92 MORPHOLOGY AND TAXONOMY OF FUNGI, ETC. [Bot. Abstb., Vol. V, 



tative cells, occurring in the blood of infected insects, are ontogenetically related to other 

 phases in the development of the organism. Fruiting structures of the Isaria type have been 

 observed in culture and in moist chamber. An ascigerous stage has not been observed. An 

 emended description is presented. — -The organism produces a disease of noctuid larvae (cut 

 worms) and in infection experiments a mortality of from 60 to 90 per cent was obtained. — 

 Ingestion of vegetative cells by phagocytes was observed, the process being followed appar- 

 ently by the destruction of the phagocytes. Phagocytosis is discussed at some length, also 

 certain phases of insect control by means of fungous parasites. — A bibliography of 24 titles is 

 appended. — D. Reddick. 



685. Stevens, F. L. Three new fungi from Porto Rico. Mycologia 12: 52-53. 1920.— 

 The following fungi collected by the writer and briefly described by Mr. Lamkey are presented: 

 Microstoma ingaicola Lamkey sp. nov. producing witches' brooms on Inga laurina, M. pithe- 

 colobii Lamkey sp. nov. producing spots on Pithecolobium saman, and Perenoplasmopara 

 portoricensis Lamkey sp. nov. producing spots on Melia azedarach. — //. R. Rosen. 



686. Stevens, F. L., and Nora Dalbey. A parasite of the tree fern (Cyathea). Bot. 

 Gaz. 68:222-225. 2 pi. Sept., 1919. — A fungus collected on Cyathea arborea in Porto Rico has 

 characters suggesting relationship with Microthyriaceae, Perisporiaceae, Dothidiaceae, and 

 Phacidiaceae; the authors incline to place it in the last-named group, proposing for it a new 

 generic name, Griggsia. The type species is described as Griggsia cyathea. — H. C. Cowles.

 1917. [7th addition to the fungus flora of Sonntagberg.] Verhandl. Zool.-Bot. Gesell. Wien. 

 68: 97-123. 1918. — A list of species is given accompanied by the data of collection and criti- 

 cal notes. The material was in most cases examined by von Hohnel and a considerable number 

 of species and a few genera are listed as new and are attributed to him. Some of these have 

 been published elsewhere by von Hohnel but others are designated here as unpublished, the 

 binomial being followed by the citation "v. H. nov. spec, in litt." These fall in many groups 

 of the fungi but since technical descriptions of these will be given elsewhere by von Hohnel 

 they need not be listed here. — H. M. Fitzpatrick. 



688. Takahashi, R. On the fungous flora of the soil. Ann. Phytopath. Soc. Japan 

 l 2 : 17-22. 1919. — The author isolated several fungi from the soil of the test garden of the 

 Tokyo Imperial Agricultural College by using soil extract gelatin-agar (+60, Fuller's scale). 

 The isolation is made at two different periods, the one in September, 1915, and the other in 

 February, 1916. The result of the experiments is listed as follows: In 1915 (a) In the soil 

 obtained from 2 cm. below the surface: Mucor racemosus, Aspergillus oryzae, A. fumigatus, 

 Penicillium roseum, P. candidum, P. sp. No. 1., Chaetomium crispatum, Stemphylium verru- 

 culosum, and Penicillium sp. No. 2.; (b) 5 cm. below the surface: Aspergillus fumigatus, A. 

 niger, Penicillium humicola, P. candidum, Allescheriella nigra, Acrostalagmus sp., and Hel- 

 minthosporium subulatum; (c) 8 cm. below the surface: Aspergillus fumigatus and Trichoderma 

 Koningi; (d) 12 cm. below the surface: Penicillium Duclauxi, Penicillium sp. No. 2, Chaeto- 

 mium alivaceum and Alternaria tenuis. In 1916 (f) 2 cm. below the surface: Rhizopus nigri- 

 cans, Aspergillus oryzae, A. niger, A. glaucus and A. nidulans; (g) S cm. below the surface: 

 Mucor adventitus, M. circinelloides, Zygorhynchus Molleri, Rhizopus ?vigricans and Botrylis 

 cinerea. — T. Matsumoto. 



689. Tanaka, Ty6zabur6. New Japanese fungi-notes and translations — VIII. Myco- 

 logia 12: 25-32. 1920. — The following fungi are described: Phytophthora Carica (Hora) 

 Hori causing a fruit rot of Ficus Carica, Capnodium Tanakae Shirai and Hora sp. nov. sapro- 

 phytic on fruits of Citrus grandis, Gloeosporium foliicolum Nishidasp. nov. causing a spotting 

 of fruits and leaves and a blighting of twigs of Citrus spp., Dactylaria Panici-paludosi Sawada 

 sp. nov. on living leaves of Panicum paludosnm, Dactylaria Leersiae Sawada sp. nov. on 

 living leaves of Leersia hexandra and Dactylaria Cosli Sawada sp. nov. on living leaves of 

 Costus speciosus. — //. R. Rosen.
