In 1963, Shu Chün Teng named it Pyropolyporus fomentarius.  The fungus is known to have been used as a firestarter in Hedeby, and it is known that the fungus was used as early as 3000 BCE. Phellinus tremulae spreads through airborne basidiospores.  The young fruit bodies are soaked in water before being cut into strips, and are then beaten and stretched, separating the fibres.  The pores are circular, and there are 2–3 per millimetre. SEARCH JJ COLLETT NATURAL AREA FOUNDATION. Populus trichocarpa, the black cottonwood, western balsam-poplar or California poplar, is a deciduous broadleaf tree species native to western North America. Their leaves tremble in the slightest breeze like the quaking aspen. What uses are there for aspen in the lumber trade? Amadou is produced from the flesh of the fungus fruit bodies.

Aspens have increased in popularity as a forestry cultivation species, mostly because of their fast growth rate and ability to regenerate from sprouts. By placing an ember in a hole in the conk, it would smolder through the day (or longer) allowing the quick building of cooking and warming fires in a new location. The bark also contains lenticels that serve as pores for gas exchange (similar to the stomata on leaves). The species often propagates through its roots to form large clonal groves originating from a shared root system.  There are management steps to preserve healthy stands of aspen. The high stem turnover rate combined with the clonal growth leads to proliferation in aspen colonies. Comment from contributor T:

, Pscheidt, J. W., and C. M. Ocamb. Lepidoptera (Butterflies and Moths) Report, http://www.mushroomexpert.com/phellinus_tremulae.html. , Another possible management strategy would be to use the fungus Phoma etheridgei as an inhibitory agent against Phellinus tremulae. Unfortunately, there are often no external indicators of decay, and it is difficult to predict decay volumes.
 The species is commonly known as the tinder fungus, hoof fungus, tinder polypore, ice man fungus or false tinder fungus. Much of my research time this past year has been devoted to documenting the fungi of a number of natural areas in south-central Alberta. Your continued respect for others is appreciated ensuring safety for all. Sep 17, 2020 - Explore Buggy's board "Painted Conks", followed by 443 people on Pinterest.
English names variously applied to different species include poplar, aspen, and cottonwood.  In all infected species, the most obvious sign of rot is a conk on the stem of the tree. To report wildlife sightings, hunting violations, vandalism, public safety concerns, or any other matter that may require a Conservation Officer, please call the Alberta Parks Enforcement Line 24/7 at 403-350-5066”. These names are considered obligate synonyms; that is, different names for the same species based on a single description or specimen. Most of the symptoms of this disease are internal, with the only external signs of a diseased aspen being fruiting bodies called conks.  In the Mediterranean, oak is the typical host. Conks are perennial and can survive for up to twenty years. Aspen is a common name for certain tree species; some, but not all, are classified by botanists in the section Populus, of the Populus genus. I'm a new sawyer in northern Wisconsin where we have a lot of aspen.  While typically shaped like a horse's hoof, it can also be more bracket-like with an umbonate attachment to the substrate. Pando, also known as the trembling giant, is a clonal colony of an individual male quaking aspen determined to be a single living organism by identical genetic markers and assumed to have one massive underground root system. Aspen trees diseased with aspen trunk rot decrease the economic value of the lumber. 22 Oct. 2014, "Aspen Bracket (Phellinus Tremulae (Bondartsev) Bondartsev & P.N.
The pathogen that causes this disease is the fungus Phellinus tremulae. Lichens – Photos Submitted by Charles Bird. This has been attributed to several different factors, such as climate change, which exacerbates drought and modifies precipitation patterns. This lowers the cost of reforestation after harvesting since no planting or sowing is required. From Gene Wengert, forum technical advisor: It is very regional.
A conk is the woody fruiting body of the fungus that forms a triangular shape. In contrast with many trees, aspen bark is base-rich, meaning aspens are important hosts for bryophytes  and act as food plants for the larvae of butterfly (Lepidoptera) species—see List of Lepidoptera that feed on poplars.
The high stem turnover regime supports a diverse herbaceous understory. Fomes fomentarius (commonly known as the tinder fungus, false tinder fungus, hoof fungus, tinder conk, tinder polypore or ice man fungus) is a species of fungal plant pathogen found in Europe, Asia, Africa and North America. The trees have tall trunks, up to 25 meters tall, with smooth pale bark, scarred with black. Many fungi have annual fruiting bodies and show up only in the warmer weather from late spring to fall. "Decay of Aspen and Balsam Poplar in Alberta.
Jones, Alan C., and Michael E. Ostry. It has a number of uses, notably for making matches and paper where its low flammability makes it safer to use than most other woods. The infection of aspen trunk rot is localized, but decay can spread 2–3 meters above and below the infection site. United States Department of Agriculture, 1983.
THANK YOU!! Phellinus tremulae can maintain a resting state for 20 years, so older trees have a greater chance of being infected. A single conk found on an aspen can indicate advanced decay of up 82% of the tree volume.  The decayed wood shows black lines in the lightly coloured decayed areas; these are known as pseudosclerotic layers or demarcation lines. They are large deciduous trees, 30–60 m tall, with leaves with a rounded base, pointed apex, and a whitish waxy coating on the underside of the leaf; this latter distinguishes them from most other poplars. Question 0000000994 00000 n , Aspen tree wood has many commercial uses due to its soft yet strong and heat-tolerant wood. Web. These traits can help plants and animals increase their survival rates during a fire and/or reproduce offspring after a fire. It is still used today in fly fishing for drying flies.  In 1818, Georg Friedrich Wilhelm Meyer described Polyporus fomentarius in his Primitiae Florae Essequeboensis, and this name was sanctioned by Elias Magnus Fries in the 1821 publication of the first volume of his Systema Mycologicum. It formerly also occurred in southern Wisconsin, but is extirpated there as a native tree. A friendly reminder to keep dogs on leashes so they don't surprise other canines, people or resident wildlife.  However, in addition to the obviously infected damaged trees, F. fomentarius is known to be an endophyte, meaning that healthy trees which are not sporting F. fomentarius fruit bodies could still be infected. Betula papyrifera is a short-lived species of birch native to northern North America. The balsam poplars are light-demanding trees that require considerable moisture. The resulting material is referred to as "red amadou".  Phellinus tremulae has spherical spores with four basidiospores per basidium and generative, skeletal hyphae.  In regions where aspen grow quickly and mature early, decay also advances rapidly and early in the tree's life. Some aspen colonies become very large with time, spreading about 1 m (3.3 ft) per year, eventually covering many hectares. Fagus grandifolia, the American beech or North American beech, is the species of beech tree native to the eastern United States and extreme southeast Canada. Populus tremuloides is a deciduous tree native to cooler areas of North America, one of several species referred to by the common name aspen. The plant is located in the Fremont River Ranger District of the Fishlake National Forest at the western edge of the Colorado Plateau in south-central Utah, United States, around 1 mile (1.6 km) southwest of Fish Lake. A similar species, Phellinus tremulae, infects quaking aspen. Larix laricina, commonly known as the tamarack, hackmatack, eastern larch, black larch, red larch, or American larch, is a species of larch native to Canada, from eastern Yukon and Inuvik, Northwest Territories east to Newfoundland, and also south into the upper northeastern United States from Minnesota to Cranesville Swamp, West Virginia; there is also an isolated population in central Alaska.  Infected trees become very brittle, and cracks can occur in the affected tree due to wind.
Spores enter new hosts through branch stubs or wounds.

, It is predicted that climate change will impact the prevalence of aspen trunk rot through changing moisture conditions.
