heretofore grouped with fungi, produces conidia as well as asco- 
spores. The conidiophores are branches, each extremity bear¬ 
ing 2-4 conidia; these are fusiform slightly curved, hyaline, 3-5- 
septate and 50 x 4^. Hence the plant was called by Corda a 
Fusarium (F. biasolettianum) ; it was placed by Fries in the 
genus Pionnotes (type, Fusarium capitatum Schw.), and in the 
Sylloge included in the Tuberculariaceae. The authors create 
a new genus of Lichens, namely, Chrysogluten, which includes 
two of four recorded species of Pionnotes, namely, C. biasoletti¬ 
anum (Corda) and C. casatii (Thiim.) —placed in a new family, 
Chrysoglutenaceae . 
Bacteria, Yeasts and Molds in the Home, by H. W. 
Conn has been recently published (1903) by Ginn & Company of 
Boston. This is a useful book of 293 pages suitable for general 
readers and for classes in educational institutions. Bacteria are 
treated on pages 100-125. 
The Aecidium of Maize Rust, J. C. Arthur, Botanical 
Gazette, July 1904 (pp. 64-7), is an interesting account of a clue 
to the connection of Aecidium on Oxalis with Puccinia sorghi 
Schw., and the culture experiments verifying the same. It is 
remarkable that the Aecidium oxalidis Thiim. should have been 
so rarely collected since the Maize Rust is both common and 
often abundant. Can it be that this stage in the life cycle is 
generally suppressed? 
An Extended and Illustrated Account of the Water- 
Relation of Puccinia asparagi, is given by Ralph E. Stone 
in the July No. of the Botanical Gazette, 1904, (pp. 19-43), as 
“a contribution to the Biology of a parasitic fungus.” The 
study was made in California; it is shown that dew is of abso¬ 
lute necessity in infection by the rust and of more importance 
than the rain; without such moisture no infection can take place. 
Dry atmosphere checks aecidial development; uredo develop¬ 
ment is similarly checked, and changes to a production of teleu- 
tospores. An abundance of soil moisture during the summer 
has a marked effect in retarding the development of this fungus 
by giving the host greater vitality and resistance. 
Bruce Fink gives Further Notes on Cladonias, III, Cl. 
furcata and Cl. crispata, in the July No. of the Bryologist. 
Many varieties are enumerated in the light of Wainio. Cladonia 
furcata and five varieties, also one variety of Cl. crispata, are 
figured. Professor Fink says “regarding the illustrations, we 
are fortunate enough this time to be able to give them all from 
material that has been examined by Dr. Wainio.” 
Under the title of Mycological Notes in the Journal 
of Efotany, p. 182, Ernest S. Salmon gives an account of the
