Gilkey, H. M., A revision ofthe Tuberales of California- 

 (Univ. California Publications Botany. VI. p. 275—365. pl. 26—30. 

 1916). 



A study based on the Harkness collection of hypogaeous fungi 

 at Leland Stanford Junior University, and the Universit}^ of Cali- 

 fornia collection, and of published descriptions and illustrations. All 

 Tubers thus far reported from California are „white" truffles 

 and do not have such marked odors as the highly prized „black" 

 truffles of Europe. The author concludes that the Tuberales are 

 linked to the Pezizales through the genus Hydnocystis. 



A key to the genera is given and one new genus, Hydnotryop- 

 sis, is described. The following new species and new combinations 

 appear: 



Hydnocystis Californica , Pseudobalsamea magnata [Balsamea 

 magnata Hk.), Genea Harknessii, G. Gardneri, G. intermedia, G. ce- 

 rehriformis {Myrmecocystis cerebriforniis Hk.), Hydnotrya ellipso- 

 spora, Tuber {Eutiiber) tevissiminn , T. {Ent.) separans, T. {Eut.) irra- 

 dians, T {Etit.) Gardnerii, T. {Eut.) argenteum, T. {Oögaster) lignariujn 

 [Terfesiopsis lignaria Hk.), Piersonia bispora, Geopora magnifica, 

 G. annulata, Hydnotryopsis Setchellii. W. B. McDougall. 



Farquhapson, C. O. and G. Lister. Notes on South Nigerian 

 Mycetosoa. (Journ. Bot. LIV. 64. p. 121 — 133. 1 pl. May 1916.) 



The first part of the paper, by Farquharson, is descriptive 

 of the topographical and climatic conditions ofthe districts in which 

 the collections were made. Feiled Oil-Palms afTorded a large num- 

 ber of species, some of which appeared to prefer certain positions, 

 as Physarella oblonga the dead female inflorescence, and P. reni- 

 forme the male. 



In the second part Miss Lister giv^es critical and descriptive 

 notes on the more interesting species. Two of these are new, na- 

 mely Physaruin digitatuvn, G Lister and Farquharson, and Dia- 

 chaea radiata, G. Lister and Petch; the latter had been previousl}'- 

 found in Ceylon. 



Miss Lister enumerates previous work on African Mycetozoa , 

 and adds a table showing all the species recorded from Africa 

 up to the present time, with their distribution elsewhere.

Berieht über die Tätigkeit der k. k. landwirtschaftlich- 

 chemischen Versuchsstation und der mit ihr verei-

 Pflanzenschutz-Station in Wien im Jahre 1 9 1 5. (Zeitschr,

Der Berichterstatter über die im Titel an letzter Stelle genann- 

 ten Station, K. Kornauth, erteilt genauen Bericht über die Studien 

 und Beobachtungen der Station. Wir melden hier nur folgendes: 

 Frühsorten von Weizen waren bis zu IOO^/q von Chlorops sp. befal- 

 len. Die Kirschblattwespe Eriocampsoides Umacina Retz befiel weni- 

 ger die Kirschen als die Birnen. Die Biologie des Springwurm- 

 wicklers der Rebe, Oenophtira pilleriana, konnte ergänzt werden
