Villose, covered with long weak hairs. 

 Viscid, covered with a sticky exudation. 

 Wrinkled, surface conti*acted and crumpled. 

 Zoned, concentric bands of colour on surface. 



THE CUTICLE. This is the skin, peel, or external epidermis 

 of the upper surface of the Pileus. Its aspect is generally 

 described by sundry of the foregoing terms. It is also spoken o 

 as being Adherent, or Adnata, when firmly attached to the flesh ; 

 Separable, when it can readily be pulled off ; and Areolate, when 

 broken up into little angular spaces. 



THE MARGIN. The boi-der or outward edge of the Pileus. 

 Some terms describing it, not already included among those 

 previously given, are the following : 



Arcuate, arched and curved in outline. 



Blunt, thick and rounded. 



Broken, jagged and fissured. 



Depressed, directed downwards, away from the disc. 



Even, of clean and equal outline. 



Flanged, turned out flatly, like the brim of a vessel. 



Flexuose, of wavy outline. 



Grooved, deeply and irregularly furrowed. 



Incurved, folded flatly and slightly downwards upon itself. 



Involute, rolled tightly in upon itself. 



Patent, spreading directly outwards. 



Pellucid, clear and translucent. 



Pendulous, hanging loosely down. 



Plicate, plaited lengthways in little folds. 



Pubescent, covered with fine down. 



Split, cracked and fissured. 



Striate, finely streaked, imperceptibly sulcate. 



Tomentose, covered with very evident down. 



Waved, irregularly bent in outline. 



THE SCALES. These are flattened flakes formed upon the 

 surface of the Cuticle in some species, and also sometimes covt-i'- 

 ing the Stem externally. Some terms already given may be used 

 in describing them ; others are the following : 



Concentric, when arranged round the centre of the disc thickly, 

 becoming large and scattered at the Margin.
