A Contribution to a Revision of the North American 
Hydnaceae forms Vol. 12 of the Memoirs of the Torrey Bo¬ 
tanical Club, issued 13 June 1906, author Howard James Banker. 
The area covered includes the continent of North America and 
its adjacent Islands north of the Isthmus of Panama. Of the 
500 known species not more than 200 have been found in our 
region. Dr. Banker’s synopsis of genera shows, the following 
names: Hydnum, Hericium, Steccherinum, Echinodontium, 
Sarcodon, Hydnellum, Phellodon, Leaia, Auriscalpium, Grandini- 
odes. The monograph contains full descriptions, ample notes 
and keys. The new species here proposed are as follows: 
Hericium fimbriatum, Steccherinum morgani, St. adustulum, Sar¬ 
codon reticulatus, Sarcodon underwoodii, Hydnellum nuttallii, 
Hydnellum complicatum, Hydnellum earlianum, Phellodon ellisi- 
anus and Leaia piperata. Two new genera are Leaia (Hydnum 
stratosum Berkeley, 1845), an d Grandinioides (Hydnum flavum 
[Swartz 1835] Berkeley 1843). This important monograph also 
includes a Bibliography of 11 pages. 
A lengthy list of parasitic fungi collected near Triberg 
in August 1905 is given by Otto Jaap in the Botanische Zeit- 
schrift, No. 7-8, August 1906, under the title Ein Kleiner Beitrag 
zur Pilzflora des Schwartzwaldes. He regards as of especial in¬ 
terest the following: Dothidella geranii, auf Geranium silvati- 
cum, Melampsorella blechni, Puccinia chrysosplenii, auf chryso- 
splenium oppositifolium, Phoma sagittalis n. sp. auf Cytisus 
sagittalis, Actinomena podograriae, Ramularia prenanthis n. sp., 
Cercosporella magnusiana auf Geranium silvaticum, und Passa- 
lora bacilligera var. alnobetulae n. var. auf Alnus alnobetula. 
A list of about 3 dozen species and description of Poly- 
porus fagicola n. sp. is given by William A. Murrill in the Febru¬ 
ary No. of Torreya (1906). The collections were made in Au¬ 
gust and September 1905. The new species was found on the 
top of a fallen decorticated beech log in heavy mixed woods on the 
slope of Boarstone Mountains, Piscataquis Co., Maine. It has 
the habit of Polyporus polyporus. 
A STUDY OF THE DEVELOPMENT OF ASCUS AND SPORE FORMS 
in Ascomycetes by J. Horace Faull is published in the Proceed¬ 
ings of the Boston Society of Natural History, vol. 32, No. 4, 
June 1905. No full report can here be given, but the eleventh 
item in this summary is as follows: The evidence points to the 
conclusion that while the ascus has probably not been derived 
from the sporangium of the Mucorineae, the phenomena of spore 
formation are not incompatible with the view that homologizes
