ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 237 



Genus Clavariopsis Holt. — X. Patouillard {Bull. Soc. Mijcol. 

 France, 1920, 36, 61-3, 2 figs.). The genus was established by Holter- 

 mann to induclc species of Tremella with a Clavaria form of growth. 

 Three species from tropical countries have been determined as belonging 

 to the genus. Patouillard now describes a fourth from the Philippines 

 collected by Professor Otto Reinking. This species is distinguished by 

 the formation of new basidia arising from a continuation of the fertile 

 filament from the base of that previously formed. A section shows a 

 whole series of these basidia in tiers up to the exterior of the plant. 

 The fungus grows in groups of upright simple or branched stalks up to 

 2 cm. high. A. L. S. 



Higher Basidiomycetes from the Philippines and their Hosts. 

 I.— 0. A. PtEiXKiXG {Pliilippine Joum. Sci., 1919, 15, 479-90). The 

 list includes the larger fungi that grow on living or dead trees. The 

 former being parasitic are more restricted in their hosts. Schizophyllum 

 commune, a saprophyte, is recorded on fifteen different woods. The 

 fungi were identified by X. Patouillard. A list of hosts is also given 

 with their parasites. A. L. S. 



Cytology of Eocronartium muscicola. — Harry M. Fitzpatrick 

 {Amer. Joum. But, 1918, 5, 397-419, 3 pis.). A detailed study of the 

 cytology of the fungus in all its stages. All the hyphse seem to have 

 binucleate cells. The nuclei fuse in the young basidia. The various 

 phases of nuclear division are described. Nothing is known of the 

 nuclear history which follows spore germination and precedes the 

 appearance of the binucleated series of cells in the hyphse. The fungus 

 is closely related to the Uredinales, and there may be a cell fusion at 

 one stage which would provide the two nuclei. A. L. S. 



Hymenomycetes of France. — H. Bourdot and A. Galzix {Bull. 

 Soc. Mycol. France, 1920, 36, 43-7). An account of species of 

 Asterostroma and Asterodon. The Asterostromea^ form a small group 

 characterized by the stellate cystidia analogous with the cystidia of 

 Hymenochsete, etc. Three species of Asterostroma are recorded for 

 France, and one of Asterodon. They are all more or less brightly 

 yellow in colour. A. L. S. 



Polyporacese of Bengal. III. — S. R. Bose {Bull. Med. Coll. Belgachia, 

 1920, 1-8, 6 pis.). The writer gives good popular descriptions of 

 twelve species of more or less common occurrence. The paper forms 

 part of a series by the same author. A. L. S. 



Development of some Exogenous Species of Agarics. — Gertrude 

 E. Douglas {Amer. Joum. Bot., 1918, 5, 36-54, 7 pis.). A study of 

 development in Mycena suhalccdina, Hygrophorus sp., and Entoloma sp. 

 In these Agarics the fruit-body is at first a button of interwoven 

 hyphae. Differentiation arises by apical growth, and the hymenophore 

 originates in the annular furrow which is at the junction of stem and 

 pileus. Gills develop as in endogenous forms, except that they are 

 exposed from the beginning. A. L. S.
