Stachybotrys chartarum (/ s t æ k iː ˈ b ɒ t r ɪ s tʃ ɑː r ˈ t ɛər ə m /, stak-ee-BO-tris char-TARE-əm), [2] also known as black mold [3] is a species of microfungus that produces its conidia in slime heads. Because of misinformation, S. chartarum has been inappropriately referred to as toxic mold.
A wound to the bark, caused by pruning, insects, poor branch angles or natural cracks and splits, causes sap to ooze from the wound. Bacteria may infect this sap causing it to darken and stain the bark, eventually taking on a foamy appearance and unpleasant odor. This slimy ooze becomes toxic to the bark and eats into the tree.
The most infamous species, Stachybotrys chartarum (previously known as Stachybotrys atra) and Stachybotrys chlorohalonata, are known as black mold or toxic black mold in the U.S., and are frequently associated with poor indoor air quality that arises after fungal growth on water-damaged building materials.

The bracket fungus Fistulina hepatica is one of many that cause heart rot.. Heart rot is caused by fungi entering the trunk of the tree through wounds in the bark.These wounds are areas of the tree where bare wood is exposed and usually, a result of improper pruning, fire damage, dead branches, insects, or even animal damage.
Trees that display a thin, weak crown may persist for several years but may also die without displaying any symptoms. [2] Noticeable symptoms on the bole are the cracking of the bark, the formation of cankers, and beech snap, in which the trunk snaps above head height, under stress from wind as a result of the fungi weakening the wood.
Girdling prevents the tree from sending nutrients from its foliage to its roots, resulting in the death of the tree over time, and it can also prevent flow of nutrients in the other direction depending on how much of the xylem is removed. A branch completely girdled will fail; and, when the main trunk of a tree is girdled, the entire tree will ...
Many homes contain mold, according to the Centers for Disease Control. But the most reported side effect is typically hay fever-like allergies. But the most reported side effect is typically hay ...
Frost crack or Southwest canker [1] is a form of tree bark damage sometimes found on thin barked trees, visible as vertical fractures on the southerly facing surfaces of tree trunks. Frost crack is distinct from sun scald and sun crack and physically differs from normal rough-bark characteristics as seen in mature oaks , pines , poplars and ...
