Porodaedalea pini, commonly known as the pine conk, [1] is a species of fungus in the family Hymenochaetaceae. It is a plant pathogen that causes tree disease commonly known as "red ring rot" or "white speck". This disease, extremely common in the conifers of North America, decays tree trunks, rendering them useless for lumber. [2]
Its conk (fruit body) is known as the red-belted conk. The species is common throughout temperate Europe and Asia. [1] 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 ...
Cronartium quercuum, also known as pine-oak gall rust is a fungal disease of pine (Pinus spp.) and oak (Quercus spp.) trees. Similar to pine-pine gall rust , this disease is found on pine trees but its second host is an oak tree rather than another pine.
A drawing on the lower side of the sporocarp of G. applanatum. A peculiarity of this fungus lies in its use as a drawing medium for artists. [13] When the fresh white pore surface is rubbed or scratched with a sharp implement, dark brown tissue under the pores is revealed, resulting in visible lines and shading that become permanent once the fungus is dried.
Ganoderma oregonense (also known as the west-coast reishi, western varnished conk, lacquer fungus, and/or American ling-chi) is a species of bracket fungus that causes root and butt white rot in conifers in northwestern coastal North America.
These fruit bodies have a wide variety of morphologies, ranging from the typical mushroom shape, to brackets (conks), puffballs, cup fungi, stinkhorns, crusts and corals. Many species of fungi, including yeasts, moulds and the fungal component of lichens, do not form fruit bodies in this sense, but can form visible presences such as cankers.
The name chaga comes from the Russian name of the fungus, ча́га, čága, which in turn is borrowed from the word for "mushroom" in Komi, тшак, tšak, the language of the indigenous peoples in the Kama River Basin, west of the Ural Mountains. It is also known as the clinker polypore, cinder conk, black mass and birch canker polypore. [17]
Pine-pine gall rust is especially important in areas containing large stands of pine species due to ability of the causal fungus to infect other pines without first infecting an alternate host. Pine-pine gall rust is economically significant because of its detrimental effects on lumber content, quality, and growth rate.
