It is also toxic to mammals, as proven by rodent studies: “At relatively high doses, patulin is acutely toxic in mice and rats, causing gastrointestinal lesions, distension and haemorrhage in the stomach and small intestine… LD50 values (lethal dose) of 20-100 mg/kg bodyweight have been reported for patulin administered orally to mice and rats.” (. The spores of this mould are found everywhere in the air and soil. For such detailed information, you will still need to have a sample sent away to a lab. The genus was first identified in scientific literature by Johann Heinrich Friedrich Link in his 1809 work Observationes in ordines plantarum naturale.  Named after the spores’ likeness to a paintbrush (from the Latin penicillus), various species of Penicillium are found around the world, though they generally prefer cool to moderate climates.

When dealing with spore trap lab results, you will often see these types listed together in groups such as Aspergillus / Penicillium, Asp/Pen, or Pen/Asp.Visually, spores of these genera are so similar that analysts can not differentiate them, so they are reported together. The mycelial cake of Penicillium chrysogenum , when dried and specially processed, has been found to serve as a source of protein in place of soybean meal in the diet of experimental mice. Some species produce mycotoxins which are known carcinogens. Penicillium chrysogenum is a widely studied species of Penicillium and is sometimes known as P. notatum, P. meleagrinum,or P. cyaneofulvum (3) though occasionally they are not synonymous.
