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 reaction were named schaefferal A and B to honor Schäffer. [3]
A 2008 molecular phylogenetic study clarified the relationships among the mushroom-forming species of the family. [15] The authors demonstrated the existence of four distinct lineages of gilled mushrooms, which led to the description of Multifurca as a new genus separated from Russula [15] and the segregation of Lactifluus from Lactarius. [16] [17]
Russula is a very large genus composed of around 750 worldwide species of ectomycorrhizal mushrooms. They are typically common, fairly large, and brightly colored – making them one of the most recognizable genera among mycologists and mushroom collectors.
An umbo is a raised area in the center of a mushroom cap. Caps that possess this feature are called umbonate . Umbos that are sharply pointed are called acute , while those that are more rounded are broadly umbonate .
Fungal DNA barcoding is the process of identifying species of the biological kingdom Fungi through the amplification and sequencing of specific DNA sequences and their comparison with sequences deposited in a DNA barcode database such as the ISHAM reference database, [1] or the Barcode of Life Data System (BOLD).
This mushroom can range from lilac to purple-pink. Some North American specimens are duller and tend toward tan, but usually have purplish tones on the stem and gills. Younger specimens are lighter with more convex caps, while mature specimens have a darker color and flatter cap, ranging from 4–15 cm ( 1 + 5 ⁄ 8 – 5 + 7 ⁄ 8 in) in ...

[2] The mushroom can have a faintly bitter taste if eaten raw, but a pleasant nutty flavour when cooked ...
