 seen from our photograph, are not truly hexagonal, but tend to daedaloid. 

 Daedalea quercina is presumed not to occur in the tropics. If it does, this plant 



must be referred to it. It is

This is known from a single

 from Brazil. No similar speci-

 impression that it is an aberrant,

32 I think it was a Mr. Smith who some years ago distributed some specimens from Cen- 

 tral America "determined" by Ellis. Among others was a specimen labeled "Irpex maximus." 

 It has no resemblance whatever to "Iipex maximus," which is only an irpicoid condition of 

 the common Polystictus occidentalis of the tropics. Ellis', of course, had no way of knowing 

 that, and his determinations of tropical species were but little more than a vague guess. The 

 plant that he called "Irpex maximus" I have always considered as a tropical, irpicoid form of 

 Daedalea quercina, the same as I consider Hexagona aequalis to be a tropical, hexagonoid form 

 of the same species.
