2070. Skaife, S. H. Notes on some South African Entomophthoraceae. Trans. Roy. 

 Soc. South Africa 9: 77-86. PI. 2-4. 1921. — Records of South African Entomophthoraceae 

 published up to the present are confined to writings on the locust fungus, Empusa grylli. 

 In the present paper the occurrence of 6 species is recorded and notes have been made on their 

 morphology. These species are: Empusa muscae, E. conglomeraia, E. grylli, Entonwpldhora 

 aphidis, E. apiculata, and E. megasperma. — E. M. Doidge. 



2071. Stork, Harvey E. Biology, morphology and cytoplasmic structure of Aleurodiscus. 

 Amer. Jour. Bot. 7: 445-456. 3 pi. 1920. — Aleurodiscus amorphus grows on twigs and small 

 branches of fallen balsam fir. A small species of Tremella is often parasitic on the fruiting 

 bodies of this species, sometimes covering them entirely. The mycelium of Aleurodiscus 

 grows throughout the intercellular spaces of the bark parenchj'ma, originating as a mass of 

 densely woven hyphae in the deeper tissues, from which hyphae move upward, breaking 

 through the bark and producing the typical fruit body. In the cytoplasm are large filaments 

 and numerous granules, which are thought to be in a class with mitochondria, metachromatic 

 bodies, and other structures that have been described in the cytoplasm of fungi. — E. W^ 

 Sinnott. 



2072. Sydow, H., xfND P. [Sydow] Aufzahlung einiger in den Provinzen Kwangtung und 

 Kwangsi (Siid-China) gesammelter Pilze. [Enumeration of some fungi collected in the pro- 

 vinces of Kwangtung and Kwangsi, South China.] Ann. Mycol. 17: 140-143. 1919 [1920].— 

 Thirty two fungi of various groups, mostly parasitic species, collected by O. A. Reinking 

 in May and June, 1919, are listed. The following new species are described: Physopella 

 sinensis on Cudrania sp. ; Ustilago Apludae in spikes of Apluda mutica var. aristata; Euiypella 

 Paliuri on branches of Paliurus ramosissimus; Phtjllachora cantonensis on Litsea glutinosa; 

 Helmijithosporium Rhodomyrii on Rhodoinyrtum tomenlosa. A new genus of uncertain posi- 

 tion in the Fungi Imperfecti, Plenophysa, based on an hitherto undescribed species, P. mira- 

 hilis, occurring on leaves of Ficus e'astica and Zea mays, is described. — //. S. Jackson 



2073. Sydow, H., und P. [Sydow] Uber einige Uredineen mit quellbaren Membranen 

 und erhohter Keimporenzahl. [Concerning some Uredinales with gelatinous membrane and 

 more than the usual number of germpores.] Ann. Mycol. 17:101-107. 1919 [1920].— Seven 

 species of rusts of the Pucciniaceae having teliospores with a gelatinous outer wall and in 

 some cases more than 1 germ pore. The authors decide that Uredo cristata Speg., from Para- 

 guay on a Sapindaceous host, and U. Toddaliae Petch, from Ceylon on Toddalia aculeata, 

 are not uredo but telio forms, the teliospore wall in each consisting of 2 layers, the inner col- 

 ored and firm, the outer strongly echinulate and swelling considerably in water. For these 

 species they establish a new genus, Ctenoderma. The necessity for a division of the genera 

 Puccinia and Uromyces as now used is reviewed and the divisions proposed by Arthur and 

 Fischer are discussed. The authors give their ideas as to such divisions and propose 2 new 

 genera, Dichlamys and Trochodium, for species of Uromyces with gelatinous teliospore walls. 

 Dichlamys is founded on Uromyces Trollipi Kalchr. & McOwan, characterized by the apical 

 germ pore and striations or ribs on the teliospores. Trochodium is founded on Uromyces. 

 Ipomoeae (Thuem.) Berk, from South Africa and is characterized by apically grooved telio- 

 spores with radial ribs and a swollen pedicel. The genus Haplopyxis is proposed for Uropyxis- 

 like rusts having 1-celled teliospores; Uropyxis Crotolariae Arth. is the type. The possibility 

 of Uromyces dubiosus P. Henn. on Lantana from Brazil representing a new genus is discussed. 

 Puccinia Adesmiae P. Henn. on Adesmia trijuga from Argentine is transferred to the genus 

 Cleptomyces. — E. B. Mains. 



2074. Thaxter, Roland. Second note on certain peculiar fungus-parasites of living 

 insects. Bot. Gaz. 69: 1-27. 5 pi. 1920. — New genera and species are described in several 

 groups. Cantharosphaeria is a new genus of true ascomycetes, 1 species, C. chilensis, being 

 described; this may be saprophytic, but the species noted below are certainly parasites. 

 Termitaria is a new genus of the Fungi Imperfecti, perhaps referable to the Leptostromataceae, 

 but quite isolated in its characters; T. Snyderi and T. coronata are described. In Muiogone
