woods. This may belong to the same fungus, but one can not be 

 certain of it. 



84. Poria Calkinsii sp. nov. 



Effused for a few or several centimeters, becoming continuous, 

 1-2 mm. thick ; margin conspicuous, appressed, tomentose, isa- 

 belline in dried specimens ; context a distinct isabelline mem- 

 brane ; hymenium first appearing at the center of circular patches 

 of subiculum, becoming continuous, even, glistening, isabelline in 

 dried specimens ; tubes firm, angular, regular, 1-2 mm. long, 4 

 to a mm., edges at first rather thick and entire, becoming thin 

 and lacerate ; spores broadly ellipsoid, smooth, hyaline, rounded 

 at the ends,, uniguttulate, 4 X 2.5 /a. 



Type collected on fallen corticated hardwood branches in 

 Florida, W. W. Calkins 521. What appears to be the same spe- 

 cies was collected by Ellis on dead maple limbs at Newfield, New 

 Jersey, in October, 1874, 



85. Poria Parksii sp. nov. 



Entire plant pale-yellow when fresh, becoming distinctly fla- 

 vous on drying; effused for a few centimeters, continuous, sep- 

 arable, thin ; margin conspicuous, tomentose, more or less 

 membranous ; context like the margin ; hymenium becoming con- 

 tinuous, rather even, not glistening ; tubes short, small, thin- 

 walled, with entire to lacerate edges, the mouths circular at first, 

 becoming angular and longer than broad ; spores copious, smooth, 

 hyaline, subglobose, uniguttulate, 4 ft ; cystidia none. 



The type of this unusually attractive, bright-yellow species 

 was collected beneath leaves on roots of tan-bark oak in a dense 

 oak forest at the Boys' Outing Farm, Saratoga, California, Janu- 

 ary 13, 192 1, Harold E. Parks 965. Said by Mr. Parks to have 

 been collected at the same place in February, 1919, and. sent to the 

 University of California. Growing in this way under a heavy 

 deposit of leaves, the specimens I have seen may be abnormally 

 developed. 



86. Poria subradiculosa sp. nov. 



Effused for several centimeters, becoming continuous, insep- 

 arable, 2-4 mm. thick ; margin very broad and conspicuous in 

 young stages, thin, appressed, membranous, white to orange-
