destructive to the heart and sapwood of both living and dead trees 
than is the case with the less common Fomes roseus. The decay 
caused by both species usually occurs locally at first in large indistinct 
pockets which later unite with other pockets. The wood within. the 
pockets breaks up into more or less distinct brown or dark brown 
rectangular blocks. The decay of T. subrosea is usually of a darker 
color and may become somewhat fibrous in some woods. 
Trametes subrosea may be confused with T. Feei Fr. (T. Sagree- 
ana (Mont.) Fr.), a common tropical plant originally described from 
Brazil. The latter has been found in southern Florida, where the 
former also occurs. The species are distinct on several counts, both 
as to pileus and spore characters and relation to substrata. "There 
is also slight difference in the character of their decays. 
The main distinguishing characters of the above three species 
may be summarized as follows: 
Context shades of pink or rose color. 
Context Japan rose to cacao brown or brownish vinaceous 
(Ridgway). 
Pileus usually thin but sometimes conspicuously stratified 
when old, normally zonate with radiating appressed 
fibrils when not obscured with new hyphal growth, 
brown, brownish pink, silvery gray or black with age; 
pores dark pink to dark rose, small, discolored with 
age; spores narrowly elongate, ellipsoid to cylindric or 
allantoid, hyaline, gutta not observed, average 6.3 X 
2-3 u; on wood of deciduous and coniferous trees in

Pileus thin, smooth, even, velvety, pinkish-brown to black 
when old; pores pink rose, or brownish vinaceous, 
black with age, minute, smaller than above; spores 
ellipsoid, rarely short cylindric, frequently acuminate 
at one end, average 6.4 X 3.14; on hard woods in the 
tropies, in the United States only in southern Florida. . Trametes Feei.. 
Context pale vinaceous pink (Ridgway) constantly of a lighter 
color than above. 
Pileus thick, distinctly stratified in split section when old, 
smooth, frequently conspicuously sulcate, pink, brown-

with a slight resinous crust when very old; pores light 
pink or light rose, somewhat brownish with age or when 
bruised; spores broadly elongate, ellipsoid to cylindric
