Species of the Week
Different lichen species specialize in growing on these three types of substrate, so this is an important first clue to a lichens identity. Those with a flattened and crusty appearance are called crustose lichen. Weaker algal cells thus violated die, and were it not for periodic reproduction, so too would the lichen. A foliose species, the common greenshield lichen can mainly be found growing on the bark of trees, and less often, on rock. WebGreen shield lichens are in the Parmeliaceae, the Shield Lichen Family. At school we were taught that lichens were an intimate partnership between a fungus and an alga, but it's not always that simple. In some areas it is occasionally replaced by the rarer Usnea florida. The lichen bodies are attached to the outer tree bark and remain on the surface. Lichenproduce unique biochemicals to fend off herbivores, prevent freezing, and stop seeds from germinating in their soft, moist tissue. There is a large
for the fungus. Future field tests and experiments are certain to clarify the origin story. Urban areas tend to be nearly devoid of
Lichen reproduction is also complicated, as it involves two different species that must reproduce independently and then come into close contact to form a union. 
The two main substrate characteristics associated with lichen growth are moisture retention and exposure to sunlight. 7. Close-up of foliose lichen. New Jersey Agricultural Experiment Station
It is attached to the substrate (usually bark) at occasional points by tufted or fibrous, anchoring structures (rhizines). In the case of conifer or evergreen trees , some lichens can survive in the resulting year-round partial shade. Spribille, T. et al Basidiomycete yeasts in the cortex of ascomycete macrolichens Science Volume 353 Issue 6298, 21 July 2016, pp 488-492. It also occurs in the west,

This widespread and common species is normally found growing on soil and rotting wood, can be seen all year round. Were Weirdo Ediacarans Really Lichens, Fungi, and Slime Molds? Scientific American 13 December 2012. Beneath Notice, our book of borescopic mycology. Meanwhile, reactions with rainwater can make the surface of the lichen more transparent, which vividly reveals underlying pigments. Consequently, lichen hyphae penetrate rock surfaces to depths of several millimeters seeking water, and, depending on the type of rock, minerals as well. This Parmeliaceae-related article is a stub. It is smooth at first, often becoming rough, wrinkled, and folded with age. it seems to be fond of white pines. Click on the header to sort A-Z, and again to sort Z-A. 
branches littering the ground around it. For lichens growing on exposed tree bark, the degree to which moisture is retained as it flows down the tree is the key factor. Deciduous trees have more lichens than conifers because their leafless trunks are sunlit for six months of the year whereas evergreens are ever shaded. The vegetative body of a lichen composed of both the alga and the fungus. The relationship between the fungus and the algae in a lichen is complex. A conspicuous medium to large leafy lichen, it is pale grey when dry and yellow green when wet. Its a very cool story, linked below. 2. Here are but a few examples that illustrate their importance: Take a photo tour on theMaryland Biodiversity Project website. The reproductive lives of lichen are unique, involving asexual methods, as well as sexual reproduction of the fungal symbiont. Fruticose lichenhave branched growths with finger or thread-like projections. Do trees weaken due to the amount of bark covered by lichens? The

The symbiosis gives very specific features lichens, including a high sensitivity to environmental pollutants which makes them excellent indicators of air quality and habitat. Lichen species on bark do not follow the classic succession of crustose followed by foliose and then fruticose that is evident in the colonization of rock. Ben Hoare is a wildlife writer and editor, and proud to be an all-round nature nerd. However, some lichens, notably reindeer moss (Cladinia rangiferina), are a major food source for animals and are quite likely propagated in their droppings. In the winter months when deciduous trees are devoid of greenery and mostly annual undergrowth has died back, only the grays and browns of rocks, dirt, leaf litter, and boles remain. In vegetative reproduction, any fragment or shred of lichen containing both the algal and fungal components that breaks off the original can form a new lichen body. The quality of precipitated rainwater is why lichens are useful for environmental monitoring as their growth correlates to air quality. While the trees leaves may shade the available sunlight for the lichens during the warm weather growing season, the lichens do not similarly affect the leaves. My favorite of the lichens I saw was Parmotrema sulcate,(Hammered Metal Lichen). Contents 1 Identification 2 Similar species 3 References 4 External links Identification Flavoparmelia caperata is a medium to large foliose lichen that has a very distinctive pale yellow green upper cortex when dry. While sunlight and water are the essential ingredients for photosynthesis, nitrogen, phosphorous and potassium are also required for plant growth (the three numbers on a fertilizer bag refer to these elements). 
In reality, the relationship frequently ranges from commensalism, where the fungus benefits but the algae do not, to outright parasitism, where the algae are harmed for the benefit of the fungus. This fabulous lichen sprouts dense clusters of tiny fingers up to 2cm high, which resemble old-fashioned red-tipped matches. The life forms are composed of a fungus (kingdom Fungi) and most often a green alga (kingdom Protoctista) and/or a cyanobacterium (kingdom Monera). Yet individual species may only exist within a restricted habitat or geographic range. Lichens can
No controls are necessary. Paradoxically, one of the best ways to see lichens
It rarely produces spore-producing structures (apothecia). Using lichen species diversity as a measure of air quality is common in Europe (especially the UK), because European lichenologists have developed lists of lichen indicator species i.e., lists of lichen species that are especially sensitive to air pollution vs. lists of lichen species that are especially tolerant. A new lichen association can be created only when fungal spores come in contact with the appropriate algae or cyanobacteria in the correct habitat. This week, then, we

If you are one of the Lichens of North America documents hundreds of species of lichens that reside on trees. Powdery, crusty colors on surfaces, reminiscent of spray paint. Rocks are not good at retaining moisture. Flavoparmelia, a new genus in the lichen family Parmeliaceae (Ascomycotina). on rocks. Groerig, David J., Jim A. Chatfield, Sarah D. Ellis, Dr. Landon H. Rhodes, and Dr. Michael J. Boehm, (2009) "Lichens." It is less well known that fungi need these same nutrients for the same metabolic reasons. Unlike plants, lichens do not have leaves, stems, or roots, or a waxy outer cuticle to control body water content. These lichen seed packets take various forms including soredia that are miniscule balls of fungal hyphae surrounding a few algal cells and schizidia, which are simply flakes of the upper layer of the fungal thallus which also contains the algal layer. Many lichens commonly found on living tree bark are seldom discovered growing on rock or soil, as these different lichens need varying surfaces to become established. http://www.fs.fed.us/wildflowers/beauty/lichens/whatare.shtml WebAll of the lichen species recorded in NC, their distribution in the state; their relative abundance in each region; their periods of occurrence in the state; Common Greenshield Lichen: Hypotrachyna horrescens: Hairy-spined Shield Lichen: Hypotrachyna livida: Wrinkled Loop Lichen: Hypotrachyna minarum: New Forest Loop Lichen: It can also sometimes grow
It was hard to capture the pounded metal look. The most conspicuous part of many lichens is the thallus, the manifestation of the fungal partner. The photosynthetic partner of the lichenized fungus is called the photobiont and can be either green, brown, golden algae or cyanobacteria, a type of bacteria that contains chlorophyll formerly called blue-green algae. However, lichens may co-exist on trees with other organisms that are causing disease or injury. It can be found from Nova Scotia to Manitoba, south
Kendrick, B. Lichen sexual reproduction is quite complicated as two or more organisms are contained in the lichen. Flavo as a prefix means yellow, distinguishing these lichens from the blue tint of other shield lichens yellow hues combine with blue so that the overall effect is green. They are extremely sensitive to sulfur dioxide and are not usually found in industrial areas. The photobiont, in this case Trebouxia, also reproduces using spores when it is independent of the fungus, but only reproduces asexually once lichenized. Parmotrema hypotropum, (Powdered Ruffle Lichen), and Flavoparmelia caperata, (Common Greenshield Lichen), are both commonly found here in Virginia.
