200 Aecidium Amarantaceae, Hyp eric aceae. 



AMARANTACEAE. 



Deeringia. 



142. Aecidium deeringiae Cooke and Mass. 



Cooke and Massee, Ann. Rep. Dept. Agr. Queensland, p. 40 

 (1893). 



0. Spermogonia on discoloured spots on the upper surface. 



1. Aecidia crowded on orbicular pallid spots (2-3 mm.) on the under 



surface, which are somewhat thickened, semi-immersed, margin 

 white, crenulate. 



Aecidiospores sub-globose, very finely echinulate, 12 ^ diam. 



On living leaves of Deeringia relosioides R. Br. 



Queensland Gladfield (Gwyther), (Bailey. 12 ) 



The colour of the spores could not be determined in the dried specimens. 



Only the name of this fungus was given in the Annual Report, and Dr. 

 Cooke has kindly furnished me with the description in MS. 



Uromyces deeringiae Syd. occurs on Deeringia indica in Java and the 

 Philippine Islands, but the aecidiospores are 22-28 ^ diam., so that they 

 are quite distinct from the present form unless there has been a mistake in 

 the transcription of the size of the spores. The host in both cases is the 

 same according to the Index Kewensis.

HYPERICACEAE. 



Hypericum. 



143. Aecidium disseminatum Berk. 



Berkeley in Hook. Handb. Fl. N.Z., p. 756 (1867). 

 Sacc. Syll. IX., p. 322 (1891). 



I. Aecidia on under surface of leaves, causing corresponding eleva- 

 tions on upper surface, sub-gregarious or crowded, sometimes 

 confluent, fully ^ mm. diam. ; pseudoperidia raised, with white 

 margin, reflexed, fimbriate; peridial cells sub-quadrate, average 

 30 x 22 fi. 



Aecidiospores orange-yellow, sub-ellipsoid to sub- angular, 

 finely verrucose, 16-17 x 11-13 p.. 



On Hypericum japonicum Thunb. 



Victoria Murramurrangbong Ranges, Nov. 1902, and Dec., 1903 

 (Robinson). 



The original description by Berkeley is very brief : " Spots none or effused. 

 Peridia scattered, short ; margin lobed ; spores white." Since it was 

 hardly possible from this description to be certain of the species, a specimen 

 was sent to the Royal Gardens, Kew, for comparison with the type specimen 

 there, and it was found to be identical. 



This aecidium occurs on the same host-plant as Melampsora hypericorum 

 (DC.) Schroet. and is occasionally found on the same leaf with the uredosori.
