are the exception rather than the rule." * This material, while 

 agreeing with the original description in taxonomic characters, 

 differs materially in the matter of distribution, being very local in 

 occurrence and confined in the main to the upper fourth of the 

 host, upon which it produced no dwarfing effect. 



2. Hydrogera Kleinii (van Tiegh.) Kuntze {Pilobolus Kleinii 

 van Tiegh.). 



During September and October last, the form spliaerospora 

 Grove of this species was abundant on horse dung in the vicinity 

 of Lafayette. As the only point of difference between this and 

 the typical form of the species is the shape of the spores obser- 

 vations were made to determine the taxonomic value of this 

 character. The sporangia which mature first from any spore- 

 germination contain globular spores while those which mature 

 later contain the typical elliptical spores. The fresher the sub- 

 stratum the greater is the proportion of spherical spores. The 

 form in question is therefore not taxonomically distinct from the 

 typical form. While Hydrogera has frequently been reported 

 from the United States, no mention of this species has come to 

 my notice. 



3. Stainiiaria aniericaiia Massee & Morgan. 



This species was first collected by Morgan at Preston, Hamil- 

 ton Co., Ohio, and later distributed by Kellerman from Hocking 

 Co. t During the present spring it was collected sparingly on 

 Equisetuin hyemalc at Lafayette.

A HITHERTO UNNOTICED RELATION BETWEEN ViOLA PEDATA 



AND Iris verna. — In April, 1906, among the pine|-clad moun- 

 tains of eastern Alabama, two of the most common and con- 

 spicuous herbs on dry sunny slopes were Viola pcdata L. and 

 Iris verna L. These species were in full bloom at Easter time 

 in Talladega, Clay, and Tallapoosa Counties, and often grew 

 within a few feet of each other, their habitats being identical.
