### Taxonomy
However, phylogenetic analysis suggests that it should be recognized as an independent species. Unfortunately, we did not obtain the type specimen or molecular data related to the origin of _S. bispora_ var. _monospora_, so we can only describe this specimen as a similar species to _S. bispora_ var. _monospora_, revised to _Pseudosolorina bispora_ var. _monospora_ ([PERSON].) [PERSON] and [PERSON]. Further research is necessary to determine whether they are indeed the same species. Specimens examined: China, Qinghai Prov., Zhiduo Co., 33 deg48'03.32'' N, 95 deg13'57.24'' E, Alt. 4436 m, 18 September 2020, [PERSON] et al., XY20-828; Maduo Co., 35 deg06'16.62'' N, 98 deg54'22.97'' E, Alt. 4260 m, 14 September 2020, [PERSON] et al., XY20-2943; Maduo Co., 34 deg49'40.56'' N, 99 deg02'03.48'' E, Alt. 4578 m, 13 September 2020, [PERSON] et al., 20-67082. _Pseudosolorina hepatizon_ [PERSON] and [PERSON], sp. nov. **Figure 7**  
Fungal Names: FN 572275  
Type: China. Yunnan Prov., Shangrila city, Birong Valley, 26 deg39'05.72'' N, 99 deg44'15.57'' E, Alt. 3089 m, 15 July 2023, [PERSON] et al., 23-75286 (Holotype KUN)  
Etymology: Referring to its hepatolor thallus. Diagnosis: This species has a hepatolor upper surface when dry, while most other species of _Pseudosolorina_ display brown, greyish-brown, or pale hues. _P. hepatizon_ has a single photobiont layer containing both cyanobacteria and chlorophytes and lacks secondary metabolites. Description: Thallus: large foliose, dorsiventral, heteromerous, lobate, up to 9 cm in diam. ; Lobes: rounded, 10-20 mm; Upper surface: green-gray when wet, hepatolor or gray-brown when dry, smooth to scabrid; Upper cortex: paraplectenchymaltous, colorless, 60-150 \(\upmu\)m thick; Medulla: 200-300 \(\upmu\)m thick; Photobiont: _Asterochloris_ and _Nostoc_, single photobiont layer with both blue and bright green cells, 100-220 \(\upmu\)m thick; Lower cortex: lacking; Lower surface: white, indistinctly veined, brownish tometose, without cephalodia, with clusters of simple or branched rhizines; Apothecia: large, rounded, irregularly scattered, sunk in depressions in the upper surface, red-brown to black, slightly concave, thalline margin absent; Asci: clavate, _Peltigena_-type, 4-spored; Ascospores: red-brown or dark brown, 1-septate with a median constriction, ellipsoid to fusiform, wall non-uniformly thickened, surface ornamented broad reticulating ridges and irregular lacunae, measured 42-53 \(\times\) 18-25 \(\upmu\)m.  
Chemistry: No lichen products detected by TLC. Ecology and distribution: It is distributed in high-altitude areas and primarily found on calcareous soils on stones, typically growing alongside or on bryophytes. This species is only known from Yunnan Province of China. Note: Specimens representing this species were formerly categorized as _Solarina sinensis_ based on their morphological characteristics. In this study they have been divided from _P. simensis_ to form the new species _P. hepazion_. Despite distinct chemical characteristics, _P. simensis_ contains secondary metabolites such as methyl gyrophorate and tentioirin, whereas _P. hepazion_ lacks any secondary metabolites; it was previously identified as an acid-deficient variant of _S. simensis_ ([PERSON] and [PERSON] 1986). DNA evidence supports its classification as a distinct species in the realm of scientific research.
