115. Micropuccinia Symphoricarpi (Hark.) Arthur & Jackson. 
Puccinia Symphoricarpi Hark. Bull. Calif. Acad. 1: 35. 1884. 
Dicaeoma Symphoricarpi Kuntze, Rev. Gen. 33: 470. 1898. 
O. Pycnia unknown. 
III. Telia amphigenous, chiefly hypophyllous, closely gregarious and more or less con- 
fluent on yellowish spots 0.4-0.8 cm. across, often causing some hypertrophy, roundish, 
0.4-1 mm. across, tardily naked, compact, pulvinate, blackish-brown, long covered by the 
cinereous epidermis; teliospores ellipsoid, oblong, or oblong-clavate, often somewhat irregular, 
18-24 by 34-56 yu, rounded or obtuse above, rounded, truncate, or narrowed to the pedicel 
below, slightly constricted at septum; wall cinnamon-brown, 1.5-3 » thick, thickened above, 
7-13 », somewhat thickened over pore of lower cell at septum, smooth; pedicel firm, tinted, 
equaling spore or shorter; mesospores occasionally intermixed. 
This species is correlated with Dicaeoma abundans (Peck) Arth. & Fromme, the telial 
characters of the two species being similar or identical, and the hosts of the short-cycled 
form corresponding with the aecial hosts of the heteroecious form. This agreement doubtless 
indicates a common origin for the two species.

116. Micropuccinia Apocyni (Dietel & Holway) Arthur & Jackson. 
Puccinia Apocyni Dietel & Holway; Holway, Bot. Gaz. 24: 33. 1897. 
O. Pycnia unknown. 
III. Telia hypophylious, numerous, gregarious and crowded in groups 3-8 mm. across, 
on yellowish spots, roundish, small, 0.2-0.4 mm. in diameter, early naked, compact, pulvinate 
cinnamon-brown becoming cinereous by germination, ruptured epidermis not noticeable; 
teliospores cylindric or clavate-cylindric, 16-19 by 36-48 y, obtuse or acute above, rounded 
or more commonly narrowed to pedicel below, strongly constricted at septum; wall golden- 
brown, 1-1.5 « thick, thickened above, 8-12 u, smooth; pedicel fragile, colorless, short. 
On CAPRIFOLIACEAE! 
Lonicera pilosa H.B.K., Mexico (state). 
TYPE Locality: Eslava, near City of Mexico, on ‘“‘Apocynum androsaemifolium,” error for 
Lonicera pilosa. 
DISTRIBUTION: Vicinity of the type locality. 
117. Micropuccinia Adoxae (Hedw. f.) Arth. & Jackson; Arth. 
Bull. Torrey Club 48: 40. 1921. 
Puccinia Adoxae Hedw. f.; DC. Fl. Fr. 2: 220. 1805. 
Dicaeoma Adoxae S. F. Gray, Nat. Arr. Brit. Pl. 1: 543. 1821. 
Dasyspora Adoxae Arth. Résult. Sci. Congr. Bot. Vienne 346. 1906. 
O. Pycnia unknown. 
III. Telia amphigenous, from a perennial mycelium, gregarious in groups of various 
size, often scattered on swollen petioles and stems, round, 0.5 mm. across, early naked, pul- 
verulent, chestnut-brown, ruptured epidermis somewhat noticeable; teliospores ellipsoid or 
oblong, 15-20 by 24-38», rounded or somewhat obtuse above with a prominent hyaline 
umbo covering the pore, rounded, obtuse, or narrowed below, scarcely constricted at septum; 
wall cinnamon-brown, moderately thin, 1.5-2 4, slightly thickened above, 3-5 yu, smooth; 
pedicel colorless, fragile, about length of spore, ustially deciduous. 
This species is correlated with Dicaeoma Nolitangeris (Corda) Arth., the telia of the 
two species having the same morphological characters, and the host of the " short- cycled form 
being the same as that of the aecia of the heteroecious form. This agreement doubtless 
indicates a common origin.
