Penicillium growth can still occur indoors even if the relative humidity is low, as long as there is sufficient moisture available on a given surface. A British study determined that Aspergillus- and Penicillium-type spores were the most prevalent in the indoor air of residential properties, and exceeded outdoor levels. [14]
The surface of a Talaromyces (formerly Penicillium) marneffei colony. Image: James Gathany, CDC. Talaromyces marneffei, formerly called Penicillium marneffei, [1] was identified in 1956. [2] The organism is endemic to southeast Asia, where it is an important cause of opportunistic infections in those with HIV/AIDS-related immunodeficiency.
The precise constitution of the penicillin extracted depends on the species of Penicillium mould used and on the nutrient media used to culture the mould. [8] Fleming's original strain of Penicillium rubens produces principally penicillin F, named after Fleming. But penicillin F is unstable, difficult to isolate, and produced by the mould in ...
There may be no symptoms, [4] or talaromycosis may present with small painless skin lesions. [2] The head and neck are most often affected. [2] Other features include: fever, general discomfort, weight loss, cough, difficulty breathing, diarrhoea, abdominal pain, swelling of the spleen (splenomegaly), liver swelling (hepatomegaly), swollen lymph nodes (lymphadenopathy), [2] and anemia.
Characteristics of hyphae can be important in fungal classification. In basidiomycete taxonomy, hyphae that comprise the fruiting body can be identified as generative, skeletal, or binding hyphae. [12] Generative hyphae are relatively undifferentiated and can develop reproductive structures.
Penicillium chrysogenum (formerly known as Penicillium notatum) is a species of fungus in the genus Penicillium. It is common in temperate and subtropical regions and can be found on salted food products, [ 1 ] but it is mostly found in indoor environments, especially in damp or water-damaged buildings. [ 2 ]

Penicillium claviforme is a species of Penicillium within the phylum Ascomycota. It is found within the subgenus Terverticillium. It has a coremium-type morphology in the sexual structures, named for its resemblance to matchsticks. It is also known as Penicillium vulpinum; or synnema, meaning 'pillow', because of the closely appressed ...
