This network of hyphse, which is characteristic of most fungi, is known as the mycelium. Often the mycelium is septated into segments, each of which is a small coenocyte. In one group, the Myxomycetes, the plant body is a plasmodium {fig. 818), consisting of an aggregation of cells which possess no cell-walls, but are capable of amceboid movements. The Plasmo- dium is of course a form of ccenocyte. Fig. 818..

The most important and most general phenomenon of intetcalary growth in the surface of the hymenium consists in the introduction of new asci already mentioned, which goes on for a long time at all points. This is the cause of the long continued superficial growth of many hymenia. Some smaller disk-shaped apothecia, those for example of Ascobohis and Fyro- nema, show no marginal progressive growth
