Mr. G. Massee has intimated ^ that theThelephoreac constitute the base, and also the starting-point, inthe evolution of the Hymenomycetes, and, further, that fromthe Thclqiilioreae all the other orders have directly originated. In this family, as in the others, the species are variable inform as well as in texture. Only in Craterellus is the substancefleshy, attenuated in some species to membranaceous, often witha central stem and a funnel-shaped pileus, the outer or under sur-face being clothed with a ribbed or rugose hymenium (Fig. 56).Cladoderris and Beccariella are tough and leathery, mostly fan-shaped, sometimes funnel-shaped, but with a warted TheUpliora the substance is tough, but softer and more p. 112.

The form is variable,from stipitate and funnel-shaped toclosely adnate and resupinate. It isnotable that in the majority of speciesthe spores are globose and rough, mostlyslightly coloured. We are disposedto place here the genus Lachnocladium,which some authors include in theClavarieae, on account of the erect,branched habit, resembling some speciesof Clavaria, forgetting that there arealso erect, branching species of TJiele-phora, to which these species of Lachno-cladium are closely allied in texture rather than to fleshyClavariae. Stereum in form approaches Thelepliora, but thesubstance is firmer, more leathery, and the pileus has a distinctouter stratum analogous to that inPolystiduSy with an
