Strategy
If you lack the resistance required to neutralise the passive attack, it is best to let your pet attack the mold, attack it with a ranged weapon, or leave it alone. Molds will never move or actively attack you. You could also let your pet take it out but make sure they are strong enough to do so.
SLASH'EM
SLASH'EM features two new types of mold: the black mold and the disgusting mold. Their passive attack causes poison damage by way of spores; a nonbreathing character will be unaffected.
In both NetHack and SLASH'EM, the mold sometimes leaves a corpse. In SLASH'EM, the corpse might revive itself ("The yellow mold rises from the dead!"). Also in SLASH'EM, molds may grow on rotting corpses, taking the name of the corpse if it is named (which can result in some unexpected messages, especially in graveyards).
Encyclopedia entry
Mold, multicellular organism of the division Fungi, typified
by plant bodies composed of a network of cottony filaments.
The colors of molds are due to spores borne on the filaments.
Most molds are saprophytes. Some species (e.g., penicillium)
are used in making cheese and antibiotics.
