and the herbarium of the New England Botanical Club give the

C. APARINOIDES: naked portion of peduncle 0.3-3.5 cm. long; 
flowering calyx 1.3-3.8 mm. long, its lobes 0.7-2 mm. long; capsule 
1.2-2 mm. long. 
C. ULIGINOSA: naked peduncle 1-6 cm. long; flowering calyx (3—)4— 
6.7 mm. long, its lobes 2-4 mm. long; capsule 3.2-5 mm. long.

FOMES ROSEUS (A. & 8.) CKE. AND TRAMETES SUBROSEA 
NOM. NOVUM. 
JAMES R. WEIR. 
THE conflicting statements in the literature concerning the identity 
of Fomes roseus and the fungus commonly called “ Trametes carnea 
Nees" have led to confusion in the minds of students and investi- 
gators engaged in the practice of forestry and in the preservation of 
structural timbers. "This confusion is apparently due to a limited 
experience of the authors in studying the species in the field and super- 
ficial examination of the structure and appearance of the organism. 
For example, the insistence that “ T. carnea" is an annual plant (15), 
.that Fomes roseus may be distinguished by its ungulate form and 
stratified tubes (14), that the context color is the same in both species 
(15), and that one is a form or variety of the other are some of the 
statements published over and over again, none of which can be 
substantiated in fact. 
It is the purpose of this paper to point out some characters which 
definitely establish the entity of each of the species, to furnish a
