with its ciliated spores, Septonema princeps B and Br., considered, 
probably with justice, by Tulasne, as a stylosporous state of 
Massaria eburnea Jul ; the Genus Pestalozzia of De Notaris, with 
ciliated spores, and Cheirospora F7., having spores connected in 
bundles, seated on the tips of hyaline threads, and immersed in 
gelatine, the connection of which with any ascigerous species has 
never yet been traced out; or, amongst the Torulacei, the 
Genera Bactridium, Helicosporium, Sporoschisma, Dictyosporium, 
and the very rare Tetraploa on grass stems, Bloxamia, whose 
true position in the series is doubtful, all present us with 
points of interest not general among the Coniomycetes. We come 
next to the Order Pucciniei, the species of which are produced on 
living plants, and constitute some of the greatest scourges of the 
human race, and whose history, as worked out by Tulasne and De 
Bary* and other writers, is of the highest interest. Many of the 
plants of this Order are very widely spread, as, for instance, 
Puccinea graminis P. Corn-mildew, which is only too common in 
our cornfields, extends south to New Zealand.  Trichobasis 
linearis Lév, another pest to agriculture, is considered by Tulasne 
to be merely an early condition of the last ; it is commonly known 
as Rust, but in some cases there are two distinct forms of fruit 
included in the spots of mildew. Tilletia caries Ju/, known as 
Bunt, occupies, with its foetid spores, the whole interior of grains 
of wheat, and, if it were not checked by steeping the seed-corn 
before it is sown, would spread to such an extent as to render 
the whole crop unfit for food ; fortunately, a solution of corro- 
* De Bary endeavours to prove by experiment that the Uredo-spores and 
Teleuto-spores (Puccinia) of Puccinia graminis are developed on graminiz only, 
but that the germinative threads which arise from the sporidia contained in the 
Teleutospores that have survived the winter, will only vegetate on the leaves 
of the berberry, and that they produce there Ecidium berberidis. He considers 
that the AScidium is a mere transitional form of Puccinea graminis. The 
AKcidium spores sown on leaves of grasses germinated and produced plants of 
the Uredo,—A. S. N. V. V. 262,
