331 
Phaeographina species. 
Phaeographina arechavaletae Miill. Arg. (Fig. la, 2a) 
(Muller 1888a: 5). 
Type: Uruguay. Montevideo, J. Arechavaleta, s.n., no date (lecto G,fide Hayward 1977) 
Phaeographina banksiae Miill. Arg. 
(Muller 1893a: 59). 
Type: Australia. Victoria: Maffra, on Hymenanthera banksii, F.R.M. Wilson 879, 1892 
(holo G; iso NSW). 
Thallus pale greenish grey, thin, corticolous, surface smooth and slightly shiny; 
apothecia lirelliform, black, numerous, conspicuous, sessile to slightly immersed, lips 
closed, becoming slightly open, straight or curved, rarely branched, l-3(-4) mm long, 
0.2-0.3(-0.4) mm wide, with a thin evanescent thalline margin; proper exciple laterally 
carbonised; hymenium 125-150 pm tall; ascospores 8 per ascus, pale brown, ellipsoid, 
(20-)24-31 (-39) pm long, (10—) 12—15(—17) pm wide, 4-6 x 2-3 locular. 
Chemistry: no compounds found. 
Distribution: occurs in Uruguay, Paraguay, Argentina, New Zealand and eastern 
Australia. Reported substrates in Australia include Bursaria, Grevillea and 
Hymenathera. 
Notes: A comparison of the holotype of P. arechavaletae, the isotype of P. banksiae, and 
specimens of P. banksiae from Australia and P. arechavaletae from New Zealand 
(Hayward 1977) showed them to be identical. The species is characterised by a 
laterally carbonised proper exciple, small muriform ascospores and the absence of 
lichen compounds.
