streaks on the basal or upper regions of the stem and on the caps of developing primordia. These
spots become grayish colored from spore production. Afflicted mushrooms offen bend towards the
side that is infected. If the mushrooms do develop at all, they are typically tilted to one side or the
other. Verticillium attacks developing fruitbodies—the more severely infected are grossly malformed, especially young primordia which are turned into sclerotia-like balls of amorphous whitish
mycelia. More mature but diseased mushrooms have a deformed pileus, sometimes with a "hair
lip", and frequently with a downy grayish mycelium over the cap. The stem can be covered with a
downy mycelium and often vertically splits, roughly resembling a peeled banana. The cap becomes
disproportionately small relative to the fatter than normal stem. The overall texture of the mushroom
is dry and leathery.
When this mold attacks Psilocybe cubensis, there are several additional characters worthy of
note. Parasitized P. cubensis caps frequently become plane at an early stage. The stem becomes
swollen and hollow, narrowing radically towards the apex. Only in an extremely humid environment
does a downy mildew develop over the cap and stem surface. The "Verficillium spots" so commonly reported by growers of Agaricus, a white mushroom, are more accurately called "Verticillium
streaks" on P. cubensis, a mushroom with a brownish cap and a whitish stem.
