Name: Lasallia (papulosa, pensylvanica) - Dimelaena oreina - (Melanelia culbersonii) Nonvascular Vegetation Reference: NatureServe Biotics 2019 Description: This association is widely but locally distributed from the western Piedmont foothills in Maryland and Virginia through the Blue Ridge and Ridge and Valley portions of the Central Appalachians, north at least to the Delaware Water Gap in Pennsylvania and New Jersey. It occurs primarily on fully exposed, minimally weathered quartzite and sandstone boulderfields at elevations from about 300 to 1000 m (1000-3300 feet). On the largest occurrences, vascular plants are generally absent and lichens dominate these habitats. <i>Lasallia papulosa</i> and <i>Lasallia pensylvanica</i>, either singly or in combination, are generally abundant and conspicuous. <i>Dimelaena oreina</i> abundantly covers many dry, exposed rock surfaces that are not covered with <i>Lasallia</i> spp. and larger foliose lichens. Although of scattered occurrence, <i>Melanelia culbersonii</i> has been found across the full elevation range of the type and is a good diagnostic species, as it appears to be restricted mostly to siliciclastic rocks (and occasionally coarse-grained, quartz-rich granites that are nearly devoid of dark minerals) in this region. A variety of other foliose, crustose and fruticose lichen species are associated. Smaller, more marginal occurrences have sparse vascular plant cover, primarily stunted trees of <i>Betula lenta, Sassafras albidum</i>, and <i>Quercus montana</i>, ericaceous shrubs, and scrambling vines of <i>Parthenocissus quinquefolia</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:32986-{C285CE89-46D6-4295-9016-5363A83E26B8} Plot-observations of this Community Concept: 3
