Summary
1. | There is great variation in the sporangiocarps of E. malleola. Large and small sporangial types of fructifications are noted. | ||||
2. | The spores germinate readily in water. | ||||
3. | By means of anastomoses larger distributive hyphae develop. | ||||
4. | Protoplasmic movement is very rapid in the distributive hyphae. | ||||
5. | Large masses of firmly interwoven moniliform cells superficially resembling sporangiocarps develop on cultures, but true sporangiocarps were never produced. | ||||
6. | The development of the sporangia is entirely phycomycetous. | ||||
7. | A close relationship between E. malleola and Mortierella is noted. |
I wish to express my indebtedness to Dr. Roland Thaxter for suggestions during the progress of my work and for reading a first draft of this paper and adding more helpful suggestions. Thanks are also due Dr. Thaxter and Dr. E. A. Burt for identifications and Prof. T. J. Fitzpatrick for proof-reading the paper.
