Book Description
From the Introduction.The Fungi are parasitic or saprophytic Thallophyta entirely destitute of chlorophyll, and possessing in the very large majority of cases a vegetative portion, the mycelium, made up of filaments or hyphae. The group is a very ancient one, the earliest known undoubted fungi occurring among the remains of Rhynia and Homia in the Old Red Sandstone of the Muir of Rhynie, Aberdeenshire. This material consists of aseptate hyphae and vesicles which doubtless served the purpose of reproduction (frontispiece).Fungal hyphae may be non-septate and coenocytic, or they may undergo transverse septation, in which case their constituent cells are either uninucleate or multinucleate. Any division other than transverse is extremely rare; it occurs, for example, in the development of certain multicellular (muriform) spores (fig. 1), and in the initiation of the perithecium in Strickeria and of the pyenidium in Pleospora and Phoma.As a rule the hyphae are richly branched; they elongate by apical growth and usually spread loosely through the substratum; in certain cases, especially in relation to the fructifications of the higher forms, they become woven into a dense mass which gives in section the appearance of a tissue, and is therefore described as pseudoparenchymatous; when fructifications are embedded in such a mass it is termed a stroma; a similar weft of hyphae sometimes give rise to root-like strands of which the best example is the so-called rhizomorph of Armillaria mellea, or to a compact resting body or sclerotium the outer cells of which are modified to form a thick-walled rind, protecting the vegetative mycelium against desiccation.Frequent anastomoses take place between hyphae, either by means of short branches forming loops, bridges or H-pieces, or by means of so-called clamp-connections which join adjacent cells; such arrangements facilitate the passage of food and may, in certain cases, become sufficiently numerous to form a net-work.The mycelium begins its development as a germ-tube put out from one of the numerous types of fungal spore. Where the spore wall is very thin the wall of the germ-tube may be continuous with it (zoospores), but in the majority of cases the wall of the germ-tube is continuous only with the inner layer of the spore wall. In such cases one or more germ-tubes may break through the wall of the spore at spots not previously recognizable, or they may find an exit through special pits or germ-pores formed during the development of the spore. The germ-tube elongates and receives the contents of the spore...
