Jack pine, also known as grey pine or scrub pine, is a North American pine.
A plant canker is a small area of dead tissue, which grows slowly, often over years. Some cankers are of only minor consequence, but others are ultimately lethal and therefore can have major economic implications for agriculture and horticulture. Their causes include a wide range of organisms as fungi, bacteria, mycoplasmas and viruses. The majority of canker-causing organisms are bound to a unique host species or genus, but a few will attack other plants. Weather and animal damage can also cause stress to the plant resulting in cankers. Other causes of cankers is pruning when the bark is wet or using un-sterilized tools.
Scleroderris canker, or Brunchorstia disease, Gremmeniella abietina, is a species of fungal diseases infecting coniferous forests. The main symptom is the death of the needles, leading to the death of the tree. In the forest industry, fighting off an infection of Scleroderris canker is usually not cost-effective. Clearing is often preferred over fungicidal methods, as the latter is harmful to other living organisms.

The Lahmiales are an order of fungi in the Ascomycota, or sac fungi. The order has not been assigned to any class. The taxon is monotypic and contains a single family, the Lahmiaceae, which in turn contains the single genus Lahmia.
Farnoldia is a genus of lichenized fungi within the Lecideaceae family.
Koerberiella is a genus of lichenized fungi within the Lecideaceae family.
Boothiella is a genus of fungi within the Chaetomiaceae family. This is a monotypic genus, containing the single species Boothiella tetraspora.
Polytolypa is a monotypic genus of fungus containing the single species Polytolypa hystricis. First classified in the Onygenaceae family, as of 2008 it is considered to be in the Ajellomycetaceae, although there is still uncertainty as to its phylogenetic relationships with other similar genera. This species is only known from a single specimen derived in the laboratory from a specimen of dung of the North American porcupine, Erethizon dorsatum, collected in Ontario, Canada. Polytolypa hystricis contains bioactive compounds that have antifungal activity.
Philipp Wilhelm Albrecht Zimmermann was a German botanist. He was a Professor of Botany at several different Universities . He was a botanist and collector of fungi and spermatophytes, who worked in Indonesia and Tanzania from 1902 to 1919. He moved to Indonesia in 1896 and studied applied botany. In 1902 he moved to Africa to join the Amani Research Institute that was established that year. He returned to Germany after World War I in 1920. He wrote about the cultivation of coffee among other things related to botany, but most of his writings were destroyed during World War II.
