Cyathus striatus, commonly known as the fluted bird's nest, is a common saprobic bird's nest fungus. This fungus resembles a miniature bird's nest with numerous tiny "eggs"; the eggs, or peridioles, are actually lens-shaped bodies that contain spores. The color and size of this species can vary somewhat, but they are typically less than a centimeter wide and tall, and grey or brown in color. The common name splash cups alludes to the method of spore dispersal: the sides of the cup are angled such that falling drops of water can dislodge the peridioles and eject them from the cup. C. striatus

Peltigera is a genus of approximately 100 species of foliose lichens in the family Peltigeraceae. Commonly known as the dog or pelt lichens, species of Peltigera are often terricolous (growing on soil), but can also occur on moss, trees, rocks, and many other substrates in many parts of the world. Most species of Peltigera have the cyanobacterium Nostoc as the dominant photobiont but some have the algae Coccomyxa. The presence of both a green alga and a cyanobacterium makes some tripartite; in this case they show cephalodium growths containing the third partner, Nostoc. Because of their

Peltigera aphthosa is a species of lichen known by the common names green dog lichen, leafy lichen, felt lichen, and common freckle pelt. It has a circumpolar distribution, occurring throughout the Arctic, boreal, and temperate regions of the Northern Hemisphere. This lichen has a large thallus that may exceed one meter in width. It is divided into lobes up to about 10 centimeters long and 6 wide. It is green, becoming pale as it dries. The thallus is dotted with cephalodia, which contains one of the two symbionts, a species of Nostoc. The other is a species of Coccomyxa. These perform

Cladonia foliacea is a species of lichen belonging to the family Cladoniaceae. It has a cosmopolitan distribution.

Naematelia encephala (synonym Tremella encephala) is a species of fungus producing pink, brain-like, gelatinous basidiocarps (fruit bodies). It is widespread in north temperate regions and is parasitic on another species of fungus (Stereum sanguinolentum) that grows on dead attached and recently fallen branches of conifers. In the UK, its recommended English name is conifer brain.

Cladonia coccifera or madame's cup lichen is a species of fruticose, cup lichen in the family Cladoniaceae. It was first described by Swedish lichenologist Carl Linnaeus in his 1753 work Species Plantarum. German botanist Carl Ludwig Willdenow transferred it to the genus Cladonia in 1787. The lichen has apothecia and bright red pycnidia atop of yellowish to grey-green podetia that are 1–2 cm (0.4–0.8 in) high. The base of the thallus comprises rounded squamules (scales) with a yellow to orange-brown undersurface. It typically occurs on acidic peaty and sandy soils. The lichen has a

Peltigera canina, commonly known as the dog lichen, is a widely distributed species of foliose lichen in the family Peltigeraceae. It was originally described by Carl Linnaeus in his 1753 work Species Plantarum. German botanist Carl Ludwig Willdenow transferred it to the genus Peltigera in 1787. This species is currently undergoing research as it is likely multiple species under one united name.

Cladonia gracilis or the smooth cup lichen is a species of fruticose, cup lichen in the family Cladoniaceae. It was first described as a new species by Carl Linnaeus in his 1753 work Species Plantarum. German botanist Carl Ludwig Willdenow transferred it to the genus Cladonia in 1787. In North America, it is known colloquially as the "smooth Cladonia". The Cladonia gracilis group is a monophyletic group of species that all are morphologically similar to C. gracilis. In this group, the delimitations of species is difficult due to the morphological similarity between taxa, and the fact that

Cladonia botrytes or the wooden soldiers cup lichen is a species of cup lichen in the family Cladoniaceae. Its habitat includes secondary xylem.

Stereum hirsutum, commonly known as the false turkey tail, hairy stereum, or hairy curtain crust, is a species of fungus and a plant pathogen that infects coniferous and deciduous trees.

Bjerkandera adusta, commonly known as the smoky polypore or smoky bracket, is a species of fungus in the family Phanerochaetaceae. It is a plant pathogen that causes white rot in live trees, but most commonly appears on dead wood.

Onygena equina, commonly known as the horn stalkball, is a species of fungus in the family Onygenaceae. The fungus grows on putrefying hooves and horns, and can digest the keratin in those substrates. Fruit bodies are small and white, with thick stipes supporting a "head" shaped like a flattened sphere. The skin, or peridium, of the head appears powdery or like a white crust, and breaks open in maturity, falling off in irregular pieces to expose the pale reddish-brown powdery spores within. The fungus is known from Europe and North America.
