Some parasites attack many hosts and almost any and an inner spore-bearing mass, the gleba. The gleba is usually tissue or organ (Botrytis cinerea), others are restricted to one family differentiated into a number of chambers which are lined directly (Cystopus candidus) or genus (Phytophthora infestans) or by the hymenium (basidial layer), or else the chambers contain an specics (Pucciniastrum Padi), and it is customary to speak of root. interwoven mass of hyphae, the branches of which bear the basidia. parasites, leaf-parasites, &c., in expression of the fact that a given By the breaking down of the inner tissues the spores often come parasite occurs only on such organs—c.g.
