the usual size and presented no peculiarities aside from their novel 

 Situation. A brief review of the fungi which are known to occur in 

 similar locations is given. This mentions the „Ambrosia" fungus Poly- 

 poms volvatus which is said to occur only in the holes oi wood-boring 

 insects, Polyporus pinicola, and Ceratostomella pilifera. Three plates 

 illustrate the article. H. von Schrenk. 



Trelease, Wm.. AberrantVeilRemnants in some edible 

 Agarics. (Report Missouri Botanical Garden. XV. April 30, 

 1904. 83 pp. PI. 30—39.) 



Attention is called to some aberrant veil formations in Leplota 

 naucinus, a mushroom which is frequently found forming a loosely 

 attached collar around the stem, or as shreds on the margin of the 

 pileus. Care should be taken to distinguish this mushroom from Amanita 

 plialloides, which the latters volva ought to make easy. 



Similar aberrations are noted for Agaricus amygdalinus and.Hypho- 

 loma appendiculatum. On ten plates the above mentioned characters are 

 illustrated. von Schrenk.

Cummings, Clara E., The Lichens of Alaska. (Harriman 

 Alaska Expedition. V. Cryptogamic Botany. March 26, 1904. 

 p. 67—152. pl. 8—9.) 



This paper is based mainly upon the collections of lichens obtained 

 in Alaska by members of the Harriman Expedition in 1899, supple- 

 mented by several minor collections. The main collection comprised 

 more than 800 numbers, said to represent 217 species, 75 of which are 

 new the Alaska; the smaller collections yielded 9 additional new records, 

 making a total of 84 new to the region. 



An historical review of previous publications relating to the lichens 

 of Alaska and adjacent territory accompanies the list of species, together 

 with mention of species accredited to Alaska but not seen by the writer. 

 Keys to the species appear under each genus, but no generic diagnoses 

 are given. Two species, viz : Verrucaria fulva (pl. 8) and Pertusaria po- 

 cillaria (pl. 9) are described as new and the following new combinations 

 are proposed : Biicllia geographica conti gua (Schaer.), Biatora apochroeiza 

 (Nyl.), and Placodium fiiscoatriun (Bayrh.) Maxon.
