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]
Spore prints are usually white to cream, black, or shades of red, purple, or brown. The poisonous false parasol (Chlorophyllum molybdites) has a green spore deposit. [3] Although the spore print is generally used to help identify the genus of a specimen, on occasion it can be used to help distinguish between similar species.
A cystidium (pl.: cystidia) is a relatively large cell found on the sporocarp of a basidiomycete (for example, on the surface of a mushroom gill), often between clusters of basidia. Since cystidia have highly varied and distinct shapes that are often unique to a particular species or genus, they are a useful micromorphological characteristic in ...
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.
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).
Volvopluteus gloiocephalus, commonly known as the big sheath mushroom, rose-gilled grisette, or stubble rosegill, is a species of mushroom in the family Pluteaceae.For most of the 20th century it has been known under the names Volvariella gloiocephala or V. speciosa, but recent molecular studies have placed it as the type species of the genus Volvopluteus, newly created in 2011.
Termitomyces, the termite mushrooms, is a genus of basidiomycete fungi belonging to the family Lyophyllaceae. [3] All species in the genus are completely dependent on fungus-growing termites, the Macrotermitinae, to survive, and vice versa. [4] They are the food source for these termites, who enjoy an obligate symbiosis with the genus [5 ...
The spores of a Cortinarius mushroom are rust brown to brownish red in color. It is usually possible to identify a mushroom as being a member of the genus, but extremely difficult to positively identify the species as many of the species are nearly identical. All mushrooms in this genus form mycorrhizae. [3]
