298 THE BASIDIOMYCETES 



are 2-celled, and each cell contains 2 nuclei, 1 of which enters the 

 basidiospore and the other degenerates. 



In HoeJmeliomyces delectans [Moller (1895)], occurring in 

 Brazil on fallen leaves, the interlacing hyphae of the cup-shaped 

 head overarch the developing basidia, so that the fructification is 

 at least partially angiocarpous. The transversely septate basidia 

 are 4-celled and form 4 basidiospores, which are capable of germi- 

 nating bv repetition. 



In the highest member of the series, Phleogena (Pilacre) fagijiea, 

 occurring on beech logs, the fructifications are entirely angio- 

 carpous [Shear and Dodge (1925)]. The 4-celled transversely 

 septate basidia are borne within a peridium-like tangle of interlac- 

 ing hyphae. Phleogena also produces conidia of the Rhinotrich- 

 um type. In spite of the heterobasidiomvcetous nature of the 

 basidium in Phleogena, Shear and Dodge are inclined to regard 

 this genus as a Gastromycete because of its angiocarpous devel- 

 opment.
