SUMMARY OF CURRENT RESEARCHES RELATING TO 
disc is gymnocarpous, the basids are septated transversely, the number 
of cells varying up to nine. 
In the Dacryomycetes, the author sinks the genera Dacryomitra , Gue- 
pinia , and Ditiola , in Calocera , retaining only that genus and Dacryomyces. 
Among the Tremellineae, a new genus Clavariopsis is described, 
allied to Tremella , and with its typical basids, hut resembling Clavaria 
in the form of the fructification. Several other new species are described. 
The genus Exidiopsis is sunk in Exidia. 
In discussing the phylogenetic relationship of the various families of 
Fungi, the author criticises unfavourably in several points the conclusions 
of Brefeld ; laying far less stress than does that author on the mode of 
fructification in determining relationship. He believes there exist 
sharply defined groups of Fungi, which have very little or no recognisable 
relation to one another. 
Actinomucor, a New Genus of Mucorini.* — On pigeon’s excrement 
Herr W. Schostakowitsch finds a saprophytic fungus, easily cultivable 
on the bodies of flies in water, which he makes the type of a new genus, 
with the name Actinomucor repens g. et sp. n. It differs from Mucor in 
its very long and slender branched sporangiophores, the branches being 
frequently in whorls, and ending in a single larger sporange, surrounded 
by a whorl of smaller ones. No mode of sexual reproduction is de- 
scribed. 
Endomyces albicans, f — M. P. Vuillemin has studied the develop- 
ment of this fungus, the cause of the disease of plants known as 
“ muguet.” It produces both exogenous and endogenous spores ; but the 
true organs of reproduction are asci, which are spherical or ellipsoidal, and 
usually contain four spores, rarely two or three, of a flattened elliptical 
form. From this limitation of the number of spores, he rejects the vari- 
ous positions which have hitherto been assigned to this fungus, in the 
genera Oidium , Spirotrichum , Stemphylium , My coderma , and Monilia, and 
on other considerations its alliance with Saccharomyces ; and places it in 
Endomyces among the true Ascomycetes. 
Parasitic Fungi. — M. A. Prunet * gives a detailed account of the 
injuries inflicted on the vine by the black-rot, for which he adopts the 
name Guignardia Bidivellii, of the life-history of the fungus, and of the 
internal and external conditions which render the host-plant especially 
liable to its attacks. 
M. L. Mangin § finds a disease of the base of the haulm in wheat to 
be due to the attacks of two parasitic fungi, Opliiobolus graminis and 
Leptosphseria herpotrichoides, which penetrate the lowermost internodes 
of the stem, or in some cases, the root. 
Mr. J. W. Peed || describes in detail the secidioform of Uromyces 
Pisi occurring on Euphorbia cyparissias. 
To the small known number of species of Synchytrium parasitic on 
Monocotyledons, Herr F . Bubak adds a new species, S. Niesslii , found 
on Ornitliogalum umbellatum.
