MURRILL : POLYPORACEAE OF NORTH AMERICA 91 



River, Australia. There is ample excuse for this, however, in the 

 fact that this species is described in a work on Cuban fungi and is 

 undoubtedly considered by the author to exist in Cuba ; never- 

 theless, since no definite statement to this effect nor the citation of 

 a collector's number accompanies the description, the type locality 

 as given and also as implied in the personal specific name must be 

 considered the correct one for the species. There exists a very 

 close relationship between the various forms of D. ambigua and 

 species described from regions of the Orient, but a discussion of 

 this relationship is beyond the scope of the present article. 



As one may judge from the above discussion, Agaricus Aesculi 

 is a variable species and liable to confuse the collector who relies 

 too much upon regularity of pore-structure. If one considers the 

 variability of the genus, however, he will have little trouble in 

 distinguishing it by color, surface and size. It is found on stumps, 

 trunks, and other forms of decaying wood of oak, sycamore, etc., 

 in the Southern states. Specimens are at hand from Missouri, 

 Demetrio ; Kansas, Bartholomew; Ohio, Morgan, Lloyd; South 

 Carolina, Ravenel ; Florida, Martin, Ran, Calkins, Lloyd ; Texas, 

 Hodson 320.

The name Daedalea elegans was first assigned to plants found 

 on tree trunks in Guadeloupe. Sprengel's original description is 

 as follows : 



" D. coriaceo-lignosa sessilis, pileo supra albido glabernmo, 

 subtus alutaceo, lamellis anastomosantibus in poros marginales 

 abeuntibus." 



This was enlarged by Fries after the study of a considerable 

 variety of forms. Ten years later Fries himself described another 

 form of the same species collected by Beyrich in Brazil under the 

 name of Daedalea deplanata. His Trametes centralis, also a syno-
