Russula subsect. Griseinae is a subsection of the genus Russula , which is within the section Heterophyllae . The type species is the Russula grisea , the pigeon pigeon . The subsection was introduced by Julius Schäffer in 1933. Following Henri Romagnesi , the taxon hasthe rank of a section in some mycologists. Within the Heterophyllae , the Griseinae form the largest and undoubtedly also the most difficult group of forms, the species of which can often only be distinguished microscopically.
features
The subsection contains large or medium-sized blisters with fragile, cream to ocher-colored lamellas. The hat is gray, green, purple or olive colored and more or less solid. The smell is insignificant, the taste is mostly mild, but sometimes sharp in the lamellae or in young specimens. The guaiac reaction is only weak. The iron sulfate reaction varies from species to species; it can be nearly negative to vividly positive. Usually the flesh turns pink or more or less bright pink-orange, but in some cases there is a slightly yellowish to almost dirty greenish discoloration.
The hyphae end cells of the cap skin are variable, but always more or less subdivided into shorter cells, which are sometimes almost as long as they are wide and never taper to a point. The cap skin contains a relatively large number of pileocystides , which can be easily stained with sulfovanillin. The “hairs” are septated to different degrees. The type species is Russula grisea , the pigeon pigeon .
Systematics
The taxon Griseinae is found in both Romagnesi and Sarnari . With Romagnesi it has the rank of a section, with Sarnari it is a subsection. In contrast to Bon , both authors put the grass-green deaf ( R. aeruginea ) in a separate subsection Illicinae . Singer interprets the subsection like receipt. But with him it is called Subcompactinae and is within its Regidae section, which corresponds to the Heterophyllae section . The slightly different mycorrhizal anatomy and the lack of purple coloring, which are typical for the other representatives of the section, speak in favor of separating the grass-green pigeon from the other species of the subsection.
The investigated species of the subsection Griseinae form a very uniform group with regard to the morphology and anatomy of their fruiting bodies as well as their mycorrhizae. Since there is still too little molecular biological data available, it can only be stated that the few species examined are all within the section Heterophyllae . The results of the R-DNA analysis of the grass-green pigeon are interpreted differently; while one working group classified the species within the section Heterophyllae, another working group (Miller & Buyck) considers it to be a sister taxon, which stands next to the women's Täubling and the Ingratae section .
