SUMMARY OF CURRENT RESEARCHES RELATING TO 
New Genera of Fungi.* * * § — M. A. Giard describes the following new 
genera and species of entomoplithorous fungi — EpicJilcea divisa , on the 
body of an Ephemeron ; it is composed of short cylindrical cells, bear- 
ing one or two spores at each of their extremities ; Halisaria gracilis, 
on larvae of a Dipteron ; it is formed of slender slightly branched 
filaments, bearing greatly elongated ovoid-cylindrical spores at their 
extremity. A fungus, previously described as Metarhizium, found 
on the larvae of Li par is chrysorhea, he now names Chromoslylium 
chrysorhese. 
Sigg. Berlese and Bresadolaf separate the genus Morinia from 
Pestalozzia by its muriform spores. They consider that Langloisula 
spinosa g. et sp. n., described by Ellis and Everhart, hardly differs 
from Mouosporium or Monilia. 
Fungus-parasites on Acridium peregrinum.i — MM. J. Kiinckel 
d’Herculais and C. Langlois identify the fungus parasitic on this 
locust as nearly allied to Polyrhizum Leptophyei Giard. They state, 
however, that with this, as with other Acrid ia, the parasitism is en- 
tirely superficial and not morbific ; and that death is caused, in most 
cases, by the attacks of a parasitic dipteron, Sarcopliaga clathrata. 
M. L. Trabut § enumerates the various fungi which are parasitic 
on Acridium peregrinum, viz. (1) Botrytis acridiorum Trab. (Lachnidium 
acridiorum Giard); (2) Cladosporium herbarum var. ; (3) Saccharomyces? 
parasitaris, found among the spores of the Lachnidium; (4) Oospora 
ovorum sp. n., a Hyphomycete which forms a white efflorescence, and 
produces groups of 20-30 long chaplets of spores. It does not 
appear to have any injurious effect on the development of the locust. 
Parasite of the Cockchafer-larva. || — M. A. Giard identifies the 
fungus parasitic on the larva of the cockchafer as Lsaria densa, and 
asserts that the silkworm can be inoculated with it ; it does not, 
however, readily produce spores on this host, but passes over into the 
sclerote condition. 
M. Le Moult ^ describes further experiments in the cultivation of 
this fungus on artificial media, and reasserts its specific distinction 
from Botrytis bassiana, parasitic on the silkworm. 
New Genera of Lichens.** — Herr J. Muller describes 37 new species 
of lichens found on the leaves of flowering plants or of ferns, and 
establishes from them eight new genera. Calenia is separated from 
Lecania, and Tapellaria from Patellaria, by the wide-meshed structure 
of the thalamium, and Asterothyrium from Patellaria by the stellate 
mode of opening of the disc. The five remaining new genera aro 
characterized by the common characteristic of a Phyllaclidium-\ ike
