and they increase in storage. These, with the wild yeasts and bacteria, 

 can be eliminated by crushing the grapes and adding moderate amounts 

 of sulphurous acids. Good fermentation should be assured by the use 

 of pure selected yeast. A. L. S. 



Endophytic Fungus of Lolium. Part I. — Ethel McLennan 

 {Proc. Roy. Soc. Victoria, 1920, 32, 252-301, 9 pis., 8 figs.). The 

 presence of a fungus in the grains of Lolium has long been known ; the 

 present writer considers that it is probably a case of symbiosis, somewhat 

 similar to that of Calluna. In the latter plant the fungus — distinctly 

 symbiotic — is intra-cellular ; that it is also intra-cellular in Lolium has 

 now been demonstrated. The growth of the fungus keeps pace with 

 that of the plant ; the hyphag, however, are mainly restricted to the 

 growing apex. When the inflorescence is formed, they are abundant at 

 the base of the carpels, and are present in the embryo-sac at or immedi- 

 ately after fertilization On the formation of endosperm the 



fungus is absorbed as a source of food-supply to the developing embryo. 

 " The fungus of Lolium perenne was unalile to fix nitrogen in the total 

 absence of external supplies of combined nitrogen." A. L. S. 



New or Noteworthy Porto Rican Fungi. — F. L. Stevens {Bot. 

 Gaz., 1920, 70, o99-482, 4 figs.). The first species, AnLhostomella 

 Ehizomorphse B. & V., had been recorded on "coriaceous" leaves, 

 Stevens has now determined the host plant and gives a full description. 

 It grows on leaves and excites the tissues to gall-like outgrowths. One 

 new genus, Trahutiella, was discovered ; it is similar to Trahutia, but 

 with sixteen spores in the ascus. Several new species or forms are also 

 described. A. L. S. 



Sequence of Fungi and Mycetozoa. — W. T. Elliott and J. B. 

 Elliott {Jouni. Dot, 1920, 58, 27;'5-4). The writers have kept under 

 observation an oak branch blown down in 1912. In the autumn of 

 1913, after lying on the ground in a conifer plantation for twelve 

 months, it was profusely covered with the black gelatinous ascocarps of 

 Bulgaria polymorpha. Gorym sarcoides appeared later, then Stereum 

 hirsutum and other forms. In the autumn of 1919 the first mycetozoon 

 appeared, a der)se growth of Physarum nutans spreading over an area 

 of about four square feet. Other fungi continued to develop, and in 

 July 1920 the second mycetozoon, Stemonitis fusca. The luxuriant 

 growth of Physarum nutans, with the disappearance of Bulgaria poly- 

 morpha and Goryne sarcoides, lead the authors to the conclusion that 

 Physarum must have lived on and exhausted the hyphae of the fungi.

Some New Hampshire Fungi. — L. 0. Oveeholts {Mycoloyia, 

 1921, 13, 24-37). Collections in the above district had been made in 

 1884 by Dr. Farlow, who listed 107 species distributed through 03 

 genera. Overholt's collection furnished 195 species with about 77 

 genera, but only about a dozen species are duplicates of those collected 

 by Dr. Farlow. This is explained by the statement that while the latter 

 collected the smaller fungi, Overholts gave his attention more particu- 

 larly to Basidiomycetes. He notes as of special interest a fungus that
