238 SUMMARY OF CURRENT RESEARCHES RELATING TO 



Some New Species of Inocybe.— Geo. F. Atkinson (A^ner. Journ. 

 Bot, 1918, 5, 210-8). The author gives diagnoses of twenty-five 

 species of Inocijle new to science. They were all collected at various 

 dates during the last twenty years or so in Xew York State, mostly 

 at Ithaca or in the grounds of Cornell University. Atkinson pays 

 special attention to the cystidia as diagnostic characters. A. L. S. 



Novae Fungorum Species. XV.— H. and P. Sydow {Ann. Mijcoh, 

 1917, 15, 143-8). The fungi described in this contribution were sent 

 from many different regions, Japan, South Africa, etc. One new genus 

 is recorded, Actinomyxa ; the species A. australienses (Microthyriaceag) 

 was sent from Mr. Wilson in Australia, and grew on leaves of Lasio' 

 petahis. A. L. S. 



Notae Mycologicse. Series XXIII. — P. A. Saccardo (Atii Accad. 

 8ci. Venet.-Trent.-Istr., 1919, 10, 57-94). These notes deal with 

 Philippine fungi collected by C. F. Baker. The list comprises 149 fungi, 

 109 of which are new to science, the new species belonging largely 

 to Fungi Imperfecti. There are also four new genera : Reyesiella 

 (Uredine^), near to Ravenelia, but differing in the absence of sterile 

 cells, etc. ; Ferrarisia (Perisporiace^e) ; Tr otter ia (Sphserioideas) ; and 

 Syorostachys (Hyphomycetes). The species all come under the micro- 

 fungi group. A. L. S. 



Tympanopsis and some other Genera. — F. Theiszen {Ann. MycoL, 

 1917, 15, 269-77, 1 fig.). Under this title Theiszen gives the result of his 

 examination of a number of doubtfully placed species. He classifies 

 Tympanopsis among Coronophorese, a group very near Sorclarieee, and 

 adds a new genus, Euacanthe, with a setose perithecium, to the group. 

 Detailed descriptions of other genera and species are also given.

Mycological Contributions. — Fr. von Hohnel {Ber. Deutsch. Bot. 

 Ges., 1917, 35, 246-56) passes in review a considerable number of the 

 smaller fungi, indicating mistakes that have been made generally of 

 species placed in the wrong genera. He has established as new genera : 

 Discosphserhia, Apioportlie, Fezizellaster, Lacknastcr, Stereolachnea^ the 

 last three on account of hair formation on margin or disc. Also 

 CaJothyrieJla and HapJotheciella, the latter based on Dothedea Prostii. 

 Among Sph^ropsidese he descril)es Septochroa g.n. and Fhseophomopsis, 

 the latter based on FJioma Hederee. 



In a furtlier paper {Ann. MycoJ., 1917, 15, 293-;>03) von Hohnel 

 criticizes a great many genera and species. He himself adds as new 

 genera : Hypodermellina, with the associated RhahdostromeUina, Eiipro- 

 polella, Bifusella, and Eosphseria. A. L. S. 



Study of Fumagines.— F. W. Neger {Flora, 1917, X.F., 10, 

 67-lo9, 31 figs.). The term "fumagine" is given to those fungi that 

 live on the honey-dew of leaves. Such fungi are provided with a 

 mucilaginous mycelium to protect them against drought. Artificial 

 cultures were made of the fungi which are described. Numerous other
