200 NORTH AMERICAN FLORA [VoLuME 9 
DOUBTFUL AND EXTRALIMITAL SPECIES 
Lactaria acris (Bolt.) Fries, Epicr. Myc. 342. 1838. Reported from North Carolina 
by Schweinitz, but the specimens have been destroyed by insects and the determination 
cannot be verified. 
Lactarvia aeruginea (Lam.) Burl. Mem. Torrey Club 14: 46. 1908. Reported from 
Connecticut by White from Hanmer material, and from Minnesota by Johnson. The Con- 
necticut specimens proved to be Lactaria turpis (Weinm.) Fries; the Johnson specimens 
are not available for examination. 
Lactaria albida Peck, Ann. Rep. N. Y. State Mus. 38: 126. 1885. Further field work 
fs necessary before the identity of this form can be positively determined. 
Lactaria Calceolus Berk. I,ond. Jour. Bot. 6: 315. 1847. This species has not been 
reported since it was collected in Ohio by Mr. Lea, and the confluent pilei would indicate 
it to be an abnormal growth, very possibly of Lactaria hygrophoroides, described by 
Berkeley & Curtis in 1859 from Sprague material. 
Lactaria flexuosa Fries, Epicr. Myc. 338. 1838. Reported from North Carolina by 
Schweinitz, and from Vermont by Frost and Burlingham. The Frost and Schweinitz 
specimens are not preserved, and the third collection, upon subsequent comparison with 
European plants, proved to be uncertain forms. 
Lactaria illachrymans Berk. & Rav.; Berk. & Curt. Ann. Mag. Nat. Hist. IT. 12: 425, 
1853. This plant was collected in swamps in South Carolina by Ravenel, and has also been 
reported from North Carolina by Curtis. Since the coloration and zonation seem to indi- 
cate that the species is a Lactaria, it is probable that under favorable and normal condi- 
tions the context would prove to be lactiferous. Until further field study reveals more fully 
its characteristics I should hesitate to consider it a valid species. 
Lactaria mitissima Fries, Epicr. Myc. 345. 1838. Reported from Pennsylvania by 
Herbst, and from California by Harkness & Moore, but the specimens have not been pre- 
served. It is described in McIlvaine’s Am. Fungi 181. 1902. 
Lactaria pallida Pers. Tent. Disp. Fung. 64. 1797. Reported from Khode Island 
by Bennett, from Connecticut by White, and from Minnesota by Johnson. Only the 
Connecticut specimens are available for examination and they are pale forms of Lactaria 
lactiflua (\.) Burl. 
Lactaria pluinbea (Bull.) Fries, Epicr. Myc. 339. 1838. Reported from Wisconsin 
by Bundy and from New York by Peck. The Bundy specimens are not preserved, and the 
plant referred to this species by Peck is plainly some other form. 
Lactaria pubescens Fries, Epicr. Myc. 335. 1838. Reported from New Vork by Peck. 
Lactaria ‘‘ sacchavium’’ Johnson, Bull. Minn. Acad. Sci. 1878: 337. 1878. The 
specimens were collected under poplar trees, among moss “and grass. In view of the fact 
that the type specimens are not available, and that no further collections have been reported, 
it seems best not to recognize the species at present. 
Lactarta sanguinalis (Batsch) Schrét. Krypt. Fl. Schles. 3': 540, 1889. Reported 
from California by Harkness & Moore and described (Lactaria controversa Fries) in Mc- 
Ilvaine’s Am. Fungi 164. 1902. 
Lactaria subinsulsa Peck, Ann. Rep. N. Y. State Mus. 43: 65. 1890. The type 
specimens so closely resemble Lactaria affinis that it is probably a pale form of that species. 
Lactaria vieta Fries, Epicr. Myc. 344, 1838. Reported from Ohio by Morgan, but the 
specimens are not preserved. 
Lactaria zonaria (Lam.) Fries, Epicr. Myc. 336. 1838. Reported from Wermont 
by Frost, Rhode Island by Bennett, New Jersey by Ellis, Ohio by Morgan, Wisconsin by 
Bundy, Minnesota by Johnson, and from California by Harkness & Moore. The Ellis 
specimens, which are the only ones preserved, are not Lactaria Zonaria (Ellis & Ev. N. 
Am, Fungi II. 7976).
