spores, borne direct from the hyphae, and that the pores are oblit- 

 erated. Sometimes these spores are borne in such numbers that the 

 specimen is simply a mass of spore powder, with not enough hyphae

to hold them together. The shape of these spores is never, as far as 

 I know, the same as that of the normal spores. In this form, Ptycho- 

 gaster lucidus, they are deeply colored, globose, smooth and vary in 

 size from 4 to 12 mic. Hardly any two are the same size. 



GEOGLOSSUM HIRSUTUM, FORM DEPAUPERATUM, 

 FROM J. UMEMURA, JAPAN (Fig. 1047). This is a little form, 

 hardly a cm. high, growing on dry ground 

 in moss. Notwithstanding its small size 

 and different habits, I should prefer to 

 refer it as a form of Geoglossum hirsutum. 

 The spores (colored, no mic. 15 septate), 

 paraphyses, and setae are the same. Geo- 

 glossum hirsutum is our most frequent 

 species in the United States, but with us 

 I do not know it to take this depauperate 

 form. The photograph we present was 

 made in situ by Mr. Umemura. Fig. 1047. 



POLYPORUS CONCHATUS, FROM P. VAN DER BIJL, 

 SOUTH AFRICA (Fig. 1048). Largely resupinate, but with re-

Surface dull mat. Pores medi-

the Apus Polyporus, and closely 

 related to Polyporus rugoso-porus. The color is entirely different.
