120 THE VICTORIAN NATURALIST. 



Puccinia investita, Schwein., Syn. N. Am. Fungi, No. 2,932 ; 

 Peck, 25, Rep., p. 117 ; Sacc, Syll., vii., p. 707. 



Sori plentifully scattered on stems and leaves ; on latter 

 amphigenous, but more numerous on under surface, bursting 

 through epidermis and woolly tomentum, bordered by ruptured 

 cuticle, circular or oval in outline or on stem lenticular, under 

 1 mm. in diameter. Spermogones immersed among spores in 

 sori, numerous, subglobose with conical apiculus, walls dark from 

 blackish network on outer surface ; spermatia tinged brownish, 

 fusiform. Uredospores greatly predominating in the sori, which 

 are mostly reddish-brown in colour, subglobose, deep brown, 

 sparsely verruculose, largest 23-24//. x 20-24//. Teleutospores 

 few and generally mixed with uredospores, dark chestnut brown 

 with almost black outline, distal cell somewhat the larger and 

 obtusely pointed by thickened epispore or rounded, with a slight 

 external constriction between the two cells ; largest 30-40//. x 

 20-23//. Unicellular teleutospores not infrequent, 26//. x 18-20/1. 



On leaves and stems of Gnaphalium purpureum, L., Oakleigh, 

 January. 



Evidently the same species as that named above, and infesting 

 various members of the genus Gnaphalium in North America, 

 where, however, only the teleutospores have been found. uEcidium 

 gnaphaliatum, Schwein., is found on a North American species of 

 the same genus, while Uredo gnaphalii, Speg., on G. Americanum, 

 has been described from Argentina. 



Puccinia rumicis-scutati (D. C), Winter, Pilze, i., 187; 

 Sacc, Syll., vii., p. 636, var. Muhlenbeckiae ; Cooke, Grevillea, 

 xix., 46, Handb., p. 336. 



Uredospore sori hypophyllous, scattered, minute (under irara.), 

 on discoloured circular spots, which are sometimes confluent 

 and accompanied by corresponding spots on upper surface, on 

 which also are occasionally opposite sori ; epidermis bullate, 

 at length ruptured, exposing the flat pale-brown spore bed ; 

 uredospores pale yellowish brown, ovate, obovate or oblong, 

 echinulate, largest 25-30//. x 16-20/z. 



On green and fading leaves of Miihleubeckia adpressa, Meissn., 

 Brighton, May. 



Teleutospores only of this variety described by Cooke, but not 

 observed in this specimen. The uredospores, it will be seen, 

 correspond pretty closely with the characters given for the 

 European specimens, except as regards the size of the spores — a 

 point, however, of limited significance. 



Errata. — The title of article in Victorian Naturalist, xi., page 90, 

 should read as above. Page 90, line 20, for " accidiospores " read 

 "cecidiospores." Page 90, line 36, for " primrose " read "pruinose."
