Philippine Basidiomycetes—IV 
PauL W. GRAFF 
The following pages are presented in continuation of papers 
already published* on the basidiomycetous flora of the Philippine 
Archipelago. The fungous flora of -the tropics is proving to be 
much more extensive than had previously been imagined, and the 
range of many species found to be much wider than formerly sup- 
posed. In a few instances species already reported from the 
Islands have been included for the sake of correction in name, ex- 
tension of synonymy, and distribution. The value of range- 
notes is becoming more and more evident when the extension 
rather than the diminishing area of habitats is noticed. No new 
species will be found described in this paper, a fact which will 
doubtless be interpreted by some as a loss of golden opportunity. 
The identification of species already described and but imperfectly 
known seems to the writer more important than searching for 
minor differences as an excuse for creating new plant names and 
more confusion.
