bloods. Among 1,000 students at Ann Arbor, 

 I observed a few of each of the types of 

 Europe such as the Iberian, Northern, Alpine, 

 Celt, Littoral and Adriatic, but the majority 

 of the students observed vrere variable blends, 

 and the pure types were not exactly like the 

 prehistoric types of Europe from which they 

 were probably derived, although similar to 

 them in many ways. During the past year 

 my anthropometric investigations have in- 

 cluded the Filipinos of many provinces, but 

 especially the Igorots. Here as elsewhere pure 

 types are rare and blends are plentiful. Three 

 primary types (each represented by 8 or 9 in- 

 dividuals selected from 104 Igorots) are found 

 among the Igorots. None of these are pure, 

 however, but one type resembles the Negrito, 

 another resembles one of the prehistoric types 

 of Europe, while the third is unlike either of 

 the others, but not a blend of the two. The 

 majority of the Igorots represent a variable 

 blend, and they have been so long isolated that 

 a condition of no Mendelism has been reached. 

 There is conclusive evidence of the persist- 

 ence of type, yet the tendency to blend is em- 

 phatic.

A NEW EDIBLE SPECIES OF AMANITA 



DuRDSTG the autumn of 1908 I received speci- 

 mens and sketches of an interesting species of 

 Amanita which grows in the mountain forests 

 of California. The specimens were collected 

 and communicated by Mrs. Virginia Garland 

 Ballen, of Brookdale, Santa Cruz County, Cal. 

 The sketches were accompanied by careful 

 notes which Mrs. Ballen had made from her 

 studies and observations. While the plant 

 shows certain points of relationship to Ama- 

 nita cwsarea, especially to the robust Euro- 

 pean form, Mrs. Ballen had recognized that it 

 was different from the American form of A. 

 ccesarea, which is more slender, and in fact it 

 proves to differ in several ways from that 

 species. The plant is edible and often very 

 large, so that a single one is sufficient for a 

 meal. Pending a fuller illustrated account, 

 a brief description is given here. 



Amanita calyptroderma Atkinson and Bal- 

 len n. sp. Plants 10-15 cm. high, pileus 10- 

 22 cm. broad, stem 2-4 cm. stout. Pileus 

 maize yellow to chrome yellow; gills white, 

 then pale maize yellow to cream color ; annulus 

 and stem pale maize yellow to cream color. 

 Pileus stout, extreme margin striate, the cen- 

 tral and larger portion covered with the closely 

 adherent white calyptra of the volva; in age 

 of the larger plants this calyptra sometimes 

 cracking into areas. Gills adnexed. Spores 

 oval to elliptical, 8-12 X 7-8 fx. Annulus very 

 thin, membranaceous, superior, evanescent. 

 Stem hollow with loose cottony threads. Volva 

 white, thick, circumscissile, in dehiscence, the 

 upper portion remaining as a thick skin over 

 the central portion of the pileus; limb very 

 prominent, forming a broad cup- or saucer- 

 shaped structure from which the stem of old 

 plants often separates readily.
