 SETAE PRESENT. SPORES COLORED. 



A. Context Light Brown. 



FOMES YUCATENSIS. This is similar in every particular to 

 Fomes rimosus, excepting that it has setae. They are thickened at 

 the base, and pointed. At New York there are specimens from 

 Central America, and at Paris I have noted a specimen from New 

 Caledonia (determined as Fomes rimosus), but which is characterized 

 in the same way. Also from Africa, where it was called Xanthrocus 

 rudis, it being the third time the specific name rudis was applied to 

 an (alleged) Fomes. 



Compare rudis. 



FOMES SARCITUS. Pileus applanate, rather thin, (1^ cm., 

 with thin edge). Surface black, rimose, at length fibrillose, lacerate. 

 Context bright brown (Raw Sienna). Pores minute, with concolorous 

 tissue, but with darker, velutinate mouths. Hyphae deeply colored. 

 Setae, rare. Spores small, 3-3^ mic., globose, deeply colored. 



This species from the West Indies, type preserved in a jar at 

 Upsala. It seems rare, at least there is no additional material in the 

 abundant collection from the West Indies at New York. I have a 

 collection from Trinidad, same on comparison as the type, but the 

 spores are a little larger (4-4^ mic.). 



SPECIMENS. Thos. Langton, Trinidad. 



FOMES OSTRICOLORIS. Pileus large, hard, woody, with 

 obtuse margin. Surface sulcate, black, rough. Context bright yellow 

 brown (ochraceous-tawny). Pores minute, with concolorous tissue 

 and dark purplish, velutinate mouths. Setae abundant, with swollen 

 bases. Spores globose, pale colored, 3>^ x 4. 



This was received from Edouard Luja, Congo, Beige. In the 

 grosser features it is very similar to Fomes torulosus, from which it 

 differs in colored spores. The velutinate, dark purple pore surface is 

 a marked feature. 



FOMES RHABARBARINUS. Pileus applanate, (5x6x1 

 inch), with a thick, hard, smooth, ridged, black crust. Context light 

 yellow brown (near ochraceous tawny), hard, woody. Pores very 

 minute, with concolorous tissue, but brown mouths. Setae, short, 

 thick, projecting 10-12. Spores not found. (The hymenial elements 

 are all deeply colored, and the spores are probably colored, though 

 it is strange they are not in evidence.) 



This is known from a single specimen at Kew. When Berkeley published it 

 he overlooked the label (attached to the underside), and stated that it had no label 

 and was probably from Brazil. The label (by Klotzsch) states it was collected by
