6-434: List of Lactifluus species Lactifluus is one of three genera of mushroom -forming fungi containing species commonly named " milk-caps ", the others being Lactarius and Multifurca . It has been separated from Lactarius based on molecular phylogenetic evidence but is very similar to that genus. There are roughly 150 known Lactifluus species, which have a mainly tropical distribution but are also found in
12-435: The north temperate zone and Australasia . Some of them are edible mushrooms . Lactarius Multifurca Russula Lactifluus The genus Lactifluus was described in 1806 by French naturalist Henri François Anne de Roussel , with the type species Lactifluus piperatus . Later, Lactifluus was largely considered a synonym of Lactarius , until molecular phylogenetic work showed in 2008 that Lactarius
18-739: The pileipellis and stipitipellis ( cuticle of the stipe) and sphaerocytes in the trama of the lamellae are common in Lactifluus , but rare in Lactarius species. Several species in the genus are edible . Lactifluus volemus especially is a choice mushroom in the northern temperate region. List of Lactifluus species Lactifluus is a genus of milk cap fungi in the family Russulaceae. Its species were formerly classified in Lactarius but have been split off as separate genus based on molecular phylogenetic evidence. A 2017 revision divided
24-421: The brittle flesh of the fruit bodies and the milk-like latex exuded when bruised. So far, synapomorphic characters for the genus have not been discovered, there are only tendencies that distinguish it from Lactarius . Pleurotoid (laterally stiped) fruitbodies are only known in Lactifluus , while species with closed (angiocarpous) fruitbodies only occur in Lactarius . Microscopically, thick-walled elements in
30-532: The genus in four subgenera : Lactifluus , Lactariopsis , Gymnocarpi and Pseudogymnocarpi . They are further subdivided into section , but not all species are assigned to named sections. Many of these new groups do not correspond to previous subdivisions based mainly on morphology. As of 2021, there are roughly 150 described species, classified in four subgenera. Some notable species are listed below under their respective subgenera. Lactifluus closely resembles its lookalike genus Lactarius , with whom it shares
36-525: Was not a monophyletic group. In the following, the name Lactarius was conserved for the biggest of the sub clades revealed, containing most well-known north temperate species. Thus, the name Lactifluus could be used for the smaller genus, necessitating only a few name changes, as combinations with Lactifluus had already been made previously for many temperate species. New combinations have since been proposed for several species formerly classified in Lactarius . A phylogenetics-based revision in 2017 divided
