Clementine in the context of "Linalool"

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. Not all fungi form molds. Some fungi form mushrooms or ascomata; others grow as single cells, and are called microfungi (for example, yeasts).

A large and taxonomically diverse number of fungal species form molds. The growth of hyphae results in discoloration and a fuzzy appearance, especially on food. The network of these tubular branching hyphae, called a mycelium, is considered a single organism. The hyphae are generally transparent, so the mycelium appears like very fine, fluffy white threads over the surface. Cross-walls (septa) may delimit connected compartments along the hyphae, each containing one or multiple, genetically identical nuclei. The dusty texture of many molds is caused by profuse production of asexual spores (conidia) formed by differentiation at the ends of hyphae. The mode of formation and shape of these spores is traditionally used to classify molds. Many of these spores are colored, making the fungus much more obvious to the human eye at this stage in its life-cycle.

Eau de Cologne (French: [o d(ə) kɔlɔɲ]; German: Kölnisch Wasser [ˈkœlnɪʃ ˈvasɐ]; meaning "Water from Cologne") or simply cologne is a perfume originating in Cologne, Germany. Originally mixed by Johann Maria Farina (Giovanni Maria Farina) in 1709, it has since come to be a generic term for scented formulations in typical concentration of 2–5% and also more depending upon its type of essential oils or a blend of extracts, alcohol, and water. In a base of dilute ethanol (70–90%), eau de cologne contains a mixture of citrus oils, including oils of lemon, orange, tangerine, clementine, bergamot, lime, grapefruit, blood orange, bitter orange, and neroli. It can also contain oils of lavender, rosemary, thyme, oregano, petitgrain (orange leaf), jasmine, olive, oleaster, and tobacco.

In contemporary American English usage, the term "cologne" has become a generic term for perfumes marketed toward men. It also may signify a less concentrated, more affordable, version of a popular perfume.
