CONTEXT AND PORES COLORED. 



POLYPORUS INAMOENUS. This is an indurated subfomes form of Poly- 

 porus gilvus. Sometimes it shows distinct pore layers. Polyporus gilvus takes this 

 form more commonly in warm countries, but we have specimens from California 

 and Dakota. 



SPECIMENS. California, L. C. C. Krieger; South Dakota, Dr. Brenckle; Uruguay, Dr. F. 

 Felippone; Australia, E. Jarvis; New Caledonia, Museum Paris; Mauritius, P. Koenig; India, H. 

 Val. Ryan.

 Polyporus Hookerii. 



POLYPORUS HOOKERII (Fig. 683). Hooker made a collection in India 

 which is an extreme form of Polyporus scruposus, to which Berkeley referred it as a 

 "var." The pileus, instead of being simply tubercular, rough as in the American and 

 African forms, is strongly fibrillose-strigose (Fig. 683). If standing alone, it would be 

 a strong species, but intermediate collections connect it with the ordinary form of 

 Polyporus scruposus. There is also a specimen of this plant at Kew from Australia, 

 and we have it from Mexico. 



SPECIMEN. Mexico, Dr. S. J. Bonansea. 

 Compare stabulorum. 



POLYPORUS SPURCUS. Pileus thin, applanate, rigid, with a thin, rugulose, 

 glaucous crust, distinct from the context. Context cinnamon brown, hard. Pores 

 minute, with darker mouths, concolorous as to tissue with the context. Setae abun- 

 dant, slender. Spores hyaline, small. 



Polyporus spurcus is known only from the type at Paris from Guadaloupe. 

 With the same context color, setae, and spores as Polyporus gilvus, it differs in having 

 a distinct, glaucous crust. It surely is not Polyporus licnoides as recently referred, 

 nor is it the same as Polyporus callimorphus as recently referred, which is licnoides. 

 There is a possibility that when Polyporus spurcus is better known it will be found to 

 be a Fomes. 



POLYPORUS ILLICICOLA. Named from Japan, is a thin, soft form of 

 Polyporus gilvus, which when young is a bright, yellow color that it loses with age. 

 It was named and misdescribed by Hennings as having spores 8-10 x 13-16. They 

 are 3 x 3>. We have also the same form from Japan. 



SPECIMENS. Japan, Dr. A. Yasuda. 



POLYPORUS MARCUCCIANUS. Pileus applanate, with soft, brown sur- 

 face. Context dry, soft, light, floccose. Pores small, round. Setae slender, 

 numerous. Spores globose, hyaline, 4-4X mic.
