ADDENDUM. 



Further information regarding the following two species has 

 come to hand since the preceding was in type. 



POLYPORUS FUMIDICEPS. I have received a specimen from 

 Mr. L. Romell, Stockholm, having come to him from Schenectady, 

 N. Y., and it was the first specimen I have gotten of the species. It 

 is exactly the same as Polyporus tephroleucus to the eye, but differs 

 in having ovate, transparent, guttulate spores, 3> x 5. The spores of 

 tephroleucus are allantoid, I>2x5. As the plants are so similar, I 

 have gone over the spores of all my collection labeled Pol. tephro- 

 leucus and did not find any that were not correctly determined. All 

 have allantoid spores. One must be on their guard, however, to dis- 

 tinguish fumidiceps from tephroleucus, for it is only a slight spore 

 difference. 



POLYPORUS AMYGDALINUS is one of the rare Southern 

 species, known only from the old, discolored types at Kew. I was 

 therefore particularly glad to receive a specimen which agrees with 

 the original account, from R. P. Burke, Montgomery, Ala. We have 

 more pleasure in getting an old species straight than we have in pro- 

 posing a thousand so-called "new species." 



Polyporus amygdalinus we would describe as follows: Surface 

 soft, dull, pale yellowish (or brownish now) with darker innate fibrils. 

 Context soft, spongy, punky, light, pale yellow (Salmon buff). Pores 

 and pore tissue white. Mouths small, round or irregular, white. 

 Spores not found except small, globose, conidial spores. 



This species is not in the body of this book as little could be 

 told from the old, effete type at Kew. I would enter it in Section 87. 

 The contrast of the white pore tissue and yellow flesh is a feature 

 unknown to me in other species. Ravenel states it has an odor of 

 bitter almonds when fresh, hence the name.
