context_page_description: Cantharellus lateritius, commonly known as the smooth chanterelle, is a species of edible fungus in the mushroom family Cantharellaceae. An ectomycorrhizal species, it is found in Asia, Africa, and North America. The species has a complex taxonomic history, and has undergone several name changes since its first description by American mycologist Lewis David de Schweinitz in 1822. The fruit bodies of the fungus are brightly colored yellow to orange, and usually highly conspicuous against the soil in which they are found. At maturity, the mushroom resembles a filled funnel with the spore-bearing surface along the sloping outer sides. The texture of the fertile undersurface of the caps is a distinguishing characteristic of the species: unlike the well-known golden chanterelle, the hymenium of C. lateritius is much smoother. Chemical analysis has revealed the presence of several carotenoid compounds in the fruit bodies.
context_section_description: The caps of the C. lateritius fruiting bodies typically range between 2 to 9 cm (0.8 to 3.5 in) in diameter, with a flattened to somewhat funnel-shaped top surface and a wavy margin. The cap surface is dry, slightly tomentose (covered with a layer of fine hairs), and a deep and bright orange-yellow color, with older specimens fading to more yellow in age; the distinctive margins of the cap are a paler yellow, and typically curve downward in young specimens. Fruiting bodies can reach a height of 12 cm (4.7 in). The hymenophore (the spore-bearing surface) is initially smooth and without wrinkles, but gradually develops channels or ridges, and what appear to be very shallow gills that are vein-like, and less than 1 mm wide. The color is pale yellow, and is continuous with the surface of the stem. The stem is rather plump and stout, 1.5 to 4.5 cm (0.6 to 1.8 in) long and 0.5 to 1.7 cm (0.2 to 0.7 in) thick, more or less cylindrical, tapering downwards towards the base. Internally, the stems are either stuffed (filled with cotton-like mycelia) or solid. Rarely, fruiting bodies may be clumped together with stems conjoined at the base; in these cases there are usually no more than three fused stems. The flesh is solid to partly hollow (sometimes due to insect larvae), with a pale yellow color; it is 0.5 to 0.9 cm (0.2 to 0.4 in) thick.
  The spores are smooth, with a roughly ellipsoid shape, and have typical dimensions of 7–7.5 by 4.5–5 µm. In deposit, such as in a spore print, the spores are light yellow orange, while under the microscope they are a very pale yellowish. The spore bearing cells—the basidia—are 75–80 by 7–9 µm, 4-5-6-spored, slightly club-shaped, and with a distinctly thickened wall at the base. Clamp connections (short branches connecting one cell to the previous cell to allow passage of the products of nuclear division) are present in the hyphae of all parts of the fruiting body.
