Among fungi collected recently in China by Mr. Frank N. 

 Meyer are specimens of Cryptoporus volvatus found on a dead 

 trunk of Pinus sinensis at Ching lung shan, Chili Province. This 

 interesting species has previously been collected in Japan. 



Five new species of Ravenelia from Texas, Arizona, and 

 Florida were recently published by W. H. Long in the Botanical 

 Gazette. These species are as follows : Ravenelia annulata, R. 

 morongiae, R. reticulatae, R. roemerianae, and R. thornberiana. 



Dr. E. A. Burt has recently completed a study of the Thele- 

 phoraceae collected by W. A. Murrill in Mexico, and reports 

 many interesting species, quite a number of whith are new. 

 These will be published in Dr. Burt's series of articles now ap- 

 pearing in the Annals of the Missouri Botanical Garden. 



Helicosporium nymphaearum- is described as new by Frederick 

 V. Rand in the February number of the Journal of Agricultural 

 Research. The fungus causes irregular spotting and decaying of 

 the leaves of various species of pond lilies of the genus Nymphaea. 

 Part of the material on which these studies were based was col- 

 lected in the New York Botanical Garden, although the disease 

 was first noted at Kenilworth, D. C. 



Sorauer has recently made observations on house plants and 

 finds that injury from burning gas in rooms is negligible and is 

 easily avoided entirely by ventilation. The chief injuries are 

 probably due to the elevation of temperature and the drying of 

 the atmosphere by means of fires or heaters. 



Pistillaria Thatf'teri Burt, recently described as the smallest 

 hymenomycete, was found by Professor Thaxter on rotten wood 

 at Westhaven, Connecticut, about twenty-nine years ago. An ac- 

 count of this interesting little fungus appeared in the Annals of 

 the Missouri Botanical Garden for November, 191 6. 



The genus Hypochnus is treated by Dr. E. A. Burt in the 

 Annals of the Missouri Botanical Garden for April, 1916, 31
