SECTION LENTUS. 



PSEUDO-PERENNIS. Stipe dark or black. Pileus densely 

 covered with appressed pubescence, faintly zoned, with narrow, 

 glabrous zones. Known from a single collection at Berlin from Africa. 

 Though the plant has no relations, it has a general resemblance to 

 Polystictus perennis. 



46. PORES LARGE. 



Some of these might be placed in Favolus to probably better 

 classification. 



a. WHITE. 



FAVOLOIDES (Fig. 470). Known only from one specimen 

 from Africa, in alcohol at Berlin. A very marked species with thin, 

 white, umbilicate pileus, long, slender stem, and large, white, favoloid 

 pores.

Lentus favoloides. Lentus partitus. Lentus nanus. 



NANUS (Fig. 472). Known from one collection from Algeria 

 at Paris. A little species growing in the sand. Spores are globose, 

 4-5, hyaline, smooth. Color seems to me to have been white though 

 described as pale yellowish. 



RHIZOPHILUS. Collected by Patouillard. Common in Tunis, 

 attached to grass culms. Very similar to cryptopus of the United 

 States but has larger pores and spores.
