 d'OEx. [Contribution to the fungus flora of the Chateau-d'OEx region.] Bull. See. Vaudoise 

 Sci. Nat. 52: 395-418. 1919. — The author studied the fungus flora prevailing near Chateau 

 d'OEx during the latter part of the summer and the fall of 1918. It was found to be richer than 

 might have been expected from the meagre attention given to the region in floristic works 

 on Switzerland. An annotated list of the parasitic forms, including, however, only the 

 Peronosporaceae, Ustilaginaceae, Uredineae, Protomycetaceae, and the Erysiphaceae, is 

 given, supplementing a similar one previously issued by the author on the fungus flora in the 

 vicinity of Leysin, the 2 constituting an account of the parasitic fungi thriving in the Vaudoise 

 Alps. In the present list, the Uredineae, represented by 142 species, and the Erysiphaceae, 

 represented by 17 species, easily predominate, a fact partly attributable to the season of the 

 year during which the collections were made. Of the Peronosporales 10 species are mentioned, 

 and of the Ustilaginales 9 species. Protomyces macrosporus Unger, P. Kreuthensis Kiihn, 

 and P. Leucanthemi Magnus represent the Protomycetaceae. — Charles Drechsler.

 171-178. 1921. — Descriptions are given of 16 species of yellow Porias, including the following 

 new species: P. ochracea, P. flavida, P. Calkinsii, P. Parksii, P. subradiculosa, P.flavilu- 

 tea, and P. jalapensis. — H. R. Rosen. 



1530. Petch, T. Hypocreaceae Zeylanicae. Ann. Roy. Bot. Gard. Peradeniya 7: 85- 

 138. 1920. — This paper consists of 2 parts, the 1st consisting largely of critical notes on 

 Berkeley and Broome's types, the 2nd a systematic list. Eighty-one species in 2 genera are 

 enumerated from Ceylon. The following are described as new: Nectria discoidea, N . bomba, 

 N. albofulta, N . sulcispora, Bresadolella nigra, Hypocrea gigantea, H. brunnea, H. extensa, 

 H. chlorostroma, H. mellea, Hypomyces pallidus, Calonectria oodes, Gibberella rugosa, and 

 Micronectria eugeniae. — E. D. Merrill. 



1531. Pethybridge, Geo. H. Sexual organs of Phytophthora. Nature 107: 204. 1921. — 

 It was reported in Nature (93:226. 1914) that in P. ery</irosepfica and P. infestans the oogo- 

 nial incept penetrates the antheridium at an early stage, traverses it, emerges, and then swells 

 to form the oogonium proper. This type of sexuality occurs also in other species. One on 

 decaying apples has been found occasionally to show this phenomenon; also normal lateral 

 fusion of sex organs on the same individual. Occasional occurrence of the oogonial penetra- 

 tion should be looked for in species of the cactorum or omnivora group. Exchange of material 

 is desired by the author. — 0. A. Stevens.

 An account is presented of a little known ferment, some of its uses, and commerical possibili- 

 ties of growing it. — C. M. Sterling.

 fragariae,""Leptothyrixmimacrothecium,"and**Pezizaoenotherae." Mycologia 13: 135-170. 

 PI. 8-10, fig. 1-5. 1921. — The authors present "an account of the life-history, morphology 

 and taxonomy of a discomycete, Pezizella lythri (Desm.) Shear & Dodge, (comb, nov.) which 

 is found on a great variety of plants, and has three stages in its life-cycle : sporodochia, pycnid- 

 ia, and apothecia." The conidial stage belongs to the form genus Hainesia, the pycnidial 

 is Sclerotiopsis concava (Desm.) Shear & Dodge comb, nov., and the ascigerous stage belongs 

 to Pezizella. "Cross inoculation experiments show that the fungus is a weak parasite and 

 passes readily under favorable conditions from one host to another." About 50 hosts are 

 listed, including species of Acer, Ampelopsis, Castanea, Cercis, Cornus, Duchesnia, Epilob-
