Peck : New Species of Fungi 67 



able, odor distinct, suggestive of the odors of the seashore ; lamel- 

 lae narrow, close, free, pinkish becoming purplish brown with age, 

 the edge white ; stem short, stout, firm, solid, equal, sometinies 

 bulbous, white, the annulus delicate, slight and easil}- obliterated ; 

 spores broadly elliptic, purplish brown, y-8 /x long,^ 5-6 // broad.' 



Pileus 5-20 cm. broad; stem 2.5-5 cm. long, 1.5-2.5 cm. 

 thick. 



Sandy soil near salt water, Lynn, Nahant and Marblehead, 

 Mass. June to December. R. F. Dearborn. 



This is a very interesting and an excellent mushroom. Dr. 

 Dearborn writes that he has used it on the table for fourteen years 

 and that it is the only mushroom that he has ever eaten in which 

 the stem is as good as the cap. He considers it the most hearty 

 and satisfying of all the numerous species that he has ever eaten. 

 Both its taste and odor is suggestive of the sea. The latter is 

 quite strong, and perceptible by one riding along the road by 

 whose side the mushrooms are growing. They sometimes ^row 

 m semicircles and attain a larger size in warm weather than in the 

 colder weather of autumn. They are most abundant in August. 

 The flesh when cut or broken quickly assumes a pink or reddish 

 hue on the freshly exposed surface. This is a very distinctive 

 character and with the maritime habitat makes the species easy to 

 recognize. Another species, Agaricns hacmprrhoidariiis Kalchb. 

 exhibits a similar change of color in its wounded flesh, but it is of 

 ^ very rare occurrence with us, does not, so far as ascertained, grow 

 near the sea, has a darker cap and a longer hollow stem. The 

 stem in the maritime mushroom is short and solid. Its collar is 

 very slight and easily destroyed.

Pileus fleshy, thick, convex, becoming nearly plane or cen- 

 trally depressed, glabrous, often wavy and split on the margin 

 white or whitish, often brownish in the center, flesh 1.5-2 cm! 

 thick in the center, thin on the margin, white, unchangeable ; 

 lamellae numerous, rather broad, close, free, ventricose, white be- 

 coming dark purplish brown with age, never pink ; stem firm, 

 stuffed with cottony pith, bulbous or thickened at the base, fibril- 

 lose, striate, minutely furfuraceous toward the base, annulate, pal- 

 lid or whitish, the annulus thin, persistent, white ; spores small 

 elliptic, 5-6/^ long, 3-4 /^ broad. 



^ Pileus 5-15 cm. broad; stem 10- 1 5 cm. long, about 2.5 cm. 

 thick.
