POLYPORUS (AMAURODERMUS) PAPILLATUS (Fig. 773), 

 FROM REV. C. TORREND, BRAZIL. Pleuropodial. Pileus 6 x 10 

 cm., 6 mm. thick, with dull (not laccate), rugulose, radiate surface, 

 brown, with tubercular, uneven, dull surface. Context and pore 

 tissue concolorous, hard, dark cinnamon brown. Pores minute, with 

 papillate, brown mouths. Spores glo- 

 bose, or slightly piriform, 10 mic., pale- 

 colored, smooth. 



The pores seem to be developed in 

 areas, and the papillate mouths (Fig. 

 774 enlarged) are quite curious. In fact, 

 a similar appearance led Berkeley to 

 classify Polyporus Sprucei as Poro- 

 thelium (sic). (Cfr. Stipitate Poly- 

 poroids, p. 110, fig. 404.) 



This belongs to section 7 of the 

 Stipitate Polyporoids, and we believe it 

 is only a form of Polyporus Chaperi, 

 differing in its rugulose, striate (not 

 zoned) pileus, its papillate pore mouths, 

 and its stem, solid, not having sterile branches. When I first investi- 

 gated the subject, there was but one specimen of Polyporus Chaperi 

 known, which was at Paris. It came from Cuba. (Cfr. Stipitate 

 Polyporoids, Fig. 406.) Then I got a specimen from Gustavo Peckolt, 

 Brazil, agreeing exactly with the type in everything. Then I saw in 

 Ellis' herbarium a specimen from Smith, Nicaragua, which had a 

 lateral stipe, but every other feature exactly the same as Polyporus 

 Chaperi and surely same species. It was named Polyporus avellaneus 

 by Murrill. Then I so referred a specimen (sent without stipe No. 44) 

 from Rev. C. Torrend, Brazil. There is evidence of its having had a 

 lateral stipe. Then I got this specimen, which, while it differs from 

 the four previous specimens in several important characters, I still 

 believe it is only a form of Chaperi. 



CORDYCEPS OF JAPAN. In Matsumura's list there is a 

 record of but one species of Cordyceps from Japan. There are four 

 species known, and no doubt a great many that are not known. I 

 trust my Japanese correspondents will pick up and dry every speci- 

 men of a Cordyceps they note and forward to me. A few words in 

 regard to the collection of Cordyceps will not be amiss. Cordyceps 

 have only to be picked up and dried; but, as the host is usually 

 buried, care should be taken to dig out the host and forward it, 

 attached to the Cordyceps. They change very little in drying, so it 

 is not necessary to send them in alcohol. Simply lay them aside 

 for a few days and dry them, wrap in tissue paper, and place in a 

 little box and mail to my address. If you are an entomologist and 

 know the name of the host, it would add much to the interest if the 

 name of the host is stated on a piece of paper and enclosed with the 

 specimen.
