be a mixed species. The variety Malvarum upon the leaves of Malva sylvestris and M. rotundi- 

 folia is taken as the type; it is identical with Ascochyta destructiva (Desm.) v. H. upon Malva 

 and should bear the latter name. The variety 6 Lycii should be known as Ascochyta Lycii 

 (Desm.) v. H. A new genus, Stictopatella v. H., is based on Phyllosticta destructiva var. c 

 Evonymi Desm. The type species is Stictopatella Evonymi (Desm.) v. H. The various species 

 of Phyllosticta described upon Hedera are the same. Apiosporium Fumago Fuckel is called 

 Diplopeltis Fumago (Fckl.) v. H. Peltaster Hedyotidis Sydow is said not to be related to Erio- 

 ihyrium duhiosum Speg.; it is a conidial stage of one of the Coccodiniaceae. E. fuegianum 

 Speg. belongs to the Pycnothyriaceae. An amended description is given for the genus Astero- 

 viella Pass, et Thiim. Sacidium alpestre Cesati is said to be hardly distinguishable from 

 Leptothyrium vulgare (F.) but is called L. alpestre (Ces.) v. H. The conidial stage of Eurya- 

 chora betulina (Fr.) Schroter is a member of a new genus of the Leptostomaceae, here named 

 and described as Didymochora v. H. The genus Dothiorella Sacc. is a composite genus; many 

 transfers to other genera are made and discussed. A description of the new genus Sclerothy- 

 rium V. H. is given followed by the complete synonymy. The type is S. Tamarisci (Mont.) 

 V. H. Sphaeropsis conglobata Sacc. is said to be a typical Hendersonula Speg. and therefore 

 must be called H. conglobata (Sacc.) v. H. It is probably the conidial stage of Dothidea 

 virgultorum (Fr.) Wint. Sphaeria oreades Fries is merely a differently developed leaf-inhabit- 

 ing form of Dichomera Saubinetii (Mont.) Cooke, as a variety of which it is named oreades 

 (Fr.) v. H. The characterization of the genus Dichomera Cooke-Sacc. is amended and a new 

 genus, Pseudodichoraera v. H., is erected for Dichomera varia (Pers. ?) Diedicke, which is 

 doubtless the conidial stage of Cucurbitaria bicolor Fuckel. Dichomera Elaeagni Karsten is 

 given as Pseudodichomera Elaeagni (K.) v. H. ; Camarosporium Elaeagni Potebnia is identical, 

 Dichomera Laburni Cooke et Massee and the different species of Camarosporium which have 

 been described on Cytisus are placed in Pseudodichomera. Dichomera Tiliae (Therry) Sacc, 

 D. sphaerosperma (B. et C.) Sacc, and D. stromatica (Preuss.) Sacc. are genuine Dichomeras. 

 Dichomera mutabilis Berk, et Broome is perhaps Cucurbitaria Platani Tavel. Dichomera 

 midabilis is a Pseudodichomera. On 1 specimen of Dichomera mutabilis occurred an unde- 

 scribed Botryodiplodia which v. Hohnel names B. corylicola. The genus Pseudostegia Bubdk is 

 based upon P. nubilosa (Ell. et Ev.) Bubdk, which is identical with Cryptosporium atrum 

 Kunze. Cryptosporium Kunze and Cryptosporium Sacc. are, notwithstanding the fact that 

 they both possess hyaline conidia, different from one another. C. atrum Kze. is closely related 

 to Pilidium Kunze (not Sacc.) and Harposporella v. H. An amended description of Crypto- 

 sporium, Kunze (not Sacc) is given. The genus Placosphaeria Sacc. (not deNotaris) is 

 discussed. It is understood to contain only the characteristic forms of the conidial stage of 

 typical species of Euryachora Fuckel; 12 species are critically considered. Coniothyrium 

 concentricum (Desm.) Sacc. is given as Dothisphaeropsis concentrica (D.) v.H. Coniothyrium 

 Agaves (Mont.) Sacc. is very similarly constructed and a comparison of the 2 fungi must show 

 whether it is a question of form of growth of the same fungus due to external stimuli or whether 

 it is a different fungus. Readeriella 7nirabilis Sydow may be related to Dothisphaeropsis. 

 Phoma jasminicolum Desmazieres is shown to be a Stictochorella v.H., and is called S. jasmini- 

 cola (Desm.) v. H. Stictochorella Juniperi v. H. n. sp. is probably a conidial stage of a species 

 of Carlia (Phyllachoraceae). The genus Leptostromella Sacc. was erected by Saccardo and 

 Roumeguere as a section of Leptostroma. It contained to a certain extent Leptostroma with 

 elongate conidia. However, the 2 genera are entirely distinct. The type species, Leptostro- 

 mella septorioides Sacc, is the conidial stage of a Phyllachora. Linochora v. H., erected for 

 the conidial stages of Phyllachora with thread-shaped conidia, is dift'erent from Leptostromella 

 Sacc. Leptothyrium Cytisi Fuckel is shown to be Leptostromella Cytisi (Fuck.) v. H. ; Lepto- 

 stromella Atriplicis Bubdk et Krieger is similar. Septoria caricinella Sacc. et Roumeguere is 

 a Linochora and is called L. caricinella (Sacc. et Roumg.) v. H., and is assumed to be the coni- 

 dial stage of Phyllachora caricis. Diplodina samaricola Diedicke is said to have been incor- 

 rectly and incompletely described by Diedicke; it represents a separate form genus, which von 

 Hohnel calls Septochora. Diplodina samaricola Diedicke should therefore be called Septo- 

 chora samaricola (Died.) v. H. Peltistromella brasiliensis v. H. is said to be closely related 

 to Phragmopeltis (P. H.) v. H. and Peliistroma (P. H.) v. H. but has 2-celled conidia. Septoria
