Marine Fungi Impcrfecti. 
Hab. Saprophytic on Laminaria fronds. Dorset and Orkney. 
This species occurs on more or less regular patches of a pink 
colour on fronds cast up by the tide, being readily distinguished by 
the characteristic spots which stand out in marked contrast to the 
dark masses of Cladosporium on the same fronds. It has also 
developed on freshly collected material kept isolated in the 
laboratory, so that it seems capable of living also in the tidal zone 
but no trace, apart from scattered conidia, has been found on living 
fronds, so that it may be regarded as saprophytic. 
The young hyaline or older pink mycelium is localised, and 
upon the irregular discoloured patches, which it forms, are borne 
the semi-globose or pulvinate, closely aggregated sporodochia (Fig. 
5, 8). The conidia possess short pedicels rarely exceeding 10/x 
(Fig. 5, 9, 10). They are globose structures, irregularly septate, 
covered with a rough verrucose, reddish-brown coat except where 
attached to the pedicel. 
The variety of these species, representative of different sub¬ 
divisions of Fungi Imperfecti, would point to the existence of a 
fairly extensive flora. But their main interest does not lie so much 
in their numbers as in their halophytic adaptations, in the role 
they play along the tidal zone, and in their connections, if any, with 
some of the Pyrenomycetes already known. 
Some of the material for these notes has been secured through 
a grant from the Government Grant Committte of the Royal 
Society, to whom I wish to express my obligations.
