186 MORPHOLOGY AND TAXONOMY, FUNGI, ETC. [BoT. Absts., Vol. X, 



Entomogenous fungi destroy enormous numbers of scale insects and for this reason numerous 

 attempts have been made, notably in Florida, to control scale insect pests by means of these 

 fungi. After 30 years trial, however, "there is no instance of the successful control of any 

 insect by means of fungus parasites." [See also following entry.] — W. B. McDougall.

 insects. Trans. British Mycol. Soc. 7: 89-132. 1921. — This paper is to be continued in the 

 next part of the Transactions. The present installment includes a historical summary and an 

 account of the genus Microcera, of a new genus, Pseudomicrocera, and of the genus Sphaero-

 — The perfect stage of Rhacodiella castaneae proved to belong in the genus Sclerotinia and was 

 classified provisionally as aS. pseudotuberosa Rehm. A description is given. — F. M. Blodgett.

 "Californian bees" is one of several local names for the ginger-beer plant, which is made up 

 of 2 organisms, a yeast, Saccharomyces pyriforviis, and a bacterium. Bacterium vermiforme, 

 living together symbiotically. It is considered probable that both organisms are benefited 

 by the symbiosis, the bacterium obtaining metabolic substances given off by the yeast cells 

 and the yeast benefited by removal of these same substances. — W. B. McDougall.

 found on specimens of wood decomposed by Fomes officinalis. Attempts to germinate the 

 chlamydospores failed. — B. B. Higgins.

 1920. — Strains of Aspergillus have been found capable of growing at a maximum temperature 

 of 38°C. Two of these, Eurotiuvi Amstelodami and E. Chevalieri, were described as new species 

 by Mangin. Cultural studies have been made upon pathogenic forms of Aspergillus from 

 which the author concludes that the above mentioned species are but varieties of Eurotium 

 repens. He suggests the following names: Eurotium repens var. Amstelodami and E. repens 

 var. Chevalieri. — D. S. Welch.
