Parasitic Fungi of New Jersey 167 



Earlea speciosa (Fries) Arth. — On leaves of cultivated roses. 



"O. Pycnia chiefly epiphyllous and caulicolous, crowded in con- 

 siderable groups, often confluent, inconspicuous, subcuticular, ex- 

 tending well into the lateral walls of the epidermal cells, pale honey- 

 yellow, flattened-conoidal or discoidal, 65-160 fx. in diameter by 

 35-50 mm. high. 



"I. Aecia hypophyllous and caulicolous, usually on swollen and 

 distorted areas of more or less extent, roundish, 0.5-1 mm. across, 

 on leaves forming small groups, on petioles, stems and fruit conflu- 

 ent into irregular groups 10 mm. or more long, applanate, bright 

 orange fading into pale yellow, ruptured epidermis usually conspicu- 

 ous ; paraphyses at first often rudimentary or wanting, in senile sori. 

 peripheral, usually few, erect, finally somewhat exceeding the height 

 of the spore mass, slender, clavate or cylindrical, 9-13 by 42-50 fi, 

 the wall almost evenly thin 1 fi or less, colorless ; aeciospores oblong- 

 elliptical, obovate, rarely oblong-clavate, 16-24 x 24-35 /*; wall pale- 

 yellow, rather thin, 1-2 fx, distinctly echinulate-verrucose with 

 pointed beads standing 1 fi apart, the pores indistinct, scattered. 



"III. Telia caulicolous, gregarious, crowded, oblong, about 1 mm. 

 long, usually more or less confluent and 10-30 mm. long causing a 

 somewhat fusiform hypertrophy, at first crust-like, with age becom- 

 ing felty, grayish-black; teliospores cylindrical, 21-27 by 58-102 fi, 

 rounded at both ends, except a semi-hyaline apiculus above 3-7 fi, 

 long and nearly as broad, 4-8 celled ; walls smoky-brown, 3-5 [x thick, 

 smooth, the pores 2 or sometimes 3 in each cell ; pedicel three to five 

 times length of spore, slightly tinted especially near the spore, 7-9 fi 

 in diameter, usually tapering in lower part, nearly or quite solid due 

 to thickened walls, somewhat rugose near base." North American 

 Flora, V. 7, p. 175 (1912). 



942. Teleutospore from cultivated rose, 1/12. 



KuEHNEOLA UREDiNis (Link) Arthur. — On species of Rubus sp. 



"O. Pycnia epiphyllous, in small crowded groups 0.3-0.5 mm. 

 across, on somewhat larger reddened spots, pustular, prominent, 

 fiattened-hemispherical, or irregularly lenticular, large, 150-200 fxin 

 diameter, nearly half as high. 



"II. Uredinia at first epiphyllous, surrounding the pycnia, in 

 crowded groups 0.5-1.3 mm. across, irregular in outline, 0.1-0.3 

 mm. across, in shortest diameter, usually somewhat elongate and of- 

 ten confluent into rings, at first bullate, soon naked and applanate, 

 pulverulent, orange-colored fading to whitish, ruptured epidermis 

 noticeable; uredinia afterward hypophyllous, scattered irregularly.
