Abstract
DR. MINKS is already well known as the author of several treatises on the biology and morphology of Lichens, in each of which the ideas set forth are quite original, and at the same time directly opposed to modern views regarding the structure presented by this group of plants. The present contribution must be considered as part iii. of “Contributions to a knowledge of the structure and life of Lichens,”of which the previous parts appeared in an Austrian scientific publication (K. K sool.-bot. Gesell. zu Wien). The present, preceded by a digest of the leading ideas embodied (Oester. Bot. Zeitschr., 1896, p. 50) appears as an independent publication. The previo'us parts contain, amongst other new views, the ptatement that many species considered as valid by slichenologists, are the outcome of parasitism between two or more originally distinct species, the product being a pseudo-species, differing in structure and general appearance from the species concerned in its production. In the book under consideration, the contents of which could not be understood without a knowledge of the author's previous views and theories, we are introduced to a second method which, as before, results in the wholesale production of what may be termed pseudo-species, due to the intermingling and gradual changing of the layers of the thallus. This change is said to be due to “Protrophie”; a statement which must be accepted in good faith. The definition given would be next to meaningless in English, hence it is offered in the original language.
