The most infected needles are prematurely shed by December. Because the infected needles are within the interior of the tree, the newer needles on the outer surface of the pines are flushed green and resistant to the disease. However, the premature shedding of needles in the interior can extend outwards leading to a loss in overall growth.
This fungal disease affects the needles of conifers, but is mainly found on pine. Over 60 species have been reported to be prone to infection and Corsican Pine (Pinus nigra ssp. laricio) is the most susceptible species in Great Britain. [3] It was first recorded in Britain on Corsican pine in 1954 in a nursery in Dorset.

Pine-pine gall rust, also known as western gall rust, is a fungal disease of pine trees. It is caused by Endocronartium harknessii (asexual name is Peridermium harknessii ), an autoecious , endocyclic , rust fungus that grows in the vascular cambium of the host. [ 1 ]
The nematodes drop off the beetle, and infect healthy pine trees when the adult beetles eat the young pine branches. [16] The pine wilt nematode is spread by a number of bark beetles and wood borers, typically associated with the genus Monochamus of pine sawyers. [17] Pine sawyers lay their eggs in the bark of dead timber.
To get this par-tea started, go for white pine, easily identifiable by its clusters of five needles. Cut the needles into smaller pieces , add them to boiling water, remove from heat, let steep ...
P. schweinitzii is a polypore, although unlike bracket fungi the fruiting body may appear terrestrial [citation needed] when growing from the roots or base of the host tree. [2] The fruiting bodies, appearing in late summer or fall, commonly incorporate blades of grass, twigs, or fallen pine needles as they grow. [3]
