usually arise symphyogenously, although they may arise by the compound mcrisiogenous 

 mode. Simple sporodochia usually originate by I lie simple meristogenoua met hod. ( 'omplex 

 sporodochia, with a large base or subicle, usually arise either by the compound meristogenoua 

 mode or symphyogenously. The pseudo-acervulus of i he species of P< talozzia b1 udied arises 

 and develops as a pyenidium which breaks open and appears like an acervulus. The Bimple 

 meristogenous development is the one more often found in the Sphaeropsidales, while the 

 compound meristogenous and aymphybgenous modes are the more usual in the Melanconiales 

 and Tuberculariaceae. — F. E. Kempton.

 mucors collected at the village of St. Peter, Switzerland.] Bull. Soc. Bot. Geneve 10: 362-376. 

 S fig. 1918. — Six cultures of Mucor which were obtained from the soil near St. Peter contained 

 two new varieties and two new species. Mucor Ramannianus Mocllcr was frequently found 

 in coniferous forests, sometimes on Sphagnum of peat bogs. M. plumbens Bonorden was com- 

 mon in the air and soil. M. hiemalis Wehmer ( — ) var. albus n. var produced occasional zygo- 

 spores with the -f- strain of the species. M. hiemalis (+) var. loundrae n. var. differs from 

 the species in its habit of growth in cultures. M. Jauchae n. sp. was isolated from the soil 

 of a fir forest. M. vallesiocus n. sp. was obtained from the soil, of a meadow. — W. H. Emig.

 Compt. Rend. Acad. Sci. Paris 170: 60-62. 1 fig. 1920.— C. fungorum is transferred 

 from the Mucedineae to the genus Amphisphaeria of the Ascomycetes. The author 

 has discovered and describes the asci-containing perithecia which appear in November be- 

 neath the dark-colored conidiferous filaments of this fungus when growing upon the white 

 fructifications of Corticium calceum Persoon or C. lacteum Fries as a host. These perithecia 

 develop until they project almost entirely free from the conidial layer, attaining a diameter 

 of 0.2 to 0.5 mm.— C. H. and W. K. Farr.

 10: 26-34. 1 fig. 1918. — Parmelia conspersa (Ehrh.) Ach. forma raga n. form occurs in abun- 

 dance on a certain plateau with all the vegetative characteristics of a steppe. On the steppe, 

 conditions for growth are unfavorable to the production of new lichen plants by the devel 

 ment of fungous spores and algal cells. As a consequence of the arid conditions this lichen 

 does not have fruiting bodies but multiplies by the fragmentation of the thallus. — W. H. Emig.
