Bot. xiv, p. 245. v] LABOULBENIALES 171 Labi The group Laboulbeniales includes some six hundred species arrangedin over fifty genera. All are minute external parasites on insects, chiefly onmembers of the Coleoptera. They appear to do but little injury to the host,inducing at must a slight irritation but never causing death, indeed their ownexistence depends on that of the insect to which they are attached since,unlike many other fungi, their life ends with that of their host. The Laboulbeniales are all of fairly simple structure (fig. 130) and showan underlying similarity of type. In all cases the vegetative part consists ofa receptacle, usually two-celled, attached to the integument of the host bya blackened base or foot. From t
