Entoleuca mammata is a species of fungus in the genus Entoleuca . It is responsible for the plant disease hypoxylon canker in hardwood trees such as quaking aspen ( Populus tremuloides ) [1] and other aspens and poplars, [2] Salix myrsinifolia [1] and other willow species, [1] [2] rowan ( Sorbus aucuparia ), [1] Sitka alder ( Alnus viridis ), [2] birch (Betula spp.), [2] apple ( Malus spp.), [2] oak (Quercus spp.), [2] and hop-hornbeam ( Ostrya spp.).

Populus is a genus of 25–30 species of deciduous flowering plants in the family Salicaceae, native to most of the Northern Hemisphere. English names variously applied to different species include poplar, aspen, and cottonwood.
A catkin or ament is a slim, cylindrical flower cluster, with inconspicuous or no petals, usually wind-pollinated (anemophilous) but sometimes insect-pollinated. They contain many, usually unisexual flowers, arranged closely along a central stem that is often drooping. They are found in many plant families, including Betulaceae, Fagaceae, Moraceae, and Salicaceae.
The engrailed and small engrailed are moths of the family Geometridae found from the British Isles through central and eastern Europe to the Russian Far East and Kazakhstan. The western Mediterranean and Asia Minor and the Caucasus represent the southern limit of the distribution. In the north, the distribution area ends at the Arctic Circle. It also occurs in North America. Debate exists as to whether they make up one species, or whether E. crepuscularia actually refers only to the small engrailed, with the engrailed proper being separable as E. bistortata.
The grey dagger is a moth of the family Noctuidae.
Brenneria is a genus of Pectobacteriaceae, containing mostly pathogens of woody plants. This genus is named after the microbiologist Don J. Brenner.
Silver leaf is a fungal disease of trees caused by the fungal plant pathogen Chondrostereum purpureum. 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. It is spread by airborne spores landing on freshly exposed sapwood. For this reason cherries and plums are pruned in summer, when spores are least likely to be present and when disease is visible. Silver Leaf can also happen on poming fruits like apples and pears. Plums are especially vulnerable.
Populus grandidentata, commonly called large-tooth aspen, big-tooth aspen, American aspen, Canadian poplar, or white poplar, is a deciduous tree native to eastern North America.
The biogeoclimatic zones of British Columbia are units of a classification system used by the British Columbia Ministry of Forests for the Canadian province's fourteen different broad, climatic ecosystems. The classification system, termed Biogeoclimatic Ecosystem Classification, exists independently of other ecoregion systems, one created by the World Wildlife Fund and the other in use by Environment Canada, which is based on one created by the Commission for Environmental Cooperation (CEC) and also in use by the US Environmental Protection Agency (EPA). The system of biogeoclimatic ecosystem classification was partly created for the purpose of managing forestry resources, but is also in use by the British Columbia Ministry of Environment and Climate Change Strategy and other provincial agencies. A biogeoclimatic zone is defined as "a geographic area having similar patterns of energy flow, vegetation and soils as a result of a broadly homogenous macroclimate."
Coleophora anatipennella is a moth of the case-bearer family (Coleophoridae).
Rheumaptera undulata, the scallop shell, is a moth of the family Geometridae. It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. It is found in most of the Palearctic realm and North America.
Hypoxylon canker of shade trees is a weak ascomycete fungus that negatively affects growth and can eventually lead to the death of already dying or diseased host trees. There are many different species that affect different trees. For example, Hypoxylon atropunctatum, a common species, is found on oak trees, Hypoxylon tinctor affects sycamore trees, and Hypoxylon mammatum infests aspen trees.

Hypoxylon mammatum is found only on hardwoods, most commonly on poplar and willow. In B.C., it has been reported on aspen, willow, and Sitka alder. Elsewhere in North America it has also been found on other poplar spp., birch, apple, oak, and hop-hornbeam.
