Cochet	<div><p>Arthrographis G. Cochet</p><p>Notes.</p><p>The genus Arthrographis was established by Cochet (1939), with A. langeronii G. Cochet as the type species. Due to a lack of a Latin diagnosis, it did not conform to the International Code of Botanical Nomenclature (ICBN), so it was regarded as invalid (Giraldo et al. 2014; Li et al. 2022). Later, based on morphological characteristics, Sigler and Carmichael (1976) introduced Arthrographis kalrae (basionym: Oididendron kalrae R. P. Tewari &amp; Macph.) and A. cuboidea (basionym: Scytalidium cuboideum (Sacc. &amp; Ellis) Sigler &amp; Kang) and validated the genus name (Sigler and Carmichael 1976). The asexual morph of Arthrographis species was characterized by a slow growth rate and by the presence of cylindrical arthroconidia released schizolytically from dendritic conidiophores (Sigler and Carmichael 1976; Giraldo et al. 2014). Based on multi-gene phylogeny and morphological characteristics, four new species, A. chlamydospora A. Giraldo, Deanna A. Sutton, Cano &amp; Madrid, A. curvata A. Giraldo, Gené, Deanna A. Sutton &amp; Cano, A. globosa A. Giraldo, Deanna A. Sutton, Cano &amp; Guarro, and A. longispora A. Giraldo, Deanna A. Sutton, Cano &amp; Guarro, were proposed by Giraldo et al. (2014). Recently, A. grakistii Giraldo López &amp; Hern. - Restr. was reported as a new species by Hernández-Restrepo et al. (2020). Arthrographis multiformispora Xin Li, Y. F. Han &amp; Z. Q. Liang was introduced by Li et al. (2022), while some species were transferred to other genera (Kang et al. 2010; Giraldo et al. 2014). Currently, the genus Arthrographis includes 11 species in Index Fungorum (2025) (published on the Internet at http://www.indexfungorum.org, The Royal Botanic Gardens, Kew. [Retrieved 16 March 2026]).</p></div>	https://treatment.plazi.org/id/BC8B01A64F695ED1809C95EF708E469C	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

Arthrographis longispora has cylindrical arthroconidia with truncate or rounded ends (Giraldo et al. 2014).

The sexual morph of Coniochaeta is characterized by superficial or semi-immersed ascomata, cylindrical, clavate, subglobose, or globose asci, and narrowly ellipsoid to fusoid, broadly ellipsoidal to globose ascospores (García et al. 2006; Silva et al. 2023). The asexual morph of Coniochaeta is characterized by phialides with very short lateral necks, periclinal wall thickening, and flaring collarettes (Gams 2000; Weber 2002; Silva et al. 2023). Meanwhile, the genus Coniochaeta has various shapes of conidia, such as ellipsoidal to cylindrical, ellipsoid, ellipsoidal, cylindrical or curved, and bacilliform to allantoid (Arnold et al. 2021; Kabtani et al. 2022; Silva et al. 2023; Crous et al. 2025).

However, the new species differed from these three species in having conidiogenous cells mostly flexuous at the apex, abundant chlamydospores (2.5–10.0 μm diam.), and rare yeast-like cells. The new species can be distinguished from C. fodinicola, which has rare chlamydospores (7–8 μm diam.), abundant yeast-like cells, and no flexuous conidiogenous cells at the apex (Vázquez-Campos et al. 2014). Moreover, C. fodinicola has globose to subglobose perithecia and a mycelial swirl, but these two characteristics were not observed in the three strains of the new species. To date, the morphological descriptions of two species, C. queenslandica and C. australiensis, are unavailable, so it is impossible to compare them with the new species in terms of morphological characteristics in this paper (Tan 2023).

Meanwhile, the family has arthrographis - like or trichosporiella - like asexual morphs (Giraldo et al. 2014). Members of this family are widely distributed, such as in America, Canada, China, India, Kenya, and Tanzania, and have been found in air, compost, dung, marine sediments, soil, and wood, and from opportunistic infections in humans (Malloch and Cain 1971; Giraldo et al. 2014; Li et al. 2022). Giraldo et al.

The genus Rhexothecium has sexual and asexual morphs, but the genus Eremomyces only has the sexual morph (Malloch and Cain 1971; Samson and Mouchacca 1975). A few species of the genus Arthrographis have both sexual and asexual morphs, such as Arthrographis curvata A. Giraldo, Gené, Deanna A.

Spores globose, abundant, rough-walled, hyaline, with pyramidal on the surface, 3.0–4.5 μm (av. 3.82 μm, n = 30), arising mostly directly from hyphae or a few from tips of hyphae enlarged cells, falling off at maturity. Zygospores unknown.

Phylogenetically, the three strains (GZUIFR 25.271, GZUIFR 25.272, and GZUIFR 25.273) can apparently be distinguished from S. minutus, S. aspiralis, and Mycoëmilia scoparia in Spiromycetaceae (Spiromycetales) and clustered in a single clade with a high support value (100 % MLBS and 1.00 BYPP; Fig. 1). In the morphological characteristics, the three strains of S. sinensis have globose spores with pyramidal projections on the surface, arising directly from hyphae or enlarged cells, and ovoid chlamydospores, without zygospores. Spiromyces sinensis differed from S. minutus by producing ovoid and spinose mitospores, with globose zygospores, and without chlamydospores (Benjamin 1963; O’Donnell et al. 1998). Spiromyces sinensis differed from S. aspiralis in its presence of subglobose and warted mitospores, and absence of chlamydospores and zygospores (O’Donnell et al. 1998). Spiromyces sinensis can be distinguished from Mycoëmilia scoparia by its fusiform spores, spherical zygospores, and absence of chlamydospores (Kurihara et al. 2004). Therefore, S. sinensis is introduced as a new species.</p></div>	https://treatment.plazi.org/id/B2269A5314B6561D90FB41B453D0382D	Public Domain	No known copyright restrictions apply.

K. Benj. as the type genus. Species of Spiromycetaceae are characterized by sessile or stalked sporocladia, and sporocladia produce several pedicellate merosporangia by budding (Doweld 2014). Recently, only two genera have been listed in this family, comprising Mycoëmilia Kurihara, Degawa &amp; Tokum. and Spiromyces R. K. Benj. (the type genus) (Ri and Degawa 2025). Mycoëmilia was introduced by Kurihara et al. (2004) and was initially accommodated in Kickxellales based on morphology, with the type species Mycoëmilia scoparia Kurihara, Degawa &amp; Tokum. Later, based on LSU and SSU sequence analysis, Chuang et al. (2017) revealed that members of Mycoëmilia and Spiromyces formed a sister clade in the phylogenetic tree. Subsequently, Reynolds et al. (2023) found that Mycoëmilia and Spiromyces were placed in a clade of Spiromycetales, excluding Kickxellales, by multi-gene phylogenetic analysis. Hence, these two genera are accepted in Spiromycetaceae, Spiromycetales. Species of Spiromycetaceae (Spiromycetales) are commonly known as M. scoparia, S. minutus, and S. aspiralis .</p></div>	https://treatment.plazi.org/id/BF8DFEBCAFBB5E6A919DEB7C154122B0	Public Domain	No known copyright restrictions apply.
