compact usually dark-colored mass of hardened mycelium constituting a vegetative food-storage body in various true fungi; detaches when mature and can give rise to new growth
Later, the sphacelia convert into a hard dry sclerotium inside the husk of the floret.

At this stage, alkaloids and lipids accumulate in the sclerotium.

A sclerotium (plural sclerotia) is a compact mass of hardened fungal mycelium containing food reserves. One role of sclerotia is to survive environmental extremes. In some higher fungi such as ergot, sclerotia become detached and remain dormant until a favorable opportunity for growth. ...
Typhula is a genus of clavarioid fungi in the order Agaricales. Species of Typhula are saprotrophic, mostly decomposing leaves, twigs, and herbaceous material. Basidiocarps (fruit bodies) are club-shaped or narrowly cylindrical and are simple (not branched), often arising from sclerotia. ...
(Sclerotia) A compact mass of hyphae with or without host tissue, usually darkened rind, and capable of surviving under unfavorable environmental conditions.
(1) a firm, frequently rounded, mass of hyphae with or without the addition of host tissue, normally having no spores in or on it (Hawksworth et al., 1983). cf. bulbil, stroma. (2) in myxomycetes, the firm, resting condition of a plasmodium.
A mass of thick-walled cells formed by the vegetative hyphae that function as an organ of perennation.
Hard, resistant, multicellular resting body, usually with a differentiated cortex and medulla, that under favorable conditions can germinate to produce mycelium or sexual or asexual fruiting bodies. (Pl. sclerotia.) (22)
Hyphae closely interwoven and cemented together into a hard resistant body
