tnelleiis, a jKuasiu- attackin'i; tirnbor and well known to foresters 

 as " honey fungus." This secutnl specii-s of tlie /v.'<xi^<-< in woitliy 

 of mention here ; in the first place because, as can be seen from 

 Fig. IJ3, it forms an excellent example of a pleomorphous 

 fungus; chiellv, however, because the ascospores are siniilar in 

 shape to those of Sai-charomi/cea aiioinaiu-if (to be described later 

 on) and its congeners. 

 It was on the basis of 

 this similarity that, some 

 years ago, and again 

 more recently, more 

 than one njvcologist was 

 led Ui discuss the pos- 

 sibility of the ^'(j/vAa- 

 ruiiii/f't'fiK having origin- 

 ated (j^ 244) from this 

 .species or one nearly 

 allie<l thereto. How- 

 ever, no one has yet suc- 

 ceeded in arriving at 

 anything beyond mere 

 hypotheses in this con- 

 nection J and moreover, 

 similarly sluipeil spores 

 are also found in other 

 low Asrfnni/'-t'ten, e.g. AsruiiJea niheitrenii. These few remarks are 

 all that it is nece.ssjirv to make, from our point of view, with
