squamulose การใช้

• But A . socialis has areolas that become lobed and squamulose.
• It has a lower surface when squamulose, but without a lower cortex.
• Some people who study lichens ( lichenologists ) group squamulose lichens separately from crustose lichens.
• When the edges of the areolas lift up from the substrate, it is called squamulose.
• Crustose and squamulose lichens have an upper cortex, but do not have a lower cortex.
• But these leafy parts lack a lower cortex, which distinguishes crustose and squamulose lichens from foliose lichens.
• In squamulose lichens the part of the lichen thallus that is not attached to the substrate may also appear leafy.
• It differs from Pleopsidium flavum in having a smooth, smaller squamulose thallus and larger apothecia ( spore producing structures)
• Fruticose, foliose, crustose, and squamulose lichens generally have up to three different types of tissue, some lichens.
• More common in the Sierras is the similar species " Acarospora thamnina ", which is truly squamulose with overlapping scales.
• The thallus of the lichen may be foliose ( leafy ), subfruticose ( somewhat shrubby ) or granular-squamulose ( scaly ).
• Crustose and squamulose lichens lack a lower cortex, and the medulla is in direct contact with the substrate ( biology ) that the lichen grows on.
• The " Cladonia " morpho-type has many more species, and is generally described as a group of squamulose ( grow from squamules ), cup-bearing lichens.
• Crustose and squamulose lichens have only an upper cortex, with the " inside " of the lichen in direct contact with the surface they grow on ( the "'substrate "').
• ""'Placidium acarosporoides " "'( "'Mojave stipllescale "') is a glossy reddish to dark brown or black squamulose lichen dotted with black perithecia that grows on rock.
• ""'Peltula " "'is a genus of small dark brown to olive or dark gray squamulose lichens that can be saxicolous ( grow on rock ) ) or terricolous ( grow on soil ).
• ""'Acarospora socialis " "'( "'bright cobblestone lichen "') is a usually bright yellow aereolate to squamulose crustose lichen in the Acarosporaceae family that grows up to 10 cm wide, mostly on rock in western North America.
