ZOOLOGY AND BOTANY, MICROSCOPY, ETC. G73 



New Fungi from the Tyrol.* — P. Magnus describes two new 

 parasitic species : Gercospora Funiculi on Fosniculum officinale differs 

 from other species of Gercospora in the spores remaining non-septate, 

 but the other characters all agree with Gercospora. He also found a 

 parasitic Goniosporium on the leaves of Onobrychis sativa, with large 

 brown conidia measuring 31 fx x 1G— 19/x. Most of the species of this 

 genus are saprophytes, but Magnus thinks there may be many more 

 parasitic species than is generally supposed. 



Hyphomycetes.t — R. E. Buchanan gives an account of the genus 

 Gephalosporium. Species of the genus are common in the humus-rich 

 prairie soils of Iowa. Buchanan isolated and cultivated a new species, 

 G. PammeJii. It produced the usual heads of conidia, but these, when 

 they fed on the culture medium, became much elongated, somewhat 

 crescent-shaped, and 6-8 septate. They then bud and develop similar 

 conidia. The author considers that the genus Hyalopus is the same as 

 Cephalosporium, and that Allantospora is also probably only a growth 

 form. 



Classification of the Hyphomycetes.t — P. Vuillemin publishes a con 

 tinuation of previous work on this subject. Instead of the old divisions 

 Mucedinese, Dematiee, etc., he proposes Thallosporae, Hemisporae, and 

 Conidiosporae. The latter group is the one dealt with. It includes 

 forms in which the spore is sharply differentiated from the vegetative 

 structure. The author lays more stress on the sterigma on which the 

 conidium is directly borne than on the general sporophore. The sterigma 

 he calls the " Phialide." The first order Sporotrichacea; has no sporophore, 

 typified by Rhinotrichum ; the second order Sporophoreae, with a 

 simple sporophore, is represented by Acremonium. The other two are 

 characterized by the branching of the sporophore : they are the 

 Phialideae, of which the type is Botrytis, and Urophialiderc, which 

 includes genera like Coemamiella. 



Green Muscardine of Frog-hoppers.§ — In Trinidad the sugar- 

 cane is damaged bv a fungus Marasmius Sacchari, and also by an insect 



i ill 



Tomaspis postka, called the frog-hopper. The latter is attacked by a 

 fungus determined by Thaxter as Metarrhizium anisoplise. G. B. 

 Rorrer gives an account of this fungus and of his cultures of it on 

 artificial media and on frog-hoppers. The infected insects were killed 

 in five days, and it is believed that the fungus may prove of economic 

 service to the planters in getting rid of the frog-hoppers. 



Thermophilous Moulds. || — Griffon and Maublanc describe two 

 moulds that grew at high temperatures. One, already reported by 

 Miehe as Thermomyces lanuginosus, grew on heated oats, they consider
