Leptogium platinum [Endangered/ Red-listed] Not exactly like a bat wing with all those crowded fruiting bodies, this curious lichen does have the same transverse wrinkles that help distinguish it from Peacock vinyl.
Ramalina subleptocarpha [Blue-listed] This lichen is in the Ramalinaceae family. This unique ribbon-like lichen is branched from a narrow holdfast in two’s (dichotomously) and the branches can be up to 15 cm long. It is pale grey to greenish yellow, very flat and thin and never forming bundles of hyphae. It grows only on the bark of trees. It occurs south to California.
Collema auriforme [Red-listed] Curious with its habit of growing on our Garry oaks, this species more commonly occurs on alkaline ground or rock in other jurisdictions. With its prominently thickened margin (like an ear) and profusion of globular propagules, it’s easy to recognize and locally rare. Known on Salt Spring Island only from one location.
Usnea intermedia [Red-listed] Usnea intermedia (western bushy beard) is a grayish-yellowish pale green, irregularly much-branching, stiff shrubby foliose lichen commonly anchored on holdfasts on trees, often on oaks. Abundant apothecia are convex discs with a ring or thallus-like margin having tendril-like fringe radiating from it. It was formerly called U. arizonica in North America.
Pseudocyphellaria crocata [Blue-listed] Without a doubt, this eye-catching lichen is our showiest species and always a delight to find. In our area, it grows mostly on Garry oaks but also occasionally over rock. Known on Salt Spring Island from one location.
Lempholemma polyanthes [Blue-listed] This lichen has a small to spreading thallus, often over 2 cm in size, crustose, thin and membrane-like, sometimes ± lobate; upper surface: blackish or dark olive green, smooth or rough and appearing coarsely granulose...
Dermatocarpon leptophyllodes [Blue-listed] A foliose or leaf lichen in the Parmeliaceae family that is found only on coastal rocks. It is a pale greenish colour with tiny leaf-like lobes that are no more than 0.4mm wide. It has a lower surface that can be somewhat shiny and can look leathery with a dusting of black spots. It occurs in Western North America, Northern Europe, Asia and Southern Africa.
