Paecilomyces variotii, also known by the name Byssochlamys spectabilis for the sexual state, is a common environmental mold from the Phylum Ascomycota (Family Thermoascaceae). [1] It is widespread in the environment and can be found in composts, soils and wood, [ 2 ] [ 3 ] [ 4 ] as well es a common environmental contaminant in indoor air and ...
An ascus (from Ancient Greek ἀσκός (askós) 'skin bag, wineskin'; pl.: asci) [1] is the sexual spore-bearing cell produced in ascomycete fungi. Each ascus usually contains eight ascospores (or octad), produced by meiosis followed, in most species, by a mitotic cell division.
[5] [6] The genus name "Lomentospora" referred to the shape of the apex of the spore-bearing cell, which the authors interpreted to be a rachis resembling a bean pod of the sort constricted at each seed. The species epithet "prolificans" derived from the prolific nature of the mold's sporulation.
The plasmodia abandon their nutrient intake and crawl, attracted by light – a positive phototaxis – towards a dry, light area, to get an optimal spread of the spores. Once the fructification begins, it cannot be stopped. If disturbances occur, malformed spore-bearing fruit bodies are often produced. [11] [19] Woodlouse with myxogastria spores
A large spore that increases notably in size, but does not divide. Upon being inhalted in the lungs of humans and animals, can cause adiaspiromycosis disease. From Gr. a-, without, dia, separating. [9] adnate . attached, adherent. Adhering; attached to the stipe throughout its width, esp. of lamellae or tubes. Compare with free. [10] aero ...
The spore-bearing sporangiophores of Phycomyces are very sensitive to different environmental signals including light, gravity, wind, chemicals and adjacent objects. They exhibit phototropic growth: most Phycomyces research has focused on sporangiophore photobiology , such as phototropism and photomecism ('light growth response').
Fruiting bodies have a short stalk from which arises a spore-bearing structure (the receptaculum) of 5–8 arched arms. These arms, initially joined at the top, disconnect and curve irregularly to expose the inner surface of each arm, which is covered with green spore-containing gleba. Spores are 3–4 × 1–1.5 μm.

The basidia (spore-bearing cells) are club shaped and four-spored, with dimensions of 18–22 by 5–5.6 μm. H. rutilans has a monomitic hyphal system, containing only generative hyphae with clamp connections.
