Phaeographis pseudomelana Mull. Arg. (Fig. If, 2f) 
(Muller 1895: 321). 
Type: Queensland: sine loc., /. Shirley 1838, 1893 (holo G). 
Thallus pale fawn, thin, corticolous, surface smooth and shiny; apothecia lirelliform, 
conspicuous, scattered, sessile, open, straight, curved or sinuous, often branched, 
terminally acute, with a thin thalline margin, 2-4(-6) mm long, 0.15-0.25 mm wide; 
proper exciple apically carbonised; hymenium 100-125 pm tall; disc black, white- 
pruinose; ascospores 8 per ascus imbricate 1-seriate, pale brown, 17-20 pm long, 6-8 
pm wide, 4-locular. 
Chemistry: no compounds found. 
Also examined: Queensland: Rainbow Beach, c. 50 km W of Gympie, Lumbsch 10995j, Oct 1994 
(ESS); Kirrima State Forest, 24 km WNW of Cardwell, Elix 15685, June 1984 (CANB). 
New South Wales: Monga State Forest, J. Everett 947, May 1986 (NSW). 
Phaeographis pseudomelana is characterised by the open lirellae, the apically carbonised 
proper exciple, the 4-locular ascospores and the absence of lichen compounds. It 
closely resembles P. subintricata (C. Knight) Mull. Arg. and is only distinguished from 
that species by the apically carbonised proper exciple, in contrast to the laterally 
carbonised proper exciple in the latter species. The type and other specimens 
examined possess 4-locular ascospores in agreement with Muller's drawing in sched. 
although the protologue refers to 6-locular ascospores. Shirley (1896) reported the 
species from Sankeys Scrub [Brisbane].
