SUMMARY OF CURRENT RESEARCHES RELATING TO 
mycetes (Ascomycetes) are divided into the Haplothecise (Glycocymacese 
[Saccharomycetes], Taphrinacese, Gymnoascese, and Laboulbeniaceae), 
Endotliecise (Tuberacese and Pyrenomycetes), and Ectothecise (Hysterinese 
and Discomycetes). A corresponding classification is made of the 
Basic! iomycetes into the Haplobasidiese (Ustilagineze and Exobasidiacese), 
Endobasidiese(EcchynsiCGse, Hymenogastreae, Lycoj>erdace9e, N idulariacea^, 
Battareaceae, and Plialloidaceae), and Ectobasidiese (Pucciniaceae, Auricu- 
lariaceae, Tremellacete, Caloceraceae, Clavariaceae, &c.). 
New Genera of Fungi.* — Dr. C. v. Tubeuf finds the leaves of 
the larch attacked and destroyed by a parasitic fungus Hypodermella 
Laricis g. et sp. n., which he makes the type of a new genus dis- 
tinguished from Hypoderma by the unicellular tear-shaped spores, four 
of which occupy each ascus. To the same genus belongs also Hypo- 
derma subsigenum. 
Herr H. 0. Juel f founds a new genus of Gasteromycetes, Hemigaster, 
on a fungus inhabiting the excrement of rabbits and guinea-pigs. The 
fructification is round, closed, and fixed to the substratum by a short 
stalk ; it contains a single chamber penetrated by a columel ; the 
peridium is simple and very loose. The columel is simply a pro- 
longation of the stalk, and passes over above into the peridium. The 
peripheral wall of the chamber is clothed with a basidial layer. From 
the central wall of the chamber, or columel, proceeds a dense weft of 
hyphae which produces chlamydospores, and subsequently fills up the 
chamber. The basids are unicellular, and bear four terminal smooth 
very pale flesh-coloured spores. The chlamydospores resemble the 
basidiospores, but are enveloped in short hyphal branches. 
Herr P. A. Karsten J describes the following new genera of Fungi 
from Finland : — 
Grandiniella. Hymenium udum, subgelatinoso-ceraceum, siccitate 
corrugatum v. rimosum, granulosum ; granulis liemisphaBricis, mollibus ; 
cystidia subuliformia v. fusoidea ; sporae ellipsoideae v. oblongatae. 
Chsetostromella. Sporodichia erumpenti-superficialia, pulvinata, setu- 
losa, atra ; conidia pedicellata, ellipsoidea, muralia, fuliginea. 
M. A. Dewevre § establishes a new genus of Mucorini, Carnoya , 
founded on Mortierella capitata. 
Parasitism of Peronospora parasitica.|| — Herr P. Magnus points 
out that this parasitic fungus may produce quite different forms of 
disease in the host according to the age of the latter. The observations 
were made especially on the wallflower. The same is true also of other 
species of Peronospora. 
Parasitic Fungi. — Herr B. Frank % states that a very destructive 
disease of rye is due to the attacks of Leptosplieeria herpoirichoides , not 
hitherto known as a parasitic fungus. The effects are very similar to 
those produced on wheat by Ophiobolus herpotricJms. The same author
