03C2878AFFCAA17ACE82EAAFFA708324.taxon	description	Similar to P. himalayensis but differs by the absence of pseudocyphellae on thallus, the smaller ascospore size, the brown to brownish orange internal stipe with a white lower part, and lacks zeorin. Type: — INDIA. Kerala: Idukki district, Mathikettan Shola National Park, Karadippara, 10.007983 ° N and 77.246951 ° E, elev. 1780 m, 09 April 2022, Aswathi Anilkumar 5583: (holotype MCH!, isotype KFRI!). Thallus saxicolous, foliose, 3 – 6 cm wide, sub orbicular to orbicular, adnate to tightly adnate. Lobes radiating, sub dichotomous, plane to slightly convex toward the periphery, 1 – 2.5 mm wide, apices discrete, subrotund to truncate; upper surface shiny, smooth, whitish grey towards distal end, dull, rough, brownish grey towards proximal end, irregularly cracked especially towards older lobes, eciliate, epruinose, emaculate; soredia, isidia, and pseudocyphellae are absent; medulla ochre to orange towards the apices; at some parts, especially towards distal region a yellowish lower medulla is visible in addition to upper orange medulla; lower surface black in the centre, paler towards the margin, with dense, black, simple rhizines. Apothecia common, cocoes-type, lecideine, ca. 0.5 – 0.9 mm diam., frequent towards center compared to the margins, laminal, plane to concave. Epihymenium dark brown, 46 – 50 µm high, K + purple, I + blue, KI + blue; hymenium hyaline, 70 − 112 µm high, K−, I + blue, KI−; hypothecium light to dark brown, 87 – 149 µm high; internal stipe brown to brownish orange, inferior part white, K−. Asci 8 − spored, 30.5 − 60.7 × 8.4 − 12.3 µm; ascospores brown, two-celled, oval to ellipsoid, 11 − 14 × 5 − 7 µm. Pycnidia not seen. Chemistry: UV−, Upper cortex K + yellow, C−, KC−, P−, Medulla K− or dirty brown, C−, KC−, P−. Atranorin and terpenes detected by TLC. Additional materials examined (paratypes): INDIA. Kerala: Idukki district, Mathikettan Shola National Park, Sukumaran Kadu, 9.99438 ° N and 77.2535 ° E, elev. 1601 m, on rock, 31 December 2021, Aswathi Anilkumar 5405 (MCH); ibid., Vattapara, 10.004425 ° N and 77.239209 ° E, elev. 1680 m, on rock, 12 April 2022, Aswathi Anilkumar 5818 (MCH). Etymology: Pyxine janakiae is named in honour of Dr. E. K. Janaki Ammal, for her outstanding contributions to Botany. Distribution and ecology: On rocks in montane wet grasslands (elevation of 1460 – 1780 m) of Mathikettan Shola National Park, Idukki, Kerala, India. Found associated with other lichen species such as Buellia quartziana S. R. Singh & D. D. Awasthi (1981: 189), Pertusaria indica Preeti Srivast. & D. D. Awasthi (1993: 212), Parmotrema grayanum (Hue) Hale (1974: 336) and Lecanora oreinoides (Körb.) Hertel & Rambold (1989: 100). The species is currently known from Mathikettan Shola National Park only. Notes: Pyxine janakiae is characterised by its ochre to orange medulla, the absence of vegetative propagules, cocoes-type apothecia and an internal stipe which is brown to brownish orange with a white colouration in lower region. P. janakiae has resemblance with Pyxine himalayensis D. D. Awasthi (1980: 371), Pyxine schechingeri Kalb (1987: 71), Pyxine pungens Zahlbruckner (1928: 210), Pyxine rhodesiaca Vainio ex Lynge (1937: 90) and Pyxine elixii Kalb (1994: 64).	en	Anilkumar, Aswathi, Christy, Arun, Sequeira, Stephen (2025): Pyxine janakiae (Caliciaceae): A new lichen species from the Southern Western Ghats, India.

03C2878AFFCAA17ACE82EAAFFA708324.taxon	description	P. elixii also shows similarity with P. janakiae in having orange medulla, secondary chemistry and both lack vegetative propagules. But, P. elixii has a maculate thallus, white to dirty brown internal stipe, and obscurascence-type apothecia (Kalb, 1994).	en	Anilkumar, Aswathi, Christy, Arun, Sequeira, Stephen (2025): Pyxine janakiae (Caliciaceae): A new lichen species from the Southern Western Ghats, India.
