the base of the pileus. Pores minute, alutaceous. It is the first 

 time we have seen the species. So many of Fries' African specimens 

 have disappeared, that the only thing to do is to fit the names to the 

 species where they fit the best. It belongs, however, in Section 22 

 of my pamphlet, not the grammocephalus section. The specimens 

 disagree with the description, for pores do not extend to base of stipe, 

 but in one of the specimens there is an indication of pores on the 

 stipe. 



POLYPORUS UNITUS, FROM W. SMALL, AFRICA 



(Fig. 1045). Pileus infundibuliform, thin, fleshy, dark reddish 

 brown. Surface glabrous, 

 unicolorous, slightly stri- 

 ate, ridged. Stems several 

 from a rooting base, brown, 

 about an inch long, united 

 above to form one perfect 

 pileus. Pores fleshy, dark, 

 small, but usually elongat- 

 ed. Cystidia none. Spores 

 abundant, compressed glo- 

 bose. 10 x 12, hyaline, 

 smooth. 



This is based on a 

 single specimen, and it is 

 difficult to believe that it 

 is the usual manner of 

 growth. If we knew any 

 species from which it could 

 be derived, we should con- 

 sider it an accidental 

 growth. But it seems pe- 

 culiar that it should send

up several stems from a rooting base, which produce one perfect, 

 infundibuliform pileus. It seems that is the character of the species. 

 It sometimes happens, when two different plants grow contiguous, 

 that the pilei fuse, but generally clearly show the line of joining. This 

 plant with several stems (5) from one root, forms a single, perfect 

 pileus, with no marks or indications of not being one plant. The 

 species is entered in our Section Lentus 45c. 



PTYCHOGASTER LUCIDUS, FROM REV. C. TORREND, 

 BRAZIL (Fig. 1046). We do not know that Polyporus lucidus ever 

 takes, in temperate regions, a Ptychogaster form, but Rev. Torrend 

 sends the normal, tropical form, with the Ptychogaster form growing 

 from the same mycelium. We gave in Mycological Notes, Polyporoid 

 Issue, No. 2, page 31, an account of Ptychogaster albus, which in 

 Europe is the most frequent Ptychogaster known. No one has 

 explained why or under what conditions the Ptychogasters are formed. 

 All that is known is that certain specimens, instead of developing the 

 normal spores, and basidial spores, produce in great quantities conidial
