Species description:
Thallus small to medium but not minute; lobes averaging to more than 1.5 mm wide, always dorsiventral; isidia present or absent, distinctly wrinkled upper surface AND
Lobe margins naked; isidia, if present, naked AND
Lobes narrow, proportionately elongate, more or less erect and bearing distinctly swollen tips; lobe tips averaging to 0.4 mm thick when moist, often strongly collapsed-wrinkled when dry; over soil in arid inland localities

OR

Thallus minute; lobes averaging to less than 1 mm wide, occasionally cylindrical; true (i.e., basally constricted) isidia absent (Exception: isidia occasionally present in L. schraderi) AND
Thallus entirely or at least primarily erect-cylindrical (primary lobes may be partly dorsiventral) AND
Over soil (also rarely over bases of trees), often in semi-arid localities; terminal lobes often somewhat contorted, but never distinctly constricted at intervals AND
Lobe tips in part strongly wrinkled

Comments:
The local material might be referred to L. turgidum Nyl., though according to P.M. Jørgensen (Bergen, pers. comm., 1993) that species appears to be merely a growth form of L. schraderi.
