. Lichens. Lichens. 382 ECOLOGY Parmelia prolixa is the most abundant of the Parmelias: it covers large spaces of the rocks and frequently competes for room with the Ramalinas, or in other areas with Physcia aquila and Lecanora parella. A number of crustaceous species which form the sub-vegetation of the Ramalina belt, and also on the same level, clothe the steeper rock faces where shelter and moisture are insufficient to support the foliose forms. "In general the sub-vegetation of the eastern and northern coasts is largely composed of species that are common in Alpine and upland regions. Stock Photo

. Lichens. Lichens. I30 MORPHOLOGY ZukaU claims to have found breathing-pores in Cornicularia {Parmelid) tristis and in several other Parmeliae, notably in Parmelia stygia. The thallus of the latter species has minute holes or openings in the upper cortex, but they are without any definite form and may be only fortuitous. ZukaP published drawings of channels of looser tissue between the exterior and the pith in Oropogon Loxensis and in Usnea bar- bata. He considered them to be of definite service in aeration. The fronds of Ramalina dilacerata by stretching develop a series of elongate holes. R Stock Photo
