Amanita bisporigera is a deadly poisonous species of fungus in the family Amanitaceae. It is commonly known as the eastern destroying angel amanita, the eastern North American destroying angel or just as the destroying angel, although the fungus shares this latter name with three other lethal white Amanita species, A. ocreata, A. verna and A. virosa. First described as a new species in 1906, A. bisporigera is classified in the section Phalloideae of its genus together with other amatoxin-containing species. The mushroom has a smooth white cap that can reach up to 10 centimetres (4 inches)

Amanita brunnescens, also known as the brown American star-footed amanita or cleft-footed amanita is a native North American mushroom of the large genus Amanita. It differs from A. phalloides (the death cap) by its fragile volva and tendency to bruise brown.

Amanita flavoconia, commonly known as yellow patches, yellow wart, orange amanita, yellow-dust amanita or the American yellow dust amanita, is a species of mushroom in the family Amanitaceae. It has an orangish-yellow cap with yellowish-orange patches or warts, a yellowish-orange annulus, and a white to orange stem. Common and widespread throughout eastern North America, it grows on the ground in broad-leaved and mixed forests, especially in mycorrhizal association with hemlock.

Amanita calyptroderma also known as coccora, coccoli or the Pacific amanita, is a white-spored mushroom that fruits naturally in the Sierra Nevada and coastal forests of the western United States during the fall, winter and spring.

Sebacina is a genus of fungi in the family Sebacinaceae. Its species are mycorrhizal, forming a range of associations with trees and other plants. Basidiocarps (fruit bodies) are produced on soil and litter, sometimes partly encrusting stems of living plants. The fruit bodies are cartilaginous to rubbery-gelatinous and variously effused (corticioid) to coral-shaped (clavarioid). The genus has a cosmopolitan distribution.

Amanita velatipes or veiled-bulb amanita is a species of Amanita from eastern North America.

Amanita elliptosperma, commonly known as the Atkinson's destroying angel, is a basidiomycete fungus, one of many in the genus Amanita. Although its toxicity is not confirmed, it is assumed to be deadly poisonous like its close relatives. Originally described from North Carolina, it is found in the eastern United States from New England to eastern Texas.

Amanita chrysoblema, with the common name American fly agaric, yellow/orange variant, is a basidiomycete fungus of the genus Amanita. Although named chrysoblema, it is traditionally thought to be an Amanita muscaria variant, a group of fungi commonly known as fly agarics. A. chrysoblema has a cap that ranges from red to yellow to white. The cap may have grooves on its margins, and the cap often has an irregular pattern of universal veil remnants in the form of warts. Furthermore, the base is bulbous and is encased by a volva. Multiple studded ridges are found as the base transitions to the

Eocronartium muscicola is a species of fungus belonging to the order Platygloeales. It is currently the only species in the monotypic genus Eocronartium. In the UK its recommended English name is moss rust. The species forms clavarioid basidiocarps (fruit bodies) on mosses, on which it is parasitic. At least 21 moss species, all in the subclass Bryidae, are recorded as hosts for Eocronartium muscicola. The fungus parasitizes its host through its gametophytic transfer cells. The species appears to be widespread, with most reports from Europe, North and South America.
