While it is relatively easy to identify a sample mushroom as belonging to this genus, it is a significant challenge to distinguish member species of Russula. This task often requires microscopic characteristics, and subtle subjective distinctions, such as the difference between a mild to bitter and a mild to acrid flavor.
Developed by Julius Schäffer to help with the identification of Agaricus species. A positive reaction of Schaeffer's test, which uses the reaction of aniline and nitric acid on the surface of the mushroom, is indicated by an orange to red color; it is characteristic of species in the section Flavescentes. The compounds responsible for the ...
Heliomeris longifolia - longleaf false goldeneye - Sonora, Chihuahua, Durango, Jalisco, San Luis Potosí, Michoacán, Chiapas, Arizona, New Mexico, Texas, Colorado, Utah, Nevada; Heliomeris multiflora - showy goldeneye - from San Luis Potosí + southern California to Montana; Heliomeris obscura - Puebla, Oaxaca
Baorangia bicolor, also known as the two-colored bolete or red and yellow bolete after its two-tone coloring scheme, is a species of fungus in the genus Baorangia.. Its fruit body, the mushroom, is classed as medium or large in size, which helps distinguish it from the many similar appearing species that have a smaller stature.
The species was first described scientifically by American mycologist Howard James Banker in 1913. [2] Italian Pier Andrea Saccardo placed the species in the genus Hydnum in 1925, [3] while Walter Henry Snell and Esther Amelia Dick placed it in Calodon in 1956; [4] Hydnum peckii (Banker) Sacc. and Calodon peckii Snell & E.A. Dick are synonyms of Hydnellum peckii.
Lactarius is a genus of mushroom-producing, ectomycorrhizal fungi, containing several edible species. The species of the genus, commonly known as milk-caps, are characterized by the milky fluid ("latex") they exude when cut or damaged. Like the closely related genus Russula, their flesh has a distinctive brittle consistency.
The Agaricales are an order of fungi in the division Basidiomycota.As originally conceived, the order contained all the agarics (gilled mushrooms), but subsequent research has shown that not all agarics are closely related and some belong in other orders, such as the Russulales and Boletales.
The shape, colour, density and other properties (for instance, the gills here leak latex) are important when identifying mushroom species. "False" gills of Craterellus tubaeformis. In mycology, a lamella (pl.: lamellae), or gill, is a papery hymenophore rib under the cap of some mushroom species, most often agarics.
