HOOPERIA J. As. (1896] Anal. algol. cont. III, pag. 89 (Etym. a 
cl. J. HooPER, phycologo americano), Chylocladig sp. Harv. — 
Frons molliter gelatinosa, teretiuscula, quoquoversum ramosa, 
tubulosa, filis cavitatem percurrentibus fere nullis instructa, peri- 
pherico strato cellulis rotundato-angulatis, interioribus majoribus, 
exterioribus minutis, contexta. Cystocarpia ad ramos lateralia, in- 
ira periearpium externum $globoso-ovatum, nucleum adparenter 
simplicem, nullo adparatu filorum cinctum, foventia; nucleus car- 
posporis obovatis, a placent: basilaris valid:e ramis exeuntibus in 
pedicello tenuiore terminalibus, demum arctissime stipatis consti- 
tutus. Tetrasporangia in maculis ramulorum superficialibus nema- 
theciose evolutis, quasi definità lineà cireumseriptis provenientia, 
intra cellulas infraeorticales generata, magna, rotundata, trian- 
gule divisa. 
Obs. Vrondes et tetrasporangiorum evolutio ut in genere CAylo- 
cladiía Grev., cystocarpia vero omnino differentia. Cystocarpium 
juvenile longitudinaliter per mediam partem sectum monstrat pla- 
centam validam a fundo placentari sursum carpostomium versus 
adscendentem, ramis subtrichotome divisis decompositam, ramellis 
ultimis singulis in carposporas obovatas transmutatis; adultius 
monstrat placentam. breviorem et carposporas pedicellis multo lon- 
gioribus atque admodum tenuibus quasi gelatinosis suffultas, po- 
tius, his pedicellis forsan demum subdissolutis, in nucleum con- 
globatas. Carpostomium proprium vix adest sed apex eystocarpii 
paullisper porrectum demum, ut videtur, disrumpitur.
