Dibotryon morbosum or Apiosporina morbosa is a plant pathogen, which is the causal agent of black knot. [1] [2] It affects members of the Prunus genus such as; cherry, plum, apricot, and chokecherry trees in North America. The disease produces rough, black growths that encircle and kill the infested parts, and provide habitat for insects.
The chaga fungus will continue to cause decay within the living tree for 10–80+ years. While the tree is alive, only sterile mycelial masses are produced (the black exterior conk). The sexual stage begins after the tree, or some portion of the tree, is killed by the infection. I.
Exidia nigricans is a species of fungus in the family Auriculariaceae.In the UK, it has the recommended English name of warlock's butter. [1] It produces black, gelatinous basidiocarps (fruit bodies) and is a common, wood-rotting species throughout the Northern Hemisphere, typically growing on dead attached branches of broadleaf trees.
Exidia glandulosa is a species of fungus in the family Auriculariaceae. In the UK, it has the recommended English name of witch's butter. [1] In North America it has variously been called black witches' butter, black jelly roll, [2] or warty jelly fungus.

The inedible fungus Daldinia concentrica is known by several common names, including King Alfred's cake, cramp balls, and coal fungus. It is a common, widespread saprotrophic sac fungus, living on dead and decaying wood. The fruit of this fungus is hemi-spherical, with a hard, friable, shiny black fruiting body 2 to 7 centimeters wide.
Tar spot does not usually have an adverse effect on the trees' long-term health. [1] R. acerinum is an Ascomycete fungus that locally infects the leaves of trees and is a biotrophic parasite. [2] The disease is cosmetic and is therefore usually controlled only with sanitation methods. [3]
The fungus is introduced into the tree during this wounding where it subsequently germinates and grows. The fungal mycelium initially colonize tissue immediately surrounding the beetle galleries. However, in less than a month black, oval-shaped, inky cankers extend considerably beyond the galleries and may reach more than 3 cm in length in ...
This bracket fungus, commonly known as the giant polypore or black-staining polypore, is often found in large clumps at the base of trees, although fruiting bodies are sometimes found some distance away from the trunk, parasitizing the roots. M. giganteus has a circumboreal distribution in the northern Hemisphere, and is widely distributed in ...
