France, vol. 7, No. 2. Paris, June 30,1891,'pp. 111-115. Notes the presence of 
paraphyses in pycnidia of Dothicizapopulea, Sacc., Fusicoccumpopulinum, De- 
laer., Fusicoccum complanatum, I)ela., Fusicoccum pini (Pr.), Sacc., Stilbospora 
angustata (Pers.), Sacc. Concludes that in a certain number of pycnidia or 
spermogonia the appearance of paraphyses follows the emission of spores, 
and this is perhaps the first step toward the development of the pycnidia 
into the ascosporous stage. Notes also the discovery of a new fruiting form 
of Stephanome strigosum, (Wallr.) Sacc., and mentions finding the spermo¬ 
gonia of Uredo Mulleri, Schrcet. (E. A. S.)

In higher plants four systems of tissue are distinguished—meristematic, pro¬ 
tective, nutrient, and reproductive. The paper sums up the results of an at¬ 
tempt to trace the four systems in the class of fungi. (E. F. S.)

vol. 7, No. 2. Paris, June 30, 1891, pp. 99-101. Describes the opposite and 
alternate hyphopodies, and gives the opposite the name of capitate, and the 
alternate ofmucronate hyhopodies. Shows that the former are undeveloped 
perithecia, and the latter mycelial branches arrested in their development.

dium perigrinum. Comptes Rend., Soc. Biol., new ser., vol. 3, Paris, June 25, 
1891, pp. 493-496. Notes the fungus described in No. — as Polyrhizium 
leptophyci, also a similar fungus on different parts of the same insect and 
having spores arranged as in Verticillium. Suggests that this may be another 
form of the first species, but does not unite them, as there is insufficient evi¬ 
dence. Both are superficial fungi. Finds a white Penicillium, which is 
undetermined. The author also recounts an infection experiment made by 
inserting some of the spores of the Isaria of the white worm into the larvfe 
of the locust. Both the infected and the check larvae died, but the dead bodies 
of the former produced a growth of the fungus when kept in a moist place. 
Keeping the bodies moist is, however, necessary to the appearance of the 
fungus, indicating that there is little hope of utilizing this Isaria or any other 
parasite of the same group in combating the locusts of Algeria. There are 
probably less chances of success with Fntomophthora grylli, Fresen. (F. calop- 
teni, Bessey), as even the few instances of apparent success need further 
verification. (E. A. S.)

new ser., vol. 3, Paris, April 17, 1891, pp. 236-238. In June, 1890, the author 
received from Ceauce (Orne) specimens of the “ white worm” infested by a 
parasite, which proved to be an Isaria of doubtful species. It had proved 
very destructive to the larvae, spreading so rapidly and killing so many as 
to decidedly improve vegetation over the areas where the fungus was pres¬ 
ent. Experiments showed that the spores rapidly communicated the disease 
to tire white worm and to the larvae of Tenebrio molitor both by inoculation 
and spraying. On artificial media the fungus was easily cultivated, even 
conquering other fungi that invaded the cultures. The spores retained tlieir 
germinating power from October until the following March. The culture 
experiments were made on solid media, but experiments in growing the 
fungus on liquid media have been undertaken in the hope of facilitating 
spreading the spores over areas infested with the grubs. (E. A. S.)
