NOTES FROM MYCOLOGICAL LITERATURE. V. 
W. A. KELLERMAN. 
New Species of Fungi by Charles H. Peck, Bulletin of 
the Torrey Botanical Club (30:95-101, Feb. 1903), includes 17 
species of the higher Fungi belonging to as many genera. A 
new Genus, namely Mitruliopsis, is proposed. The Morchella 
described (M. punctipes) is said to be closely allied to M. semili- 
bera but has larger spores and a squamulose stem. 
Fasciculus II of Volumen I, Monographia Uredinea- 
RUM, P. et H. Sydow, dated 15 Nov. 1902, is the second install¬ 
ment of the genus Puccinia, pp. 193-384, species numbers 303-595, 
ending with the hosts of family Umbelliferae. There are eleven 
full-page plates of outline spore-figures all drawn to the same 
amplification. Where several Rusts occur on species of the same 
genus a conspectus specierum is always given. A large number 
of new species and new names are proposed; of the former six, of 
the latter three pertain to North American Rusts. 
A Good Monograph of the Ravenelias of the United 
States and Mexico, by William H. Long, Jr., is published 
in the Botanical Gazette, 35:111-133, pi. II and III, Feb. 1903. 
Keys are given to the three genera, and to the species of Ravenelia 
(19) and of Pleoravenelia (6). Two new genera are proposed, 
namely, Pleoravenelia and Neoravenelia, the former having six 
species, the latter one. All the species are fully described,, full 
synonomy given, hosts and localities enumerated. The species are 
figured on two double-page plates. The preface gives the dis¬ 
tribution of the known species, the methods in preparing the 
spores for examination (boiling in lactic acid), refers to previous 
work on the group, and makes acknowledgments for assistance. 
A Destructive Apple Rot Following Scab is detailed by 
H. J. Eustace in N. Y. Agr. Exp. Sta. Bull. 227^367-389, PI. I- 
VIII, Dec. 1902. The fungus, which is the cause of the Rot, is 
Cephalothecium roseum Cda., generally regarded as a saphro-
