Polystictus formosae. 



POLYSTICTUS FORMOSAE, FROM A. YASUDA, JAPAN 



(Fig. 899). Pileus thin, pale, glabrous, rugulose, with narrow darker 

 zone. Context white. Pores large, rigid, angular, shallow. 



A single specimen, No. 391, from Formosa. The pores are ex- 

 actly the same as those of Polystictus Persoonii, and while I can not 

 assert it, I have a feeling that it is an extreme form of this species. 

 Type Yasuda, 391, Formosa. 



BOVISTELLA OBLONGISPORA, FROM MISS A. V. DU- 

 THIE, SOUTH AFRICA. Peridium thin, glo- 

 bose 1-2 cm. in diameter. Cortex furfuraceous. 

 Gleba compact, olive then umber. Sterile base 

 none. Capillitium deep colored, long, intertwined, 

 much branched, about 3 mic. in diameter. Spores 

 (Fig. 900) regular 4x6 mic. oblong, dark colored, 

 smooth, with a short, thick, permanent, subhya- 

 line pedicel 4-5 mic. long. 



This species belongs to the 4th section of the 

 genus (Myc. Notes, page 285) and is the only 

 species of Bovistella known with oblong spores. 

 The plant is quite similar to Lycoperdon oblongisporum in several 

 respects, but the latter does not have pedicellate spores. 



POLYPORUS OBNIGER, FROM DR. F. STOWARD, AUS- 

 TRALIA (Fig. 901). 

 Pileus (about 2x3x7 

 cm.) with a short lateral 

 stipe, thick, rigid. Sur- 

 face smooth, black. 

 Context pale isabelline. 

 Pores minute, round, 

 with greyish cinerous 

 mouths (when dry), de- 

 current to base of stem.
