branches usually in groups of 3-6, all tending to curve in one direction, tips 

 more or less brown in color. KOH+, yellow, P+, reddish orange. 



On soil: San Juan Co.: Brown Island, 1940, 3208. King Co.: Chase 

 Bog, 1940, 3337. Snow Lake Trail, 3500 ft., 1931, 827. Pierce Co.: Silver 

 Springs, 2670 ft., 1931, 1118. Clallam Co.: Olympic Hot Springs, 1936, 

 A. H. Smith 2118 (F). 



The grayish color of this plant and the nodding tips of the branches help 

 to distinguish this species; also yellow color with KOH. 



4. Cladonia sylvatica (L.) Hoffm. Deutschl. Fl. 114. 1795. 

 Lichen rangijeriniis var. sylvaticus Linn. Sp. PI. 1153. 1753. 

 Cladonia rangiferinus b. sylvatica L. 



Podetia straw yellow (R), creamy white, sometimes with a grayish or 

 pale greenish tinge, surface distinctly arachnoid, but less strikingly so than 

 in CI. rangiferina, sometimes becoming weathered and verruculose, branch- 

 ing dichotomous or whorled, surrounding gaping axils, with frequent sub- 

 secund branches between the whorls on the main axes, thus making the 

 branching very dense, the tips of the ultimate branches usually in groups 

 of 3-8, inclined to be straight, sometimes brown, more often concolorous 

 with the rest of the podetia. KOH — , P-|-, reddish orange. 



On soil : San Juan Co. : San Juan Island, Friday Harbor, 1940, 3212, 

 Brown Island, 1940, 3209. Mason Co. : Mt. Elinor, 5500 ft., 1912, Foster 

 2113 (W). Grays Harbor Co.: Copahs, 1911, Foster 1428 (W). 



The yellow color, almost white when dry, helps to distinguish this 

 species from CI. rangiferina, also the negative reaction with KOH ; but no 

 doubt the two are often confused. 



5. Cladonia bacillaris (Ach.) Nyl. Not. Sallsk. F. et Fl. Fennica Forhandl. 

 8:179 (footnote). 1866. 



Baeomyces bacillaris Ach. (in parte) Meth. Lich. 329. 1803. 



Primary thallus rarely dying, grayish green or grayish olive (R), con- 

 sisting of squamules, lacinate lobed or margin crenate, flat or ascending, 

 scattered or crowded, under surface white. Podetia whitish, grayish green, 

 or grayish olive (R), cylindrical, slender, mostly decorticate and farinose 

 sorediate, sometimes corticate near the base and below the apothecia, bear- 

 ing a few squamules ; cupless or rarely with imperfect cups, simple or 

 sometimes branched near the apex, often sterile with obtuse or subulate 

 tips. Apothecia scarlet, solitary or clustered, 1.0-3.0 mm. across; disk 

 irregularly convex. KOH — , P — , no color changes with either. 



On rotten stumps or logs, rarely on soil : King Co. : Edgewood, 300 ft., 

 1940, 3079. San Juan Co. : San Juan Island, Friday Harbor, 1906, Fink

 Lichen bellidiflorus Ach. Lich. Suec. Prodro. 194. 1798.
