the ascus with the zoosporangium, nor with the view that the 
Ascomycetes have originated from some such Phycomycetous 
group as the Peronosporineae or Saprolegniineae, an affinity first 
suggested by de Bary on the basis of sexuality. 
The VIII Abtheilung, Erster Band, Rabenhorst's 
Kryptogamen-Flora contains the first installment of Hyphy- 
mycetes by G. Lindau, issued May 16, 1904. The general system 
used by Saccardo is here followed and the first pages of descrip¬ 
tions (beginning with Sarcinomyces, pertain to the Chromo- 
sporieae, a section of the Hyalosporae of the family Mucedinaceae. 
The descriptions of the species are rather brief, some notes are 
added especially in case of important pathogenic species and 
occasional figures in the text are given. Greater convenience 
would accrue had the generic name, especially when the species 
are very numerous, been repeated in full instead of being indi¬ 
cated by the initial letter, or better yet the full name repeated at 
the top of successive pages. 
Many genera, some with a large number of species, e. g. 
of Oidium (which are listed and described though noted in some 
cases as conidial forms of certain Ascomycetous species) are given 
by G. Lindau in 93. Lieferung, Ester Band, VIII Abtheilung of 
Rabenhorst’s Kryptogamen-Flora (pp. 65-128), issued 30 June 
1904. Cephalosporium charticolum is described as a new species, 
and Eidamia is established as a new genus of the Aspergilleae. 
P. A. Saccardo gives Micromycetes americani novi — 
Mycetes boreali-americani a Doct. Fairman lecti (11 new species) 
and Mycetes Mexicana a Doct. S. Bonansea lecti (5 new species) 
— in the Journal of Mycology, March 1906. The diagnoses, 
notes, etc., are in Latin. 
Prof. Dr. F. Bubak describes ii new species of North 
American fungi and one new genus under the title of Einige 
Neue Pilze aus Nord America, Journal of Mycology, March 
1906. The new genus is as follows: Pseudostegia Bubak n. g. 
Melanconiacearum. The type species is P. nubilosa, Lexington, 
Kv., on leaves of Carex sp. — “Ein sehr interessanter Pilz, 
welcher mit meiner neuen Gattung Anaphysomene (Annales 
Mycologici 1906) verwandt ist. . . . “Es ist moglich, dass er als 
Konidienstadium zu Stegia caricis Peck (welche aber mit Stegia 
subvelata Rehm identisch ist) gehort. Es scheint mir dann 
weiter, dass Cryptosporium nubilosum Ell. et Ev. mit meinem 
Pilze identisch ist, denn ich vermute, dass die Breite der sporen 
nur durch einen Druckfehler statt 2.5/A-8.5/A angegeben ist. Sollte 
meine Vermutung zutriffen, dann musste der vorliegende Pilz 
Preudostegia nubilosa (Ell. et Ev.) Bubak genannt werden.”
