Not Mucor pyriformis Leers, Fl. Herborn. 288. 1789. 



It is unfortunate that Fischer's name had been used before and 

 therefore must be reduced to synonymy. The pear-shaped colu- 

 mella suggested the name given by Fischer. 



The specimens referred to this species have a smaller columella 

 and larger spores than those given in the original description (see 

 Torreya 9 : 143. 1909). 



Substrata : On dung of deer. 



Specimens examined: Pennsylvania, Sumstine. 



Illustrations : Fischer, /. c. f. jo c. 



3. Hydrophora Taeniae (Fairman). 



Mucor Taemae Fairman, Proc. Rocli. Acad. Sci. 533. 1891. 



The author of this interesting species gives the following 

 description, " Sporangiferous hyphae erect, rarely if ever branched 

 septate, yellow, 7/x diam. 



Sporangia globose, brownish or yellow brown, smooth, mostly 

 40/X in diam. Columella elliptical or sub-sphaeroidal, at times 

 with contraction at the base, brownish. 



" Spores globose, or ellipsoid, light yellow, 3-5)U, in diam. with 

 smooth epispore. Zygospores not observed." 



Substrata: On segments or joints of tape worm {Taenia 

 solium). 



Specimens examined: New York, Fairman. 

 Illustrations : Fairman, /. c. pi. 4, f. 4-6. 



4. Hydrophora rufescens (Fischer). 

 Mucor rufescens Fischer, /. c. 192. 1892. 



Mucor rubens Vuillemins, Bull. Soc. Myc. Fr. 3: iii. 1887. 



Vuillemin's description is incomplete but in all probability he 

 had the same plant before him as Fischer. The latter author 

 cites Mucor rubens as a synonym of his species. 



The sporangiophores are very flaccid and form a network 

 over the substratum. 



Substrata : On elephant dung. 



Specimens examined: New York, Sumstine.
