THE COURSE OF DEVELOPMENT IN ASCOMYCETES. 



Statement of facts. Species without gonidia ; others with a regularly 

 intercalated formation of gonidia. Different forms of gonidia in the 

 same species. Microgonidia and megalogonidia. Pycnidia, pycno- 

 spores, stylospores. Examples of species which have been fully 

 examined 223
