Brown, comm. Baker 1030, April 28, 1913, parasitic on living cicadas. 
We have seen only one cicada beset with the fungus. Our specimen is 
already much advanced in development, hence we have seen no trace of 
mycelium. The conidia seem to be formed in chains, but they readily segre- 
gate. Younger stages of this interesting fungus will be necessary to deter- 
mine if it is indeed an Oospora or not.
