Close up of mold on a strawberry Penicillium mold growing on a clementine. A mold (US, PH) or mould (UK, CW) is one of the structures that certain fungi can form. The dust-like, colored appearance of molds is due to the formation of spores containing fungal secondary metabolites. The spores are the dispersal units of the fungi.
They have few septa and lack clamp connections. Fusiform skeletal hyphae are the second form of skeletal hyphae. Unlike typical skeletal hyphae these are swollen centrally and often exceedingly broad, hence giving the hypha a fusiform shape. Binding hyphae are thick-walled and frequent branched. Often they resemble deer antlers or defoliated ...
Light micrograph of the hyphae and spores of the human pathogen Aspergillus fumigatus. Mold health issues refer to the harmful health effects of molds ("moulds" in British English) and their mycotoxins. Molds are ubiquitous in the biosphere, and mold spores are a common component of household and
The dimorphic form of the species mainly exists and grows vegetatively as either a filamentous hyphae (mould form) or as spherical yeast (yeast form). [2] However, the organism is best known from the mould form which is characterised by the production of asexual reproductive state consisting of tall (up to 2 cm) needle-like sporangiophores with an apical swelling enclosed by a large sporangium ...
A common example of a zygomycete is black bread mold (Rhizopus stolonifer), a member of the Mucorales. It spreads over the surface of bread and other food sources, sending hyphae inward to absorb nutrients. In its asexual phase it develops bulbous black sporangia at the tips of upright hyphae, each containing hundreds of haploid spores.
It appears as a thin, superficial growth consisting of minute hyphae (fungal filaments) produced especially on living plants or organic matter such as wood, paper or leather. [1] [2] Both mold and mildew produce distinct offensive odours, and both have been identified as the cause of certain human ailments. [citation needed]

The English word fungus is directly adopted from the Latin fungus (mushroom), used in the writings of Horace and Pliny. [10] This in turn is derived from the Greek word sphongos (σφόγγος 'sponge'), which refers to the macroscopic structures and morphology of mushrooms and molds; [11] the root is also used in other languages, such as the German Schwamm ('sponge') and Schimmel ('mold').
