BY WAY OF EXPLANATION. 



We are favored again with a short article by Superintendent 

 Hard and are able to reproduce one of his photographs illus- 

 trating the subject. 



We have to thank also Professor Atkinson, wliom we draw 

 upon again for some interesting statements as to the uses of 

 Mushrooms, which he has published in his excellent book. Mush- 

 rooms, Edible and Poisonous. 



Other Figures which we present are a neat little Marasinius, 

 which we do not want to eat, but do w^nt to look at (beauty is 

 its own excuse for being). Then the Myccna follows — another 

 charming little plant of the woods; the Plutcus ccn'iinis, which 

 we have once before illustrated, all ought to know (it has pinkish, 

 gills, the color deepening after the cap has expanded for a time — 

 ihev are white at first : the stem can be easily twisted out of a 

 socket-like cavity) — this medium-sized Mushroom being one 

 rmong the best edible species ; then the last page shows one of 

 the Puffb-^lls — Scleroderma as it is called rightl}-. because it has 

 a Jiard wall or covering. 



CoKUKCTioN. — A rcgrtttable mistake in regard to placing one 

 of the illustrations in the last number was made, and readers are 

 therefore requested kindly to change the name Pauceolus cam- 

 panulatus (Fig. 191) to Stro-pha'-ri-a seiii-i-<j!o-bo'-sa. The 

 correct half-tone of Pr.naccli^s campanula.tus will be given in a 

 future number.

The gills are adnate, scmetimes slijjhtly dtcurrert, sometimes slightly 

 notched, somewhat crowded, bread, white cr whitish. 



The stem is often eccentric, two to three inches long, one inch thick, 

 usually curved as in the figure, solid, firm, thickened at the base, smooth, 

 sometimes tomentose, ei^pecially at the base. The spores are nearly round, 

 the diameter being .00(2 in. 



This plant usually grows on elm logs yet 1 have found it on hickory
