On Polytrichum and other mosses. New England and New 
York. August and September. 
The fructifications are very variable in form and they are 
attached in various ways to the moss plants; they may be some- 
what incrusting but at some distance above the ground. Тһе 
substance of the pileus is very soft and its upper surface is some- 
what bibulous and shows its interwoven fibers under a lens. 
The spores of this species are given in Saccardo’s ‘Sylloge’ as 
8-10 x 5 y, but the European specimens of exsiccati cited below 
have small spores of the dimensions which I give for American 
specimens, and Bresadola, Ann. Муе. 1: 111. 1903, gives the 
spore dimensions as 3-4 x 3 и. Тһе specimens of C. Родопай 
were described as sterile by Peck; I find them to be rather im- 
mature but bearing spores 3 x 2 y. 
Specimens examined: 
Exsiccati: Karsten, Fung. Fenn., 441; Krieger, Fung. Sax., 1564. 
Finland: Karsten (in Herb. Fries), and Fung. Fenn., 441. 
Germany: Saxony, W. Krieger, Krieger, Fung. Sax., 1564. 
Vermont: near Falls of Lana, Salisbury, E. A. Burt. 
Connecticut: South Windsor, C. C. Hanmer, 1956, the type 
collection of Craterellus Pogonati Pk. 
New York: Floodwood, E. A. Burt. 
5. C. arachnoidea Peck, Rep. N. Y. State Mus. 44: 184 
(22). 1891. 
Type: in Collection New York State. 
Fructifications membranaceous, very thin, tender, white, 
externally downy, irregularly cup-shaped; hymenium some- 
what uneven in large specimens; spores colorless, even, some- 
what flattened on one side, 4-5 x 31-4 y, borne at least two toa 
basidium. 
Fructifications 2-4 mm. in diameter. 
On bark and mosses. Vermont and New York. September. 
Тһе cups are seated upon or developing from fine, white, 
loosely branching, webby strings of mycelium. This is a marked 
character in the type and is the chief character for separating 
this species from C. muscigena. The spores are slightly more 
globose than in the latter and it may be that the hymenium of 
C. arachnoidea is superior; in C. muscigena it is inferior. The 
hyphe are about 2 шіп diameter in each species.
