Part 79

A parallel example is that phenomenon seen in certain polypores which only attack twigs or branches and not stumps or trunks, whilst others grow exclusively on stumps. We know little of the reasons for these demarcations, even when they occur within the same host. Mycology, therefore, offers to the beginner and the professional many opportunities in physiology and ecology.

In grassland areas it is difficult to know where to draw the line between one plant-community and another when listing species, for although ecologically distinct both would come under the name grassland. In the field, however, this is often very obvious and there is little doubt that fungi can give just as accurate an indication as to the soil-type, as many mosses or vascular plants. In sand-dune systems, the mobile dunes offer a different ecological niche to that of the fixed dunes which in many ways resemble grasslands. Thus although the lists below are split into easily manageable units, some flexibility must still be allowed. It is meant only as a guide--and will differ in some cases from one place to another, even within the British Isles.
