Graphis australosiamensis Sutjaritturakan & Kalb (2014: 321) .

Type:— THAILAND. Chumphon province: Mueang district, tambon Tak Daet , on Areca catechu , 7 m, 10°29’03’’ N, 99°10’32’’ E, 12 December 2007, J. Sutjaritturakan & S. Yaowalert 6 ( MSUT, holotype, hb. K. Kalb, isotype) .

Thallus corticolous, white-grey, continuous, surface uneven, dull. Lirellae prominent, with a lateral, rarely with a complete thalline margin, short to elongate, straight, curved or sinuose, usually unbranched or sparsely branched, up to 6 mm long, labia convergent, entire for a long time, but becoming striate with age, not pruinose, disc not visible from above ( tenella - or marginata -morph). Exciple laterally carbonized, but converging sometimes below; hymenium densely inspersed, type A; ascospores 1/ascus, hyaline, richly muriform, 70–120 × 20–28 μm.

Chemistry: norstictic acid (major), connorstictic acid (minor).

Distribution and habitat:—Not yet recorded from outside of southern Thailand; here recorded for the first time from Pattani province, where it was growing on bark of an unidentified tree near a waterfall.

Remarks:—Since the first description of this species, we have made further collections which enabled us to refine the description and make additions to the distribution. Habitually, this species is similar to Allographa atrocelatoides (see above), but that species differs in having a clear hymenium and in lacking lichen substances.

Material from Thailand examined:— Songkhla province: Rattaphum district and Chumphon province: Lamae district, Pathio district , Mueang district , Tha Sae district and Lang Suan district ( Sutjaritturakan et al. 2014), and a new record from Pattani province: Khok Pho district , tambon Thung Phala , in the area of Aran Warin Waterfall , on bark of an unidentified tree, 06°38’46’’ N, 101°08’37’’ E, 105 m, 11 August 2012, J. Sutjaritturakan 4760 (hb. K. & J. Kalb 42247) .

* Graphis bakeri Vainio (1921b: 253) . Fig. 3E . Type:— PHILIPPINES. Luzon: subprov. Laguna, Los Banos , on Ficus nota, C. F. Baker 547, December 1912 (TUR-V. 27874!, lectotype,

designated by Lücking et al. 2009).

Thallus corticolous, whitish, whitish gray to off-white, slightly glossy or dull. Lirellae erumpent, with a lateral thalline margin, elongate, cuved or sinuous, irregularly branched, 0.5–4 mm long, labia white pruinose, convergent or very slightly divergent, entire ( caesiella -morph), disc usually not or only rarely seen from above. Exciple laterally carbonized; hymenium clear; ascospores 8/ascus, hyaline, transversely septate, 7–9-septate, 20–30 × 6–8 μm (Thai collections), halonate, 5–9-septate, 15–43 × 6–8 μm (protologue).

Chemistry: salazinic acid (major), ± consalazinic acid (trace), ± norstictic acid (trace) (anal. K. Kalb).

Distribution and habitat:—Eastern palaeotropical, so far only known from the Philippines and here reported from Thailand for the first time. In Thailand, this species is growing on deciduous trees in open situations from 3–95 m above sea level.

Material from Thailand examined:— Chumphon province: Pathio district, tambon Chum Kho, ca. 500 m N of Pathio-Tong junction, in a secondary rainforest on bark of an unidentified tree, 20 m, 10°44’18’’ N, 99°23’18’’ E, 4 December 2015, J.
