Murrill: Dark-Spored Agarics 



63 



Illustration : Mycologia 7 : pi. 158, f. 7. 



This species is very abundant in the northeastern United States, 

 varying considerably in size and habit, but easily distinguished 

 from D. appendiculata by its darker color and smaller spores, 

 which are very blunt at both ends. When I described and figured 

 it in Mycologia in 191 5 as H. Candolleanum, I had not examined 

 authentic European material, which shows at once much larger 

 spores. H. subaquilum is represented at Albany by a dozen or 

 more plants from Piseco and Lake Pleasant, New York, displayed 

 on two herbarium sheets. Peck states that the spores are 4-5 /x 

 long, which is correct. H. madeodiscum is represented by only 

 three plants, which do not appear different from the specimens of 

 H. subaquilum, and the spores measure 4-5 x 3 fx, although Peck 

 describes them as 8-10 x 5-6 ^. A specimen at Albany deter- 

 mined as H. madeodiscum by Burt, who collected it in Vermont, 

 has been changed by Peck to H. appendiculatum, 



2. Drosophila pecosense 1 (Cockerell) comb. nov. 



Hypholoma pecosense Cockerell, Jour. Myc. 10: 108. 1904. 



Pileus 2.5 to nearly 4 cm. in diameter, slightly convex, sometimes 

 slightly umbonate, margin nearly even, bearing remains of a veil 

 as light-yellow, irregular scales; surface smooth, slightly inclined 

 to be viscid, not at all striate, scaly or silky, creamy-white, more 

 ochraceous on the disk, but always pallid ; context not changing 

 color on bruising or breaking, taste mild, not bitter ; lamellae pale- 

 purplish-gray, inclined to be white at the junction of the stipe, 

 minutely white-furfuraceous on the edges; spores pale-purplish- 

 brown under the microscope, broadly ellipsoid to slightly ovoid, 

 9-12 x 5-8 /x; stipe yellowish-white or very pale ochraceous, slightly 

 striate from the very narrowly decurrent lamellae, white-furfura- 

 ceous, otherwise smooth and shining, hollow near the apex, 5.5 to 

 nearly 9 cm. long. 



Type locality : Pecos, New Mexico. 

 Habitat: Unknown. 

 Distribution : Unknown. 



1 Since the above was put into type I have located the original specimens 

 sent by Cockerell to Earle and they prove to be a species of Stropharia. See 

 my next article.
