THE CLASSIFICATION OF THE TILOPTERIDACE^. 177 



closely resembles the genus Ectocarpiis in vegetative 

 structure. Kiitzing,^ later, taking certain anatomical de- 

 tails into consideration, renamed the plant Tilopteris 

 Mertensii, leaving it, however, among the Ectocarpacese. 

 Thuret^ next removed it from that family on account of 

 its possessing large immobile spores, and created the 

 order Tilopteridacese (" Tilopteridese ") to receive it. 



Kjellman,^ in 1871, added the new genus Ilaplospora, 

 and later, in 1875,* the genus Scapliospora. 



For an interesting historical account the reader is referred 

 to Reinke's^ important paper on the family, the above 

 beiDg the merest outline, and only in so far as it affects 

 the classification. 



Although TiloiDteris Mertensii Klitz. was first found, and 

 recognised as a distinct species, in Britain, the types of 

 Kjellman's two additional genera were overlooked in this 

 country until recently, when first, in 1893,'' Haplospora 

 globosa Kjellm. was found at Millport, Cumbrse, N.B., and 

 then, in 1894,^ at the same place, the very much rarer 

 Scaphospora speciosa Kjellm. An exceedingly small quan- 

 tity of the latter was obtained, only sufficient to yield one 

 herbarium specimen and a few microscope slides In 1895
