Vhron. 16 INTRODUCTION TO THE STUDY OF FUNGI We have biietly directed attention to the ordinary develop-ments of mycelium, whether filamentous or sclerotioid, butthere are still one or two special modifications which mustobtain a passing reference. Of these the mycelium of theUredineae is deserving of mention, being formed within thetissues of living plants, and often starting centrifugally from adefinite point of infection. The hyphae resemble ordinarymycelial filaments, but, like all internal mycelia, are delicate,branching and anastomosing so as to form compact cushions orspore beds, or, in other cases, much diffused and scattered. Inannuals or upon deciduous parts the mycelium is, of course, onlyannual, but if it passes into perennial parts, as it may readilydo in shrubs and other perennials, the mycelium becomesperennial. Take, for instance, the Juniper, in which theCrymnosporangium may bintroductiontost00cook
