Mycologia 



The Boletaceae of North America will be published in mono- 

 graph form at the close of the year. Specimens of these plants 

 are desired from as many stations as possible. Species may be 

 determined more or less accurately in the fresh condition by the 

 use of the keys published in this number and in No. I of Myco- 

 logia. All specimens should be thoroughly dried by artificial 

 heat, using a piece of wire netting suspended over a lamp or 

 stove, or some other contrivance, and afterwards packed in boxes 

 with naphthalene or moth balls. 



The present season was somewhat earlier than usual for the 

 larger fleshy fungi. Coprinus micaceus appeared April 15, and 

 has been abundant since that time, after rains. A few plants of 

 Coprinus comatus appeared about May 15 on a lawn where they 

 grew late last fall, but these were probably exceptional, having 

 passed the mild winter in the button stage. Pleurotus sapidus 

 was fully grown and abundant on May 1. Pluteus cervinus 

 occurred in great quantity on an old sawdust pile on May 15. 

 Before the end of May Clitocybe multiceps appeared on a lawn 

 where it grew last autumn, and has been abundant since. Poly- 

 porus caudicinus always matures early, so it was not surprising to 

 find it in May ; and the same is true of Morchella. A number of 

 small fleshy forms appeared in fields and on roadsides during 

 May and early June, but this is not unusual. A few plants of 

 Coprinus atramentarius and Hypholoma appendiculatum, how- 

 ever, came as a surprise about May 15. On June 4, eighteen 

 specimens of Agaricus campestris were collected in a field not far 

 from Bronx Park. 



" The Association internationale des Botanistes founded, some 

 years ago, an office where pure cultures of fungi can be obtained, 

 either in exchange or on payment. The above-mentioned office 

 proposes to compose a living register of the described fungi. 

 Large numbers of species are mentioned in the handbooks which 

 are said to be insufficiently described and which cannot possibly
