SUMMARY OF CURRENT RESEARCHES RELATING TO 
single cell, or may be a compound multicellular structure. It is never 
attached directly to the carpogenic cell ; the fertilising process must be 
carried through one or through several cells before it reaches the carpo- 
genic cell. The cells of the trichogyne communicate with one another 
through strands of protoplasm ; and the author believes that the nucleus 
of the antherozoid must pass the length of the trichogyne from cell 
to cell before finally fusing with the female nucleus of the carpogenic 
cell. 
New Genera of Fungi.* * * § — M. N. Patouillard describes, under the 
name Gyclostomella , a new genus of Hemi-hysteriaccae from Costa Rica, 
with the following diagnosis : — Stromata foliicola, orbicularia, dimidiato- 
scutata, centro adfixa ; peritliecia radiantia, in stromate circulariter dis- 
posita, ostiolis hvsterioideis donata ; sporidia ovata, simplicia, brunnea ; 
mycelium superficial nullum. 
Cryptophallus g. n. is separated from Ithyphallus by Mr. C. H. Peck,! 
on the ground of the volva rupturing in a somewhat circumscissile 
manner, the upper part of it being carried up and remaining on the 
pileus, persistently concealing the stratum of spores. It consists of a 
new American species, C. albiceps. 
Mr. J. D. Ellis and Mr. F. D. Kelsey J separate from JEcidium a 
new genus JEcidiella , distinguished by its uniseptate spores. Several 
species are described. 
From Java, M. E. de Wildeman§ has obtained a new genus of 
Mucorini, which he names Massartia, with the following diagnosis : — 
Mycele ramifying in the substratum fthe mucus of terrestrial Algae) ; 
zygospores produced in a ball of interwoven filaments, which are thicker 
than the other portions of the mycele, globular, formed by the fusion of 
the apices of two mycelial branches; membrane which separates the 
zygospore from the mycelial filaments often thickened ; zygospores 
smooth, with a comparatively thick wall. Sporanges unknown. 
Endophytic in the roots of a Celtis in the forests of Java, M. J. M. 
Janse || finds a fungus, which he regards as the type of a new genus of 
Elaphomycetacem, and names Celtidia duplicispora. The genus differs 
from others of the order in its (probably) parasitic habit, and in its sep- 
tated spores, which do not occur in any other member of the Tuberaceae. 
Tubeuf’s Parasitic Diseases of Plants.^ — An English edition has 
now appeared of this standard work on the Gryptogamic diseases of 
Plants. The 1st part is divided into 9 chapters, viz. : — The Parasitic 
Fungi ; Reaction of Host to parasitic attack ; Relation of Parasite to 
substratum ; Natural and artificial infection ; Disposition of Plants to 
disease ; Preventive and combative measures ; Economic importance of 
diseases in plants ; Symbiosis : Mutualism ; and Symbiosis : Nutricism. 
The 2nd part is devoted to a Systematic Arrangement of the Cryptogamic
