HYMENOGASTER NANUS, Mass, et Rod. 

 ("Kew Bulletin," June, 1898.) 



Irregularly globose, 1-3 cm. Sooty brown, with a. 

 mucilaginous surface. Periclium rather thick, fleshy, the 

 outer portion gelatinous, separable from the gleba. Gleba 

 firm, light orown, spaces rather lax-ge. Sterile base well 

 deareloped. Spores eilliptie, subobtusef, Ibrown, warted,, 

 14-15 X 8 micron. 



HYMENOGASTER RODWAYI, Mass. 



("Kew Bulletin,'' June, 1898.) 



Ii'regularly globpse generally, 2-3 cm. diameter, pale.. 

 Peridium very distinct, fleshy. Gleba dark brown, sjiaces 

 small and irregular, showing an indistinct tendency to) 

 radiate from the sterile base towards the periphei-y. Sterile 

 base usually conspicuous and giving off branching veins 

 penetrating the gleba. Spores elliptic or lemon-shaped 

 apiculate at one end, longitudinal^" ribbed, ribs simple, or 

 forked and anastomosinsr, strone:, converging at the ends, 

 20 X 10-12 micron. 



HYMENOGASTER ALBIDUS, Mass. et Rod 

 C'Kew Bulletin," Sept. 1901.)

 mycelium. Sterile base rudimentary or absent. Gleba 

 pinkish Avhite, turning light brown when diy, spaces tortu- 

 ous, larger than in H. Rodwayi. Spores elliptic, pointed

 coarsely rugose, pale brown, 21-28 x 14-18 micron. 



HYMENOGASTER VIOLACEUS, Mass. et Rod. 

 (Kew Bulletin," June, 1898.) 



Subglobose, violet and viscid, 2-3 cm. Peridium thim 

 but distinct. Gleba rather firm, brown. Spaces numer- 

 ous, tortuous, about 1 m.m. diameter. Sterile base ob- 

 solete to very distinct in some specimens, a sterile vein
