two different methods of division in the four promycelial nuclei. 
Copulation takes place between the first four cells of the promycelium 
in Cintractia, and that also may occur in two different ways — between 
two neighbouring cells or between the two end cells. Urocystis Violse 
resembles U. Anemones, as described by Knieps, only in the former 
there are formed generally eight primary and four secondary bi-nucleate 
spores. In Dassansia Sagittarise the bi-nucleate stage appears first 
before spore formation, somewhat as in Ustilago Maidis. A. L. S. 
Notes on Coleosporium. I. — G. G. Hedgcock and N. Rex Hunt 
(. Mycologia , 1922, 14 , 244-57, 2 pis.). The authors have made inocu- 
lations of a series of species of Coleosporium , the aecidia of which grew 
on various pine needles. The species inoculated are given and the 
results obtained in each case, and the different species are compared.

Urocystis Agropyri on Redtop. — W. H.- Davies ( Mycologia , 1922, 
14 , 279-81, 1 fig.)* The smutted plants of redtop {Agrostis palustris) 
were collected at Madison, Wisconsin. The fungus grows on a con- 
siderable number of grasses ; its occurrence is duly recorded. A 
special description is given of the spore-balls, etc., of U. Agropyri.

New Japanese Fungi. — Tyozabur6 Tanaka {Mycologia, 1922,14, 
282-95). These fungi are all species of Gymnosporangium. Tanaka 
gives full descriptions with localities, collectors, etc. He winds up with 
a synoptic key of the species. A. L. S. 
Basidial and Oidial Fruit-bodies of Dacryomyces deliquescens. 
— A. H. R. Buller {Trans. Brit. Mycol. Soc., 1922, 7, 226-30). The 
two species known as Dacryomyces stillatus (orange-red) and D. deli- 
quescens (yellow) had been identified by Tulasne as stages in the life- 
history of one fungus. The discovery was confirmed by Brefeld, and in 
the present paper the life-history is given, and the two forms described 
in detail. Both forms grow on rotten wood and are of frequent occur- 
rence. The darker form (orange-red) bears only oidia ; the yellow 
form basidiospores, which develop very quickly and are simple when 
mature, but after lying in water for some time they become 3-septate. 
Buller noted that the yellow fruit-bodies were very pale or almost 
•colourless in the shade. A. L. S. 
Rhizopogon diplophloeus in Washington. -Sanford M. Zeller 
{Publ. Puget Sound Biol. Station, 1918-20, 2 , 95-6). This Rhizopogon 
was described by Zeller and Dodge from Western Washington ; a fuller 
account of the fungus is now given. A. L. S. 
Secotium acuminatum in France. — M. Barker {Bull. Soc. Mycol. 
France , 1922, 38 , 29-30, 2 figs.). This rare member of Gastromycetes 
was found by the author at Lux, near to Dijon, on calcareous earth 
near a wood. Its presence there might be explained by the neighbour- 
hood of an American cavalry camp. The species has been reported 
from Algiers, Russia and Central Asia. A. L. S.
