on the matted and exposed roots of various herbs or shrubs, ravines of the Chain Hills, 
Otago: W. L. L.: in all cases sterile, but spermogones sparingly distributed in some 
specimens. The plant is of a Peltigeroid type, and resembles in general aspect our 
§. sylvatica. The thallus is of a dull or dirty lurid or brown, a colour that is unusual 
among the New-Zealand Sticte, in which more brilliant tints, especially yellow, pre- 
dominate; its margins are generally more or less fringed with coralloid granulations, 
(resembling young states of Spherophoron or Stereocaulon), which are really extremely 
minute squamules. In this tendency to multifid division of the edge of the thallus, and 
in other features, this species resembles Sticta dissimulata, and so closely that I know of 
no sufficient characters for their specific separation. Moreover Stictina dissimilis and 
Sticta dissimulata, in their variations, resemble, save as to the colour of the medullary 
tissue, Sticta Urvillei. They have, further, many characters in common with Sticta 
damecornis.

Both sterile. 
On rocks, Coal River, near Richmond, Tasmania, both sterile and fertile. Sterile 
specimens are abundantly sorediiferous, the soredia being yellow and both marginal and 
central ; thallus brown or chestnut-coloured, with a somewhat lacunose surface. Plant 
has a general resemblance to the British Sticta scrobiculata. Fertile specimens are non- 
sorediiferous. Apothecia chiefly central and crowded, a few marginal ; substipitate, base of 
attachment to thallus slight; disk deep brown, border generally regular, thin, oinnes 
waved or involute. Spores ellipsoïd, 1-septate, brown (apothecia mostly old), 00066" to 
‘00083” long, 00033” to “00040” broad.
