ON THE STRUCTUEAIi ANATOMY OF FUNGI. 31 



flesh, may be. The Hymenium covers the interior of the cup, and 

 is usually of brighter tint than the outside surface. The Spores 

 are not free. Descriptive terms as already explained can be 

 applied to these mushrooms. 



CLAVARIEI. These are mostly nothing but Stems. They 

 consist of solid fleshy masses of branches and branchlets, or are 

 Simple, that is without branches, merely little fingers or clubs. 

 Most are terrestrial, some are small, mere little filaments ; others 

 are of considerable bulk. A few grow solitary, others in clumps. 

 Tints vary. The Hymenium covers the surface. A few fresh 

 terms, not hitherto explained, will be used in describing these 

 species, and are also applicable to certain Hydnums and Poly- 

 pores. 



Bundled, many stems bunched together. 



Dichotomous, the branchlets in equal pairs. 



Divaricate, straggling, spread about irregularly. 



Fusiform, spindled, twisted, with tapered ends. 



Laciniate, split into a sort of fringe. 



Ligulate, the ends flattened like a strap. 



Obovate, ovate but inverted. 



Petaloid, like the petals of a flower. 



PUFF-BALLS AND TUBERS. These are globose bodies; 

 the former grow above ground, the latter are subterranean. 

 The colours are various shades of white, yellow, brown, and black. 

 The outside bark or rind, the Peridium, must be examined to note 

 its peculiarities. Some kinds have one or more inner coats. On 

 section the character of the internal substance, or Capillitium, will 

 be seen. Puff-balls have a homogeneous flesh until arriving at 

 maturity, when the substance develops into a mass of dust 

 (Spores), which are ejected by the top of the Peridium bursting. 

 Terms already given will be used in describing these forms. 



AMORPHOUS TYPES. Of these we shall have occasion to 

 notice principally the Tremellini. They are shapeless, jelly-like 

 bodies, mostly parasitic. Habitat, colour, and other particulars 

 have to be observed. 



After this explanation of the typical forms of Mushrooms, that 

 is, of such Fungi as come within the scope of this work, we may 

 now go on to the Classification of them.
