Sumstine: North American Mucorales 153 



Thamnidium by Berlese and De Toni. From the description, it 

 is impossible to tell where it belongs. 



2. Mucor Cucurbitarum. This was collected in South Carolina 

 by Ravenel and in New England by Sprague, on decaying gourds 

 and melons. The habitat and the description point to the com- 

 mon Mucor Mucedo. 



3. Mucor Beaumontii. Beaumont collected this species in Ala- 

 bama on decaying cabbage leaves. The spores are said to be 

 dark purple, otherwise it may be referred to Mucor Mucedo. 



4. Mucor curtus. This was found on decaying muskmelon in 

 South Carolina. The spores are " fusiform with a minute 

 appendage at either end, binucleate, .00057 about f as 

 much wide." This is surely not a Mucor. 



5. Ascophora fusca. This species was described in the Jour- 

 nal of the Linnaean Society 10: 363. 1868. It was collected in 

 Cuba on fruit of Atrocarpus. The sporangia are described as 

 " glohosis dein collapsis umhraculiformihus." The collapsed, um- 

 brella-shaped columella indicates Mucor Mucedo, or some species 

 of this genus.
