558 AUSTRALIAN FUNGI, 



52. PUCCINIA CALENDUL.E, II. sp. 



i. Aecidia orange-yellow, in clusters, crowded, sometimes 

 circinate, 320-360 fi diam.; pseudoperidia with margin torn and 

 reflexed; peridial cells quadrate or polygonal, striated at margin, 

 21-24 iJL long. Aecidiospores very irregular, subglobose to poly- 

 gonal, very finely echinulate, pale orange, 14-17 x 11-12 /x. 



iii. Teleutosori intermixed with aecidia, black, erumpent, soon 

 naked, girt by the ruptured epidermis, circular to elliptical, 

 compact, often confluent. Teleutospores yellowish-brown, clavate, 

 constricted at septum, thickened at apex, rounded or acute, 

 epispore smooth, 36-52 x 19-23 /x; upper cell darker in colour and 

 broader than lower, 21-31 /x long, and sometimes thickened to a 

 depth of 12 /Li; lower cell slightly or not at all tapering towards 

 pedicel, and averaging same length as upper; pedicel hyaline, 

 persistent, 28-37 x 7-8 /x, may attain a breadth of 10 ^ at junction 

 with spore. 



X. Mesospores not uncommon, similarly coloured to teleuto- 

 spores, elliptical to pear-shaped, thickened at apex, 30-42 x 21-23/x. 



Armadale, Victoria; 1892, 1902 and 1903 (Robinson) on 

 upper and under surface of leaves and all green parts, including 

 fruits, of Calendula oj/icinalis, L.; Killara, Oct., 1902. 



Aecidium-stage all the year round, but less common in mid- 

 summer. Teleuto-stage from March to June. The aecidium-stage 

 was the only one found at first, and was described in the Agri- 

 cultural Gazette of New South Wales, 1896, p. 152. Then in 

 March, 1902, the teleuto-stage was found by Mr. G. H. Robinson, 

 and was very plentiful this season. It causes swelling, distortion, 

 and discoloration of the flower-stems and leaves, and the bright 

 orange colour of the aecidia on the leaves readily attracts atten- 

 tion from its harmonising with the flower-head. 



53. Puccini A flavescens, n.sp. 



ii. Uredosori on upper surface of leaf, minute, linear, often 

 confluent, soon naked, pulverulent, rusty brown, arranged along 

 furrows of leaf. Uredospores globose to shortly elliptical, finely
