proved to be a wound parasite : it is very common and very destructive ; 

 it attacks practically all deciduous trees as well as conifers, both livintr 

 and dead. From the mature fungus there is an enormous spore 

 discharge, but the spc»res do not retain viability for more than six and a 

 half months. Cultures were made on wood, and the effect produced by 

 the growth of the fungus was carefully noted. Wood I'otted by this 

 Forms shows a mottled appearance ; this is due to the destruction of 

 the tissues at certain points and the formation of pockets filled with 

 mycelium. In the later stages of decay the fungus was accompanied by 

 bacteria and other fungi. On living trees the fungus was observed to 

 have travelled upward in the heurt wood and outward through the 

 sapwood. It is often quickly destrtictive. A. L. S. 



Polyporaceae of Bengal. Part III.— S. R. Bose {1M\. Garni. Med. 

 Coll. Belf/achia, 1920, 1, 1-5, 7 pis.). The author records twelve 

 different species of Poria, Tramdes, Fomes^ etc. He gives full descrip- 

 tions, habitat, etc. K\\ of those listed grew on dead wood. A. L. 8. 



Mycological Notes for 1919. — L. 0. Overholts {Mycoloi/ia, 1020, 

 12, 1:35-42, 2 pis.). Tlie author comments on the abundant growth 

 of fungi in central Pennsylvania during 1919. Many species have been 

 added to recorded lists, some of them of rare occurrence. It is on 

 some of these that the notes aje based : — Clavaria ornatipes, with brown 

 hairs on the stem ; Merulius aureus^ a rare species on pine ; MucroneUa 

 Ulmi^ a rare species of a rare genus with short awl-shaped teeth ; 

 Treniellodon ueJaUnosuni and others. A. L. S. 



Mycological Notes. I.— F. Petrak {Ann. MycoL, 1919, 17, 59-100). 

 The author discusses a number of fungi (^microscopic) already known, 

 both of Fungi Imperfecti and of Pyrenomycetes. He has also established 

 for both grotips several new genera : — KeissUriana (near to Dotltiora)^ 

 Cutoplacoxphseria^ Psevdopleospora^ Xeolceisslen'a, Ghaetoct/tostronia, BJenn- 

 oriopsis, Macnidiaportlie^ and PJiseodiaporthe. Most of the genera are 

 Pyrenomycetes. Ghsetocytostroma and BJennoriopsis belong to Fungi 

 Impurfecti. A. L. S. 



Mycological Notes. — C. G. Lloyd (Gincinmdi, Ohio, 1919, 2s. 60, 

 S(i2-7(i, :)4 figs.). The present notes are mainly concerned with the 

 genus Fterida, rare in this country and in North America, but more 

 common in the tropics. Lloyd figures and describes all the known 

 species. He then discusses a numbei* of tremellaceous plants, TremeUa, 

 AurmdcD'ia, Exldia^ etc. A. Ij. S. 



Index of the Mycological Writings of C. G. Lloyd.— Ginn'nnati^ 

 Ohio, 1910-9, 5, 1-24, 1 pi.). A subject index of the papers contributed 

 by Lloyd to mycological literature. A portrait of the author is pub- 

 lished. A. L. S. 



Mycological Fragments. — Franz v. Hohnel {Ann. Myrol., 1919, 

 17, 114-38). The author publishes criticisms on a number of estal)lished 

 species. He records the finding of Tricholoma tenuiceps Cke. & Mass. 

 in Vienna woods, the first time it has been found out of England so far
