These two fungi represent two genera based on the great phylogenetic distance between them and the distinct pattern of conidiogenesis; while D. minimus shows a Chrysosporium - like asexual morph with thallic conidia, Di. rosea displays a mixture of blastic and thallic conidia arising in acropetal, sometimes basipetal, chains directly from the hyphae (Tanney et al. 2015). The asexual morph of D. minimus resembles that of Amaurascopsis (As.) perforata (Guarro et al. 1992 a), Polytolypa (P.) hystricis (Scott et al. 1993), and Pseudoamaurascopsis (Pd.) spiralis (Torres-Garcia et al. 2023). These three species represent an incertae sedis lineage in Onygenales, defined as clade X by Torres-Garcia et al. (2023). These species are characterized by the production of Chrysosporium - like thallic, terminal, and intercalary, smooth-walled or tuberculate conidia. Deilomyces minimus can be distinguished from As. perforata by smaller terminal conidia (3–4.5 × 2.5–3 µm vs. (3) 4–6.5 (7.5) × 2.5–4.5 µm) (Guarro et al. 1992 a), from Pd. spiralis by shorter intercalary conidia [5.5–8.5 (– 10.5) µm long vs. 7–15 (– 22.5) µm long] (Torres-Garcia et al. 2023), and from P. hystricis by the conidial ornamentation (smooth to tuberculate vs. smooth) (Scott et al. 1993). In addition, the sexual morph of D. minimus resembles those of the phylogenetically distant species of the family Neoarthropsidaceae, Albidomyces (Al.) albicans and Neoarthropsis (Ne.) sexualis . These species produce gymnothecial ascomata composed of a conspicuous network of hyaline to pale yellow and smooth hyphae, subglobose to pyriform, evanescent asci, and globose or subglobose ascospores. Deilomyces minimus can be distinguished from Ne. sexualis by smaller ascomata and thinner peridial hyphae (150–550 µm vs. 365–810 µm diam., and 1.5–2 µm vs. 3–4 µm wide, respectively), and differs from Al. albicans by smaller asci and ascospores (4.5–6 × 4–5 µm vs. 8–11 × 11–17 µm, and 2.5 × 1.5–2.5 µm vs. 3–5 × 3–4.5 µm, respectively). Moreover, the ascospores of D. minimus are smooth, while those of Ne. sexualis and Al. albicans are punctate and punctate to reticulate, respectively (Torres-Garcia et al. 2023).</p></div>	https://treatment.plazi.org/id/60309B22B24257AA96C5291380F88D23	Public Domain	No known copyright restrictions apply.

Microscopically, the three species produce the asexual morph, which is characterized by fertile hyphae that give rise to arthroconidia randomly. The morphological differences between their asexual morphs are the following: Gd. petalosporus displays buff or brown arthroconidia of 2.1–11.9 × 1.4–5.6 µm (Orr et al. 1977), Gd. alboluteus produces hyaline arthroconidia of 2.5–9 × 2.5–3 µm, and in Gd. boliviensis, they are also hyaline but slightly smaller (2–7 × 2–2.5 µm) (Guarro et al. 1992 b). Another difference is the lack of racket hyphae in the latter species, which are present in Gd. petalosporus and Gd. alboluteus . In addition, Gd. petalosporus and Gd. boliviensis produce sexual morphs in culture. Although we have not observed the sexual morph for Gd. alboluteus in any of the media tested, the great phylogenetic distance to other species of the genus confirms it as a novel species.</p></div>	https://treatment.plazi.org/id/9AD9FE9B521F58D48C485522DAE3D345	Public Domain	No known copyright restrictions apply.

The three species are characterized by the production of fertile hyphae that produce arthroconidia randomly. The morphological differences between their asexual morphs are subtle, but M. parafilamentosa shows conspicuously sinuous or contorted fertile hyphae, while in M. filamentosa, they are straight and rarely slightly sinuous (Sigler et al. 2002; Rodríguez-Andrade et al. 2021). Their sexual morphs display gymnothecia with short and long appendages, subglobose asci, and reticulate, subglobose ascospores. Malbranchea parafilamentosa and M. filamentosa are characterized by being heterothallic and producing yellow mass ascospores. These species can be distinguished by the width of the peridial hyphae (2.5–4 (– 4.5) µm and 4.5–6 µm) and the length of the long peridial appendages (200–560 µm and 100–290 µm) (Sigler et al. 2002). Although the lengths of the peridial appendages overlap between M. parafilamentosa and M. thaxteri (200–560 µm and 250–540 µm), the latter species is characterized by being homothallic and producing hyaline ascospores (Kuehn 1955; Orr and Kuehn 1971).</p><p>Of note is that our phylogenetic analyses show that the strains CBS 198.92 and CBS 146932 (Figs 2, 3), labeled as Malbranchea setosa and Malbranchea stricta, respectively, are genetically identical to M. filamentosa (UAMH 4097) (Sigler et al. 2002). However, the authors who sent the specimen to the CBS collection never formally described M. setosa, so this name should be deemed invalid, and M. stricta should be considered a synonym.</p></div>	https://treatment.plazi.org/id/C258B588FEF6566486FA9D03CFBA416E	Public Domain	No known copyright restrictions apply.

Microscopically, the three species produce the characteristic sinuous fertile hyphae of Malbranchea but differ in arthroconidia length, M. sedimenticola [(2.5 –) 4.5–5.5 (– 7.5) µm], M. albolutea [(1.5 –) 2–5 (– 6.5) µm] (Sigler and Carmichael 1976), and M. sinuata (1.5–3 µm) (Torres-Garcia et al. 2023). In addition, only M. sedimenticola and M. albolutea produce the sexual morph, resembling that of the phylogenetically distant species M. thaxteri . The ascomatal peridium consists of yellow to brownish-orange, asperulate hyphae that produce short, spine-like appendages and long, straight to uncinate appendages, subglobose asci, and globose ascospores of 2.5–3 µm diam. Although the sexual morphs of M. sedimenticola and M. albolutea are morphologically similar, they can be distinguished from M. thaxteri by showing longer appendages (500–850 µm and 400–800 µm vs. 252–542 µm, respectively) and smooth to slightly echinulate ascospores under a bright field microscope (Sigler and Carmichael 1976), while M. thaxteri ascospores are echinulate-reticulate.</p><p>It is worth mentioning that the strain CBS 319.61 was formerly identified as M. thaxteri, probably based on ascomata morphology. Although this strain remained sterile throughout the culture media assessed in this study, our phylogenetic analyses support the classification of CBS 319.61 as M. sedimenticola (Figs 2, 3).</p></div>	https://treatment.plazi.org/id/D566DC646B985C6D9A4680EBCD554333	Public Domain	No known copyright restrictions apply.

The three species produce an asexual morph consisting of hyaline and smooth-walled enteroarthric conidia. However, they differ in conidia disposition and size, with M. longispora showing straight chains of larger conidia (4–24 × 1–5.5 µm) (Crous et al. 2013), M. seminuda displaying straight chains of medium-size conidia (4 –) 12–13 (– 14.5) × 2.5–3 µm, and M. multiseptata producing straight and sinuous chains of smaller conidia (3–9 × 1.5–2 µm) (Rodríguez-Andrade et al. 2021). In addition, only M. seminuda and M. longispora produce sexual morphs, which differ in the peridium morphology; while the former species shows a subtle network of hyaline and verruculose to verrucose hyphae, M. longispora displays a conspicuous network of pale yellow to orange-brown, thick-walled, tuberculate hyphae (Crous et al. 2013). Other phylogenetically distant species with ascomata morphologically similar to those of M. seminuda are M. concentrica and M. kuehnii . The three species can be distinguished by the ornamentation pattern of the peridial hyphae, being verrucose in M. seminuda and M. kuehnii but smooth-walled in M. concentrica (Solé et al. 2002) . Malbranchea seminuda differs from M. kuehnii in the colour of the ascospores (pale yellow vs. hyaline, respectively) and colonies on PDA (greenish-yellow vs. brown, respectively) (Solé et al. 2002).</p></div>	https://treatment.plazi.org/id/84078856EA015B2D80A295BA4FC19A09	Public Domain	No known copyright restrictions apply.

Macroscopically these species are characterized by the production of colonies in shades of yellow and orange, with M. ostraviensis being characterized by the production of a reddish diffusible pigment on MEA, PDA, and PCA that has not been observed in the other species. Regarding the reproductive structures, M. sexualis is characterized by exclusively producing the sexual morph, while M. phuphaphetensis is only known by its asexual morph (Preedanon et al. 2023). On the other hand, M. gymnoascoides, M. ostraviensis, and M. umbrina produce both sexual and asexual morphs. The species that display sexual morph produce gymnothecia with similar features (i. e., yellow to brownish orange, asperulate peridial hyphae with short spine-like appendages and long appendages, globose to pyriform asci, and globose ascospores), but can be distinguished by the length of the peridial appendages and ascospore ornamentation. Malbranchea umbrina displays the shortest appendages (5–72 µm) and reticulate ascospores (Hubka et al. 2013), M. ostraviensis displays the longest appendages (350–600 µm) and smooth (reticulate with a central depression under SEM) ascospores (Hubka et al. 2013), and both M. sexualis and M. gymnoascoides produce appendages of overlapping length (150–340 µm vs. 250–400 µm, respectively; Rodríguez-Andrade et al. 2021), but differ in ascospore ornamentation. While the ascospores in M. gymnoascoides are smooth-walled (Rodríguez-Andrade et al. 2021), those of M. sexualis are smooth to slightly echinulate (reticulate under SEM). Although we have not observed the asexual morph for M. sexualis in any of the media tested, the great phylogenetic distance and the morphological characters of the sexual morph confirm it as a novel species.</p></div>	https://treatment.plazi.org/id/B3D0C136EC33524DB5D54E2D8E0E268A	Public Domain	No known copyright restrictions apply.
