Deane B. Swingle Gives His Studies in Spore Forma¬ 
tion in the sporangia of Rhizopus nigricans and in Phycomyces 
nitens in Bulletin 37 (pp. 1-40) U. S. Department of Agricul¬ 
ture, Bureau of Plant Industry. The article is illustrated by six 
lithographic plates. After a resume of work previously done on 
the Mucorineae by Corda (1838), van Tieghen (1873-6), Stras- 
burger (1880), Biigsen (1882), Leger (1896), Thaxter (1897), 
Harper (1899), and Hans Bachmann (1899), touching the life 
history and gross anatomy of nearly all the species — there be¬ 
ing “in regard to the cytological details the widest difference of 
opinion, chiefly owing to the fact that only a few forms have 
been studied with the aid of the most recent methods” — Mr. 
Swingle details his work on the two species, followed by eight or 
nine pages of general considerations and summary, also a page 
of Index to Literature. It is interesting to note that in the 
four genera of Mucorineae most carefully studied no two are 
alike in respect to the processes of spore formation. 
Annales Mycologici, Vol. I, No. 3, Mai 1903, contains the 
following articles: Guilliermond, Contribution a l’etude de 
l’epiplasme des Ascomycetes et recherches sur les corpuscules 
metachromatiques des Champignons; Patouillard, Note sur trois 
Champignons des Antilles; Maire et Saccardo, Notes mycologi- 
ques; Saccardo, Una malattia crittogamica nelle frutta del man- 
darino (Alternaria tenuis, forma chalaroides Sacc.) ; Traverso, 
Diagnoses Micromycetum' novorum italicorum; Sydow, Beitrag 
zur Pilzflora des Litoral-Gebietes und Istriens; Bubak, Zwei 
neue, Monocotylen bewohnende Pilze; Dietel, Bemerkungen liber 
die Uredineen-Gattung Zaghouania Pat. 
Dass ein Verhaeltnismaessig Grosser Prozentsatz der 
Pilze doppelt und mehrfach, oft in ganz verschiedenen Gat- 
tungen beschrieben ist, leidet keinen Zweifel, is the keynote to an 
article by Franz v. Hohnel, in Beiblatt zur Hedwigia, 42 :(i 85)- 
(188), July 4, 1903, entitled Mykologische Irrtumsquellen. It 
is really a second communication on this subject; — and there as 
here many cases are enumerated and corrected.

Journal of Mycology concerning this fungus. As to the svste-
