Teleutospores. A 



Fig. 130. P. Hydrocotyles. 



Teleutospore and 



uredospore. 



very few are found in the uredo-sori, 



ellipsoid to oblong, rounded at both 

 ends, hardly thickened above, gently 

 constricted, smooth, brown, 30 — 44 x 18 



-N/z : pedicels hyaline, I liin. deciduous. 



On Hydrocotyle vulgaris. Rare : 

 Kew Gardens; Epping Forest; Ireland, 

 Co. Dublin. Uredospores, July — Sep- 

 tember; teleutospores, October. (Fig. 

 130.) 



This species is very imperfectly known. 

 The secidiun) is recorded only from South 

 America ; in Europe the uredo-form alone has 

 been observed, except for a few teleutospores 

 in the uredo-sori. Lindroth describes the 

 teleutospores (which are rare everywhere) as furnished with large isolated 

 depressed and rounded warts, while those I have seen are perfectly 

 smooth and with long and persistent pedicels. Cooke describes both 

 uredo- and smooth teleutospores, intermixed, on Hydrocotyle, from Natal 

 (Grevillea I.e.). Sydow states that the uredospores from all localities 

 agree perfectly ; those that I have examined from the Hawaian Islands 

 agree exactly with ours, having the same peculiar colour resembling a 

 strong wash of ''raw sienna." 



This species illustrates, in the Epping Forest locality, what can be 

 frequently observed : — that, so long as the surroundings are undisturbed 

 by man, many species of Fungi occur year after year continuously in the 

 same spot. It is recorded as found there in 1863, 1864, 1871, 1882, and 

 1906, etc., and no doubt could have been found, or was found, there equally 

 in all the intervening years. 



Distribution : France, Holland, Italy, North and South 

 America, Natal, Pacific Islands.
