1897] ZYGOMYCETES, SYNCEPHALASTRUM AND SYNCEPHALIS II 
Of the new species of Syncephalis previously referred to, 
three may be characterized as follows: 
Syncephalis Wynnez, nov. sp. Plate /, figs. 5-12. 
_ Color white turning to pale straw color. Fertile hyphe 
erect, straight, usually septate at the base, with well-marked 
rhizoids, tapering slightly towards the tip, distally enlarged, not 
abruptly, into a comparatively small head from all portions of the 
surface of which are produced secondary sporophores, the latter 
clavate, swollen at the tip, whence each gives rise to about a dozen 
sporangial filaments from each of which are produced two spores. 
Spores irregularly long-oval, usually slightly asymmetrical, 
involved at maturity ina mucus drop, 16-19 by 6. Second- 
ary sporophore about 25m long. Fertile hypha 400-475» long, 
the head including spore zm set about 100—120p in diameter. 
On Wynnea macrotis Berk., Cranberry, North Carolina. 
This species was found in a single instance, growing out of doors on a 
large clump of its remarkable host, which appears to be not uncommon in 
the Carolina mountains, and on which it seemed to be truly parasitic, grow- 
ing not very densely and inducing a rapid decay in the large spoon-shaped 
apothecia, Attempts to cultivate it on potato-agar were unsuccessful, and no 
zygospores were found in the material examined. The species is especially 
noteworthy from the marked differentiation of its secondary sporophores, to 
which reference has been made above. 
Syncephalis pycnosperma, nov. sp. late II, figs. 32-38. 
Vegetative hyphe slender with nodular anastomoses. Fer- 
tile hyphe rather short and stout, commonly constricted at the 
basal septum, distally not abruptly enlarged to form a small 
head from all parts of which are produced numerous clavate sec- 
ondary sporophores, the latter rarely furcate, distally gradually 
expanded and two to four-lobed, each lobe giving rise to a spo- 
rangial filament producing invariably three spores. Spores sub- 
rectangular or angular in section, thick-walled, involved in 
mucus at maturity, 13-16 by 7-Su. Fertile hyphae 300-350 by 
25m (towards the base) to 17 (towards the apex). Secondary 
sporophores about 24» long. 
On dung of mice (New Haven, Conn.) and of sheep (Cam- 
bridge, Mass.).
