Grebeniuk isolated R. stolonifer from hemp stems. In an inoculation experiment, I quickly rotted some damp marijuana with a colony of R. stolonifer found growing on bread. P. italicum perfumes a lavender bouquet, while A. flavus smells like a locker room. Clostridium bacteria stink like carrion. Infested marijuana often darkens in color and becomes crumbly.
Anaerobic bacteria turn marijuana into brown slime.
Marijuana undergoing rapid decay may feel warm to touch. Tufts of fungi are often visible in mold material. In marijuana stored in darkness, strands look white to light grey. Exposed to light, storage molds spawn millions of colored spores in velvet clumps. A slight tap sends these spores into great billowing clouds.
