3. Gomphidius nigricans Peck, Ann. Rep. N. Y. State Mus. 48: 



no. 1897 



Pileus convex or nearly plane, 2.5-5 cm - broad; surface pale- 

 brownish-red, covered with a tough gluten which becomes black in 

 drying ; context firm, whitish ; lamellae distant, decurrent, some of 

 them forked, white, becoming smoky-brown, black in the dried 

 plant; spores oblong-fusoid, 15-25 x 6-7.5 stipe subequal, longer 

 than the diameter of the pileus, glutinous, solid, at first whitish, 

 especially at the top, soon blackish by the drying of the gluten, 

 whitish within, slightly tinged with red toward the base, 3.5-6 cm. 

 long, 4-8 mm. thick. 



Type locality: Westport, New York. 

 Habitat : Under pine trees. 



Distribution : New England to Tennessee ; also in Europe. 



Illustration : Atk. Stud. Am. Fungi /. 50, 51. 



Good specimens are at Albany, attached to a herbarium sheet. 

 According to Peck, the entire plant is black when dry because of 

 a blackening gluten which covers it. 



4. Gomphidius vinicolor Peck, Ann. Rep. N. Y. State Mus. 51 : 



291. 1898 



Pileus thick, fleshy, convex or nearly plane, 2,5-6 cm. broad; 

 surface viscid, dark-red, becoming blackish on drying; lamellae 

 distant, decurrent, olive-brown or blackish when mature; spores 

 oblong-fusiform, smooth, smoky-brown to black, 12-14 x 3.5-4^; 

 stipe subequal, glabrous, solid, vinous-red, paler within, 3-6 cm. 

 long, 4-8 mm. thick. 



Type locality : Lake Mohonk, New York. 



Habitat : On the ground in coniferous or mixed woods. 



Distribution : Eastern United States, New York to Alabama ; 

 also in California. 



Good type specimens are to be seen on a sheet at Albany. The 

 California plants are larger and have spores measuring about 

 17.5 x 5 p.. KaufTman refers a small Michigan plant to this species 

 as a variety and says that it may be necessary to separate it 

 specifically because of its smaller size and smaller spores.
