OHIO BIOLOGICAL SURVEY 
EXPLANATION OF PLATE IV. 
Note: Where no magnifications are given an enlargement of 79 diameters for perithecia, and 450 diame¬ 
ters for hairs, paraphyses, asci, and spores is to be understood. The illustrations were drawn from a 
magnification double that given here and reduced one-half in the process of reproduction. 
1-6. Fimetaria Jimicola. 1. Perithecium shown as cut on one side showing spores 
within, mycelium, and the attachment to the substratum. Shaded portion 
filled with asci. 2. Tip of an ascus showing pore at tip, and hyaline envelope 
as seen in the ascus, and germ-pore pointed downwards. 3. Young spore, 
showing hyaline envelope, germ-pore, and three oil globules. 4. Mature 
spores. 5. Spore end view. 6. Spore seen obliquely. 
7-8. Fimetaria pilosa. 7. Perithecium. 8. Ascus showing spore-arrangement. 
9-16. Fimetaria discospora. 9 & 11. Perithecia in outline. 10. Perithecium. 12. 
An acicula. 13. Paraphyses and asci in outline. 14. Mature ascus. 15. A 
spore. 16. Rather large spores seen in one specimen. Thought by some 
authors to belong to a different species. Seems to be a variation in the same 
species.
