664. Mtjrrill, William A. Corrections and additions to the polypores of temperate North 

 America. Mycologia 12: 6-24. 1920. — Since the publication of the polypores in the North 

 American Flora much additional information has been obtained on this group involving clearer 

 identity of some of the forms previously described and adding a number of species not pre- 

 viously listed. Various changes are accordingly made or suggested involving the reclassi- 

 fication of numerous forms. — H. R. Rosen. 



665. Mtjrrill, W. A. Fungi from Hedgcock. Mycologia 12: 41-42. 1920.— Twelve 

 species of polypores collected by Hedgcock and others are listed. — H. R. Rosen. 



666. Mtjrrill, W. A. Collecting fungi at Yama farms. Mycologia 12: 42-43. 1920 — 

 Describes an interesting collecting tour in a large tract of virgin land near Poughkeepsie, 

 New York. Nearly 100 species of fungi were collected and several of the more interesting 

 polypores and agarics are mentioned.—//. R. Rosen. 



667. Mtjrrill, W. A. Trametes serpens. Mycologia 12:46-47. 1920. — American speci- 

 mens referred to Trametes serpens Fr. are found to have smaller pores and are "otherwise 

 distinct" from those of Europe. The distribution of the American plant is given and it is 

 compared with a Philippine specimen, Elmeriana setulosa, which it seems to match. — H. 

 R. Rosen. 



668. Mtjrrill, W. A. The genus Poria. Mycologia 12: 47-51. 1920.— Historical sketch 

 of the genus Poria as used by mycologists before the time of Persoon together with Persoon's 

 interpretation of thegenus is presented. P . medullapanis (Jacq.) Pers., one of the species upon 

 which Persoon based the genus, is thoroughly described, its variations noted and a large num- 

 ber of American collections of this species which were examined by the writer are listed. — 

 H. R. Rosen. 



669. Murrill, W. A. Collecting fungi near Washington. Mycologia 12 : 51-52. 1920.— 

 Brief notes of mycologists and of a few fleshy fungi seen during a collecting trip around 

 Washington, D. C.—H. R. Rosen. 



670. Northrtjp, J. H., Lauren H. Ashe, and R. R. Morgan. A fermentation process 

 for the production of acetone and ethyl alcohol. Jour. Indust. Eng. Chem. 11: 723-727. 2 fig. 

 1919. — The general characteristics of a new organism, Bacillus acetoethylicum, are givien ac- 

 cording to the descriptive chart of the Society of American Bacteriologists, but a formal diag- 

 nosis is postponed for a later paper. [See Bot. Absts. 4, Entry 1515.] — B. M. Duggar. 



671. Olivier, H. Les lichens pyrenocarpes de la flore d'Europe. [The pyrenocarpic 

 lichens of Europe.] Bull. Geog. Bot, 28: 146-152, 168-183. 1918.— First two installments 

 of a compilation of all the described genera, species, and varieties, of pyrenocarpic lichens 

 of Europe, with keys and diagnoses. The two parts cited include the genera Normandina, 

 and Endocarpon (taken in a broad sense), and the key to Polyblastia.—L. W. Riddl .

 disease of tomato. Ann. Appl. Biol. 6 : 183-202. PL 8-9, 5 fig. 1919.— See Bot Absts. 5, Entry
