Archer, Phaeographis and Phaeographina (Graphidaceae) 
339 
Chemistry: no lichen compounds found. 
Distribution: endemic; known only from north-eastern Queensland. 
Notes: Phaeographina hadrospora is characterised by the inconspicuous lirellae (hidden 
by the large thalline margins), the absence of lichen compounds and the large pale 
brown, muriform ascospores. Immature ascospores are smaller and hyaline. This new 
species resembles P. tumulata (Nyl.) Mull. Arg. but the ascospores in that species are 
14-18 pm long, 9-11 pm wide and 4 x 1-3-locular (Nylander 1868). 
Large ascospores (c. 200 pm long) are uncommon in the genus Phaeographina; one 
species with large ascospores, P. balfourii Mull. Arg., was described from Socotra 
(Muller 1888b), but that species has much-branched, immersed lirellae and a reddish 
brown proper exciple. Phaeographina hadrospora is thus distinct from this species. 
Etymology: The epithet hadrospora is from the Greek, hadros, large, well-developed, a 
reference to the large ascospores.

Phaeographina impudica A.W. Archer, sp. nov. (Fig. li, 3c) 
Phaeographina platyloma similis sed ascosporis majoribus et lirellis sulcatis differt. 
Type: Queensland: Mcllwraith Range, Lankelly Creek, 11 km from Coen, 13°57'S, 
145°15'E, G. Butler 562A, Aug 1978 (holo CANB). 
Thallus pale greyish green, thin, corticolous, surface subtuberculate and slightly shiny; 
apothecia lirelliform, conspicuous, scattered, sessile, black, lips closed, slightly sulcate, 
straight, curved or sinuous, rarely branched, 1-4 mm long, 0.4-0.6 mm wide, to 0.4 mm 
tall, with a conspicuous thalline margin; proper exciple laterally carbonised; 
hymenium 180-220 pm tall; ascospores 1 per ascus, pale brown, elongate-ellipsoid, 
(125-)135-180 pm long, (25-)30-40 pm wide, densely muriform. 
Chemistry: no lichern compounds found. 
Distribution: endemic; known only from north-eastern Queensland. The only 
reported substrate is Alphitonia. 
Notes: Phaeographina impudica is characterised by conspicuous lirellae with the proper 
exciple laterally carbonised, exposed and sulcate, the large ascospores and the absence 
of lichen compounds. The species is thus distinguished from P. pudica (Mont. & Bosch) 
Zahlbr., described from Indonesia, which has barely exposed lirellae (hence the 
epithet) which are not sulcate (Redinger 1936a; Nakanishi 1977). The ascospores in 
that species are reported to be 100-150(-180) pm long and 20-32(-40) pm wide. 
Phaeographina platyloma Mull. Arg. (Muller 1882) resembles P. impudica but the lirellae 
in that species are not sulcate and the ascospores are smaller, 78-117 pm long, 26 pm 
wide (Nakanishi 1977). Phaeographina muelleri A.W. Archer (Archer 2000) has similar 
ascospores and lacks lichen compounds but that taxon has conspicuously open lirellae 
with an apically carbonised proper exciple. 
Specimens examined: Queensland: Big Tableland, 26 km S of Cooktown, Elix 17284, July 1984 
(CANB); Eungella National Park, Day 87.13, July 1987 (CANB); Atherton Tableland, between 
Ravenshoe and Atherton, Lumbsch 5432a, Aug 1987 (herb. Lumbsch). 
Phaeographina litoralis A.W. Archer, sp. nov. (Fig. lj, 3d) 
Phaeographis dendroide similis sed ascosporiis majoribus muriformisque, et acido 
stictico deficienti differt.
