.
Amanita caesarea, commonly known in English as Caesar's Mushroom, is a highly regarded edible mushroom in the genus Amanita, This mushroom has an orange-red cap, initially hemispherical before convex and finally flat. The surface is smooth, and margins striated, and it can reach 15 - 20 cm in diameter. The free gills are pale to golden yellow, as is the cylinder-shaped stipe, which is 8-15 cm tall and 2-3 cm wide. The ring hangs loosely and is lined above and smooth below. The base of the stipe is thicker than the top and is seated in a greyish-white cup-like volva, which is a remnant of universal veil. The spores are white.
This mushroom fruits in oak woodland sometimes mixed with conifers, from early summer to mid autumn. It is found in North Africa and southern Europe, particularly in the hills of northern Italy.

Cortinarius collinitus is a species of fungi in the family Cortinairiaceae.The cap is 3–9 cm in diameter, convex to flat in shape, with a sticky, gelatinous surface (in moist conditions). The gills are adnexed, close, and pallid or pale violet in color. The stipe is typically 6–12 cm long and 1–1.5 cm thick, solid, equal, and has transverse scaly-looking bands. The spore print, like most Cortiniarius species, is rusty-brown. Edibility is unknown for this species.

Amanita bisporigera, is one of deadly white mushroom (destroying angle) in the genus Amanita and found in eastern and western North America. The toxin has contained is amatoxin . It is deadly toxin and characterized by having a white stalk and gills. The cap can be pure white, or white at the edge and yellowish, pinkish, or tan at the center. It has a partial veil, or ring (annulus) circling the upper stalk, and the gills are "free," not attached to the stalk. The cap is usually about 5–12 cm across; the stem is usually 7½–20 cm long and about ½–2 cm thick. They are found singly or in small groups.This species form ectomycorrhizal relationships with the roots of certain trees. They grow in or near the edges of woodlands. Also be found on lawns or grassy meadows near trees or shrubs.

Amanita rubescens, found in Europe and eastern North America, known as the European blusher, growing on poor soils as well as in deciduous or coniferous woodlands.The European blusher has a reddish-brown convex pileus (cap), that is up to 15 cm across, and strewn with small cream-coloured warts. The flesh of the mushroom is white, becoming pink when bruised or exposed to air. The stipe (stem) is white with flushes of the cap colour, and grows to a height of up to 15 cm. The gills are white and free of the stem, and display red spots when damaged. The ring is striate (i.e. has ridges) on its upper side. The spores are white, ovate, amyloid.
These species is edible when cooked. European Amanita rubescens is known to contain a hemolytic poison in its raw state. The flavour of the uncooked flesh is mild, but has a faint acrid aftertaste. The smell is not strong.

Russula virescens is a basidiomycete mushroom of the genus Russula, and is sometimes called the green-cracking Russula, the quilted green Russula, or the green brittlegill. A popular edible fungus with a mild or nutty taste and its distribution encompasses Britain, Europe, and Asia, where it occurs solitary or scattered on the ground in both deciduous and mixed forests, forming mycorrhizhal associations with hardwood trees like oak and European beech.
It can be recognized by its distinctive characteristic: cap is at first dome or barrel-shaped, becoming convex and flattened with age with a diameter of up to 15 cm .The cuticle of cap is thin, green coloured and can be readily peeled off the surface to a distance of about halfway towards the cap centre. The gills are white to cream coloured, crowded together, and have an adnate attachment to the stem. The gills are interconnected at their bases by veins. The stem is cylindrical, white and of variable height, up to 8 cm tall and 4 cm wide; it is roughly the same thickness at both the top and the base.

Amanita inaurata, is one species of the genus Amanita, and have similar characteristic with Amanita ceciliae, cap is convex with size 5 – 12 cm, gills is free from the stem or slightly attached to it, stem is long 7-18 cm in length, up to 2 cm thick; tapering slightly to apex; whitish; finely hairy or fairly smooth; without a ring; without a swollen base; with a whitish to greyish volva, flesh is white and spore print is white, inamyloid.
It is found mycorrhizal with hardwoods and conifers; growing alone, scattered, or gregariously; distribution in the Pacific Northwest, the Southwest, and Texas .
