Gelatinous Lichens, which when moistened look like dark, olive-green, or almostblack lumps of wrinkled and wavy jelly or as if composed of variously-dividedbands and strips packed together into little cushions. In the gelatinous expansions last mentioned the algal cells are arranged inmoniliform rows and are interwoven with the hyphal filaments of the fungusthroughout the entire thickness of the thallus, as in Collema pulposum (seefig. 57 ^ and 57^), or else they form regular ribbon-shaped double rows, interwovenwith few hyphse, as in Ujjhebe Kerneri (see fig. 57 ^). In crustaceous, foliaceous,and fruticose lichens, the algal cells constitute a disorderly heap and are crowdedtogether in the middle stratum of the thallus, where they are imbedded betweenan upper and a lower layer of dens
