showed him the photographs, told him the names of each and the 

 parts of the mushroom. The subject was not mentioned again 

 until a week later when I brought in a few specimens of one of 

 the species. "What is the name of this?" I said. "That's 

 the shaggy-mane," he said. "What partis this?" "That's 

 the cap." "And this?" That's the ring." "And this?" 

 That's the stem." " Now, father," he said, " where's the ink- 

 cap? " At another time he was able to select the ink -cap from 

 among a miscellaneous collection. 



While the Coprinas micacetis usually grows on decaying wood, 

 or roots, etc., underneath the soil, the shaggy-mane and ink-cap 

 grow in rich soil in grassy places, especially such as have been 

 quite recently manured. This latter peculiarity of growing on 

 manured ground, or on dung, so characteristic of a number of 

 the species of the genus, suggested the name '' coprinus,'' from 

 the work " ^^/>r(75, " meaning dung. 



A large number of the species of the genus, practically all the 

 large fleshy ones (some of the smaller also) diliquesce into an 

 inky fluid. In the delicate or membranous ones, usually quite 

 small species, the pileus splits in radiating lines above each gill 

 in such a way that the gill itself is split downward, thus giving 

 to the pileus a fluted appearance. 



In bulletin 138 the writer suggested the formation of mycolog- 

 ical clubs as a medium for the exchange of information among 

 interested persons in a given community. At that time there 

 was already in existence among others, the Boston, Mycological 

 Club, New York Mycological Club and the Philadelphia Mycolog- 

 ical Center. Since that time there have been organized the 

 Washington Mycological Club, Chicago Mycological Club, and 

 others. 



Cornell Mycological Club. 



A mycological club has recently been organized at Cornell Uni- 

 versity, with a somewhat broader work in view. It is called the 

 " Cornell Mycological Club " and is under the supervision of the 

 members in the Botanical Department. Its purpose is to study 

 the fungi, to propagate information concerning them among its 

 members, and to encourage the growing popular interest in those
