WESTERN POLYPORES 3 



Tribe 4. DAEDALEAE. Hymenium annual, very rarely perennial, coriaceous to 

 woody, variable in size; surface anoderm, hairy or glabrous, variously marked; 

 context white or brown, fibrous, woody, or punky; hymenium exceedingly 

 variable, normally labyrinthiform or lamelloid, but often poroid or even irpici- 

 form, never stratified; spores smooth, brown or hyaline. Poroid and irpiciform 

 plants of this group are difficult to separate from certain species of Polyporeae, 

 forms of Daedalea confragosa in particular being troublesome to the beginner. 

 On the other hand, there is little to cause confusion between this group and 

 the Fomiteae, if we except the single distinctly perennial species of Daedalea 

 and the daedaleoid forms of Porodaedalea. 



Context white or wood-colored. 



Hymenium labyrinthiform, often becoming lamellate or 



irpiciform. 



Hymenium very soon becoming irpiciform. 26. CERRENA. 



Hymenium rarely becoming irpiciform and then 



not until maturity. 27. DAEDALEA. 



Hymenium lamellate from the first, not becoming 



irpiciform. 28. LENZITES. 



Context brown. 29. GLOEOPHYLLUM. 



i. CORIOLUS Qu61. 



Hymenophore annual, epixylous, sessile, usually zonate, ano- 

 derm, hairy or glabrous; context thin, white, flexible, fibrous, 

 leathery; tubes thin-walled, white, at length splitting into irpici- 

 form teeth in several species, mouths polygonal or irregular; 

 spores smooth, hyaline. 



Surface of pileus zonate. 



Tubes more or less entire, at least until the hymenophore 



is quite old. 



Surface marked at maturity with conspicuous gla- 

 brous zones of different colors. i. C. versicolor. 

 Surface clothed entirely with a conspicuous hairy 



covering. 2. C. nigromarginatus. 



Tubes soon breaking up into long, irpiciform teeth. 3. C. abielinus. 



Surface azonate, smooth, subglabrous, white. 4. C. washingtonensis. 



i. CORIOLUS VERSICOLOR (L.) Quel. 



Pileus densely imbricate, very thin, dimidiate, conchate, 

 2-4 X 3-7 X 0.1-0.2 cm.; surface smooth, velvety, shining, 

 marked with conspicuous, glabrous zones of various colors, 

 mostly latericeous, bay, or black; margin thin, sterile, entire; 

 context thin, membranous; tubes punctiform, less than I mm. 

 long, white to isabelline within, mouths circular to angular, 

 regular, even, 4-5 to a mm., edges thick and entire, becoming 

 thin and dentate, white, glistening, at length opaque-isabelline 

 or slightly umbrinous; spores allantoid, 4-6 X 1-2 /*.
