3. Tolyposporella (?) Nolinae Clinton, Proc. Best. Soc. Nat. 



Hist. 31 : 426. 1904. 



Sori on the leaves, usually so crowded as to form a continuous and very conspicuous 

 stratum of agglutinated black granular spores over the greater part of their surface ; spore- 

 balls rather indefinite, often apparently of two, three, or four spores adhering in various ways 

 and often separating into single spores ; spores olive-black, oblong or ovoid to spherical, 

 flattened where in contact, with thick smooth epispore, chiefly 11-18 fJ- in length. 



On Dracaenaceae : 



Nolina microcarpa, Arizona, 

 Type locality : Rincon Mountains, Arizona, on Nolina inicrocarpa. 

 Distribution : Known only from the type locality. 



10. TOLYPOSPORIUM Woronin, Abh. Senck. Nat. Ges. 12 : 577. 1882. 



Sori usually in the inflorescence, more especially in the ovaries, forming a granular 

 spore-mass at maturity ; spore-balls dark-colored, composed of numerous spores perma- 

 nently united, of medium size ; spores bound together by ridged folds or thickenings of their 

 outer walls, of small to medium size ; germination about as in Ustilago. 



Type, Sorosporiufn /unci Schrot. 



Sori 2-5 mm. in length ; spores polygonal or irregularly subspherical. 



Sori occupying only an occasional ovary. 1. T. bullalum. 



Sori usually occupying all of the ovaries. 2. T. globuligerum . 



Sori 1-2 mm. in length ; spores uniformly subspherical. 3. T. EriocatiH. 



1. Tolyposporium buUatum Schrot. Krypt. Fl. Schles. 3': 276. 1887. 



Sorosporium bullatum Schrot. Abh. Schles. Ges. Abth. Nat. Med. 1869-72 : 6. 1870. 



Sori in ovaries, infecting occasional ones, ovate, about 3-5 mm. in length, covered with a 

 thin greenish smooth membrane, upon rupture of which the black granular spore-mass be- 

 comes scattered; spore-balls black, opaque, oblong to spherical or polyhedral, usually con- 

 taining 100 or more firmly agglutinated spores, chiefly 50-180 ^ in length; spores semihya- 

 line to light reddish-brown, covered with a thin tinted outer coat, more or less folded in 

 ridges by which the spores are bound together and which on rupture of -^spore-balls often 

 show as spiny projections at spore-margin, usually ovoid to subspherical or polyhedral, 

 chiefly 7-10 /^, or rarely 12 /i, in length. 



On Poaceae : 



Echinochloa Crus-galli {Panicum Crus-galH), Connecticut, Illinois, Iowa, Massachusetts, 

 Nebraska, North Carolina. 

 Type locality: Silesia, on Panicum Crus-galli {Echinochloa Crus-galli). 

 Distribution : New England to North Carolina and Nebraska ; also in Kurope.

2. Tolyposporium globuligerum (Berk. & Br.) Ricker, Jour. 



Myc. 11: 112. 1905. 



Thecaphora globuligera Berk. & Br. Trans. Linn. Soc. II. 1 : 407. 1879. 



Testicularia Leersiae Cornu, Ann. Sci. Nat. VI. 15 : 21^, 1883. (Type from Algeria, on Leersia 



hexandra.') 

 Ustilago Leersiae Dur.; Cornu, Ann. Sci. Nat. VI. 15 : 274, as a synonym. 1883. 



Sori in ovaries, apparently infecting most of those in the inflorescence, more or less 

 hidden by the enveloping glumes, oblong to occasionally subglobose, about 2 or 3 mm. in 

 length, covered by a rather thick smooth membrane that upon rupture discloses the black 

 granular spore-mass ; spore-balls opaque, composed of many spores, variable, chiefly ovoid
