Inonotus andersonii, also known as oak canker-rot and heart rot, is a species of resupinate polypore fungus that forms fruiting bodies underneath tree bark. [1] I. andersonii induces canker rot in oak, hickory, cottonwood, and willow trees. [2] [3] Wood that has been infected by this species appears bleached of color and crumbles easily. Where ...
The Index of Plant Diseases in the United States lists 133 fungi and 10 other causes of diseases on Carya species. Most of the fungi are saprophytes, but a few are damaging to foliage, produce cankers, or cause trunk or root rots. The most common disease of pignut hickory from Pennsylvania southward is a trunk rot caused by Poria spiculosa ...
Hypoxylon canker of shade trees is a secondary disease: a primary factor, such as drought or physical damage, usually causes the dying and decaying of the tree first before the Hypoxylon canker pathogen infects. [5] This will cause the tree to be in stress and potentially start to decay.
Shellbark hickory is free of serious diseases, but it is a host species for a variety of fungi. More than 130 fungi have been identified from species of Carya. These include leaf disease, stem canker, wood rot, and root rot-causing fungi. Specific information for shellbark hickory is not available. [4]
Removing blighted trees to control the disease was first attempted when the blight was discovered, but this proved to be an ineffective solution. Scientists then set out to introduce a hyperparasitic hypovirus into the chestnut blight fungus. The trees infected with virus-treated fungus responded immediately and began to heal over their cankers.
Mockernut hickory is extremely sensitive to fire because of the low insulating capacity of the hard, flinty bark. It is not subject to severe loss from disease. The main fungus of hickory is Poria spiculosa, a trunk rot. This fungus kills the bark, which produces a canker, causes heart rot and decay, and can seriously degrade the tree.
Biscogniauxia atropunctata, the hypoxylon canker, is a species [2] of sac fungus in the family Graphostromataceae. Like many other fungi in the genus, it is a plant pathogen ; specifically this species can cause Biscogniauxia (Hypoxylon) canker and dieback disease in host trees.
Ophiognomonia clavigignenti-juglandacearum is a mitosporic fungus that causes the butternut canker, a lethal disease of butternut trees (Juglans cinerea). It is also known to parasitize other members of the genus Juglans on occasion, and very rarely other related trees including hickories .
