Ill _ THE FOREST FLORA 



The more heavily forested areas present the characteristics of 

 the wooded sections of the eastern part of the state, with this 

 difference that fewer species appear here, these groves presenting 

 in fact an attenuation of the southeasterly forest flora. 



The more open woods and the borders of the groves have al- 

 ready received attention. The deeper woods offer little that is 

 unique. The dominant flora is of the usual type, and chlorophyl- 

 less Thallophytes, such as slimemoulds, fungi, and with them 

 the lichens, appear in larger numbers. The mycological flora is 

 best developed in the woods at Elm Crest, near the Inn, and at 

 Center lake, and also in the deep woods of the ' ' big loop ' ' of the 

 Little Sioux river. 



A brief report on the flora of the forested areas follows : 



Subkingdom I. — THALLOPHYTA 



Fungi. — Mr. L. A. Giddings prepared a list of the fungi and slime- 

 moulds, collected largely by himself, for this paper. The list consists largely 

 of forest forms, and is here presented as originally prepared, but without 

 the prairie, swamp, and introduced species, which were transferred to their 

 respective lists, and with the addition of several species from the collections 

 of President Macbride and the writer. The latter are marked with an 

 asterisk. Most of the identifications in the entire list were verified by Presi- 

 dent Macbride.
