No. 3, October, 1921] MORPHOLOGY AND TAXONOMY OF FUNGI, ETC. 249 



macrospora Durieu et Montagne is shown to be closely related to Kellermannia anomala 

 (Cooke) V. H., but is an independent genus which probably should be called Piptarthron 

 Montagne. An amended description is given to the genus Piptarlhron ^lontagne. Ischnos- 

 troma Merrillii Sydow is shown to be a conidial stage of a member of the Polystomellaceae, 

 almost certainly an Asterodothis and not the conidial stage of a member of the Trichopeltaceae 

 as previously stated. Sirosphaera hotryosa Sj'dow is placed among the Pachystromaceae- 

 Dothideales-Superficiales where it is supposed to be the conidial stage of a member of the 

 Dothideaceae. On the type specimen of Phoma Ilicis DesmaziSres were found 2 fungi, Phyllo- 

 sticta ilicicola C. et Ell., and Phoma Ilicis, which is a Phomopsis and is called P. Ilicis (D.) 

 V. H. Phoma lirella Desmazieres is a Phomopsis, P. lirella (D.) v. H., and on the same stem 

 occurs the related Diaporthe (Euporthe) Vincae Cooke. Phoma subnervisequum, Desmazieres 

 is a typical Phomopsis which must be called P. subnervisequia (Desm.) v. H. Since Diaporthe 

 Laschii Nitschke occurs on Evonymus, Phomopsis subnervisequia probably belongs to it. 

 Phoma effusum Roberge must be called Phomopsis effusa (Rob.) v. H., and it is probably 

 the conidial stage of Diaporthe (Tetrastaga) Therryana P. et S. Phoma Hellebori Br. et 

 Har. 1891 is said to be the same fungus. Only Diaporthe Phoenicis Pat. and D. Chamaeropina 

 Gaja have been known upon palm leaves. A number of forms described on them as Phoma 

 and Phyllosticta are certainly species of Phomopsis. Thus Phoma cocoina Cooke, P. palmicola 

 Winter, P. Phoenicis Sacc, P. Phoenicis (Ces.) Sacc, and P. coccophila Speg. will probably 

 all be reduced to 2 species. Phomopsis syngenesia (Brun.) v. H. is said to be the conidial stage 

 of Diaporthe syngenesia (Fries). It is also stated that Phoma syngenesia P. Brunaud and P. 

 Frangulae Oudemans are identical with Phomopsis syngenesia (Brun.) v. H. Pyrenochaetinia 

 obtegens Sydow shows no bristles; it may for the present be placed in Sclerophomina v. H. 

 Sphaeria Miribelii Fries should be known as Sarcophoma Miribelii (Fries) v. H.: the complete 

 synonymy is given. This fungus is probably the conidial stage of Naevia pallida (Fuck.) 

 Rehm. Phoma nitidum Roberge in herb, is transferred to the genus Sclerophoma as S. nitida 

 (Rob.) v. H., although not a tj^pical species. Sphaeria aliena Fries is S. foveolaris Fries 

 1823; a complete synonymy is given [see also Hedwigia 59: 270. 1917]. Phoma punctiformis 

 Desmazieres is referred to the genus Sclerophoma as S. punctiformis (Desm.) v. H. Baker- 

 ophoma Sacchari Diedicke, type of the genus, is shown to be worthless and the genus is 

 cancelled. — E. E. Honey. 



1.52.5. Johnstone, Jas. Fungoid infection of plaice. Proc. and Trans. Liverpool Biol. 

 Soc. 34: 120-121. Fig. 1-2. 1920. — Two plaice that had died in the spawning pond were 

 found to have their liver, spleen, kidneys, and peritoneum containing small whitish nodules 

 1-2 mm. in diameter. The nodules were found to consist of a fungus body, composed of mj'cel- 

 ium and sporangium-like bodies. — Charles Drechsler. 



1526. IvAUFFMAX, C. H. Isoachlya, a new genus of the Saprolegniaceae. Amer. Jour. 

 Bot. 8:231-237. 2 pi. 1921. — This new genus is established to include 3 species: I. toruloides, 

 a new species here described under the joint authorship of Kauffmax and Coker; I. paradoia 

 (Coker) comb, nov., and 7. monilifera (de Bary) comb. nov. These are all characterized by 

 the presence of the cymose Achyla mode of formation of secondary sporangia, coupled with 

 diplanetic zoospores. /. toruloides was studied in detail and the morphological and physiologi- 

 cal differences resulting from cultivation on various substrata are recorded. — E. W. Sinnott. 



1527. Marchal, El., etEm. [Marchal]. Contribution a I'etude des champignons fructi- 

 coles de Belgique. [Contribution to the study of the fruit-inhabiting fungi of Belgium.] 

 Bull. Soc. Roy. Bot. Belgique 54: 109-139. 1921.— The author identifies 67 species, of which24 

 are species or varieties new to science. The investigations have been carried out for G years 

 on fleshy fruits, especially on the stone-fruits. Frequent resort to pure cultures from mycel- 

 ium was made. Besides forms already known, descriptions of the following new species are 

 given: Pleospora Lycopersici, Diaporthe perniciosa, Dotkiorella vinosa, D. Mali Karst. var. 

 globuligera, Fuckelia conspicua, F. Malorum Oud. var. macrosporium, F. rimosum, Cytosporella 

 fructorum, Hendersonia vagans Fuck. var. fructicola, Oospora umbrina, Hyalopus pruiJiosus,
