 Editors Note. — Grateful acknowledgement is again made for me.. . -»j 

 hearty co-operation in extending the membership of the the Ohio M'ii^d'^*'^^^ 

 LOGICAL Club; for the interest manifested in the Bulletin; the corres- 

 pondence already elicited in connection with fungi, interesting, edible or 

 otherwise; and the specimens sent for illustration of observations made, 

 or for inspection. Some of the correspondence and interesting notes 

 will appear from time to time in the Bulletin. This is a phase of the work 

 not particularly mentioned hertofore, yet it is boped that it will prove very 

 interesting and profitable. 



I desire to say that receipt of Bulletins, subsequent to No. 1, indicates 

 that you or some friend has paid the fee of 10 cents. The Bulletins will 

 be mailed to no one unless this amount has been paid. From time 

 to time the additions to the membership roll will be printed. Very fre- 

 quently it will be several days, may be five to ten, before Bulletins 

 can conveniently be sent after the request has been received. It is hoped 

 that the number of mistakes on our part will be reduced to a minimum ; 

 please remind us at once if delinquency occurs. 



Some Study Necess.vkv. — One can not positively know the kinds of 

 mushrooms without some close scrutiny or careful study. There are so 

 many kinds, and often they differ so little from each other, that thorough 

 acquaintance is indispensable to a correct judgment in regard to them. 

 No friend or instructor can enumerate the points for you, so that off-hand 

 you may then certainly know the mushrooms and safely separate the good 

 from the bad. But by carefully noting all the characters of any species that 

 you may find — color, texture, size, shape, and other points of its structure, 

 where it grows, any peculiarities in its mode of development ; then study- 

 ing another kind in the same manner ; you will during the season learn 

 really to know quite a number of species. If this plan is continued from 

 year to year you ought to become acquainted with all the conspicuous kinds 

 that occur in your neighborhood, and know them better than many 

 botanists do. If an attempt is made to record observations and make 

 sketches (perhaps using water colors), much more pleasure and profit will 

 lie realized. Some hints or directions will be given in the next Bulletin.

Cap, or pi'-le-us — Tbis is the 

 upper portion, more or less ex- 

 panded, usually regular in shape. 

 i)Ut sometimes various ; its pur- 

 pose is to bear the spores, or mi- 

 croscopic bodies for reproducing 

 the species, comparable therefore 

 in function to seeds of our com- 

 mon plants. 



Gills, or la-inel'-lae. — These are 

 the thin plates on the under side 

 of the cap, differing in shape, 

 mode of attachment, color and 

 consistenc}' in different species. 

 In the Pore Fungi and in the 

 Spine Fungi they are replaced by 

 pores and soft spines respectively. 

 On the surface of the gills, the 

 tubes, and the spines the spores 

 are produced.
