OF SOUTH AUSTRALIA. 
383 
long, linear-oblong, obtuse, tapering at the base, margin sinuate or incised 
in an alternately pinnatifid manner; lobes few, erect, linear-oblong, with 
an immersed midrib, becoming faint towards the apices. The surface is 
thickly covered with minute echinated warts, giving it a rough feel ; warts 
both large and small. Colour dark brown-red. Substance hard and rigid. 
Does not adhere to paper. 
West Australia (Fremantle). 
Thamnoclonium dichotomum J. Agardh. 
Fronds complanate, flabellately expanded, at length subdichotomous ; 
young branches cuneate-spathulate, obtuse, at length with bifid or trifid 
apices from the ancipitous plane frond; verrucose, forming immediately 
short, truncate, equal strata of cells on the plane face, leaving minute, 
naked, interstitial spaces ; older branches at length denuded at base, sub- 
terete. 
South Australia (Gulf St. Vincent). 
BLASTOPHYE J. Agardh. 
Frond laciniate, proliferous from the margin or from within the margin, 
formed of three layers; the inner of filaments, articulate and densely inter- 
woven; the middle layer of rotund-angular cells; the outer of rotund, 
vertical cells, almost in rows. Cystocarps immersed in the frond, the 
nucleus strong and apparently simple. Carpospores are numerous, minute, 
and grouped irregularly. 
Blast ophye Wilsoni J. Agardh. 
— Cryptonemia Wilsoni J. Agardh. 
Frond 2 cm. wide, 6 cm. to 10 cm. long, cuneate above the stipe, lan- 
ceolate, linear, di-trichotomous, more or less irregular; more often the 
phyllodia rise from the entire margin, sometimes pinnate or palmate; the 
proliferous young phyllodia obovate-ligulate, the fully developed ones 
lanceolate and linear. Cystocarps sparse, irregularly spread over the adult 
frond. Substance very membranous. Colour bright red. 
South Coast of Australia. 
Family DUMONT IACEAE (Bory) Schmitz. 
DASYPHLOEA Montague. 
Frond cylindrical, dendroid, membranaceo-cartilaginous, coated 
externally with microscopic hyaline hairs and formed of a central articu- 
lated filament and two strata; the intermediate stratum composed of 
longitudinal, branching, excurrent filaments ; the cortical membranous, of 
roundish-angular cells. Cystocarps immersed in the ramuli, containing 
moniliform spore-threads issuing from a central placenta. Tetrasporangia 
zonate, in wart-like nemathecia.
