMYCOTA.

sclerotium

pl. sclerotia; a hard blackish mass of mycelia formed during the resting phase by certain fungi, as Claviceps purpurea.
