⭐ Core Definition: Lactarius (fungus)

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. It is a large genus with over 500 known species, mainly distributed in the Northern hemisphere. Recently, the genus Lactifluus has been separated from Lactarius based on molecular phylogenetic evidence.

👉 Lactarius (fungus) in the context of Lactarius subdulcis

Lactarius subdulcis, commonly known as the mild milkcap or beech milk cap, is an edible mushroom in the genus Lactarius. It is brown in colour, with a large number of gills and a particularly thin layer of flesh in the cap.

Mycorrhizal, the mushroom is found from late summer to late autumn at the base of beech trees in small groups or individually, where it is one of the two most common species of fungi. Alternatively, it can be found in large groups in fields, sometimes with more than a hundred individual mushrooms. It is found in Europe, and, despite previous research to the contrary, is absent in North America.

Lactarius (fungus) in the context of Lamella (mycology)

In mycology, a lamella (pl.: lamellae), or gill, is a papery hymenophore rib under the cap of some mushroom species, most often agarics. The gills are used by the mushrooms as a means of spore dispersal, and are important for species identification. The attachment of the gills to the stem is classified based on the shape of the gills when viewed from the side, while color, crowding and the shape of individual gills can also be important features. Additionally, gills can have distinctive microscopic or macroscopic features. For instance, Lactarius species typically seep latex from their gills.

It was originally believed that all gilled fungi were Agaricales, but as fungi were studied in more detail, some gilled species were demonstrated not to be. It is now clear that this is a case of convergent evolution (i.e. gill-like structures evolved separately) rather than being an anatomic feature that evolved only once. The apparent reason that various basidiomycetes have evolved gills is that it is the most effective means of increasing the ratio of surface area to mass, which increases the potential for spore production and dispersal.
