PORES WITH THIN WALLS. 



FOMES FASCIATUS (bis.) Surface dull, marked with pale and brown 

 zones, otherwise as the form leucophaeus. The spores of our Java collections are 

 none of them truncate at base, the membrane seeming not so strongly developed as 

 usual. 



This is a tropical form, the name based on a misdetermination by Leveille. 

 We do not think an acknowledged misdetermination has any validity as a name, 

 but use it as we know no other for this form. Formerly we took the original Fomes 

 fasciatus of Swartz in the sense of Fomes marmoratus of this pamphlet, but that 

 view has been disputed by Romell, and owing to the doubt we have abandoned it. 



SPECIMENS. Java, J. C. Koningsberger (two collections). 



FOMES AUSTRALIS. In a narrow sense, this is a tropical form of Fomes 

 applanatus, with a thin context and long pores. 



It is a time-honored custom to refer every Fomes of the section Ganodermus 

 that came, from the tropics to Fomes australis. Murrill varies the proceedings by 

 calling it Fomes tornatus, but the idea is the same. In the sense of Fries (type at 

 Kew) Fomes australis was based on a form of Fomes applanatus with thin context, 

 hence had "praelong" pores, but on comparison with the type form in Europe, we 

 find it is in other respects exactly the same. The "type specimen," however, does 

 not agree with Fries' description where it was described as having a "shiny, laccate 

 crust," but it is just the contrary. It is a mistake to consider that Fries had any 

 definite species, distinct from Fomes applanatus which he named Fomes australis, 

 or that any one else has had in connection with this name. Fomes australis is a 

 convenient name to which to refer the tropical forms of Fomes applanatus, but we 

 would restrict it to those that have thin context and long pores. 



SPECIMENS. The following specimens agree with the type in having "praelong" pores and 

 scanty context, but that it is distinct from Fomes applanatus we cannot believe. Japan, A. Yasuda; 

 Natal, A. J. T. Janse; South Africa, I. B. Pole Evans; Congo Beige, Rev. H. Vandegrift; Jamaica, 

 Wm. Kirkland, N. Y. Botanical Garden; New Caledonia, Museum Paris; Philippines, E. D. Merrill; 

 Argentina, Leon Castillon. 



Compare nigricans, chilensis, testaceus, tornatus, scansilis. 



FOMES OROFLAVUS. A tropical form of Fomes applanatus with yellow 

 pore mouths. 



Fomes applanatus, in European and American forms, usually has white pore 

 mouths. A quite frequent plant in the tropics, otherwise the same has deep yellow 

 pore mouths. We have never seen but one specimen from Europe that approximates 

 this tropical form. We have several collections from the United States (particularly 

 California), which we refer to Fomes applanatus (and rarely to Fomes leucophaeus) 

 that have yellow pore mouths, but they are not the deep yellow of the tropical plant. 



SPECIMENS. Australia, Rev. James Wilson; Hawaii, C. N. Forbes. 



FOMES NIGRO-LACCATUS. Tropical forms of Fomes applanatus some- 

 times have a slight, black, resinous exudation on the crust. Such we think should 

 be called Fomes nigro-laccatus\ the only suitable name for them. 



We consider this according to the evident idea that Cooke associated with 

 the name, that is, assuming that he had an idea. The technical "types" (cited) are 

 now endorsed as being two species, neither of them Fomes nigro-laccatus. As Cooke 

 named several collections" Fomes nigro-laccatus when the name was appropriate, 

 we feel he should be credited with correct application of his name, at least in those 

 cases where he applied it suitably. Fomes nigro-laccatus in this sense occurs only 

 in the tropics. There is a specimen at Kew, from Cuba, but most are from Africa. 

 We have it (?) from Japan. 



FOMES GALEGENSIS. Very similar to Fomes applanatus as to pores, 

 context, and spores, but has a hard, thick, smooth, black (cracked) crust. The 

 specimen on which the species is based is in a cupboard at Paris. We have noted
