Cottony Mildew

Mycelium Mildew A cottony mycelium grows over casing. When it contacts a mushroom, the mycelium soon envelopes the mushroom with a soft mildewy mycelium and causes a soft rot. It is also a parasite of wild mushrooms. The bodies of multicellular fungi usually consist of slender, cottony filaments called hyphae. A mass of hyphae is called a mycelium. The mycelium carries on all the life-maintaining processes of the organism, including sexual reproduction (in most species).
