Jackson: Sorosporium Ellisii Winter 149 



the small number of collections made, probably accounts for this 

 species having been so long overlooked. The type specimen has 

 been deposited in the herbarium of the New York Botanical Gar- 

 den. The Alabama material diners from the type in its slightly 

 darker spores. The Ohio material has not been seen, but is here 

 included on the authority of Clinton (/. c). 



The writer here acknowledges the kindness of the officials of 

 the New York Botanical Garden in giving him unrestricted use of 

 their library and herbarium.
