Graphina mendax (Nyl.) Mull. Arg. but that species has larger hyaline ascospores and 
contains norstictic acid. 
Specimens examined: Northern Territory: Wangi Road, Walker Creek, 68 km SSW of Darwin, 
Streimanti 8800, Jan 1985 (CANB); Melville Island, Conder Point, Streimann 42494, Apr 1989 
(CANB). 
Queensland: 2 km S of Forrest Beach, 15 km SE of Ingham, Elix 15975 p.p., June 1984 (CANB). 
Phaeographina chrysenteron (vide infra) (Mont.) Mull. Arg. (Fig. le, 2e) 
(Muller 1891: 52). 
Graphis chrysenteron Mont., 
(Montagne 1842: 268). 
Type: Guyana Gallica: s. loc., Leprieur 23; (holo P) fide K. Kalb, in litt. 
Thallus pale olive green, corticolous, surface smooth and shiny; apothecia lirelliform, 
white, numerous, conspicuous, crowded, sessile, straight, curved or sinuous, 
sometimes branched, 1—3(-5) mm long, 0.5-0.6 mm wide; proper exciple complete, 
reddish brown; hymenium 150-200 pm tall; ascospores 8 per ascus, brown, 50-60 pm 
long, 12-16 pm wide, 10-12 x 2-6 locular. 
Chemistry: stictic acid (fide K.Kalb in litt.) 
Distribution: occurs in New Caledonia, Indonesia, Hawaii and Brazil and, in 
Australia, in Queensland. The only reported substrate in Australia is Acacia. 
Notes: Phaeographina chrysenteron is characterised by the conspicuous lirellae, the large 
brown muriform ascospores and the presence of stictic acid. The species was first 
reported from Australia by Muller (Muller 1891) who based his report on specimens 
collected on Mt Bellenden Ker and sent to him by the Colonial Botanist F.M. Bailey. 
A recent examination of Bailey's specimen (BRI 492632) found it to contain stictic acid 
but no ascospores were seen. Another older specimen from Queensland labelled 
Phaeographina chrysenteron [J. Shirley AQ 721319 (BRI)] lacked lichen compounds and 
is identified as Graphina repleta (Stirt.) Shirley. Phaeographina chrysenteron resembles 
Graphina repleta var. stictica A.W. Archer (Archer 1999) but is distinguished from that 
taxon by the smooth lirellae and the pale brown ascospores. 
Muller's epithet 'chrysentera' has been corrected to 'chrysenteron' as chrysenteron is 
a Greek noun in apposition and does not change. 
Specimen examined: Queensland: Black Mountain, 25 km NW of Kuranda, Elix 17505, Jul 1984
