SUMMARY OF CURRENT RESEARCHES RELATING TO 
Sphseropsidese parasitic on Dianthus.* * * § — M. C. A. J. A. Oiulemans 
reduces all the species of Sphaeropsidere which are known as parasites 
on leaves of the European species of Dianthus to two — Ascochyta Dianthi 
Lib., and Septoria Dianthi Desm., regarding Depazea Diantjii Rab., 
Phyllosticta Dianthi West, and Dimemasporium Dianthi Oud. as syno- 
nyms of the former, and Ascochyta Dianthi Lasche and Depazea Dianthi 
Desm. as synonyms of the latter species. 
Herpotrichia nigra.t— Dr. R. Raimann describes the injury in- 
flicted on Pinus Mughus by this parasitic fungus belonging to the 
Trichosphaeriaceee. The favourable condition for its luxuriant develop- 
ment is excessive moisture, as, for example, when the branches are laden 
with snow. Pinus excelsa , though growing in the immediate neighbour- 
hood, enjoys immunity from its attacks. 
New Entyloma.J — Under the name Entyloma Ellisii, Prof. B. D. 
Halsted describes a new species of this genus of parasitic fungi on the 
common spinach. It is the first species of Entyloma known to be 
parasitic on any plant belonging to the Chenopodiaceae, and the first on 
any cultivated plant in America. 
Hydnocystis.§ — Herr P. Magnus assigns reasons for placing this 
genus of Fungi among the Pezizeae, instead of among the Tuberaceae, to 
which it has hitherto been considered to belong. He regards the 
Tuberaceae as strictly cleistocarpous Ascomycetes, allied to the Peri- 
sporiaceae, and especially to Eurotium and Penicillium. 
New Parasitic Fungi. || — M. C. A. J. A. Oudemans describes the fol- 
lowing new Micromycetes : — Among Pyrenomycetes, — Opliiobolus Jaco - 
bsese on stems of Senecio Jacobsea ; among Discomycetes, — Phialea appen- 
diculata, on rotten stems of Mentha aquatica ; among Sphaeropsideae, — 
Sclerotiopsis Cheiri on rotten stems of Cheiranthus Cheiri, Ascochyta Solani 
on dry stems of Solanum tuberosum , Piggotia Gneti on leaves of Gnetum 
Gnemon ; among Hyphomycetes, — Botrytis longibrachiata on leaves of 
Curcuma rubricaulis , Clonostachys Gneti on leaves of Gnetum Gnemon , 
Cercospora Violse sylvaticse on leaves of V. sylvatica, Stilbum sanguineum 
on rotten leaves of Gnetum Gnemon, Fusarium Caricis on leaves of a 
species of Carex. 
Dr. C. Massalongo If gives descriptions of the following new species 
of parasitic fungi observed in the neighbourhood of Verona: — Cylindro- 
sporum Pimpinellee on Pimpinella nigra , Phyllosticta astragalicola on 
Astragalus glycyphylloides , Bamularia Ballotse on Ballota nigra, B. 
lamiicola on Lamium album, Stagonospora Iridis on Iris germanica. 
Dr. F. Cavara ** describes a new Macrosporium ( M . sarcinseforme ) 
which he found on red clover in the neighbourhood of Pavia. The 
parasite makes itself known by the presence of brown spots on the 
leaves.
