Peltigera malaceaMat felt lichenPeltigera lichens, commonly called dog lichens or felt lichens, vary in their photobionts between cyanobacteria and green algae, sometimes having both! P. malacea is a cyanolichen, meaning it contains a cyanobacterial photobiont colony! You can tell because of the dark, blue-tinted color of the thallus. This large foliose lichen grows in round patches up to 20cm in diameter made up of thick, curled lobes. The upper surface is deep bluish-green when hydrated, and bluish-brown or gray when dry, while the underside is white towards the lob margins, darkening toward the center. It has rounded, red apothecia at lobe ends, often curling or gaining crenulation with age. P. malacea grows among moss on moist soil at high elevations in temperate boreal forests. It has been recorded in North America, Europe, and Asia. images: source | sourceinfo: source | source | source | source -- source link
