diva Sydow, originally described from immature specimens, is here redescribed in ' ! « -t rt i 1 

 from a recent collection of well developed material. Sphaeria tosta Berk. >v Br. , Sphaerella 

 Fuckelii Pass., and Sphaeria tritorulosa Plowr. are found to be identical, and are 'I.

pycnidial Btage, Phyllosticta drymeia v. 11., is referred to the Sclerophomeae. '/" ario\ 

 macrosporellav. B. on dead twigs of Acer campesln isdcscrihi .v. A m-v, genus, Crypto- 



phacella v. II., is founded on ConiothyHum Heteropatellae v. II. This genus is referred to the 

 Selerophomeae, and is characterized by the absence of definite COnidiophores and by ♦ Ik; para- 

 sitic habit. The pyenidia occur inside the perithecia, apothecia, and pyenidia of other fungi. 

 Diplodiella Angelica* Diedicke is shown to have been founded on immature perithecia of 

 Leptosphaeria Doliolum (P.) parasitized by Didymosphaeria conoid <n Niessl and the species 

 is discarded. The original description of Metasphaeria Lonicerae Fautrey having been pre- 

 pared from poorly developed material, the species is here redescribed from a recent collection of 

 mature material. Byssothcriiim circinnans Fuckel is regarded as the ascigerous Btage of 

 Phoma roseola Desm. and the synonomy of the species is discussed. Leptosphar.ria Calami 

 Karsten, L. Acori K., L. acorella Cooke, and L. densa Bres. are shown to be identical, and 

 the binominal L. Calami Karsten being the oldest is retained for the species. Leplosplm 

 juncina (Auersw.) and L. juncicola Rehm. are regarded as closely related to L. Calami K. 

 and the three species are, according to Von Hohnel, probably in reality more properly referred 

 to the genus Scleropleella v. H. of the Pseudophaeriaceae. Asterosporium Hoffmai 

 Kunze is shown to be the conidial condition of Massaria macrospora (Desm.) Sacc. and the 

 new genus, Asteromassaria, is based on the species. Sphaeria hirta Fries is transferred to the 

 genus Karstenula, and is discussed as K. hirta (Fr.) v. H. The conidial stages of this and a re- 

 lated species, A', rhodostoma (A. & S.) Speg., are discussed and the synonomy given. A 

 new genus, Plagiostromella v. H., is founded on PI. pleurostoma v. H. on Sapidus sp. in 

 Japan. A detailed description of the species is given accompanied by text figures. The 

 genus is of doubtful position. The fruitbody is pluri-locular, has a definite ostiolum, and 

 bears its asci laterally. The species resembles a Phyllachora superficially but seems to be 

 nearer the Sphaeriaceae or the Clypeosphaeriaceae. It is suggested that the genus be made 

 the basis of a new family, the Plagiostromellaceae v. H. Sphaeria Scrophulariae Desm., 

 given by Saccardo as a species of Leptosphaeria, is here transferred to Pleospora and is called 

 PI. Scrophulariae (Desm.) v. H. Cucurbitaria Hendersoniae Fuckel incorrectly placed by 

 Saccardo in Melanomma is here transferred to Gibberidea as G. Hendersoniae (Fckl.) v. H. 

 Cucurbitaria protracta Fuckel and C. acerina Fuckel are shown to be identical and the first 

 name is retained. The synonomy of the conidial stage is discussed. Otthiella Aesculi v. H. 

 is described as new and the conidial stage is described under the name Pijrenochaeta Aesculi 

 v. H. The fungus is, however, stated to be possibly merely an immature Cucurbitaria. 

 Nitschkia Otth. 1869 is shown to equal 'Winterella Berl. 1894 and Winterina Sacc. 1899. A 

 new genus Apioporthe v. H. is founded on Diatrype anomala Pk., the species being cited as 

 Ap. anomala (Pk.) v. H. The genus is closely related to Diaporthe but differs in having a 

 Diatrype-like stroma sunken in the bark, with parallel perithecial necks, and with the cells 

 of the spore unequal. Sphaeria virgultorum Fr. is regarded as another species of Apioporthe 

 and is cited as Ap. virgultorum (Fr.) v. H. Melanconis tiliacea Ellis is transferred to the genus 

 Diaporthe. Calospora occulta Fuckel is transferred to Diapothe and cited as D. abnormis 

 v. H., the name D. occulta being preoccupied by D. occulta (Fuckel) X. Valsa sorbicola 

 Nitschke is shown to be a Diaporthe, and a detailed discussion of the various species of Dia- 

 porthe which occur in Central Europe on Prunus, Sorbus, Pirus and related genera is given. 

 Diaporthe dolosa Sacc, D. personata (C. & E.), D. oncostoma (Duby) Fuckel, and D. fasciiu- 

 lata Nitschke, all of which occur on Robinia Psexidoacacia, are shown to be one species and 

 the name D. oncostoma (Duby) Fuckel is retained for it. Moreover the pycnidial fungi, 

 Phomopsis oncostoma (Thiim) v. H. and P. pseudoacaciae (Sacc.) v. H. are shown to be the 

 same species, the former name being retained. Diaporthe leiphaemia (Fr.) and D. dryophila 

 Niessl are shown to be identical. Sphaeria apiculula Wallroth, described by Fuckel, is shown 

 to be a Gnomonia and is cited as G. apiculata (Wallroth-Fuckel) Winter. Diaporthe Spina
