Mycelia 1.7–2.2 µm wide, immersed to superficial, composed of branched, septate, initially hyaline to pale brown, smooth hyphae, later becoming brown to dark brown, finely verruculose or warty-surfaced hyphae. Conidiophores semi-macronematous or micronematous, hyaline, aseptate, or reduced to conidiogenous cells. Conidiogenous cells 4.0–6.9 × 2.8–5.6 µm (x ̄ = 5.6 × 4.2 μm, n = 30), mono- or polytretic, solitary, discrete, globose or clavate, lateral, rarely terminal, pale brown, smooth-walled, with inconspicuous 1–2 conidiogenous loci.

Q. Sun, BR 11-5 - 1, ex-paratype living culture KUNCC 25-20157 .</p><p>Notes.</p><p>The present phylogeny demonstrated that the new strains KUNCC 25-20156 (ex-holotype) and KUNCC 25-20157 (ex-paratype) are phylogenetically situated within the genus Polyschema (Fig. 1). The newly identified species, P. adansoniae-digitatae, has a close relationship with the clade including P. congolense and P. hongheense . Base pair comparisons in the ITS, LSU, and rpb 2 loci between P. adansoniae-digitatae KUNCC 25-20156 (holotype) and P. congolense CBS 542.73 (holotype) showed 10.1 % nucleotide differences (58 / 575 bp, including 27 gaps) in ITS, 2.3 % nucleotide differences (19 / 840 bp, including four gaps) in LSU, and 6.8 % nucleotide differences (52 / 761 bp, no gaps) in rpb 2. Due to the unavailability of the SSU sequence for P. congolense, comparative analyses for this locus could not be conducted. Polyschema adansoniae-digitatae KUNCC 25-20156 and P. hongheense KUNCC 25-20158 showed nucleotide differences of 9.6 % (52 / 544 bp, including 22 gaps) in ITS, 2.3 % (19 / 834 bp, including four gaps) in LSU, 2.8 % (38 / 1344 bp, including 18 gaps) in SSU, and 6.7 % (70 / 1042 bp, including one gap) in rpb 2, respectively.</p><p>Accompanied by phylogenetic evidence, morphological characteristics provide clear distinctions among P. adansoniae-digitatae, P. congolense, and P. hongheense, particularly in terms of conidial features. The conidia of P. adansoniae-digitatae are 2–3 - septate, generally larger, and exhibit more variable shapes, ranging from ellipsoidal to obovoid or oblong, whereas those of P. hongheense are 1–2 - septate (sometimes reaching up to four septa), more uniformly sized, and generally narrower (Table 2). Furthermore, conidiogenous cells of P. adansoniae-digitatae are significantly smaller than those of P. congolense and P. hongheense (Table 2).</p></div>	https://treatment.plazi.org/id/20DF5763FDFF5BCE9491A56F310B1B6E	Public Domain	No known copyright restrictions apply.

Q. Sun, BR 16-5, ex-paratype living culture KUNCC 25-20160 .</p><p>Notes.</p><p>Polyschema radicicola is basal to a subclade containing P. adansoniae-digitatae (KUNCC 25-20156 and KUNCC 25-20157), P. congolense (CBS 542.73), and P. hongheense (KUNCC 25-20158). These species form a subclade and have a close relationship with P. endophytica (COAD 3972) and P. terricola (CBS 301.65). Based on nucleotide comparisons, P. radicicola KUNCC 25-20159 (holotype) differs from P. congolense CBS 542.73 (holotype) in the ITS sequence by 34 / 548 bp (6.2 %, including 14 gaps), in the LSU sequence by 14 / 846 bp (1.7 %, including one gap), and in the rpb 2 sequence by 82 / 768 bp (10.7 %, including three gaps). Polyschema radicicola KUNCC 25-20159 differs from P. hongheense KUNCC 25-20158 by 5.8 % nucleotides in ITS (30 / 518 bp, including nine gaps), 1.4 % nucleotides in LSU (12 / 844 bp, including one gap), 2.3 % nucleotides in SSU (31 / 1336 bp, including nine gaps), and 8.9 % nucleotides in rpb 2 (94 / 1060 bp, including four gaps). Polyschema radicicola KUNCC 25-20159 differs from P. endophytica COAD 3972 (holotype) by 9.4 % nucleotides in ITS (52 / 556 bp, including 28 gaps) and 2.0 % nucleotides in LSU (17 / 849 bp, including four gaps), and differs from P. terricola CBS 301.65 (holotype) by 11.4 % nucleotides in ITS (57 / 501 bp, including 33 gaps), 2.3 % nucleotides in LSU (20 / 852 bp, including seven gaps), and 10.0 % nucleotides in rpb 2 (77 / 769 bp, including three gaps).</p><p>Morphologically, Polyschema radicicola is distinguishable by its colony producing orange pigment (Table 2). Furthermore, P. radicicola exhibits mycelial hyphae that are occasionally narrow, flexuous, and smooth-walled, yet remain capable of generating conidiogenous cells and conidia. Conidia of P. radicicola differ from those of P. terricola (Ellis 1976) by being longer and narrower (20.4–40.9 × 7.5–13.1 µm vs. 15–35 × 13–18 μm), cylindrical, distinctly echinulate at the surface, and transversely 2–5 - septate, lacking vertical septa, whereas P. terricola has transversely 0–3 - septate conidia with sometimes one longitudinal or oblique septum (Ellis 1976). Polyschema congolense (Reisinger and Kiffer 1974) can be distinguished from P. radicicola by having smaller (16–26 × 8–11 μm) and 2–3 - septate conidia, commonly with two septa. Polyschema hongheense differs by having shorter (12.8–36.6 × 7.4–13.6 µm), paler brown, 1–4 - septate conidia, commonly with 1–2 septa and occasionally formed terminally. Polyschema endophytica (Crous et al. 2025) differs by having aseptate, globose, subglobose to ellipsoidal, smooth-walled conidia.</p></div>	https://treatment.plazi.org/id/942E2874E09E5BD390A2297CD53CEC5B	Public Domain	No known copyright restrictions apply.
