Hygrophorus laurae decipiens Pk. 



DECEIVING HYGROPHORUS 

 PLATE 88, FIG. 8-1 1 



Pileus thin except in the center, broadly conic with involute 

 margin when young, becoming convex or nearly plane, glutinose, 

 white with a dingy yellow or smoky brown spot in the center, flesh 

 white, taste mild; lamellae subdistant, adnate or decurrent, white; 

 stem rather long, slender, viscid when moist, solid, attenuate at the 

 base, white with white particles at the top; spores .00028-.0003 of 

 an inch long, .00016-. 0002 broad. 



The deceiving hygrophorus is most closely related to the laura 

 hygrophorus, from which it can scarcely be separated in the fresh 

 or living condition. The thinner flesh of the cap, the more slender 

 stem more constantly narrowed and pointed at the base and its 

 tufted mode of growth are the principal marks of distinction in the 

 fresh plant. It is likely to be taken for a slender tufted form of the 

 laura hygrophorus and the persistency of its colors in drying is the 

 chief reason for considering it a variety of the species instead of a 

 mere form. The cap is 1.5-3 inches broad; the stem 1.5-2 inches 

 long, 3-5 lines thick. It grows in tufts among fallen leaves in woods 

 or their borders, and may be found in September. Its edible charac- 

 ter is similar to that of the laura hygrophorus. 



Boletus laricinus Berk. 

 LARCH BOLETUS 

 PLATE 89, FIG. 1-7 



Pileus fleshy, broadly convex or nearly plane, viscid when moist, 

 sometimes squamose, dingy white or grayish white, flesh white; 

 tubes short, adnate or slightly decurrent, whitish when young 

 becoming darker and brown with age, their mouths large, angular, 

 subcompound; stem short, solid, annulate, reticulate above the 

 ring, grayish or brownish below; spores brown, oblong .0004-. 0005 

 of an inch long, .00016-. 0002 broad. 



The larch boletus takes its name froni its place of growth. It 

 always grows under or near larchtrees. It is closely related to the 

 Elba boletus, B. elbensis Pk., which is found under or near 

 tamarack trees in the northern part of our State. In the larch 

 boletus the cap is paler and has no pinkish brown tint which often 

 is seen on the cap of the Elba boletus. Its cap is sometimes adorned 

 by brown or blackish scales which are easily rubbed or washed 

 away, leaving the whitish cap entirely naked. The flesh is soft and 

 white or whitish. The tubes are at first whitish but they change
