Exidia purpureo-cinerea (Fig. 736 enlarged surface showing the papillae). 



EXIDIA PURPUREO-CINEREA, FROM MISS A. V. 

 DUTHIE, SOUTH AFRICA. (Fig. 735.) We determine this from 

 the description and the fact that it was named from South Africa. 

 The short diagnosis does not tell much, but it is probably correct. 

 The type is at Berlin, but I am not able to tell much about it. We 

 noted at once that it was not a European species, differing in its mode 

 of growth, its paler color and the dense, minute papillae from Exidia 

 glandulosa, its nearest relative in Europe. It is a true Exidia with 

 globose, cruciate, pale colored basidia, 10 mic. in diameter, and 

 typical papillae. The spores are also typical of the genus, 6 x 10 

 reniform, subhyaline, with granular contents. To our eye, there is 

 nothing purple about it. The types at Berlin are very poor, and we 

 think these are the only good specimens in any museum.
