AURISCALPIUM (Fig. 407). Pileus reniform, the upper sur- 

 face rugulose, zonate, mat. Stipe lateral with a dull crust. Color 

 reddish brown. Spores 6-8, globose, smooth, pale colored. The original 

 Persoonian specimen from Brazil is still well preserved at Paris. Mon- 

 tagne referred here several collections from South America which 

 Berkeley and Patouillard have held to be different. 



PRAETERVISUS (Fig. 408). This is based on a single specimen from 

 Brazil, referred to the preceding by Montagne. As to shape, size, context, color, 

 and spores it is very much the same, but it has larger pores and a thicker. 

 blacker, harder crust. 



OMPHALODES (Fig. 409). Pileus orbicular, with a mesoppdal 

 stem, but rarely perfect, being usually more or less lobed and divided 

 to the stem. Surface glabrous but not laccate, rugulose, more or less 

 zoned. Stipe slender with a mat, dull surface. Pores small, 2 mm. 

 deep. Spores globose, 12 mic., smooth, pale. Abundant specimens 

 were sent to Kew from Spruce, Brazil. All have very much the same 

 general size and stature as our figure. At Paris are much larger, 

 obese (but otherwise apparently the same) specimens from Suth 

 America, called "var. fulvaster."
