In one specimen only amongst a considerable number 

 was any sign. of a sterile base found, and then it took the 

 form of a slender process emerging from a depression. 



GYMNOMYCES SEMINUDUS, Mass. et Rod. 

 ("Kcw Bulletin," June. 1898.) 



Very similar in form, size, and colour to the last, but 

 of firmer consistency. Peridium thin, delicate, and silky. 

 Gleba not very fragile, spaces small and irregular. Spores 

 ccliinulate. 11-12 micron. 



3. HYSTERANGIUM, Vitt. 



Peridium distinct, and not continuous with the trama. 

 Gleba gelatinous, developing contorted hymenial cavities. 

 Spores smooth, elliptical. Sterile base seldom present. 



HYSTERANGIUM FUSISPORUM, Mass. et Rod. 



("Kew Bulletin, ■ June, 1898.) 



Subglobose, irregular, pale straw coloured, 1.5-2 cm. 

 Peridium very thin, membranous. A small sterile base is 

 sometimes present. Gleba rather dense, pale, densely 

 packed when mature with minute convoluted spaces. Spores 

 smooth, broadlv fusiform, with narrow acute ends, hvaline, 

 20-22 y. 8 micron. 



HYSTERAl^GIUM MEMBRANACEUM, Vitt. 



Irregularly spherical, white but readily marking with 

 indigo if touched when young, very delicate consistency 

 when fresh. Peridium thin, dry. white almost floccose. 

 Gleba white when young, marking with indigo where cut. 

 becoming pale brown when old. Spaces ver\' small and 

 nuniprous. convoluted. Sterile base present, and extend- 

 ing l)elow into a root-like process. Spores elliptic, smooth, 

 sometimes rather pointed at one end, 12x5 micron.
