Corticium porosum, B. and Br., Ann. Nat. Hist., ser. 4, xi. 

 p. 343 ; Mass., Mon. Thel., p. 138. 



On wood. Broadly and irregularly effused, generally 

 loosely fibrillose and spongy, with variously-sized pores or 

 lacunae on the surface ; vaguely spreading on the surface of 

 wood and passing on to surrounding bodies on the ground, 

 sometimes forming a thick felt with scattered tufts of 

 sporophores, as in the imperfect forms oi Gort. arachnoideum ; 

 sometimes passing from the above stage, into a compact, con- 

 tinuous, waxy hymenium of an ochraoeous or pale cinnamon 

 colour when dry. The hyphae are 4-5 /x. thick, and fur- 

 nished with numel-ous clamp-connections; resembling in 

 habit Gorticium porosum, differs in the spores and in the 

 hymenium not being cracked when dry. 



Corticiuni radio sum. Fr. 



Subrotund, thin, closely adnate, margin white, fibrillose, 

 radiating ; hymenium dingy ochraoeous, not cracked when 

 dry ; spores subglobose, 5-6 fi. diameter. 



Gorticium) radiosum, Tries, Hym. Eur., p. 649 ; Mass., Mon. 

 Thel., p. 139. 



Aihelia ochracea, Pers., Myc. Eur., i. p. 84. 



Gorticium radians, B. and Br. 



On rotten wood. Somewhat resembling G. lacteum in 

 habit, but distinguished by the dark ochraoeous hymenium, 

 which does not crack when dry. 



** Hymenium brightly coloured. 



Corticium roseolum. Mass. 



Very hroadly effused, indeterminate, very thin and in- 

 separable from the matrix; hymenium continuous, bright 

 rose-coloured, becoming pale; spores, subglobose, apiculate 

 7 X 8-9 11. 



Gorticium roseolum, Massee, in Mon. Thel., p. 140. 



On old worked wood. Spreading irregularly for many 

 inches on smooth wood, exceedingly thin, adglutinated, 

 margin vague ; hymenium not cracked when dry, at first of 

 a bright rose-colour, then hecoming pale and persisting as 

 pale ochraoeous, with only a tinge of rose when dry. Spores 

 very abundant, resembling in habit Peniophora incarnata
