Our objective was to explore the diversity and distribution of lirellate Graphidaceae occurring in seven
different forest types (coniferous forest, CF; dry dipterocarp forest, DDF; dry evergreen forest, DEF; lower
montane scrub, LMS; lower montane rain forest, LMRF; mixed deciduous forest, MDF; and tropical rainforest,
TRF) at Phu Luang Wildlife Sanctuary. Five hundred and thirty-one specimens were collected and identified to
ninety-one taxa in sixteen genera (Acanthothecis, Carbacanthographis, Diorygma, Dyplolabia, Glyphis, Graphis,
Fissurina, Hemithecium, Leiorreuma, Pallidogramme, Phaeographis, Platygramme, Platythecium, Sarcographa,
Thalloloma and Thecaria). Thirty-five taxa are first records for Thailand, while 17 taxa were expected to be new
species to science. The highest diversity, 63 species, was found in LMS, while in LMRF (36 species), MDF (31
species), DDF (20 species) and TRF (14 species) were collected, and the lowest diversity in DEF (9 species)
and CF (8 species). The genus Graphis showed the highest diversity with 35 species, and Dyplolabia afzelii,
Diorygma hieroglyphicum, Graphis streblocarpa, Pallidogramme chrysenteron and Phaeographis sp. 2 are the
most common species and are widespread in almost all forest types.

Graphidaceae lichens collected from the Kalahan Forest Reserve in Imugan, Santa Fe, Nueva Vizcaya,
were evaluated for their morpho-anatomical and chemical features. Taxonomic characters of thallus (cortex,
texture, color), ascocarp/lirellae (morph, form, emergence, branch, color, striation, thalline margin, rim color,
disc color, pruina), exciple (carbonization), hypothecium (carbonization), hymenium (inspersion), and ascospore
(number per ascus, shape, septation, number of locules, length, width, color and color reaction to Iodine solution)
were observed and described. A total of 52 species distributed in 16 genera were identified. Two of the species
are suspected to be species novae. Only three of the 52 species are thelotremoids; the rest are all graphidoids.
Two-way hierarchical clustering of the identified lichens showed that lirellae morphology determines major
groupings while ascospore shape and iodine reaction distinguish the genera Graphis, Thelotrema, and Glyphis.
There were significant differences in the majority of the morpho-anatomical features between the clusters. There
was no significant difference in the lichen acids present in them.
