label but has been crossed out. There is nothing on the sub- 

 stratum to indicate the presence of a Mucor. 



3. Mucor tenuis. The packet contains small pieces of dis- 

 colored wood. 



4. Mucor alho-virens. No specimen in the packet. 



5. Mucor caninus. No specimen in the packet but inside the 

 packet is written "Mucor stercoreus, Beth., Aspergillus flavus, 

 Salem." 



6. Mucor Fimbria. Packet empty. 



7. Mucor ascophorus. No specimen in the packet but an 

 additional label reads, Ascophora Mucedo." 



8. Mucor truncorum. Only a few stems (sporangiophores ?) 

 were found. Impossible to identify. 



9. Mucor capitato-ramosus. This was a new species. A rem- 

 nant of the host, possibly a Polyporus, was the only thing found 

 in the packet. ' See under Syzygites aspergillus. 



10. Mucor echinophila. This is also described as a new spe- 

 cies. The specimens are all gone and the identity is uncertain. 

 The description is brief and inadequate. See Schweinitz, /. c. 

 No. 2'/'42. 



11. Syzygites megalocarpus. The packet is empty, but in all 

 probability he had Syzygites aspergillus. 



12. Phycomyces nit ens. A few sporangiophores clearly indi- 

 cate this species. 



13. Thamnidium elegans. Not this species, whatever it is. 

 The material is too scanty for identification. 



14. Pilobolus crystallinus. The packet contains some dried 

 manure but there is no evidence of this species. 



The Berkeley and Curtis Species 

 In Grevillea 3 : 148-149, the following new species are 

 described from America by Berkeley and Curtis : 



I. Mucor paradoxus. This plant was collected by Michener in 

 Pennsylvania on decaying Boletus. " The Flocci are short, 

 hyaline, the vescicles (sporangia) of two kinds, the larger glo- 

 bose on longer flocci, the smaller obovate but narrow on short 

 pedicels springing from the mycelium." 



In Sacc. Syll. Fung. 7: 211, this is placed under the genus
