DovuBTFUL SPECIES 
Mycena acicula (Schaeff.) Quél. Champ. Jura Vosg. 73. 1872. (Agaricus acicula Schaeff. 
Fung. Bavar. 4: Ind. 52. 1774.) Reported from many parts of North America and also 
from Cuba. No correctly determined specimens were found at Albany. The Cuban speci- 
mens at Kew are very tiny and difficult to compare. P. amabillissimus and P. pulcherrimus 
are probably the nearest relatives in this country. 
Mycena Adonts (Bull.) Quél. Champ. Jura Vosg. 68. 1872. (Agaricus Adonis Bull. 
Herb. Fr. pl. 560, f. 2; hyponym. 1793; Pers. Syn. Fung. 391. 1801.) Reported from the 
Carolinas by the older mycologists. Correctly determined specimens are not to be found at 
Albany. 
Mycena alcalina (Fries) Quél. Champ. Jura Vosg. 71. 1872. (Agaricus alcalinus Fries, 
Obs. Myc. 2: 153. 1818.) Reported from most of the eastern United States by American 
mycologists, but the plants have a different appearance and lack the strong alkaline odor found 
in fresh specimens collected in Sweden. P. capillaripes Peck has a weak alkaline odor but is 
quite distinct. See P. alcaliniformis. 
Mycena amicta (Fries) Quél. Champ. Jura Vosg. 223. 1872. (Agaricus amictus Fries, 
Obs. Myc. 1: 141. 1815.) Reported from North Carolina and California. 
Mycena californiensis (Berk. & Curt.) Sacc. Syll. Fung. 5: 255. 1887. (Agaricus (My- 
cena) californiensis Berk. & Curt. Proc. Am. Acad. 4: 112. 1858.) Described from specimens 
collected on dead oak leaves on Mare Island, California. The types at Paris are very poorly 
preserved. 
Mycena capillaris (Schum.) P. Karst. Bidr. Finl. Nat. Folk 32: 124. 1879. Reported 
by Ravenel, Ellis, and others. The species is described as very minute with a hair-like stipe, 
Mycena ctirinella (Pers.) Quél. Champ. Jura Vosg. 74. 1872. (Agaricus citrinellus Pers. 
Ie. Descr. Fung. 44. 1800.) Reported from many parts of North America by the older 
mycologists and also from Dominica by Miss A. lL. Smith. Plants at Albany from New 
Scotland so determined by Peck seem near P. epipterygius, but are much smaller than the 
usual form of that species. 
Mycena conferruminata (Berk. & Mont.) Sacc. Syll. Fung. 8: 258. 1887. (Agaricus 
(Mycena) conferruminatus Berk. & Mont. Syll. Crypt. 110. 1856.) Collected on soil mixed 
with decayed wood near Columbus, Ohio. ‘The surface is described as purplish-yellow and the 
lamellae as white. 
Mycena debilis (Fries) Quél. Champ. Jura Vosg. 72. 1872. (A garicus debilis Fries, 
Epicr. Myc. 112. 1838.) Reported from North Elba by Peck. 
Mycena discreta (Fries) Sacc. Syll. Fung. 5: 260. 1887. (Agaricus discretus Fries, 
Elench. Fung. 20. 1828.) Described from specimens collected on the Island of Santa Cruz 
by Benzon.
