K– or K+ dirty brown, C–, KC+ red/brown, P+ brick red;
protocetraric acid, ± fatty acids. Distinguished from
P.
dilatatum
by the presence of isidia and from
P. tinctorum
by
the presence of protocetraric rather than lecanoric acid.
Ecology and distribution:
Corticolous in a disturbed
evergreen forest at 1350 m, and in mixed deciduous forests
from 420 to 800 m, common. Reported from Asia, Australia,
Papua New Guinea (DIVAKAR & UPRETI 2005; ELIX
1994e; WOLSELEY et al. 2002) and the Pacific
(LOUWHOFF & ELIX 2000).

Hale ex DePriest & B.W. Hale,
Mycotaxon 67: 207 (1998)
Description:
Thallus to 5-8 cm wide, closely adnate; lobes
4–8 mm wide, eciliate; upper surface dull, emaculate, grey,
with mainly simple, robust isidia; lower surface black with
shining brown erhizinate margin; rhizines sparse, simple.
Cortex K+ yellow; atranorin. Medulla K– or K+ dirty brown,
C–, KC+ red/brown, P+ brick red; protocetraric acid.
Distinguished from
P. dilatatum
by the presence of isidia and
from
P. tinctorum
by the presence of protocetraric rather than
lecanoric acid;
P. saccatilobum
is usually corticolous has has
thinner, fragile isidia.
Ecology and distribution:
Described
as saxicolous from Hong Kong, and reported as corticolous
from Chiang Mai, Queen Sirikit Botanical Garden by
POOPRANG et al. (1999); we have not examined the
specimen.
