The specimen was preserved in formalin, and when washed and dried it 
collapsed to an almost film-like expansion, somewhat wrinkled on the surface 
and dark brownish-green in colour. The spores were so closely adherent 
that it was difficult to note the septa.

LEPIDOLEPTOGIUM A. L. Sm., gen. nov. 
Thallus squamosus, adpressus vel adscendens, maxima parte gonidiis 
impletus; hypothallus niger, interdum bene evolutus ; stratum corticale 
superius pleetenchymaticum.  Gonidia nostocacea, moniliformi-concatenata 
stratum medullare homæomerieum, vel in parte inferiore gonidiorum desti- 
tutum; cortex inferior non bene evolutus.  Apothecia parum elevata ; 
excipulo thallino instructa ; sporze octontæ, simplices, incolores. 
The above genus, owing to the cellular upper cortex, differs from Lepido- 
collema as Leptogium differs from Collema.
