C. multiformis so far as is ascertainable seems to be an exclusively 
American form, unless two Scottish plants described by Stirton and alluded 
toby Wainio Mon. II, p. 454 may be related. The second of these C. arborea 
Stirt. Not. Brit. Clad. (1885) p. 4 according to the description, is not unlike 
certain states of C. multiformis , but Stirton remarks that the cups were all 
perforated. This seems to imply a relationship to C. crisp at a, and it is 
under this caption that Wainio records it. A specimen contained in the 
Tuckerman collection communicated by Sprengnel, marked “ex. herb. De- 
lise ’’clearly with the present, is labelled Cenomyce Novae Angliae Delise, 
but bn testimony of both Nylander and Wainio that name was also applied 
by Delise to C. crispata infundibulifera hence is untenable for the form here 
discussed. 
C. multiformis is found according to data accompaning specimens com- 
municated to the writer on dead wood, humus, thin earth over rocks and 
among mosses. In Knox Co., Maine, it is found in grassy tufts in old pas- 
tures and sparingly with densely growing C. gracilis elongata. It has 
been examined from Lake Nipigon, Ont. , Montmorency River, Que., The 
Gaspe Peninsular, Fraser Falls, Que., and the Klondike region, collected by 
Prof. J. Macoun. Chilson Lake, N. Y., Mrs. C. W. Harris; Lake Winnepe- 
saukee, N. H., Mrs. L. A. Carter; Sudbury, Mass., Miss C. M. Carr; Swan 
River Valley, Mont., Mr. T. A. Bonser; Pea Cove. Me., Mr. F. D. Merrill; 
Waltham, Mass., Mr. W. Gerritson; Guilford, N. H., Mrs. N. Smith, and 
Flag Island, Minn., Dr. B. Fink. The plant has been personally collected 
in various localities in Knox County, Maine, and in the White Mountains of 
New Hamshire. Rockland, Maine. 
ALECTORIA TORTUOSA SP. NOV. 
Thallus pendulous, elongated (30-40 cent.), lax, complicate, greenish-yel- 
low, greenish-olivaceous or greenish-fuscesce'nt ; the comparatively thickened 
major branches unevenly terete, terete-compressed or sometimes angulate 
the minor ones modified similarly and filiform ; rather remotely divided, the 
branching patent, axils compressed, webbed, and commonly somewhat 
lacunose, both major and minor branches more or less spirally elevated-white- 
striate; cortex smooth and sub-opaque. Apothecia not seen. 
Anatomically the plant agrees in all its details with that of other Alec- 
toria species. The characteristic cottony axis and filamentous cortical layer 
are identical with the similar elements of Alectoria sarmentosa Ach., which 
is indeed its nearest congener. The color of the thallus may be likened to 
that of the darker greenish states of Evernia vulpina , and in common with 
that species it communicates a little of its color to white blotters when wetted. 
The reaction is similar to that of Alectoria FremontiiTuok., A jubatapro- 
lixa Ach. and A jubata stricta Ach. being KHO-j-fuscescent Comparable 
with A. virens Tayl. in coloration, it differs in all other particulars. The 
peculiar twisted appearance of the cortical layer is found on splitting one of 
the branches to be structural, the torsion affecting all the layers. The extent 
of the twist is observed to equal six complete turns to the inch in one
