Ascophore entirely sessile, expanded from the first, fleshy, under surface furnished with numerous tufts of hyphae; asci cylindrical, 8-spored, spores elongated, continuous, hyaline. Readily recognised by the dark-brown, crust-like ascophore, furnished on the under surface with numerous rhizoids or tufts of hyphae, by which it is fixed to the substratum. Rhizina inflata (Quel.) is a fairly common British fungus, met with on burnt soil, peat, etc., and often occurs abundantly on old heaps of sawdust. The ascophore is somewhat convex, more or less circular, margin often lobed, smooth, dark .,. ..M^i^'' Fig. 74.—1.^/"':'«« Injlata, ;2, sections of fungus showing rhizoids. nat. size; 3, ascus containing eight spores, also three paraphyses. highly mag. : 4, two free spores showing the thickened ends, highly mag. 3-10 cm. across; asci cylindrical, spores fusiform, 32-36 X 9-10 \i\ paraphyses numerous, tips brown. Professor Hartig has shown that this fungus is parasitic on the roots of young trees, more especially conifers, as Abies peciinata, Tsiiga mertcnsiana, Fseudofsuga doughisii, Picea sikkacnsis, Finns strobus, and Larix europaea. It also attacks the roots of Castanea vesca. On removing a plant that has.
