No. 3, October, 1921] MORPHOLOGY AND TAXONOMY OF FUNGI, ETC. 247 



far as known all species of Diplodina are coniflial stages of Didymella, and as a member of this 

 ascomycetous genus is sparsely present in the type-specimen the fungus is called Didymella 

 Leguminis-Cytisi v. H. Botryelln nitidula Sydow is a Darluca parasitic on a Puccinia. The 

 Pxiccinia is a new species and is named P. aculeaiispora v. H. Sphaeria perforans Roberge 

 should be known as Tiarospora perforans (Roberge) v. H. This fungus is always accom- 

 panied by Leplosphneria sabnletorum (Berk, et Br.) v. IT. and is probably its conidial stage; 

 the complete synonymy is given. Haplosporella longipes Ellis et Barth. is said to be a typical 

 Sphaeropsis [S. longipes (E. et B.) v. H.]; it is perhaps only aiorm oi Sphaeropsis Mori Berlese. 

 Pleosphaeropsis Dalbergiae Diedicke, type of the genus, is shown to be merely a strongly 

 erumpent Sphaeropsis which has a tendency toward multi-chambering and fusion of some 

 pycnidia with each other; Pleosphaeropsis is dropped. Coniothyrium olivaceum Bon. 

 var. Pini-silvestris Ferraris 1002 is treated as Aposphaeriopsis Pini-silvestris (Ferraris) v. H. 

 Coniothyrium Cedri Rolland is possibly identical with it. The genus Haplosporella Speg. 

 is a mixture of very different, unrelated forms. The type, //. chlorostroma Speg., is the same 

 as Camarosporium Rohiniae (West) Sacc, differing only in that for the most part the septation 

 of the conidia has not occurred. C. Rohiniae (West) Sacc, C. fenestratum (B. & C.) Sacc, 

 and C. Pseudoacaciae Brun. are said to be identical. Haplosporella Brunaudiana Passerini 

 is over-mature Anthostomella Scopariae H. Fabre. The old perithecia are used as hosts by an 

 Eriospora, for which E. biparasitica v. H. is suggested. Haplosporella caespitosa (B. et Br.) 

 Sacc. is perhaps a conidial form of Cucurbitaria Hederae Winter. Haplosporella dothideoides 

 Sacc. is an over-mature member of the Phyllachoraceae, Phaeochora Chamaeropsis (Cooke) 

 V. H. Haplosporella minor Ell. and Bartholomew is probably the conidial form of an unknown 

 Cururbitula, and Sclerothyrium minor (Ell. and B.) v. H. is suggested as its name. Haplo- 

 sporella missouriensis Bubdk is considered a Dothiorella with colored conidia. Haplosporella 

 Rhamni Diedicke is called Sclerothyrium Rhamni (D.) v. H. Coniothyrium insitivum Sacc 

 is said to be a mixed species and in part is referred to a species of Sclerothyrium. Haplosporella 

 dendritica Raciborski is probably a Lasmenia with a well-developed stromatic tissue. Cer- 

 tain species of Haplosporella are said to have demonstrable conidiophores; a new genus, 

 Microsporella, is created for these. M. pityophila v. H. is the conidial stage of Cuctirbitaria 

 pityophila (K. and S.) de Not. Stenocarpella Zeae Sydow should be called either Macrodi- 

 plodia macrospora (Earle) v. H. or Diplodia Zeae (Schw.) L^v. var. macrospora (Earle) v. 

 H. Ten different forms of Septoria described on the leaves of species of Convolvulus are 

 discussed. They are said to represent but 2 different species, Septoria ConvolvuU Desm. and 

 Hendersonia Calystegiae (Westendorp) v. H.; a complete synonymy is given. Taeniophora 

 acerina Karsten is transferred to the Sphaerioideae-astomae from the Excipulaceae. Sphae- 

 ronaemella Karsten was based on a Ceratostomella-like ascomycete. Sphaeria vitrea Corda 

 is made the basis of a new genus of the Nectrioidaceae called Hyalopycnis ; some related 

 species of Hyalopycnis are perhaps conidial stages of Hypomyces. The new genus Mycorhyn- 

 chella (Nectrioideae) is described. It differs from Mycorhynchus Sacc. in the micro-plecten- 

 chymatous structure of the pycnidia and in the conidia. A new genus, Cyanophomella v. 

 H. (Nectrioideae-ostiolatae) is based on Phoma acervalis Sacc Botryogene Sydow is identi- 

 cal with Stagonostroma Diedicke and Botryogene visci Sydow becomes Stagonostroma visci 

 (Syd.) V. H. It is considered a pycnidial stage of a Gibberella. The nomenclatorial tangle 

 existing in connection with the generic names Chaetostroma and Amerosporium is discussed 

 and several new binomials are proposed. Chaetodiscula hysteriformis Bubd,k et Kabdt is 

 identical with Myrothecium typhae Fuckel, and Chaetodiscula Bub. et Kab. is identical with 

 Myxormia Berk, et Br. The genera Dinemasporixim L6v., Pseudolachnea Ranojevic, and 

 Dinetnasporiopsis Bub. et Kab. are identical. A new genus, Bactrexcipula, is created and 

 referred to the Patelloidaceae-Excipulatae. The synonymy of Psalidosperma mirabile Sydow 

 is given. It probably represents a new genus, Eriosporella v. H., of the Melanconiaceae. The 

 description of Hainesia Ellis et Sacc. is amplified. Dacryomyces Lythri Desmazieres is a 

 Hainesia and is called H. Lythri (Desm.) v. H. //. Iremellina Sacc. is a typical Hainesia. 

 H. Rubi (Westendorp) Sacc. is not a Hainesia and is provisionally designated as Leptosporium 

 Rubi (West.) v. H. Hainesia Feurichii Bubdk probably belongs to Pseudopeziza. Hainesia 

 taphrinoides D. Sacc. et Cavarais to be cancelled. Phyllosticta destructiva Desm. is said to
