Antlierids occur on the same plant as the cystocarps. The branches are 
the result of endogenous growth, as in Pytiphlcea and other genera. 
Fucaceae * * * § — Herr E. Gruber describes in detail the structure of a 
number of species of Fucaceae, and classifies the genera into six groups, 
viz. the Durvilleae, Hormosirere, Fuceae, Loriformes, Cystosireae, and 
Sargasseae. The Durvilleae comprise the genera Durvillsea (including 
SarcopJiycus and Ecldonia ) and SplacJinidium (?) ; the Hormosirem, Hor- 
mosira and Notheia ; the Fuceae, Fucus, Pelvetia, Xiphophora, Ascophyllum , 
Axillaria, Seirococcus, Scytothalia , Phyllosporci, and Marginaria ; the 
Loriformes consist of Himanthalia alone ; the Cystosireae are divided 
into Bilaterales and Badiares ; the former including Halidrys, Eifurcaria , 
Carpoglossum , Myriodesma (?), Platythelia, and Platyldbium ; the latter 
Cystoseira , Cystophyllum, 1 tormophysa, Coccophora, Scaberia (?), Cysto- 
pliora , and Langsburgia ; the Sargasseae comprise Anthopliycus , Carpo- 
phyllum , Contarinia , Pterocaulon , Sargassum, and Turbinaria. 
Hew Genus of Freshwater Phseosporese.t — Under the name Ueri- 
baudiella, M. M. Gomont establishes a new genus of Halfsiaceae, with the 
following diagnosis : — Planta phaeosporina, Crustacea, e strato initiali 
arete appresso et filis erectis inde ortis formata ; stratum initiate mono- 
stromaticum, ambitu crescens, cellulis connatis secus series dichotomas 
flabelliformiter arcuatas ordinatis constitutum ; fila erecta libera, ar- 
ticulata, monosiphonia, abundanter et plerumque dichotome ramosa, 
ramis fastigiatis, arete appressis ; sporangia unilocularia in soros baud 
aggregata, transformatione cellulse superioris filorum ascendentium orta, 
poro apicali vacuefacta ; sporangia plurilocularia usque adhuc ignota aut 
nulla. The genus is nearly allied to Symphyocarpus and Litlioderma. 
H. arverneiisis sp. n. forms a brown coating on mica-schists in running 
water in Haute Auvergne, 
Hew Cephaleuros.J— Under the name Ceplialeuros Coffcse, Herr F. 
A. F. C. Went describes a new species of this genus of Chroolepideae 
parasitic on leaves of the coffee plant, and follows the various stages of 
its development. The pigment is blood-red. It causes black spots on 
the leaves, and the blackening and drying up of the fruit. 
Pseudocodium, a new Genus of Siphonese.§ — Under the name 
Pseudocodium De Vriesii g. et sp. n., Mdme. Weber van Bosse describes 
a new Siphoncan Alga from S. Africa, with the following diagnosis : — 
Frondes virides, dichotomi ; rami cylindrici, omnino consimiles, ex filis 
tubulosis subparallelis longitudinaliter dispositi, apice iterum atque 
iterum divisi, contexti, articuli exteriores apice in vesiculos oblongos evo- 
luti, corticem pseudoparenchymaticam formantes ; rhizini filiformes cum 
granulis sabulosis et inter se dense intertextis ; propagatio ignota. 
Notwithstanding its outward resemblance to Codium, the authoress con- 
siders the genus more nearly related to Halimeda.

detail the structure and development of the galls produced on species
