It is primarily distinguished by its 2 - spored asci, whereas all other species of Willeya have 4–8 - spored asci.</p><p>In the phylogenetic tree, W. bispora forms a sister branch to a clade comprising W. diffractella, W. fusca, W. nepalensis and W. protrudens . All four species share green to dark brown thalli, protruding perithecia (either entirely or partly covered by the thallus), and relatively small ascospores. Morphologically, W. bispora can be readily separated from these four relatives. Willeya fusca has a globose centrum (250–300 µm in diameter), longer hymenial algal cells, 8 - spored asci, and smaller ascospores measuring (20 –) 22–28 (– 30) × (9 –) 10–13 (– 15) µm. W. diffractella differs in having perithecia that are immersed with the ostiole either prominent or not, asci with (6 –) 8 spores, and even smaller ascospores (18–23 × 10–11 µm). W. protrudens is characterized by protruding perithecia (entirely or only partly covered by the thallus), 8 - spored asci, and smaller ascospores, (20 –) 22–30 (– 32) × (9 –) 10–14 (– 15) µm. Willeya nepalensis bears ascospores of (19.5 –) 20–21.6 – 23.5 (– 25) × (9 –) 10–10.9 – 12 µm. Furthermore, W. bispora is distinct from Willeya honghensis (H. Harada &amp; Li S. Wang) Orange, a species not closely related in our phylogeny. Compared to the latter, W. bispora has a thinner thallus (92–99 µm vs. 200–230 µm in W. honghensis), a developed involucrellum and broader ascospores (14–20 µm vs. 10–13 µm wide).</p></div>	https://treatment.plazi.org/id/3CDF122AB1A454238DB8AC340718D3C1	Public Domain	No known copyright restrictions apply.

Although we did not examine specimens of this species directly, its phylogenetic position was inferred from GenBank sequences included in our multigene analysis. Important morphological features of W. honghensis include a well-developed, cracked thallus with black-sided areoles, immersed perithecia with only the extreme apex visible, and the occasional presence of pycnidia (Orange and Chhetri 2022). In the protologue, perithecia are depicted as forming rather distinct projecting mounds, though anatomical sections suggest this character is not always well developed (Harada and Wang 2006; Orange and Chhetri 2022). The species is distinct from W. tetraspora by its shorter ascospores (Aptroot 2016).</p><p>In our phylogenetic tree, W. honghensis occupied a basal position within Willeya . In the maximum likelihood (ML) analysis, it formed a weakly supported sister relationship with W. irrigata (BS = 62 %, Fig. 1), whereas in the Bayesian inference (BI) tree (Suppl. material 1), it appeared as a separate lineage, parallel to both the W. irrigata clade and the remaining Willeya species. This placement is partially consistent with the findings of Orange and Chhetri (2022), who recovered W. honghensis as basal to a well-supported clade comprising Endocarpon species rather than among other Willeya species. The discrepancy between our results and those of Orange and Chhetri (2022) may be due to differences in taxon and gene sampling. Further studies with additional gene regions and broader taxon coverage are needed to resolve the phylogenetic position of W. honghensis with confidence.</p></div>	https://treatment.plazi.org/id/A16856AF175B510DB75B9D68F8B57AA1	Public Domain	No known copyright restrictions apply.

Minor differences include a thinner thallus in the Chinese material (59–87.4 μm vs. 130–290 μm in Japanese and Nepalese) and slightly broader ascospores. The hymenial algae are spherical in Chinese and Japanese specimens (2–3 μm diam.) but broadly ellipsoid in the Nepalese specimen (2.5–3.3 × 2.5–2.9 μm). An epinecral layer is present in the Japanese type but not observed in Chinese or Nepalese collections. Despite these subtle variations, the overall morphological correspondence is strong.

The species exhibits considerable morphological and genetic variation across its range. Gueidan et al. (2014) divided the Vietnamese and Australian specimens into two well-supported, genetically distant subgroups. They noted that morphological and anatomical characters could not clearly distinguish members of the two subgroups, and together with observed morphological variation among the four Australian specimens studied, they concluded that W. pallidipora most likely represents a species complex, referred to as W. pallidipora s. lat. (Gueidan et al. 2014). Subsequent studies included a Nepalese specimen that clustered with the Vietnamese and Australian specimens, further supporting the complex nature of this taxon (Orange and Chhetri 2022).</p><p>In our phylogenetic tree, the Chinese specimen from Shaanxi province clustered within the W. pallidipora s. lat. clade ( W. pallidipora 1, Fig. 1), which also contains the Nepalese specimen of W. eminens . This placement suggests that the Chinese specimen may represent a distinct lineage, possibly a cryptic species. However, morphological comparisons with specimens from other regions did not reveal stable diagnostic characters. Specimens from Nepal, Australia, and China share a pale green to dark grey-brown thallus with few cracks, immersed to completely immersed perithecia, and elongate-cylindrical hymenial algae. Ascospore sizes vary among regions: Nepalese specimens 20.5–22.5 × 9.5–11 μm, Australian specimens 18–28 × 9–14 μm, and Chinese specimens 20–24 × 9.7–13 μm (Fig. 7). These overlapping spore dimensions, combined with the lack of clear morphological discontinuities, prevent a reliable separation of the Chinese material from other populations.</p><p>Given the high morphological and genetic diversity within the W. pallidipora complex and the absence of consistent distinguishing features, we tentatively assign the Chinese specimens to W. pallidipora s. lat. Future studies with denser sampling, including additional gene regions and examination of type material across the complex, are needed to resolve the taxonomic status of the Chinese populations.</p><p>Chemical spot tests on the thallus yielded negative reactions (K –, C –, KC –, UV –), and no lichen substances were detected by TLC.</p><p>Specimens examined.</p><p>China • Yunnan Province, Mangshi, <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=98.588615&amp;materialsCitation.latitude=24.428888" title="Search Plazi for locations around (long 98.588615/lat 24.428888)">Mengbanna Xi Exotic Garden</a>, 24°25'44"N, 98°35'19"E, alt. 940 m, on rock, 11 August 2022, Yanfei Zhao YN 221805 (LCUF) ; • Shannxi Province: Baoji City, Mount Taibai, <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=107.89&amp;materialsCitation.latitude=34.04778" title="Search Plazi for locations around (long 107.89/lat 34.04778)">Lianhuafeng Waterfall</a>, 34°02'52"N, 107°53'24"E, alt. 1135 m, on siliceous rock, 6 June 2025, Xin Yi Wang SQ 250758-1 (LCUF) .</p></div>	https://treatment.plazi.org/id/E4E59708CFED550FB4A3872043B99B75	Public Domain	No known copyright restrictions apply.
