Physarum. 279 



From f mm. high. A very fine specimen named as above 

 was sent to me by Mr. H. Wingate, of Philadelphia. It appears 

 to differ from Physarum chrysotrichum only in the white nodes 

 of the capillitium and the very short stem. 



Physarum rufibasis, B. and Br. f K^< 



Scattered or gregarious, stipitate ; sporangia globose, dull 

 yellow or tawny, even, sprinkled with minute particles of lime, 

 dehiscing irregularly; stem elongated, slender, tapering upwards, 

 longitudinally furrowed, expanding at the base into a small, 

 circular hypothallus, bright brown, filled with minute granules of 

 lime; columella absent; capillitium dense, forming an irregular 

 network, nodes incrassated, irregularly angular, large, numerous, 

 filled with bright yellow granules of lime, connected at various 

 points by rather thin, long internodes ; spores pale lilac, globose, 

 very indistinctly verruculose, 10 \JL diameter.
