North American species being recognized, of which 13 are new 

 and many are newly combined. The genus Septobasidium treated 

 in the September number of the same volume contains 17 North 

 American species, of which 10 are new. 



Mushroom fairy rings of Tricholoma praemagnum found at 

 several places in Colorado by Francis Ramaley were described 

 and figured in Torreya for September, 1916, which number also 

 contains a redescription of the species by L. O. Overholts. This 

 large and interesting agaric was first described in North American 

 Flora from Saskatchewan, Canada. 



Entoloma cinchonense Murrill, described from Cinchona, 

 Jamaica, in Mycologia 3: 279. 191 1, has been, found to have 

 hyaline spores and is therefore here newly combined as Melano- 

 leuca cinchonensis Murrill. It is readily distinguished from 

 other tropical American species of this genus by its small, ochro- 

 leucous pileus and salmon-colored, notched lamellae. 



Professor George Massee, the well-known English mycologist, 

 died on February 17 at the age of sixty-seven. Professor Massee 

 was long connected with the Royal Botanic Garden at Kew and 

 published many books and papers on mycology. His private col- 

 lection of fungi and drawings was purchased by the New York 

 Botanical Garden some years ago. He has been one of the asso- 

 ciate editors of Mycologia since 191 1. 



Mr. San ford M. Zeller has made an extensive physiological 

 study of Lenzites saepiaria Fries with special reference to enzyme 

 activity. An interesting experiment by Mr. Zeller shows that L. 

 saepiaria will grow well on 50 per cent, resin by weight, which is 

 considerably more than is found in any coniferous wood, and that 

 growth of the fungus is not entirely inhibited by 85 per cent, 

 resin. 



Fine specimens of the common mushroom have been sent in by 

 Dr. S. M. Stocker, of Duluth, Minnesota, exhibiting abnormal 

 outgrowths of the fruiting surface on the top of the cap. The 

 inverted hymenium is in many cases not strictly lamellate but
