SUMMARY OF CURRENT RESEARCHES RELATING TO 
Uromycetes of the Leguminosae.* — M. P. Hariot describes thirty- 
five species of Uromyces parasitic on various species of Leguminosae, five 
belonging to the section Eu-uromyces, twelve to Hetero-uromyces, six to 
Uromycopsis, and twelve to Lepto-uromyces. 
Puccinia.f — Sig. R. Pirotta proposes a classification of the species 
of this genus under five sections, viz. : — (1) Leptopuccinia, (2) Micro- 
puccinia, (3) Hemipuccinia, (4) Pucciniopsis, and (5) Eupuccinia. The 
first three sections are again divided into species with and species 
without paraphyses. In Pucciniopsis no species is known with para- 
physes. Eupuccinia is again divided into Auto-eupuccinia and Hetero- 
eupuccinia ; in the first there are no species with paraphyses ; the second 
is again divided into those with and those without paraphyses. 
Vascular Hyphae of the Agaricineae. t — From an examination of a 
large number of species belonging to 44 genera distributed through 
the various forms of Agaricineae, M. C. Van Bambeke has arrived at 
the following general conclusions : — 
Some elements, distinct from the fundamental and connecting 
tissues, called laticiferous vessels, sap-ducts, oleiferous vessels, &c., and 
included under the general term vascular hyphse, are to be met with 
probably in all the Agaricineae. The number of the vascular hyphae, 
their dimensions, shape, their arrangement, and course, and the nature 
of their contents, vary according to the genus, and often in the same 
genus according to the species, and in each species in the different 
parts of the carpophore. The vascular hyphae may be found in all 
parts of the carpophore, that is, in the stipe, the pileus, and the lamellae. 
The last subdivisions of the vascular hyphae terminate frequently in 
the lamellae between the elements of the hymene, either in an open 
end or in cystids ; similar terminations are found sometimes at the peri- 
phery of the pileus and of the stipe. The contents of the vascular 
hyphae are often of a complicated chemical composition, and include, 
among other substances, independently of colouring matters, resinous 
substances, fatty matters, albumen, glycogen, and dextrines. The 
vascular hyphae other than the laticiferous vessels of the Lactario- 
Russulaceae, do not deserve, in a general sense, the name of oleiferous 
vessels. From the presence of glycogen in the vascular hyphae, 
especially in their young stage, and from their penetration into the 
different parts of the carpophore, we may conclude that these organs 
play an important part in the distribution of nutritive substances ; but 
it is probable that the vascular hyphae fill yet other functions; con- 
sidering their frequent termination at the periphery (between the 
elements of the hymene, &c.), it may be that they are instrumental in 
the elaboration and excretion of certain fluids or solids. At present 
the vascular hyphae have only been employed, as elements of classifica- 
tion, for the group of the Lactario-Liussulaeeae. They may, however, 
be used with the other Agaricineae, for they may furnish in many cases 
important characteristics, either generic or specific, in the same way as 
the fundamental, connecting, and supporting tissues.
