GANODERMUS. 



imbedded, giving the effect of black lines in a section. Pores minute, 

 hard, with yellow mouths. Spores 5x9, obovate, smooth, with 

 many smaller, 4x6. 



This was received by us from C. B. Ussher, Java, and at first we 

 were inclined to refer it to Fomes leucophaeus, to which it is similar 

 in crust and general appearance. The narrow context zones and paler 

 context, as well as the interposed, resinous layers in the context and 

 the minute, hard pores, are features never found in the common 

 Fomes leucophaeus. I have similar plants from Java and Brazil, 

 excepting that the context zones are not evident. Also a very doubt- 

 ful collection from Madagascar, which, while the same as to pores 

 and context, has a smooth, shiny, black crust. 



SPECIMENS. Java, C. B. Ussher (type), Dr. van Leeuwen; Brazil, P. Pio Buck (not typical) ; 

 Madagascar, Henri Perrier de la Eathie (very doubtful). 



FOMES KONINGSBERGIL Pileus applanate, thin, 2-3 cm. 

 thick, mostly reduced to the base, and most specimens have a false 

 stipe-like base. Surface smooth, uneven, nonlaccate, varying from 

 pale brown to fuliginous. Context dark brown (bay brown), with 

 layers of imbedded, resinous tissue. Pores minute, with thick walls, 

 hard, heavy. Pore mouth white. Spores 6 x 10, smooth. 



A single, but very abundant^ collection was received from Dr. 

 J. C. Koningsberg, Java. We referred it with doubt to Fomes leuco- 

 phaeus (cfr. Letter 38). We sent it to Europe and it was referred to 

 Polyporus gibbosus, of which nothing is known excepting Xees' 

 figure. To us it has no resemblance to that figure. It appears rare 

 in Java, at least we have seen no others than the type. 



SPECIMENS. Java, Dr. J. C. Konigsberg, a very abundant collection (type). 



SECTION 75. STIPITATE FOMES OF THE SECTION GAXODERMIS. 



In our pamphlet on the Stipitate Polyporoids we took the ground that there 

 were no truly stipitate species of Fomes. Specimens we had seen we referred to 

 sessile species, believing them to have accidental stems. We have received several 

 specimens from the tropics that certainly have normal stems, and we are convinced 

 that it is a good specific character. In one species from Java both stipitate and ses- 

 sile specimens occur, but that does not necessarily void the value of the character. 



Should we revise the subject, we would make this Section 75, the second sec- 

 tion of stipitate polyporoids. 



FOMES TESTACEUS. Pileus with a lateral, deformed stipe. 

 Crust smooth, not laccate, castaneous brown, variegated, zoned. 

 Context bay brown. Spores minute, with white pore mouths. Spores 

 6x10, smooth. 



We use the name in the sense of Patouillard to avoid inventing 

 a new one. In the sense of Leveille, the "type" has no stipe, and we 

 believe it to be only the usual tropical form of Fomes applanatus. 

 We have three collections that we refer here our own, Samoa, 

 Machardo, Perak, and Rev. Rick, Brazil. The two former have
