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 ...
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.
Polypores are also called bracket fungi or shelf fungi, and they characteristically produce woody, shelf- or bracket-shaped or occasionally circular fruiting bodies that are called conks. [1] Over one thousand polypore species have been described to science, [ 2 ] but a large part of the diversity is still unknown even in relatively well ...
In systematic virus infections leaf spots caused by viruses show a loss of green colour in leaves, due to chlorosis which is a repression of chlorophyll development. [1] Leaves may yellow and have a mottled green or yellow appearance, show mosaic (e.g. chlorotic spotting) and ringspots (chlorotic or necrotic rings). [7]
P. schweinitzii is a polypore, although unlike bracket fungi the fruiting body may appear terrestrial [citation needed] when growing from the roots or base of the host tree. [1] The fruiting bodies, appearing in late summer or fall, commonly incorporate blades of grass, twigs, or fallen pine needles as they grow. [2]
Laricifomes officinalis, also known as agarikon, eburiko, or the quinine conk, is a wood-decay fungus that causes brown heart rot on conifers native to Eurasia, North America, and Morocco. This fungus is the only member of the genus Laricifomes. The fruiting bodies grow in large conks on the trunks of trees.
