The species produces definite sclerotia, has single-celled, hyaline ascospores, and lacks a conidial state. The cells of the outer excipulum of the apothecium are globose and appear to be oriented perpendicularly to the apothecial surface (Gamundi and Spinedi 1987), which is a defining character of Sclerotinia species (Kohn 1979). The authors considered S. antarctica most similar to Sclerotinia borealis and suggested that they might represent a distinct genus. Kohn (1979) placed S. borealis in Myriosclerotinia, but this treatment was subsequently rejected (Schumacher and Kohn 1985). DNA sequence data are required to confirm the taxonomic placement of S. antarctica .</p></div>	https://treatment.plazi.org/id/C117AE34C7215A5ABCC7EB945A577E46	Public Domain	No known copyright restrictions apply.

Wang (holotype: S 1 (1), Shenyang Agricultural College Mycological Herbarium) .</p><p>Discussion.</p><p>Sclerotinia asari has a dual history. Kohn (1979) noted that the epithet “ asari ” was used by Whetzel for isolates he collected “ near Asarum . ” However, this name was never published, and these isolates were later considered to belong to Dumontinia tuberosa Kohn (1979) . Sclerotinia asari was later formally described on Asarum heterotropoides (Wang &amp; Wu, 1983) . No DNA sequence data are available for this species, but Kohn et al. (1988) conducted an RFLP comparison and concluded that S. asari is distinct from the three core Sclerotinia species (Kohn et al. 1988). However, it remains impossible to determine how this species fits within Sclerotinia or the broader family without DNA sequence data.</p></div>	https://treatment.plazi.org/id/C43324F523E855D888FF4CACF75624B3	Public Domain	No known copyright restrictions apply.

Senn-Irlet (holotype: BSI 96/32 (ZT)) .</p><p>Discussion.</p><p>Sclerotinia cirsii-spinosissimi was described using phylogenetic and morphological data. In a phylogeny based on the ITS locus, two putatively new taxa were identified and temporarily named Sclerotinia sp. 1 and Sclerotinia sp. 2 (Holst-Jensen et al. 1998). Sclerotinia sp. 2 was later described as S. cirsii-spinosissimi, distinguishable from other Sclerotinia species based on ITS sequences and morphological features, including sclerotial size and the size, shape, and presence of lipid guttules in the ascospores (Senn-Irlet and Peter 2016). Based on ITS phylogenies, Holst-Jensen et al. (1998) and Senn-Irlet and Peter (2016) showed that S. cirsii-spinosissimi groups most closely with Sclerotinia borealis (Senn-Irlet and Peter 2016), which Kohn (1979) considered to belong to Myriosclerotinia but was later regarded as doubtful by Schumacher and Kohn (1985). Baral and Quijada (2020) subsequently introduced the new combination Botrytis cirsii-spinosissimi for this species. This decision was based on morphological characters, namely the presence of host remnants in the sclerotial medulla and vacuolar bodies in the living paraphyses, as well as analysis of ITS sequences (H. O. Baral, personal communication, November 2025). The ITS sequence of the S. cirsii-spinosissimi type strain (GQ 848548.1) shares 98.3–98.7 % BLAST similarity with many Botrytis cinerea sequences, and phylogenetic analyses of ITS data suggest that it is more closely related to Botrytis than to Sclerotinia (H. O. Baral, personal communication, November 2025). The phylogenetic work conducted to date on S. cirsii-spinosissimi has relied solely on ITS sequence data, as this is the only region for which sequences are currently available. Additional gene regions are required to clarify this species’ relationships within Sclerotiniaceae .</p></div>	https://treatment.plazi.org/id/41DE649C2F59587093B2FFEC1B649D4C	Public Domain	No known copyright restrictions apply.

The species has a narrower host range than other Sclerotinia species, primarily infecting ginseng, showing no pathogenicity on Asarum and only mild pathogenicity on soybean (Wang et al. 1995). While Wang et al. (1995) did not clarify whether the cells of the outer excipulum of the apothecium of S. ginseng are globose and oriented perpendicularly to the apothecial surface, all other defining features of Sclerotinia species are present, and the morphological and electrophoretic evidence supports recognition of S. ginseng as an independent species.</p></div>	https://treatment.plazi.org/id/19E07A8488DA50D59968E826A56E8030	Public Domain	No known copyright restrictions apply.

Graf (holotype: Z-ZT 16657) .</p><p>Discussion.</p><p>Sclerotinia glacialis was isolated and described from glacier buttercups ( Ranunculus glacialis) using morphological characters. It was distinguished from the three species accepted by Kohn’s (1979) based on ascospore size (8–10 µm × 22–27 µm in S. glacialis vs. 4–9 µm × 8–20 µm in the other species) and the presence of four-spored asci (vs. eight) (Graf and Schumacher 1995). Although an ITS phylogeny showed S. glacialis clustered with another newly described species, S. nivalis (Senn-Irlet and Peter 2016), the lack of bootstrap support casts doubt on this finding. However, the cells of the ectal excipulum conform to those of Sclerotinia sensu Kohn (1979), supporting S. glacialis as a true Sclerotinia species. Additional phylogenetic work is needed to support its placement in Sclerotinia and to clarify its relationship to other species in the genus.</p></div>	https://treatment.plazi.org/id/8E3147B50916578EAF183411217E6171	Public Domain	No known copyright restrictions apply.

Isolates of this species were originally obtained in Japan and assigned to Sclerotinia intermedia (Tochinai 1958; Saito 1997).

A re-evaluation of isolates collected between 1981 and 1985 confirmed that these represented a separate species, which was named S. nivalis (Saito 1997) . This species was distinguished from the three core Sclerotinia species by its intermediate sclerotial size in culture, binucleate ascospores, molecular mass differences of certain sclerotial proteins, and patterns of esterase isozymes (Saito 1997). The RFLP study by Kohn et al. (1988) which supported the designation of S. sclerotiorum, S. minor, and S. trifoliorum as distinct species, also included an isolate of S. nivalis and showed that S. nivalis and S. asari are distinct from the three core Sclerotinia species.

(1998) identified two putative new taxa in an ITS phylogeny, which were temporarily named Sclerotinia sp. 1 and Sclerotinia sp. 2 . The latter was subsequently described as S. cirsii-spinosissimi by Senn-Irlet and Peter (2016). Later, a report of Sclerotinia sp. 1 infecting lettuce, cabbage, beans, and potatoes in Alaska was published by Winton et al. (2006). This taxon was subsequently referred to as S. subarctica in a publication describing microsatellite markers for the species, and the authors stated that a “ formal species description of S. subarctica is in preparation ” (Winton et al. 2007). However, it appears that this species description was never realised, although multiple publications have since reported infection by S. subarctica in new regions and on new hosts (Clarkson et al. 2010, 2017; Brodal et al. 2016; Leyronas et al. 2018). In light of the widespread and continued use of the provisional name Sclerotinia subarctica, a formal taxonomic revision and valid species description are needed to ensure nomenclatural stability.</p></div>	https://treatment.plazi.org/id/03920E54EDBE5F3095774DE373B78FFF	Public Domain	No known copyright restrictions apply.

Holst-Jensen &amp; T. Schumacher (holotype: University herbarium of Oslo 89 / 106) .</p><p>Discussion.</p><p>Sclerotinia tetraspora was described from Rubus chamaemorus, a species of flowering plant in the rose family (Holst-Jensen and Schumacher 1994). The species was distinguished from other Sclerotinia species based on its four-spored asci and unique RFLP patterns. Cells of the ectal excipulum are described as “ isodiametric to slightly elongate, ” as opposed to globose, but are oriented perpendicular to the surface (Holst-Jensen and Schumacher 1994), meaning that this species meets the basic morphological criteria of Sclerotinia . However, the position of S. tetraspora within Sclerotiniaceae remains uncertain (Holst-Jensen et al. 1998). Based on their ITS phylogeny, Holst-Jensen et al. (1998) noted that S. tetraspora belongs to Sclerotinia sensu lato but cannot be included in Myriosclerotinia or Sclerotinia sensu stricto . Subsequent studies showed that Sclerotinia tetraspora is closely related to S. borealis and S. glacialis (Lorenzini and Zapparoli 2016; Baturo-Ciesniewska et al. 2017). Given that S. borealis and S. glacialis are themselves of uncertain placement, these phylogenies do not conclusively demonstrate that S. tetraspora is a member of Sclerotinia . The taxonomic identity of S. tetraspora cannot be resolved until a more robust phylogeny is produced that better supports its placement.</p></div>	https://treatment.plazi.org/id/FFB1111274C75232AA34312400448F84	Public Domain	No known copyright restrictions apply.

Harada (holotype: HIROSAKI UNI-23933) .</p><p>Discussion.</p><p>Sclerotinia trillii was described from Japan, where it infected Trillium species (Narumi et al. 2001). This species was compared with S. sclerotiorum, S. minor, S. trifoliorum, and S. nivalis and was considered distinct based on its relatively large sclerotia and apothecia, culture appearance, apothecium color, sclerotial protein banding patterns, and its ability to infect Trillium (Narumi et al. 2001) . Pathogenicity trials on Trillium, however, included only S. nivalis vs. S. sclerotiorum, which weakens host specificity as a defining trait. Given the wide host ranges of S. minor and S. trifoliorum, it remains possible that one or both may also be pathogenic on Trillium species. Additionally, Narumi et al. (2001) described S. trillii as producing microconidia on sclerotia and old mycelia, although the functionality of these structures was not addressed. While microconidia have been observed in the three core Sclerotinia species, these do not function as germinating propagules (Kohn 1979). This lack of functional conidia has been accepted as a defining characteristic of Sclerotinia (Whetzel 1945; Kohn 1979). Given the uncertainty surrounding several of the characters used to define S. trillii, it would be prudent to re-evaluate the taxonomic status of this species in future studies.</p></div>	https://treatment.plazi.org/id/C30BF0783C945DA99B535882348A1935	Public Domain	No known copyright restrictions apply.

Sclerotinia verrucispora meets the basic criteria for a Sclerotinia species in that it has definite, tuberoid sclerotia, single-celled, hyaline ascospores, and cells of the apothecial outer excipulum that are globose and oriented perpendicularly to the apothecial surface (Baral 1989). Baral (1989) considered this a distinct species based on the rough ornamentation of the ascospores, a feature not observed in the core species described by Kohn (1979). Additionally, Kohn (1979) described the sclerotial medullae of the core Sclerotinia species as “ textura oblita with strongly gelatinized walls, ” whereas sclerotia of S. verrucispora have loose, thin-walled textura intricata medullae that are “ intercellular with crystals ” and completely free from gel (Baral 1989). The species is mentioned only briefly in the publication describing S. glacialis (Graf and Schumacher 1995), and to our knowledge this is the only subsequent published use of the name S. verrucispora . DNA sequence data will be required to confirm the taxonomic placement of this species.</p></div>	https://treatment.plazi.org/id/F9F5A97DD444525FAFF9560B92290B27	Public Domain	No known copyright restrictions apply.
