SECTION LIGNOSUS. 



color. I am told that it is caused by a Hypomyces, but I am unable to detect 

 the mycelial threads of a parasite in the tissue and it does not seem to explain 

 it to me. The spores which I think are conidial are subglobose, hyaline, apiculate, 

 and distinctly rough. I have a specimen from L. Damazio, Brazil, and there 

 is one at Kew from Georgetown, British Guiana. 



PAUL/EN SIS. Known by a single specimen from Brazil at Berlin. If not 

 the same it is quite close to pansus. It has a well developed, ligneous, white 

 context and hyaline globose, 6-7, smooth spores. Otherwise it seems the same 

 as pansus, particularly in its peculiar, zoned surface. 



HYPOPLASTUS. Surface dark, almost black, faintly zonate. 

 Stipe black, smooth, with a resinous crust. Context pale isabelline. 

 Spores not found, but I think they are white. The type is a mesopodal 

 plant, but Berkeley refers 'here (and I think correctly) two flabelli- 

 form specimens. All are from northern South America. This plant 

 differs from all others in this section in its laccate stem. While I 

 have found no spores, I believe it does not belong to the section 

 Ganodermus. 



CAMERARIUS. Pileus reniform, smooth, even, glabrous, beau- 

 tifully zoned with narrow, regular, concentric, brown zones. Stipe is 

 pleuropodal (in one specimen, probably the same, it is mesopodal) 

 with a dull crust. Context pale isabelline, probably white when fresh, 

 2-3 mm. deep, almost reaching the crust. Spores not found, probably 

 white. Several specimens of this are at Kew, all from northern South 

 America. 



ARENATUS. Pileus flabelliform, subligneous, incurved in dry- 

 ing. Surface gray, strongly zoned. Context white. Stipe lateral, 

 short, thick. Pores minute, rigid, pale. A strongly marked species 

 from New Guinea found in the Museum at Paris. 



RHIZOMATOPHORUS. Pileus flabelliform, thin, with smooth, 

 pale isabelline surface. Pores minute, concolorous. Stipe slender, 

 long, attached to a slender, long rhizome. A single specimen of this 

 is at Berlin, from Brazil. It is endorsed "=Trametes Rhizophorae" 

 which is surely an error. 



PUDENS. Known from a single, young, half specimen at Kew, from India. 

 It has a long rhizome and in some respects it resembles the preceding. I think 

 not much can be ascertained from this single, immature type, but it may be 

 recognized through comparison if found again. 



POLYDACTYLUS. This is known from one apparently abnormal speci- 

 men from Brazil. It has white context and a lateral stipe which divides and 

 bears on the ends of the branches little, orbicular, disc-like pilei. The surface 

 is minutely velutinate, brown, and marked with metallic zones. In its general 

 nature I think it is related to corrugis of Europe. 



ATRO-PURPUREUS. This is also known from a single specimen from 

 Brazil, and has the same context color and surface marking as the preceding. 

 The pilei are thinner and borne in a different manner. The pore mouths are 

 white, but when bruised are reddish. I think the plant is badly named.
