A sclerotium is a compact mass of hardened fungal mycelium, serving as a dormant structure for the fungus.
Sclerotia are like sleeping bags for fungi, helping them survive when conditions are not good for growing.
Examples:
The sclerotium is a hard ball of fungus.
The fungus makes a sclerotium to sleep in.
The sclerotium is like a bed for the fungus.
The little sclerotium is like a tiny house for the fungus.
The sclerotium is the fungus's safe place to hide.
The sclerotium is the fungus's secret hideout.
