Ohio Mycological Bullet m No. 4.. 



Mycological Exhibition. — Friday afternoon. May 22, from 2 to 

 5 o'clock, there will be an Exhibition of Mushrooms in the lecture room 

 of the Botanical Building. Ohio State University, to which the public is 

 cordially invited. A short lecture will be given to amateurs at 4 o'clock. 

 Members of the Ohio Mycological Club living at, or not too distant 

 from Columbus, are cordially invited to attend, but this notice is given 

 to all readers of this Bulletin as a suggestion, which perhaps in some 

 cases might be carried out by members in their own communities. If 

 one or two undertake an exhibition, at some stated time, of what might 

 be found in their region, cordial assistance doubtless would be given 

 by the teachers of the public schools, many pupils and other enthusiasts. 



If there is a local Horticultural Society. Farmers' Club, or Floricul- 

 tural Association, such an organization might lend assistance or even take 

 the initiative in such an exhibition. Increasing the interest in Mycology 

 and disseminating information leading to more extended study and wider 

 use of Mushrooms, would certainly be some of the valuable results of such 

 an undertaking. 



It would perhaps also be an opportune time to make the Bulletin 

 known to others, "price 10 cents," through the kind efforts of pres- 

 ent members. Moreover the request is made that as far as convenient 

 some specimens of Mushrooms be sent for the May 22d exhibition at 

 Columbus, for which the editor extends thanks in advance to any con- 

 tributing members. 



The Free-Cap Mo-rel'. — The Morel shown in fig. 19 is called Mor- 

 chel'-la sem-i-lib'er-a — the second, or specific name suggesting its dis- 

 tinguishing character, namely, that the loivcr portion of the cap is free 

 from the stem. 



In the common Morels, those forms called by botanists Mor-chel'-la 

 es-cu-len'-ta, Mor-chel'-la con'-i-ca and Mor-chel'-la de-li-ci-o'-sa, 

 (shown in figs. lU, 11 and 18), also Mor-chel'-la cras'-si-pes (which is 

 much like the foregoing, but the cap is equal in width to, or scarcely 

 broader than the granudar irregularly furrowed .stem — cras'-sus meaning 

 broad), the cap is ad'-nate, that is wholly attached to the stem, there- 

 fore not having a free margin below ; in other words the cap is bell- 

 shaped. 



A form from Michigan recently described by Prof. Peck, called Mor- 



I'ig. 20. I'e-/.i'-za re-tic-u-la'-ta. Reticulate Peziza. KdiV)le. Nearly the nat\iral size. 

 Same species as shown in Fig. 21.
