Agaricus arvensis (Horse Mushroom) Schaeff. 1774
edible fungi species in the agaricaceae family
Agaricus arvensis, commonly known as the horse mushroom, is a mushroom-forming fungus of the genus Agaricus.
Boletus reticulatus (Summer Bolete) Schaeff. 1774
edible fungi species in the boletaceae family
Boletus reticulatus (alternately known as Boletus aestivalis (Paulet) Fr.), and commonly referred to as the summer cep is a basidiomycete fungus of the genus Boletus. It occurs in deciduous forests of Europe, where it forms a symbiotic mycorrhizal relationship with species of oak (Quercus). The fungus produces fruiting bodies in the summer months which are edible and popularly collected. The summer cep was formally described by Jacob Christian Schäffer as Boletus reticulatus in 1774, which took precedence over B. aestivalis as described by Jean-Jacques Paulet in 1793.

Lactarius torminosus (Woolly Milk-cap) (Schaeff.) Pers. 1797
edible fungi species in the russulaceae family
Lactarius torminosus, commonly known as the woolly milkcap or the bearded milkcap, is a large species of agaric fungus. It was first described scientifically by Jacob Christian Schäffer in 1774 as an Agaricus, and later transferred to the genus Lactarius in 1821 by Samuel Frederick Gray. L. torminosus officially became the type species of Lactarius in 2011 after molecular studies prompted the taxonomic reshuffling of species between several Russulaceae genera. The caps are convex with a central depression, and attain a diameter of up to 10 cm (4 in). A blend of pink and ochre hues, the cap
Russula emetica (The Sickener) (Schaeff.) Pers. 1796
edible fungi species in the russulaceae family
Russula emetica, commonly known as the sickener, emetic russula, vomiting russula, is a basidiomycete mushroom, and the type species of the genus Russula. It was first described in 1774. It has a red, convex to flat cap up to 8.5 cm (3.3 in) in diameter, with a cuticle that can be peeled off almost to the centre. The gills are white to pale cream, and closely spaced. A smooth white stem measures up to 10.5 cm (4.1 in) long and 2.4 cm (0.9 in) thick. There are many similar russulas with a red cap and white stem and gills, some of which can be reliably distinguished only by microscopy. The
Russula virescens (Greencracked Brittlegill) (Schaeff.) Fr. 1836
edible fungi species in the russulaceae family
Russula virescens is a basidiomycete mushroom of the genus Russula, and is commonly known as the green-cracking russula, the quilted green russula, or the green brittlegill. The species was described as new to science in 1774 by Jacob Christian Schaeffer. It can be recognized by its distinctive pale green cap that measures up to 15 cm (6 in) in diameter, the surface of which is covered with darker green angular patches. It has crowded white gills, and a firm, white stipe that is up to 8 cm (3 in) tall and 4 cm (1.6 in) thick. It resembles species such as Russula parvovirescens and R.
