Studies on the Tremellineae of Wisconsin. — In his studies of 

 the Tremellineae of Wisconsin in the transactions of the Wis- 

 consin Academy of Sciences, Arts and Letters, volume i6, part 

 2, E. M. Gilbert has brought together the species of the order 

 from that state in such a way as to be of valuable service to the 

 student of mycology and to the monographer of the group. He 

 has included the descriptions of fifteen species, quoting the com- 

 monly accepted synonyms. He finds in addition species in 

 Tachaphantium, Tremella and Dacryomyces which he thinks may 

 be new and possibly new varieties of Auricularia auricula, 

 Dacryomyces deliquescens and Calocera cornea. His conservatism 

 in that he has refrained from giving them new names without 

 further investigation is commendable. 



Naematelia cncephala which he states has not been reported 

 before for this country was frequently collected by Mr. Ellis and 

 was distributed by him in North American Fungi i/ip. Also 

 Naematelia nucleata which according to Gilbert has apparently 

 not before been reported from this country was issued by Mr. 

 Ellis in North American Fungi j20. 



A more extended study of exsiccati would have enabled him to 

 suggest additions to the synonymy of several species, as his ac- 

 count probably covers most of the species ordinarily found in the 

 country. — B. O. Dodge. 



A Biologic and Taxonomic Study of the Genus Gymnospo- 

 rangiuni. — Volume 7, No. 26, of the Bulletin of the New York 

 Botanical Garden, issued October 12, was entirely devoted to a 

 paper under the above title by Dr. F. D. Kern, associate botanist 

 in Purdue University Agricultural Experiment Station, Lafayette, 

 Indiana. This subject is treated in two parts, the first being de- 

 voted to the biology of the genus and the second to its taxonomy. 



Under the subject of the biology of the genus the life history of 

 Gymnosporangium as compared with other rust genera, the gen- 

 eral characters of the genus, nuclear history so far as it is known, 

 and facts governing the distribution of the species are considered 

 briefly. Under experimental investigation the author gives a 

 brief account of the history of experimental work and the dis-
