SECTION LENTUS. 



This section generally has mesopodial stipes. They are thinner, more pliant, 

 or coriaceous than the section Ovinus. Also they are mostly epixylous in 

 habitat. All as far as known have pale context hyphae and white spores. 



45. LENTUS. PORES SMALL. 



a. WHITE. 



TRICHOLOMA (Fig. 466). White, strongly marked with ciliate 

 hairs on the margin when young, but they are detersive. Pileius de- 

 pressed in the center. Spores 4x6, hyaline, smooth. Frequent in 

 tropical America. 



CRYPTOPUS (Fig. 467). Growing attached to grass stems in 

 western United States. Similar to rhizophilus of Tunis, but has smaller 

 pores and spores. 



CORYLINUS. Only known from illustration (Viv. t. i) from Italy, but 

 seems very distinct. 



LEPTOCEPHALUS. Only known from an old illustration (Jacq. Misc. i, 

 t. 12) but seems quite characteristic. In short, it is elegans without a black stipe, 

 (albiceps, see page 180. Specimens with uncolored stems would be sought here.) 



b. GRAYISH OR FULIGINOUS BROWN. 



BRUMALIS. Stipe and pileus fuliginous. Pores small but elon- 

 gated, white. Common both in Europe and the United States, on 

 branches, late in the season.
