An unnamed saxicolous species of Phaeogrciphis from Queensland with 4-locular 
ascospores (H. Streimann 56404, CANB) is differentiated from P. eludens by the 
tuberculate thallus and the conspicuous thalline margins of the lirellae. 
Phaeographis necopinata A.W. Archer & Elix (Fig. Id, 2d) 
(Archer & Elix 1999: 92). 
Type: Queensland: Great Dividing Range, Mount Baldy, 4 km S of Atherton, on 
Alphitonia, J.A. Elix 16233, June 1984 (holo CANB). 
Thallus off-white, thin, corticolous, surface smooth and shiny; apothecia lirelliform; 
lirellae numerous, conspicuous, sessile, open, straight, curved or sinuous, sometimes 
in substellate clusters, with a thin thalline margin, 1-3 mm long, 0.3-0.5 mm wide, and 
clusters to 4 mm wide; proper exciple completely carbonised; hymenium 125-150 pm 
tall; epithecium matt black, epruinose or lightly pruinose; ascospores pale brown to 
brown, 8 per ascus, (25-)30-40 pm long, (8-)9-12 pm wide, (7-)8-locular. 
Chemistry: hypostictic acid (major), conhypoprotocetraric acid (trace) and 
hyposalazinic acid (trace).

(CANB). 
Phaeographis necopinata is characterised by the conspicuous lirellae, asci with eight 
ascospores and the presence of hypostictic acid. The lirellae may be terminally 
rounded or acute and the ascospores are predominantly 8-locular. Superficially the 
new species resembles Phaeographis dendritica (Ach.) Mull. Arg., but is distinguished 
from that species by the presence of hypostictic acid. Hypostictic acid is an uncommon 
compound in the Graphidaceae but is also found in two species from Brazil, viz. the 
holotype of Graphina albostriata (Vain.) Zahlbr. (TUR-V 27177) and a syntype of 
Graphina pseudosophisticata (Vain.) Mull. Arg. (TUR-V 27244A) (Archer & Elix 1999). 
These two taxa are conspecific. 
Phaeographis nornotatica A.W. Archer & Elix (Fig. le, 2e) 
(Archer & Elix 1999: 93). 
Type: Queensland: Mcllwraith Range, Llankelly Creek, 9 km NE of Coen, H. Streimann 
56937, Oct 1995 (holo CANB). 
Thallus dull fawn, thin, corticolous, surface smooth and shiny (chondroid); apothecia 
lirelliform, conspicuous, scattered, sessile, black, straight, curved or sinuous, 
sometimes branched, with a conspicuous thalline margin, lips open, disc black, fine 
white-pruinose, l-4(-6) mm long, 0.5-0.7(-0.9) mm wide, 0.4-0.5 mm tall; proper 
exciple completely carbonised, laterally thin, the base thick, c. 250 pm tall, tapering 
towards the base; hymenium c. 100 pm tall; ascospores 8 per ascus, pale brown, 
rounded cylindrical, 21-25 pm long, 6-7 pm wide, 6-locular. 
Chemistry: 4-O-demethylnotatic acid [nornotatic acid] (major) and hypoprotocetraric 
acid (minor).

Phaeographis nornotatica is characterised by the large conspicuous lirellae, the tapering 
base of the proper exciple and the presence of nornotatic acid. The species somewhat 
resembles P. exaltata (Mont. & v.d. Bosch) Mull. Arg. but the lirellae are larger and 
ta er, and the proper exciple and the chemistry differ. Phaeographis exaltata lacks lichen 
compounds. The new species is so far known only from the two specimens cited above.
