Photo by Karen Dillman. Tuckermannopsis ciliaris. Rhizoplaca chrysoleuca (umbilicate). Placidium squamulosum. This partnership helps them to thrive in the worst climatic conditions. Next to it, the grey Herero lichen (Santessonia hereroensis) looks like a small leafless shrub, surrounded by Lecanora panis-erucae, a rim lichen species with the appearance of white gravel. It grows about 2cm per year. The photobiontic layer (Living only in light) is present in the upper part of the medulla which helps to provide enough light to the alga in the photosynthesis process. This results in too many marginal structures of foliose lichens. Photo by Karen Dillman. The whole picture covers an area about three inches across (8 cm). Foliose Lichen – Photo by: Snežana Trifunović. Psora nipponica (squamulose). Researchers are investigating the growth rate in lengthwise, breadthwise and area-wise spaces but yet a fruitful result has not received. Photo by Karen Dillman. Photo by Rick Demmer. Physcia caesia. Photo by Larry St. Clair. Punctelia subrudecta. In total, 327 species are included, while 19 taxa are excluded from earlier accounts of the flora. Photo by Hugh Nourse. Photo by Karen Dillman. Sticta beauvoissii. Xanthoria parietina. It is not always with the radical leafy lobes type, it can also be found with a Crenate (scalloped or notched margin) or rounded teethed margin. It grows mostly on oak and maple trees throughout the state. Flavocetraria cucullata (detail). Photo by Ralph Pope. Psora cerebriformis (squamulose). Hypogymnia physodes. Photo by Larry St. Clair. Every individual lichen is composed of a mycobiont, or fungus, combined with a photobiont or phycobiont in the form of green algae or cyanobacteria. Photo by Don Flenniken. Speerschneidera euploca (minutely foliose). The thallus of Pulmonaria (also known as lungwort) turns bright green when it is wet. ... Several species … The algae or bacteria photosynthesize, providing nutrients for the fungus, and giving the lichen its characteristic greenish or blueish color. Mailstop Code: 1103 Platismatia glauca. Foliose lichens are a horizontally growing leafy type of lichens that are always attached to the surface where it is growing. The Foliose lichen’s growth is relatively slow. There is a great diversity found in the forms and shapes of foliose lichen compared to Fruticose and Crustose. In many lichen species with foliose morphology, they are accompanied by changes in structural features, such as e.g. Usually the leafy lobes are found in different size and shapes. Smaller individuals occur on branches. Photo by Larry St. Clair. Photo by Larry St. Clair. It is also effective in certain drugs and believed to have properties to substitute penicillin in medicines. As different species of lichens have different colors, a wide variety of colored clothing was produced with the help of the lichens. Rhizoplaca melanophthalma (umbilicate).
