Dibotryon morbosum is a fungus that affects the genus Prunus. Included in this genus are multiple species of trees and shrubs, such as: Dibotryon morbosum infects are Prunus serotina (wild cherry trees), Prunus persica (peach trees), Prunus domestica (plum trees), and Prunus cerasus (sour cherry trees).

A striking and easily recognised fungus, Plums and Custard takes its common name from its plum-red scaled cap and crowded custard yellow gills. The flesh is cream-coloured and spore print creamy white. The base colour of the cap under the purplish scales is yellow. [1]
Taphrina pruni is a fungal plant pathogen of blackthorn (Prunus spinosa) that causes the pocket or bladder plum gall, a chemically induced distortion of the fruit (sloes), producing swollen on one side, [1] otherwise deformed and flattened fruit gall without a stone. [2]
Chondrostereum purpureum is a fungal plant pathogen which causes Silver leaf disease of trees. It attacks most species of the rose family Rosaceae, particularly the genus Prunus. The disease is progressive and often fatal. The common name is taken from the progressive silvering of leaves on affected branches.
Taphrina padi is a fungal plant pathogen that induces the form of pocket plum gall that occurs on bird cherry (Prunus padus). The gall is a chemically induced distortion of the fruits, which are swollen, hollow, curved and greatly elongated, [ 1 ] without a seed or stone, but retaining the style . [ 2 ]
A fungus in the genus Taphrina often attacks the plums; the young ovaries swell, often much larger than full grown plums, become hollow and often persist on the tree in winter. Known as "plum pockets", they appear pale green, leathery to the touch, and hollow with the exception of a few fibrous bands. The disease reduces regeneration of the plums.
Inonotus obliquus, commonly called chaga (/ ˈ tʃ ɑː ɡ ə /; a Latinisation of the Russian word ча́га), is a fungus in the family Hymenochaetaceae. It is parasitic on birch and other trees. The sterile conk is irregularly formed and resembles burnt charcoal.
In California and Idaho, it has been found on plum and prune trees. In Europe, the disease can be found on apricots, peaches, and cherries. Leucostoma canker has also been witnessed in South America and Japan. [1] The spread of disease is favored in cool, wet, and humid conditions in late fall or early spring when conidia are most abundant.
