,74 Forty-first Annual Report on the 



Cortinarius rigidus, Fr. 



Catskill mountains. September. 



Hygrophorus Laurae, Morg. 

 Woods. CatsMll mountains. September. 



The squamules at the top of the stem are sometimes reddish. The 

 disc is sometimes yellowish. 



Lactarius aspideus, Fr. 



Borders of woods. Catskill mountains. September. 



A pretty but rare species, easily known by its pale yellow or straw 

 color and the lilac hue assumed by wounds of the lamella; or flesh. 

 In Systema Mycologicum the stem is described as hollow and spotted. 

 In our sj)ecimens the stem is hollow but not spotted. It is colored 

 like the pileus and the spores are broadly elliptical or subglobose* 

 slightly rough, .0003 to .0004 in. long. 



Lactarius maculatus, n. sp. 



Pileus fleshy, firm, at first convex and umbilicate or centrally 

 depressed, then subinfuudibuliform, glabrous, viscid when moist, 

 concentrically spotted, especially toward the margin, varying in color 

 from grayish-buff to grayish-lilac, flesh subconcolorous, taste acrid 

 and unpleasant; lamella) close, thin, sometimes forked, adnate to 

 decurrent, pallid or cream color; stem short, equal or tapering toward 

 the base, hollow, spotted, coloredlike, or a little paler than, the pileus; 

 milk at first whitish with a cream-colored tint, wounds of the flesh and 

 lamella) changing to lilac; spores sub globose, echinulate, .0004 to .0005 

 in. long. 



Pileus 3 to 5 in. broad; stem 1 to 2 in. long, 5 to 8 lines thick. 



Thin woods and pastiires. Catskill mountains and Menands. 

 August and September. 



This sj)ecies is allied to L. uviduH, with which it was united in the 

 Thirty-eighth Report as variety magnus. Having had the opportunity 

 of investigating it in the fresh state, it seems to me to be a distinct 

 species, readily recognized by its larger size and its firmer, spotted 

 pileus which is centrally depressed or infundibuliform. I have not 

 seen it at all umbonate. The spots of the pileus are arranged in con- 

 centric circles and by their confluence the pileus often appears to be 

 zonate. The change of color assumed hj wounds is similar to that 

 which takes place in L. iividus.
