300 MORPHOLOGY AND TAXONOMY, FUNGI, ETC. [Bot. Absts., Vol. VIII, 



a fungus identified as Fusicoccum Forsythiae Died., occurring on branches of Forsythia, 

 Syringa, Ligustrum., and Cornns is considered identical. A full synonymy is given but no 

 name is applied to the ascomycete form on account of its immaturity. Stigmatea moravica 

 Petrak is redescribed in detail from a recent collection of material showing unusually rich 

 development. It is shown that the fungus belongs in the Hypocreaceae, and Nectriella 

 moravica Petrak is proposed as a substitute name. A new genus, Cytoplacosphaeria, founded 

 on Placosphaeria rimosa Out., is proposed which differs from other genera of the Sphaeroi- 

 daceae in the relation of the pycnidia to the stroma. The author disagrees with von Hohnel 

 in considering this species the conidial stage of Scirrhia rimosa (Alb. & Schw.) Fckl.; it is 

 suggested that Diplodina arundinacea Sacc. may possibly be identical. Cytosporina Rubi 

 Died, is considered identical with Rhabdospora ramealis Desm. & Rob. and the new combina- 

 tion C7jtosporina ramealis (Desm. & Rob.) Petrak is proposed. A detailed description is 

 given of a Phomopsis which is considered to be the conidial form of Diaporthe Winteri Kunze 

 and the new combination Phomopsis Winteri (Kunze) Petrak is proposed. P. crataegicola 

 n. sp. occurring on dry twigs of Crataegus oxyacantha is described and thought to be a conidial 

 stage of Diaporthe Crataegi Fckl. The author distinguishes the latter from D. semiimmersa 

 Nke. A detailed description is given of Phoma chamaeropsis Cooke occurring on Chamaerops 

 humilis and the new combination Phomopsis chamaeropis (Cooke) Petrak is proposed. The 

 suggestion is made that Phyllosticta magnusii (Bomm. & Rouss.) Allesch. and P. cocoina 

 (Cooke) Allesch. var. Phoenicis (Brun.) Allesch. are substratum forms of the same species. 

 Pseudopleospora is proposed as a new genus of ascomycetes, with P. ruthenican. sp., on decor- 

 ticated stems of Eupatoritim cannabinum, as the type species; its relationships are uncertain, 

 it possibly belonging near the Hypodermataceae. The author suggests that it may represent 

 a distinct family. Peltosphaeria Petrakiana Rehm is redescribed and transferred to Dothiora; 

 Dothichiza fallox Sacc. is thought to be the conidial stage. Fusicoccum hranicense, on dry 

 twigs of Ulmus campestris, formerly confused with Phomopsis oblonga, is described as a new 

 species. Neokeissleria is proposed as a new genus, based on Ceriospora ribis P. Henn. & 

 Ploettner; a description with full synonymy is given. The relationship of this new genus with 

 Ceriospora and Melanconis is discussed in detail. Phomopsis phyllophila, on dry overwintered 

 leaves of Trifolium repens, is described as new. Phomopsis pyrrhocystis, on dry twigs of 

 Coryhis avellona, is also described as new and is thought to be the spermagonial form of 

 Diaporthe pyrrhocystis (Berk. & Br.) Fckl., with which it was found associated. Karstenula 

 ligustrina n. sp., on dry sprigs of Ligustrum vulgare, is described and thought to be the ascog- 

 enous stage of Microdiplodia mamma Allesch. Cucurhitaria moravica Rehm is transferred to 

 Karstenula; Microdiplodia Pruni Died, was found in association with it. Chaetocytostroma, 

 showing relationship with Fusicoccum, is proposed as a new genus based on an hitherto unde- 

 scribed species, C. arundinacea. The genus differs from Fusicoccum in the small spores and a 

 hairy stroma. A new genus of the Nectroidaceae, Blennoriopsis, is described, based on B. 

 moravica n. sp., on stems of Linaria genistifolia. Diaporthe abnormis v. H. is considered identi- 

 cal with D. occulta (Fckl.) Nke. (Calospora occulta Fckl.). The latter is made the basis of a 

 proposed new genus, Macrodiaporthe, which is stated to differ from Diaporthe in that the 

 stroma develops only above with the perithecia free below, the walls of the latter being thick 

 and leathery and the spores and asci very large. A full synonymy is given. The author agrees 

 with von Hohnel in considering Diaporthe oncostoma and D . fasciculata on Robinia identical, 

 and accepts his view that D. leiphaemia and D. dryophila on Quercus are the same; also that 

 D. Radula and D. oligocarpa are identical. But he does not agree that D. Crataegi and D. 

 semiimmersa are one species. D. brachyceras on Ligustrum, D. crassicollis on Cornus, D. simu- 

 lans on Rosa agree with forms on Pomaceae and Prunus investigated by von Hohnel. The 

 author does not agree with von Hohnel in separating the genus into Euporthe, Tetrastaga, 

 and Chlorostate, and thinks that this treatment only serves to complicate the situation. 

 Some general discussion of the genus is given and the importance of more culture work is 

 emphasized. Diaporthe Delogneana Sacc. & Roum. and D. helicis Niessl. are considered iden- 

 tical and a detailed description is given. A new genus, Phaeodiaporthe, based on P. Keiss- 

 leri n. sp. occurring on twigs of Aesculus hippocastamim, is described. It differs from 

 Diaporthe in the dark colored spores. — H. S. Jackson.
