observed which are thought to be pathological manifestations, i.e., mycoplasm. — After the 

 two growth phases in the host have passed there comes a time when the fungus gains suprem- 

 acy. Anatomically this is manifest in the dissolution of the chlorophyll granules. Nucleoli 

 of the various sizes appear and mark the end of the mycoplasm stage. Soon the typical 

 hyphal bodies become evident first within the cell and later in the intercellular spaces. — 

 Antheridia and oogonia are formed on the intercellular mycelium and fusion stages are shown. 

 Oospores develop. They can be found in dead tissue mostly singly in the spongy parenchyma 

 or near the lower epidermis. — -The oospores germinate immediately. The germ tube issues 

 from a stomata and, remaining simply or becoming branched, produces spores which function 

 as zoosporangia. — The return of the fungus to the mycoplasm stage remains to be investi- 

 gated.—!). Red dick.

 1918. — Bacillus radicicola isolated from the roots of alfalfa, sweet clover and burr clover al 

 cross-inoculate. Organisms isolated from any one of the 4 clovers, crimson, alsike, red and 

 white produced a vigorous nodule formation by cross inoculation. The organisms of garden 

 peas, vetch, Canada field peas, and sweet peas also cross-inoculate. — J. J. Skinner.

 1918. — The cover of this number bears the photograph of Professor Thomas H. Macbride, 

 accompanied by a brief expression of personal appreciation. Photographs and notes on the 

 following fungi are given: Cordyceps sinensis, Xylaria tuberculosa, X. polymorpha, X.fus.ca, 

 X. stromatica, X. gracillima, Camillea (?) sulcata, Scleroderma sinnamariense, Trametes 

 argyropotamica, Baeomyces roseus, Polyporus myclodes, Trametes pusillus, Exidia uvapassa, 

 Cladoderris thwaitesii, Fomes marginatus, Irpex subcoriacea, Pleurotus sapidus, Camillea 

 bomba, Isaria sphecocephala (?), and Sebacina spongiosa. Comments by correspondents on 

 "Mycological Myths" are appended. A short account is given by N. Gist Gee of the history 

 of Cordyceps sinensis in Chinese medicine and pharmacy. This plant is the celebrated 

 "Chinese plant worm" of Chinese materia medica.— //. M . Fitzpatrick.

 1918. — The photograph of Mr. John Dearness appears on the cover of this number, and is accom- 

 panied by ;i brief biographical sketch. The genus Auricularia is discussed, and a list of the 

 species regarded as worthy of recognition is given. Only eight of the seventy-two named 

 species are recognized. Photographs and notes are given for A. auricula Judac, A. Moellerii, 

 and A. delicata. Three species of Stereum having dark, seal-brown, pubescent pilei are 

 figured and discussed. These are S. illudens, S. deceptivus, and S. Phoca. "Rare and inter- 

 esting fungi received from correspondents" include the following species: Polyporus Wil- 

 sonianus, Secotium pedunculatum, S. tenuipes, S. russuloides, S. australe, Mucronella tenuipes ,
