Exsiccati: TTrocystis Ilypoxis Tliaxt., on Ilypoxis erecta, Ell. & Ev. 
N. A. Fungi, 2688. 
Soii in the flowers more or less distorting and destroying the 
inner parts, often extending down on pedicles and peduncles for a 
short distance, somewhat irregular oblong, about 1-2 cm. in length, 
upon rupture of protecting parts disclosing purple black dusty spore 
mass; spore balls chiefly ovoid to spherical, 25-60 p in length ; 
sterile cells reddish yellow, completely covering the spores, ovoid, 
about 9—14 p in length ; spores reddish brown, polyhedral to sub- 
spherical or spherical, occasionally ovoid to oblong, 1-8, chiefly 3-5 
in a ball, usually 13-16 p in length. 
Host: Hypoxys erecta , Conn, (type), Mass. 
This smut was originally described from West Rock Park, New 
Haven, and has been found in North America in only one other 
locality, near boston. It has, however, been found in South Amer¬ 
ica. 1 haxter reported its germination.

lype. Entyloma Ungerianum DeBy. 1 {Protornyces microsporus Ung.) 
Host: Ranunculus repens. Germ. 
Son usually in the leaves, generally forming discolored but little 
distorted areas .permanently imbedded in the tissues ; spores simple, 
produced terminally or intercalary in the fertile mycelium which 
does not entirely disappear through gelatinization, free (sometimes 
irregularly adhering through pressure), hyaline to yellowish or red¬ 
dish yellow , occasionally dark colored, of medium size; germination 
by a short promycelium bearing a terminal group of sporidia which 
usually conjugate in pairs and produce secondary sporidia or infec¬ 
tion threads; conidia often present, formed by germination of the 
spores in situ or on the mycelium protruding through the stomata, 
hyaline, usually elongated. 
1 This is now known as Entyloma microsporum (Ung.) Schrot. DeBary did 
not use this specific name because he said it was inappropriate.
