MISSOURI BOTANICAL GARDEN BULLETIN 19 
has proved an important limiting factor in the cultivation 
of cabbage, especially in Wisconsin. In this study the path- 
ogenicity of the fungus Fusarium conglutinans as the causal 
organism is established, and the effect of temperature on the 
inception and prevalence of the disease is emphasized. 
Greenman, J. M. (Ann. Mo. Bot. Gard. 3:201-202), has 
described Senecio Hollickii, a species of Hawaiian origin, 
reported by Britton from Jamaica. New material enabled 
the author to separate it satisfactorily from S. Swartzii, with 
which he had formerly merged it. 
Overholts, L. O. (Ann. Mo. Bot. Gard. 3:195-200), has 
described four new species and one new variety of gill-bear- 
ing fungi, all being members of the fleshy fungi collected 
in the vicinity of St. Louis within the last few years. 
Palmer, E. J. (Ann. Mo. Bot. Gard. 3:345-401), has pre- 
poe a catalogue of the plants of Jasper County, Missouri 
ased upon collections made from 1901 to 1913. In all 
cases specimens have been deposited in the herbarium of the 
Garden, and as far as possible duplicates have been distrib- 
uted to other herbaria. The list is an extensive one for this 
region, a “meeting ground” for various floras, but it is not 
regarded as a complete enumeration of the flora. 
Zeller, S. M. (Ann. Mo. Bot. Gard. 3:439-512), has com- 
pleted a phase of his investigation on the activities of fungi 
inducing decay in structural timber, and the article men- 
tioned considers particularly the physiological relations and 
digestive capacities of the fungus Lenzites saepiaria. Much 
new evidence is given in reference to the enzymes of such 
organisms, and especially interesting are the indications 
showing the relative activity of mycelium and sporophore 
in the contribution of enzymes. This more fundamental 
et is preliminary to a more practical investigation of 
urability in wood. 
HERBARIUM 
Substantial progress has been made in the herbarium dur- 
ing the year. Important new material has been acquired, 
and a beginning has been made towards the replacement of 
the old wooden cabinet cases on the third floor with modern, 
fireproof, steel cases to conform with those already in use on 
the second floor; and one room has already been completely 
equipped with the new cases which at present are adequate 
to accommodate the ferns and the immediately allied groups. 
The appointment of Mr. J. C. Th. Uphof to the herbarium 
staff has facilitated the work of identification and distribu- 
tion. gy
