Scytalidium album is phylogenetically closely related to S. assmuthi, S. aurantiacum, S. rodionovae, S. circinatum, S. terrigenum, and S. tongrenense (Figs 1, 2). Morphologically, S. album is distinguished from S. assmuthi, S. rodionovae, and S. tongrenense by its unknown sexual morph and simultaneous production of arthroconidia and chlamydospore-like cells (Klingström and Beyer 1965; Pavlov et al. 2018; Manawasinghe et al. 2024). Scytalidium album differs from S. terrigenum by its hyaline arthroconidia (Jeong et al. 2025) and from S. circinatum by the shape and size of its chlamydospore-like cells (globose or ellipsoidal, 6.4–14.4 × 4.8–9.6 μm in S. album vs. globose, lobed, or irregular, 4–9 × 3–9 μm in S. circinatum) (Sigler and Wang 1990). Furthermore, S. album differs from S. aurantiacum by its secretion of a pale-yellow pigment (Klingström and Beyer 1965). Additionally, they can be distinguished by their low sequence similarities. Based on a pairwise comparison of ITS and LSU, S. album (ex-type CBS 372.65) differs from S. assmuthi (ex-type PYCC 9837) by 7.4 % (34 / 460 bp, four gaps) in the ITS and 4.2 % (23 / 536 bp, one gap) in the LSU; from S. aurantiacum (ex-type CBS 374.65) by 2.9 % (15 / 521 bp, no gap) in the ITS and 2.5 % (14 / 553 bp, no gap) in the LSU; from S. rodionovae (ex-type 3 C) by 8.6 % (49 / 571 bp, five gaps) in the ITS and 3.7 % (22 / 591 bp, no gap) in the LSU; from S. circinatum (ex-type CBS 654.89) by 6.8 % (49 / 721 bp, five gaps) in the ITS and 5.4 % (67 / 1,234 bp, five gaps) in the LSU; from S. terrigenum (ex-type KNUF- 23-236) by 3.9 % (23 / 580 bp, one gap) in the ITS and 3.3 % (19 / 561 bp, four gaps) in the LSU; and from S. tongrenense (ex-type CGMCC 3.28994) by 6.6 % (36 / 544 bp, six gaps) in the ITS and 2.4 % (14 / 575 bp, one gap) in the LSU.</p><p>This species demonstrates notable inhibitory effects against various wood-decay fungi, revealing promising biocontrol potential (Klingström and Beyer 1965; Klingstrom and Johansson 1973; Cease et al. 1989).

Scytalidium aurantiacum is phylogenetically closely related to S. album, S. assmuthi, S. rodionovae, S. circinatum, S. terrigenum, and S. tongrenense (Figs 1, 2). The distinctions between S. aurantiacum and S. album / S. assmuthi are provided in the notes for S. album and S. assmuthi, respectively. Scytalidium aurantiacum is distinguished from S. rodionovae, S. terrigenum, and S. tongrenense by its unknown sexual morph and hyaline arthroconidia (Klingström and Beyer 1965; Pavlov et al. 2018; Jeong et al. 2025). Scytalidium aurantiacum differs from S. circinatum by its bacilliformia arthroconidia, globose, or ellipsoidal chlamydospore-like cells (Klingström and Beyer 1965; Sigler and Wang 1990). Additionally, based on a pairwise comparison of ITS and LSU, S. aurantiacum (ex-type CBS 374.65) differs from S. rodionovae (ex-type 3 C) by 9 % (49 / 531 bp, five gaps) in the ITS and 9.8 % (88 / 896 bp, 61 gaps) in the LSU; from S. circinatum (ex-type CBS 654.89) by 8.9 % (47 / 530 bp, five gaps) in the ITS and 3.2 % (19 / 590 bp, no gap) in the LSU; from S. terrigenum (ex-type KNUF- 23-236) by 2.5 % (13 / 528 bp, one gap) in the ITS and 8.4 % (822 / 897 bp, 62 gaps) in the LSU; from S. tongrenense (ex-type CGMCC 3.28994) by 6.3 % (33 / 522 bp, six gaps) in the ITS and 8.8 % (79 / 896 bp, 79 gaps) in the LSU.</p><p>This species not only causes blue stain in wood but also exhibits strong antagonistic effects against various wood-decaying fungi, particularly remaining effective at low temperatures (10 ° C) (Klingström and Beyer 1965; Strunz et al. 1972; Cease et al. 1989). Furthermore, the antibiotic metabolite scytalidin produced by S. aurantiacum has demonstrated antifungal activity, making it a candidate for antifungal agent development (Ayer et al. 1993). Dirginčiutė-Volodkienė and Pečiulytė (2011) demonstrated that S. aurantiacum exhibits significant tolerance to copper pollution, indicating its potential as a bioindicator for copper contamination and a candidate species for bioremediation applications.</p></div>	https://treatment.plazi.org/id/D96D5526A55E5C02A7DECE5F4394FC6E	Public Domain	No known copyright restrictions apply.

Scytalidium circinatum is phylogenetically closely related to S. album, S. assmuthi, S. aurantiacum, S. rodionovae, S. terrigenum, and S. tongrenense (Figs 1, 2). The distinctions between S. circinatum and S. album, S. assmuthi, S. aurantiacum, S. rodionovae, S. terrigenum, and S. tongrenense are detailed in the respective notes for S. album, S. assmuthi, S. aurantiacum, and S. rodionovae . Scytalidium circinatum is distinguished from S. terrigenum and S. tongrenense by the shape, size, and aseptate of its chlamydospore-like cells (aseptate, globose, lobed, or irregularly shaped, 4–9 × 3–9 μm in S. circinatum vs. septate, oval-shaped, 5.4–13 × 4.2–8.1 μm in S. terrigenum; and septate, oblong to globose, subcylindrical, guttulate, or irregular, measuring 5–12.5 × 4–6 μm in S. tongrenense) (Jeong et al. 2025). Additionally, based on a pairwise comparison of ITS and LSU, S. circinatum (ex-type CBS 654.89) differs from S. terrigenum (ex-type KNUF- 23-236) by 7.2 % (42 / 583 bp, six gaps) in the ITS and 4 % (24 / 597 bp, two gaps) in the LSU; from S. tongrenense (ex-type CGMCC 3.28994) by 9.1 % (50 / 547 bp, 11 gaps) in the ITS and 3.6 % (22 / 612 bp, one gap) in the LSU.</p><p>This species exhibits capabilities for wood decay and resistance to chemical preservatives.

It has a global distribution and has been isolated from various regions, including the United States, South Africa, Japan, and Bhutan (Robinson et al. 2007). Scytalidium cuboideum produces a red pigment known as draconin red, which exhibits excellent lightfastness, UV resistance, and colorfastness, showing strong potential for applications in textiles, wood coatings, and paper dyeing (Robinson et al. 2014; Gutierrez et al. 2019; Hinsch et al. 2022; Diplock et al. 2023). Notably, although not a common pathogen, it has been isolated from respiratory samples (such as bronchial wash and lung tissue), can grow at 37 ° C, and is susceptible to several antifungal agents (e. g., posaconazole, voriconazole) but resistant to echinocandins and terbinafine, indicating potential pathogenicity (Giraldo et al. 2013; Sy-Cordero et al. 2015).</p></div>	https://treatment.plazi.org/id/96AA98A3200559298F4603393ABC093C	Public Domain	No known copyright restrictions apply.

Morphologically, S. ganodermophthorum differs from S. synnematicum by its production of a sexual morph, arthroconidia, and not producing conidiomata or synnemata (Kang et al. 2010; Crous et al. 2023). Furthermore, based on a pairwise comparison of ITS, S. ganodermophthorum (ex-type UAMH 10320) differs from S. synnematicum (ex-type CCMB 207 / 13) by 9.6 % (50 / 520 bp, 16 gaps) in the ITS. Goh et al. (2015) established S. parasiticum based on morphological characteristics and phylogenetic analyses. However, in this study, S. parasiticum (ex-type AAX 0113) and S. ganodermophthorum (UAMH 10320, H 123, and TPML 97003) clustered in a single subclade with high supported value (100 / 1) (Figs 1, 2). In a comparison of ITS, S. parasiticum (AAX 0113) exhibited 99.8 % (515 / 516 bp, no gap) similarity to S. ganodermophthorum (ex-type UAMH 10320). Moreover, the morphological characteristics between S. parasiticum and S. ganodermophthorum are minor; therefore, we treat S. parasiticum as a synonym of S. ganodermophthorum .</p><p>Scytalidium ganodermophthorum was first discovered in Korea as a pathogenic fungus causing yellow rot in cultivated Ganoderma lucidum (Kang et al. 2010), on which it behaves as an obligate or facultative parasite. While S. ganodermophthorum is a pathogen of G. lucidum, its synonym S. parasiticum has been shown to exhibit antagonistic effects against another Ganoderma species, the oil palm pathogen G. boninense, demonstrating its potential as a biocontrol agent (Goh et al. 2016).</p></div>	https://treatment.plazi.org/id/A7CBDBF8B6165E5E91C90E40481DC7C1	Public Domain	No known copyright restrictions apply.

Agrar. 11 (suppl.): 265 (1957)</p><p>Description and illustration.</p><p>Pesante (1957)</p><p>Notes.</p><p>Scytalidium lignicola is phylogenetically closely related to S. auriculariicola and S. philadelphianum (Figs 1, 2). The distinctions between S. lignicola and S. auriculariicola are provided in the notes for S. auriculariicola . Morphologically, S. lignicola differs from S. philadelphianum by not producing conidia and by having chlamydospore-like cells swollen up to 7 µm wide (Pesante 1957; Crous et al. 2022). Furthermore, based on a pairwise comparison of ITS, S. lignicola (ex-type UAMH 1502) differs from S. philadelphianum (ex-type CPC 40793) in 5.8 % (34 / 580 bp, 14 gaps) in the ITS. Scytalidium lignicola acts as a saprotrophic opportunist in wood, soil, and compost but can shift to a pathogenic mode of life, causing infections in humans (Dickinson et al. 1983; De Gannes et al. 2013). Notably, as a soil-borne pathogen, Scytalidium lignicola often causes cassava black root rot, which is difficult to control and results in significant losses in cassava production (Silva et al. 2013).</p></div>	https://treatment.plazi.org/id/C0A12407A4E85AAA8366BFF88FF9654D	Public Domain	No known copyright restrictions apply.

The distinctions between S. rodionovae and S. album, S. assmuthi, and S. aurantiacum are detailed in the respective notes for S. album, S. assmuthi, and S. aurantiacum . Scytalidium rodionovae is distinguished from S. circinatum, S. terrigenum, and S. tongrenense by its known sexual morph, hyaline, ovoid, and septate chlamydospore-like cells (Sigler and Wang 1990; Jeong et al. 2025). Additionally, based on a pairwise comparison of ITS and LSU, S. rodionovae (ex-type 3 C) differs from S. circinatum (ex-type CBS 654.89) by 4 % (23 / 571 bp, four gaps) in the ITS and 1.1 % (7 / 628 bp, no gap) in the LSU; from S. terrigenum (ex-type KNUF- 23-236) by 7.8 % (44 / 559 bp, six gaps) in the ITS and 3.2 % (42 / 1299 bp, two gaps) in the LSU; from S. tongrenense (ex-type CGMCC 3.28994) by 9.7 % (53 / 548 bp, 11 gaps) in the ITS and 3.7 % (34 / 909 bp, one gap) in the LSU.</p><p>Rodionova et al.

(2018) integrated morphological characteristics and phylogenetic analyses based on molecular data derived from 3 C to reclassify G. candidum into Scytalidium, naming it S. candidum . However, they overlooked the fact that 3 C does not belong to G. candidum . Here, we propose the new species Scytalidium rodionovae to accommodate the species for which 3 C is the ex-type. To date, the genome sequencing of strain 3 C has been completed (Polev et al. 2014). Studies have shown that this strain secretes a variety of enzymes capable of efficiently degrading cellulose, exhibits broad pH adaptability, and holds potential application value in lignocellulosic biomass conversion and green industrial processes (Lapin et al. 2002; Borisova et al. 2015).</p></div>	https://treatment.plazi.org/id/9BAAD4B8D64D525EAB523C9435337257	Public Domain	No known copyright restrictions apply.

However, the name Neocosmospora tuberculata is already occupied (Lee et al. 2025). Therefore, we transferred S. tuberculatum to the genus Neocosmospora as Neocosmospora xizangensis .</p></div>	https://treatment.plazi.org/id/E1D67414F813580A89B1BEFAD63CF91B	Public Domain	No known copyright restrictions apply.
