worthy species of the same group. He describes two species of Hypo- 

 nectria, and a new Nectria semenicola which grew on partially decayed 

 seeds. . 



Hyphomycetes.* — Lindau concludes the discussion of the genus 

 ffarpographium, begun in the previous fascicle, and distinguished from 

 Graphium by the sickle-shaped conidia. Other genera of Tuberculiuiese 

 are dealt with in two recently-issued parts including Tubercularia, Spha- 

 celia, etc. The Setosa group, represented by Volutella and Periola, 

 are also partly described. There are many illustrations in the text, 

 though the genera are not all accompanied by drawings. 



Uredineae. — W. Tranzschelf records the results of a series of culture 

 experiments : Puccinia Epilobii was found to be identical with P. 

 Veratri ; the teleutospores of P. Sonchi produced pycnidia, and, later, 

 uredospores ; teleutospores of P. Allii were sown on Allium paniadatum, 

 and only uredospores were developed. Several new hosts were dis- 

 covered for P. Isiacse. 



M. Raciborski J describes a considerable number of new species from 

 Java, belonging to such different genera as Jola, Uromyces, Uromy- 

 cladium, Gerwasia g. n., Puccinia, Sphserophragmium, Endophyllum, 

 Skierha, Hamaspora, JEcidium, Caeoma, and Uredo. 



L. H. Pammel § has studied the different forms of Gymno sporangium 

 that are to be found in Iowa. One of the most troublesome and 

 destructive species is the cedar apple, G. macropus, which grows on 

 red cedar, the Roestelia stage occurring on cultivated apples and doing 

 great damage. He recommends the removal of cedar trees. 



Rene Probst || has made a series of cultures with Puccinia Hieracii 

 within the genus Hieracium. He claims to have isolated thirteen 

 biological species. He determined two different species from the 

 position of the germinating pore, Puccinia Hieracii and P. pilo- 

 selloidarum, these species being again split up into a number of bio- 

 logical form species. Details are given of the different cultures, and 

 the occurrence of these two species with their biological forms is dis- 

 cussed. 



T. Yestergren If received from British Columbia an JEcidium on 

 Habenaria gracilis, and found it to be identical with 2E. alascanum 

 collected on several species of Habenaria in Alaska. It differed in 

 several particulars from JE. orchidearum. 



H. Yamada and J. Miyake ** describe a new species of Gymno- 

 sporangium on Ghamsecyparis pisifera. By culture experiments they 

 proved its affinity with the JEciditim on Pirus Miyabei and P. Aria var. 

 Puimaonensis .
