fungus mentioned. The host plants are arranged according to the Engler system. Volume 

 1 includes all hosts belonging to the lower groups of plants up to and including the Monoco- 

 tyledons, volumes 2, 3, and 4 will embrace the dicotyledons, and volume 5 will serve as an 

 alphabetical register for the 4 preceding volumes. The fungi are arranged by families under 

 the name of the host, the families of each of the primary subdivisions of the fungi being 

 grouped together. The organs of the host on which the fungus occurs are also indicated. Only 

 the flora of Europe is covered but the term "European plant" is used in its broadest sense, 

 any plant found in the living state in Europe, whether wild or cultivated, native or introduced^ 

 being included. Although the author died in 1906 the work has been completed up to 1910 

 by collaborators, and the whole is published under the direction of the Hollandsche Maat- 

 schappij van Wetenschappen of Haarlem. The work represents an attempt to meet a need 

 long-felt by mycologists for a host-index, a need hitherto very imperfectly supplied by volume 

 13 and succeeding volumes of Saccardo's Sylloge Fungorum.— ff . M. Fitzpatrick.

 eration of fungi.] Vol.2. xix + I069p. MartinusNijhoff: The Hague, 1920.— The 2nd volume 

 of the publication discussed in the preceding entry. This volume contains hosts belonging

2069. Petrak, F. Mycologische Notizen. [Mycological notes.] Ann. Mycol. 17: 59-100. 

 1919 [1920].— Phomopsis pustulata Sacc. is transferred to Sclerophoiyia; a detailed description 

 is given, also a comparison with Sclerotiopsis protracta (Sacc.) Died, and Myxofusicoccum 

 obtusulum (Sacc. & Br.) Died. A Cytospora stage of Valsella polyspora Nke. is described 

 which is considered identical with Cytospora personaia Fr. Evidence is presented to show that 

 Valsella polyspora and V. adhaerens Fckl. are probably merely many-spored forms of Valsa 

 Auersu-aldii Nke. Dothidella ribesia (Pers.) Theiss. and Syd. is transferred to Phragmodothella 

 and a full synonymy given, with which the American species P. Kelseyi (Ellis & Ev.) Theiss. 

 & Syd. (Homostegia Kelseyi Ellis & Ev.) is questionably included. Phomopsis juglandina 

 (Fckl.) V. H. is described in full together with a Fusicoccum-like form which is considered an 

 abnormal type of the Phomopsis. Septoria Meliloti (Lasch.) Sacc. (Sphaeria Meliloti Lasch.), 

 Ascochyta caulicola Laubert, Siagonospora carpathica Baum., and S. Medicaginis (Desm. 

 & Rob.) V. H. are all considered to be identical with S. compta (Sacc.) Died., and the. new 

 combination S. Meliloti (Lasch.) Petrak is proposed and full synonymy given. A detailed 

 description is given of a form of Phomopsis ribesia (Sacc.) Died, which is stated to be the 

 spermagonial form of Diaporthe purgens Nke. The latter is considered merely a form of D. 

 strumella (Ft.) Fckl. An Otthia on Ligustrum is described which is considered identical with 

 Otthia Crataegi Fckl. ; Diplodia ligustrina West was collected in association with it but it is 

 not thought to be the conidial stage since 2 species of Didymosphaeria were also found either 

 of which might be the ascogenous stage of the Diplodia. Phleospora Hrubyana Sacc. on 

 ^SpzVaeac/iaTOaedn/oZia is described and considered identical with AS'ep<ormOTaffnws2ar!aAllesch. 

 In this connection the relationship and limitations of the genera Phleospora, Septoria, Cylin- 

 drosporiuvi, and Septogloeum are discussed and the following new combinations proposed: 

 Phleospora platanoides (Allesch.) Petrak {Septoria seminalis Sacc. var. platanoides Allesch.), 

 P. heraclei (Lib.) Petrak (Ascochyta her aclei Lib.), P. padi (Karst.) Petrak {Cylindrosporium 

 padi Karst.), P. magnusiana (Allesch.) Petrak {Septoria magnusiana Allesch.). The con- 

 clusion is reached that Diaporthe spiculosa (Alb. & Schw.) Nke. and D. circumscripta Otth. 

 occurring on Sambucus spp. are identical, being merely growth forms of the same species. 

 Likewise the 2 conidial forms assigned to these species, Phoma sambucella and P. sambucina, 

 are the same and should be cited as Phomopsis sambucina (Sacc.) Trev. A new genus, Keiss- 

 lerina, regarded as closely related to Dothiora, is founded on a hitherto undescribed species, 

 K. moravica, occurring on dry twigs of Evonymus europaea; Dothichizaevonymi Buh. & Kab. 

 is the conidial stage. An immature ascomycete, presumably a species of Botryosphaeria, 

 is described which is considered to be the probable ascogenous stage of Botryodiplodia Fraxini 

 (Lib.) Sacc, with which it was associated and of which a full description is given. Dothiorella 

 Fraxini (Lib.) Sacc. is thought to be merely a young development of the same species; likewise
