REVISION OF ENDOGONEAE. 319 



Endogone pulvinata Henn. 



(Figs. 41-43.) 



Hennings (1897), p. 212: nee Lloyd (1918), p. 800, fig. 1240. 



Dr. Lindau has very kindly allowed me to see a fragment of the 

 type of this species, collected by GoUmer, and found growing on the 

 ground at Caracas, Venezuela. The specimen, which is not in the 

 best condition, resembles E. fulva in general appearance and color. 

 The spores, however, although they have thin walls like E. fulva and 

 are similarly separated from the hypha by a septum, are distinctly 

 different in general appearance, being more nearly spherical, often 

 asymmetrical, and seldom showing the considerable difference between 

 the two diameters that is so characteristic in the last mentioned 

 species. The larger spores are 85 X 85 /z or 75 X 85 /x, according as 

 the axes tend to vary slightly : the average being about 75 X 75 // or 

 75 X 70 fjL, with considerable variation below these dimensions, and 

 no little variation in outline. The walls are 2-4 /x thick, as in E. fulva, 

 and the hyphae which, in the specimen seen, are for the most part 

 disorganized, appear to be entirely similar and loosely woven.

Patouillard first called attention to the fact that Paurocotylis fulva 

 belonged to the genus Endogone and that it was unrelated to P. pila 

 Berk, which is the type of the genus. From the data and figures 

 given by Bucholtz, who has examined the original material in both 

 instances, the identity which he suggests between E. fulva and E. 

 lignicola seems almost certain. The fact that they occur in widely 

 separated regions, the one in Ceylon, the other in the West Indies, is 

 shown to be of little significance; since other species, like E. malleola 

 may have, as will be seen, an equally wide distribution.
