Marine Fungi Iniperfecti.

SPOROTRICHUM maritimum nov. SP. (Fig. 3, 6-7). 
Mycelium 1-1*5// in diameter, procumbent, vaguely branched ; 
conidia borne singly or in groups of two or three on short simple 
spinose conidiophores or sterigmata, continuous, elliptical, hyaline, 
5 x 2/x. 
Hab. Laminaria fronds. Dorset. 
The creeping, delicate mycelium forms a loose web over the 
surface of the fronds. All over the hyphae arise short, pointed, 
fertile branches bearing conidia (Fig. 3, 6). Frequently they arise 
on sterigma-like branches. This fungus may easily escape obser¬ 
vation, as its mycelium ramifies along the surface at the base of the 
conidiophores of Cladosporium or mixed with the chains of 
Fusidium. 
Cercospora sauna nov. SP. (Fig. 4, 7-5). 
Mycelium hyaline or slightly coloured ; conidiophores simple 
or slightly branched with terminal or sub-terminal swellings from 
which arise the conidia ; conidia varied, olive-green to brown in 
colour, short broad forms 30-45// x 8-10// and 3-5 septate, long 
types, 50-75// x 6-9// with 5-9 septa. 
Hab. Saprophytic on various seaweeds along the coast of 
Aberdeen, Ayrshire, Dorset and Orkney.
