when dry ; pileus covered with a dense coat of short down 

 pnrplish-brown towards the margin, often greyish-white near 

 the line of attachment, irregularly zoned ; hymenium dark 

 bro^vn, often tinged purple, corrugated behind, almost even to 

 Avards the margin ; spores subglobose, about 4 /x diameter.

At first resupinate and spreading widely, but easily detached, 

 then broadly reflexed and dimidiate, 4-6 cm. long, 2-4 cm 

 broad ; very tough and pliant when moist. Distinguished from 

 species of Auricularia by the hymeniiim being covered with 

 short, irregularly arranged, radiating ribs, giving it a wrinkled 

 or corrugated appearance. 



48. Grandinia, Fries. 



Resupinate ; thin, incrusting, hymenium minutely papillose or 

 granulose, covering the entire exposed surface. 



Grandinia, Fries, Epicr., p. 527. 



When examined under a low power of the microscope, the 

 tips of the minute granules covering the hymenium are usually 

 found to be indented.

White or with a pallid or yellow tinge, irregularly effused, 

 sometimes for several inches, closely adnate, thin, crustaceous, 

 rather mealy at maturity ; warts crowded, subglobose, miniite, 

 often collapsing at the apex, unequal.

Thelephore^, 



The fungi constituting this group show less difierentiation and 

 division of labour than is observable in the preceding groups. 

 In the simplest forms the entire plant is resupinate or attached 

 to the matrix at every point, and the upper surface is ever}^- 

 where covered by the hymenium, with the exception of the 

 silky or fibrous margin, which is the youngest or growing portion. 

 When the fungus becomes partly free from the matrix or sub- 

 stance upon which it is growing, then the differentiation of the 

 usually more or less membranous expansion is obvious. The 

 ujider side, which is turned away from the light, is covered with 

 the hymenium or spore-bearing portion, whereas the upper 

 surface is completely sterile and ixsually more or less velvety or
