 Hah. Torquay. Parasitica] on Dictyota dichotoma. Annual. 

 Summer. 

 This minute and microscopically beautiful little plant 

 -covered some years ago by Mrs. Griffiths on the 

 old fronds of Dictt/ota dichotoma, and first described in the 

 first edition of the ' Manual of British Algae.' I ha 

 seen any other specimens than those originally collected by 

 Mrs. Griffiths, who met with the parasite infesting several 

 specimens of the Dictyota ; nor am I aware that any other 

 observer has noticed it in Britain, or that it has been de- 

 tected elsewhere. The Alga on which it grows is bo very 

 widely scattered that our Elachista ought, probably, to 

 have a place in many distant Floras, hut its minute si/e lias 

 hitherto been its protection. It looks so much like the 

 fructification of the Dictyota, when carelessly examined 

 with the naked eye, or with a lens of small power, thai it 

 may often he passed over as such ; and I w as once disposed 



to think that it might he merely a diseased proliferous state 



of thai fructification. This opinion 1 have long abandoned, 



and recognized this production as a true parasite.
