458 SUMMARY OF CURRENT RESEARCHES RELATING TO 



history of a number of forms by growing the conidial and ascogenous 

 stages in pure culture. They collected the spores of Glo&osporium from 

 different hosts and produced the ascogenous stage. They could not 

 distinguish any morphological differences, though, probably, as the 

 hosts were so diverse, they are likely to be physiological species. The 

 fungi experimented with were collected from the vine, apple, cranberry, 

 rubber-plant, locust, Ginhjo, cotton, and bean. 



Hyphomycetes.* — G. Lindau has just issued another fascicle of his 

 work. It is mainly occupied with those genera that have brown 

 1-septate spores, the Phajodidymes, which are divided into Bisporese, 

 Cladosporieffi, and Cordanete. The genus Gladosporium claims most 

 attention ; the author has recognised (57 species. Some of them are 

 parasites, but most are saprophytic on various plant-remains. 



Mycolog-y at the School of Pharmacy. — Gr. Bainierf reports on the 

 method of preparing blue cheese by allowing a piece of bread to become a 

 mass of blue mould, and then crumbling some of it into the milk. He urges 

 the necessity of a more exact study of the moulds used industrially, and 

 proceeds to describe exactly, and with accompanying figures, 10 new 

 species of Penicillium collected from various sources — on potato, dead 

 branches, nettle stems, etc. The author lays particular stress on the 

 character of the vegetative hyphfe as aids in diagnosis. He cultivated 

 the species, and describes the method of growth, germination of spores, 

 etc. A new genus of Hyphomycetes, Graphiopsis, is also described and 

 figured. It differs from Graphium in so far as the fertile hyphae are 

 dilated at the extremities and bear a number of conidia. He calls the 

 new form, which grew on rotten wood, G. Cornui. 



Bainier % found other fungi than Penicillium on cheese, one of the 

 most frequent being Spore tidonema Casei, which he redescribes and 

 figures. He also takes occasion to describe two new species of the 

 same genus, S. Solids and S. ArtemisicB, found the one on dead willow 

 stems, the other on dead branches of Artemisia. 



Still another new genus of Hyphomycetes has been discovered by 

 the same worker. § rceciUmijces, near akin to Penicillium and Asper- 

 gillus, and bearing long chains of spores, but differing in the manner of 

 branching. The plant P. Varioti takes a number of growth-forms, all 

 of which are figured. 



Spegazzinia Ornata Sacc.il — E. A. Bessey describes in detail this 

 member of the Tuberculariea3 Dematreas, with its two kinds of conidia : 

 (1) smooth, rather small, conidia, borne at the tips of short conidio- 

 phores, and (2) spiny, cniciate, large conidia, borne on elongate hyphse. 

 Cultures were made, and, in varying conditions, one or other of the 

 spore forms alone was produced. No other fruit form was produced. 

 The illustrations show the different conidia and their germination. 



Ustilag-o Maidis.lT — Chifflot has demonstrated the presence of this 

 fungus in the adventitious roots of Zea Mays. This plant produces the
