424 SUMMARY OF GUKRKNT RESEAKCHES RELATING TO 



physical and biological uniformity of the territory and by unfavourable 

 climatic conditions. The lack of species is specially manifest in the 

 fungi that are more particularly humicolous and hygrophilous, such as 

 Hymenomycetes, Phycomycetes, Myxomycetes, etc. The prolonged 

 aridity of the climate favours the existence of species with a short life- 

 cycle and with a rapid development. Parasitic fungi are prevalent. 

 About two hundred species are recorded. A. L. S. 



NotsB Mycolog'icge. — P. A. Saccardo {Nuovo Giorn. Bot. Ttal, 

 1916, 23, 185-234). The author has enumerated 248 fungi submitted 

 to him for determination, of which 76 are new species, 13 new varieties. 

 The collections were made in New York State, the Philippines and 

 Erythrtea, while yet another list includes specimens from various regions 

 — Italy, France, Asia, Africa, Australia, etc. A. L. S. 



Second List of Fung'i from Val S. Martino, or Valle della 

 G-ermanasca— B. Peyronel {Niwvo Giorn. Bot. ItaL, l'J18, 25, 146- 

 92). The list of fungi includes three orders, Hymeniales, Uredinales 

 and Ustihginales. The species, numbering 128. were collected by the 

 author ; 73 are new for the district; one, Bolettis h/ricinus, is new for 

 Italy. Localities are given with biological notes. There is appended 

 an index of the genera, and a second index indicating the habitat or the 

 matrix of the fungi. A. L. S.

Micromycetes of Val Germaiiasca. — B. Peyronel {Niiovo Giorn. 

 Bot. Hal., 1918, 25, 405-68, 76 figs.). The fungi of this list belong 

 to various groups. Many of them are parasites on the plants, and an 

 index of these is appended. The author does not claim that his list is 

 complete. He collected and determined 145 species, 67 of which are 

 new to the district, and 12 new to science. He has described three new 

 genera, Meringosphserea (Sphjeriaceae), Gladographium (Stilbacefe), and 

 Helicockndrwn (Mucedinace^). He also places in a new genus Erio- 

 ineneMa, the species recorded as Menispora Lib&rtiana Sacc. A. L. S. 



Fungi from Val d' Aosta. — P. A. Saccardo {Nuovo Giorn. Bot. 

 Hal., 1921, 24, 81-43). A list of 97 species, most of them Micro- 

 mycetes ; 60 of the species determined are new to the district, and eight 

 are new to science, with one new genus, Nothodisrus (Phacidiacese), 

 found on living leaves of Veronica. Two species of Mycetozoa are 

 included. A. L. S. 



Micromycetes from Piedmont. — Alberto Noelli {Nuovo Giorn. 

 Bot ItaL, 1921, 24, 183-97). The list is the third contribution by 

 the author to the fungi of Piedmont. He describes four new species, 

 parasites of the higher plants. One of these, Gladosporivm acerinum, is 

 akin to C. epiphyllum. The list also includes ten Mycetozoa. A. L. S. 



Fungi of our Common Nuts and Pits. — Charles E. Fairman 

 {Proc. Rock. Acad. Sci., 1921, 6, 73-115, 6 pis.). The author describes 

 the fungi that he has found growing on chestnuts, various nuts, acorns, 

 and on " cherry pits " (stones) and " peach-pits." He has listed and
