It contains 3 large and 2 small fructifications, one of the latter 
2 X 3 mm. in diameter, the other 4 х 5 mm. "They have been 
preserved in aleohol since 1900 and probably are somewhat 
en. When collected they were probably about the age of 
those examined by Fischer. In the smaller specimen the cavities 
are filled with cells, somewhat irregular on account of mutual 
pressure, which expand to a spherical form when treated with а 
dilute solution of potassium hydroxide. А further study shows 
them to be spores (?) borne acrogenously on short branches of 
curved or zig-zag hyphae, or sometimes terminally on large hyphae 
springing from the trama (see pl. 11, fig. 10). When closely 
packed together they appear in rows, reminding one of the ap- 
pearance of aecidiospores of the Uredinales. Ав the only material 
available was no longer viable, whether these organs are true 
Spores must remain in doubt for the present. 
Secondary spore forms have not been reported very frequently 
in Gasteromycetes. Fischer! has reported cells which he called 
gemmae in Sphaerobolus, and Eidam? and Brefeld? found that 
oidia are produced in poorly nourished cultures of the Nidulari- 
асеае. In the Hymenomycetes most of the literature has been care- 
fully reviewed by Lyman, Zeller* and Snell,* who show that other 
Spore forms are much more common in these fungi. We’ have 
already noted conidia-like cells produced at the surface of Arc- 
angeliella caudata Z & D., although we did not attempt to germi- 
natethem. Тһе spores of the present fungus resemble the basidio-
