120 NATUEAL HISTOEY BULLETIN 



On half-buried branches and sticks in woods, Iowa City and 

 Mt. Pleasant. 



A large species very conunon on decaying sticks in woods in 

 the spring. A number of the plants may often be found attached 

 to a small stick standing upright in a row. They are at first 

 club-shaped, black structures, hollow in the center, finally open- 

 ing by a star-shaped aperture at the apex, when mature leaving 

 the margin notched. In Engler-Prantl Natiilichen Pflanzenfam- 

 ilien this species is included with the subgenus Geopyxis and 

 there seems to be some difference of opinion as to whether this 

 plant should be included with that subgenus, which is now treat- 

 ed as a genus, or allowed to remain where it is.*
