Description Parmelia species have a foliose (leafy) thallus with a substrate attachment ranging from loose to tight. The lobes comprising the thallus are rounded, more or less straight, and may be contiguous or overlapping (imbricate). The texture of the upper thallus ranges from smooth to foveolate (covered with puts and depressions). crottle Parmelia, largest genus of foliose (leafy) lichens, which includes among its members the species commonly known as crottle and skull lichen. Crottle, the largest foliose lichen, resembles crumpled leather and sometimes grows 90 to 120 centimetres in diameter. It is characterized by a black underside.
Parmelia sp.
Parmelia that belongs to the Parmeliaceae Family is a foliose lichen combined with one or two groups of fungi in Phylum Ascomycota or Basidiomycota and algae, which might be green algae or blue-green algae (cyanobacteria). It is generally called "Stone Flower," "Charila," "Pattharphool," or "Shilaaapushpa" in India. The Parmeliaceae is a large and diverse family of Lecanoromycetes. With over 2700 species [2] in 71 genera, it is the largest family of lichen -forming fungi. The most speciose genera in the family are the well-known groups: Xanthoparmelia ( 822 species ), Usnea (355 species), Parmotrema ( 255 species ), and Hypotrachyna (262 species). [3] Well-developed ascocarps on a shield lichen (Parmelia sp.). Credit: J. Stevenson, UF/IFAS. Parmelia, or shield lichen, is a common genus with a foliose growth habit (Figure 8). These large and easily observed species can be found in a variety of habitats. Their abundance has led to their being used to monitor lichen growth rates as well as. Parmelia is one of the most representative genera within Parmeliaceae family. • Parmelia lichens arise as valuable tools for biomonitoring environmental. • Parmelia lichens produce particular specialized metabolites. • Parmelia spp. have promising pharmacological activities. Abstract
Foliose Lichen Parmelia Sp On Rock Important Pioneer In Primary Rock
Biology of Parmelia sp. Lichens. Parmelia saxatilis grows wood and rock substrates. Parmelia sulcata is more commonly found on trees. There are at least seven species of Parmelia genus in Alaska (U.S.F.S. Dillman, 2010). Microclimates can produce portions of an individual organism that grow at different rates, and have different chemistry than. View. Parmelia is a genus of medium to large foliose lichens.:78. The ends of the leaf-like lobes are often squarish-tipped.:78. The upper surface is pale bluish-gray to light brown in direct sunlight, with a network web-like ridges and depressions.:78. The lower surface is black and has rhizines anchoring it to the substrate.:78 (. The worldwide, ecologically relevant lichen-forming genus Parmelia currently includes 41 accepted species, of which the Parmelia sulcata group (PSULgp) and the Parmelia saxatilis group (PSAXgp) have received considerable attention over recent decades; however, phycobiont diversity is poorly known in Parmelia s. lat. Parmelia sp. 1 - Upper surface greenish (but turning yellowish in herbarium), often convex; pseudocyphellae generally confined to area of lobe tips; isidia tending at first to arise along lobe margins (though later also developing over upper surface) Reactions: Cortex K+ yellow, medulla K+ yellow becoming red, PD+ orange to red.

Lobaria scrobiculata: USA: Arnold et al. Nephroma arcticum Peltigera aphthosa Peltigera leucophlebia Peltigera malacea Peltigera neopolydactyla To evaluate the importance of morphological and chemical characters used in the recognition of species within the Parmelia omphalodes group, we performed phylogenetic, morphological and chemical analyses of 335 specimens, of which 34 were used for molecular analyses.
The thallus is usually divided into lobes (Parmelia sp.) with various degrees of branching, but in some species (Umbilicaria sp.) the thallus is from one single unbranched lobe or a "multilobe" with limited branching . Parmelia that belongs to the Parmeliaceae Family is a foliose lichen combined with one or two groups of fungi in Phylum Ascomycota or Basidiomycota and algae, which might be green algae or blue-green algae (cyanobacteria). It is generally called "Stone Flower," "Charila," "Pattharphool," or "Shilaaapushpa" in India.

2. Antimicrobial Compounds Extracted from Endolichenic Fungi. The need for new antimicrobial drugs is enhanced by the emergence of microbial resistance against almost all the currently available antibiotics and the sudden appearance of deadly viral infections [].Discovery of novel antimicrobial drugs was speculated as a solution to the growing threat of antibiotic-resistant microorganisms by. Parmelia sulcata is a widely distributed species and one of the most common taxa in temperate Europe. The first intra-specific molecular studies on P. sulcata showed an unexpectedly high genetic.
