From this comparison I arrived at the conclusion that both plants, as to their outer habit and anatomical structure, seem to agree perfectly. The plant has an f/føa-like, flat thallus, perforated by numerous roundish holes, smaller in the young thallus, larger in the older, this receiving thereby a reticular appearance. The holes seem to originate through the tissue in certain places becoming absorbed. At any rate I have several times in younger parts of the thallus found small, roundish, rather well-marked spots in which the tissue was much thinner than in the other part of the thallus, these thinner parts being undoubtedly the beginning of the holes. A transverse section of the thallus (cp. Fig. 353 a) shows that this consists on both sides of a rather loose and thin-walled cell- tissue and of a cavity in the middle through which filaments are running in all directions. S.
