Verpa conica, commonly known as the bell morel or the early morel, is a species of fungus in the family Morchellaceae. Sometimes mistaken for a true morel, this species is characterized by a cap resembling a thimble that is freely attached to the stipe.

Verpa is a genus of ascomycete fungi related to the morels. Resembling the latter genus in edibility and form, the common name early morels is popular. There are five species in the widespread genus.

Suillus variegatus, commonly called the velvet bolete or variegated bolete, is a species of edible mushroom in the genus Suillus. Like all bolete-like species it has tubes, and pores, instead of gills under its cap. The mushroom forms a mycorrhizal relationship with pine and occurs in North America and Eurasia.

Fomitopsis pinicola, is a stem-decay fungus. Its conk (fruit body) is known as the red-belted conk or red-belted bracket. The species is common throughout temperate Eurasia. It is a decay fungus that serves as a small-scale disturbance agent in coastal rainforest ecosystems. It influences stand structure and succession in temperate rainforests. It performs essential nutrient cycling functions in forests. It is also a key producer of brown rot residues that are stable soil components in coniferous forest ecosystems.

Auricularia nigricans is a species of fungus in the family Auriculariaceae. Basidiocarps (fruitbodies} are gelatinous, ear-like, and grow on dead wood of broadleaf trees. It is found in southern and eastern Asia, North America, South America and the Caribbean. The name Auricularia polytricha, when used by authors from the Americas, is a synonym of A. nigricans. When used by Asian authors, it likely refers instead to Auricularia cornea.

Phellodon melaleucus, commonly known as the grey tooth, is a species of tooth fungus in the family Bankeraceae. It was originally described by Elias Magnus Fries in 1815 as a species of Hydnum. In 1881, Petter Karsten included it as one of the original three species in his newly circumscribed genus Phellodon. The fungus is widely distributed in Europe and North America, where it associates mycorrhizally with a wide range of host trees. It is considered vulnerable in Switzerland.

Thamnolia vermicularis, the whiteworm lichen, is the traditional name applied to a widespread, morphologically uniform group of fruticose lichens in the family Icmadophilaceae. The species forms loose mats or scattered tufts of slender, worm-like, chalky-white branches that typically reach up to 5 cm long, growing on tundra terrain across arctic and alpine habitats. It was first described in 1781 by the Swedish botanist Olof Swartz from the alpine regions of Lapland, and the modern scientific name was formalized by Ludwig Schaerer in 1850. Material traditionally identified as T. vermicularis

Gloiodon strigosus is a species of fungus belonging to the family Bondarzewiaceae. It was originally described by Olof Swartz in 1810, and received its current name by Petter Adolf Karsten in 1879. Like all species of the genus Gloiodon, it is a wood-inhabiting fungus producing annual fruiting bodies with a hydnoid hymenium on dead wood. It has been reported from the boreal-hemiboreal zones in Europe, North America and Asia. In Europe it is mainly found in Fennoscandia but are considered rare.

Teloschistes flavicans, also known as the golden hair-lichen, is a lichenized species of fungus in the genus Teloschistes (meaning "split-ends"; a reference to its finely divided thallus and dense coils which appear almost like brillopads), family Teloschistaceae. Recognized by its saffron-coloured pigmentation, this widespread fruticose lichen grows on rocks and branches of trees.

Enchylium tenax is a species of lichen known by the common names jelly lichen, black lichen, and desert lichen. It occurs in Arctic and temperate regions in the Northern Hemisphere. It is very common in North America, and it is present in Europe, Asia, and Africa. This lichen has a thick black or dark green gelatinous thallus which is variable in size. It is generally 1 to 3 centimeters wide. It contains a symbiont, the cyanobacterium Nostoc commune. It reproduces when pieces of the thallus break off, or when isidia, soredia, and apothecia are produced. It is tolerant of desiccation,

Rigidoporus microporus is a plant pathogen, known to cause white root rot disease on various tropical crops, such as cacao, cassava, tea, with economical importance on the para rubber tree (Hevea brasiliensis).

Ochrolechia frigida is a species of lichen belonging to the family Ochrolechiaceae. It was first formally described by Olof Peter Swartz in 1781, as Lichen frigidus. Bernt Arne Lynge transferred it to Ochrolechia in 1928.

Hexagonia hydnoides, also known as the hairy hexagonia, is a widely distributed species of bracket fungus in the Polyporaceae family. It is known to grow in tropical regions across the globe and to grow on dead wood tissues, particularly that of hardwoods. It is a plant pathogen and is largely saprophytic, decaying dead wood tissues.

Fomes fasciatus, common name the Southern Clam Shell, is a pathogenic white rot fungus in the family Polyporaceae. It is found in the southeastern United States and Central and South America where it can be seen growing on various dead and living hardwood trees. It was first described by Swedish botanist Olof Swartz in Jamaica in 1788 as Boletus fasciatus. It was later transferred by Cooke to Fomes fasciatus in 1885. The genus name "Fomes" translates to tinder as its holotype was historically used to start fires and the specific epithet "fasciatus" translates to "banded", in reference to the
