B32C87C0FFC4FFB3FF5AF844FDEB0340.taxon	type_taxon	Type species: Geotrichum candidum Link, Mag. Gesell. Naturf. Freunde, Berlin 3 (1 – 2): 17 (1809) Notes: Geotrichum is distinguished by the features of arthroconidia, which are released in a random sequence, and septal walls that contain micropores (De Hoog et al. 2004). Geotrichum candidum has been found in a range of moist environments, such as soil, plants, dairy products (cheese, cream, milk), digestive tracts of humans and animals, and organic materials in water. The genus Geotrichum currently encompasses 15 species (Zhu et al. 2024). Geotrichum candidum strains have been used in the dairy industry to provide typical cheese flavors (Hemme et al. 1982). Additionally, Geotrichum strains have shown a propensity for biofilm formation (Kamilari et al. 2023). The sexual form of Geotrichum is referred to as Dipodascus, and its asci are multi-spored, usually comprising eight to over one hundred ascospores (de Hoog & Smith 2011). Nonetheless, Nagahama et al. (2008) amended Geotrichum (= Dipodascus) to include four ascospores species. The phylogeny of Geotrichum has been revised by accepting the genera Dipodascus, Galactomyces, and Saprochaete (Zhu et al. 2024). The phylogram of known Geotrichum and our new isolates are presented in Figure 2.	en	Yang, Erfu, Karunarathna, Samantha C., Shao, Shicheng, Han, Lisu, Samarakoon, Milan C., Elgorban, Abdallah M., Chiu, Chuni, Tibpromma, Saowaluck, Promputtha, Itthayakorn (2025): Additions to Termitomyces aurantiacus growing termite comb-associated fungi.

B32C87C0FFC3FFB2FF5AF91CFD4003FC.taxon	materials_examined	Material examined: China, Yunnan Province, Xishuangbanna Tropical Botanical Garden, isolated from active termite fungus gardens, 20 July 2022, E. F. Yang, P, P- 1 (HKAS 129047, holotype), ex-type, KUNCC 22 - 12514. GenBank numbers, KUNCC 22 - 12514 = LSU: PP 915829, ITS: PP 915822. ZHKUCC 22 - 0291 = LSU: PP 915830, ITS: PP 915823. Notes: Based on morphological comparisons, our isolate resembles the genus Geotrichum (Figure 3), producing cylindrical to rectangular and catenate arthroconidia (Zhu et al. 2024). The results of BLASTn searches of LSU (D 1 / D 2) show around 99 % similarity to that of Geotrichum europaeum (JX 17 A 04, ZJ 02 A 01, CBS 866.68) and Ge. pseudocandidum (CBS 11392, 398 R- 4); while ITS only shows 93 – 94 % similarity to that of Geotrichum candidum (HNNU 0034, FJAT- 32266), Ge. geotrichum (UBOCC-A- 101170), Ge. pseudocandidum (CBS 626.83, MVGY- 37 - 2) and Geotrichum sp. (UFMG-CM-Y 2816). Moreover, the combined D 1 / D 2 and ITS multi-gene phylogenetic tree shows that our Geotrichum isolates (KUNCC 22 - 12514 = ZHKUCC 22 - 0291) are sister to Ge. pseudocandidum (CBS 10073, CBS 626.83, CBS 820.71, 398 R- 4), with 86 % (ML) and 1.00 (BI) at neighboring branches (Figure 2). Here we introduce Geotrichum xishuangbannaensis sp. nov., the first known species in this genus Geotrichum associated with the fungus gardens of fungus-growing termites.	en	Yang, Erfu, Karunarathna, Samantha C., Shao, Shicheng, Han, Lisu, Samarakoon, Milan C., Elgorban, Abdallah M., Chiu, Chuni, Tibpromma, Saowaluck, Promputtha, Itthayakorn (2025): Additions to Termitomyces aurantiacus growing termite comb-associated fungi.

B32C87C0FFC1FFB1FF5AFF06FC6D03FC.taxon	type_taxon	Type species: Paecilomyces variotii Bainier, Bull. Soc. Mycol. France 23: 27 (1907) Notes: There are 64 species of Paecilomyces (= Byssochlamys) that have been listed in Species Fungorum (https: // www. speciesfungorum. org /, accessed 15 February 2025); however, molecular sequences are accessible for only 13 species (Spetik et al. 2022). Some sexual Paecilomyces species, previously identified as Byssochlamys, are characterized by eight hyaline to brown, ellipsoidal to obovoid ascospores accommodated in cylindrical to irregular asci (Spetik et al. 2022). In addition, Paecilomyces is an asexually variable genus with high diversity in conidial shape and size; conidia often catenated, basocatenate, ellipsoidal to subfusiform, one-celled, smooth, brown to yellow brown (Samson et al. 2009). Paecilomyces strains were often isolated from indoor environments, soils, plants, animals, and foodstuffs, and several strains of Paecilomyces have been recognized as human pathogens (Urquhart & Idnurm 2023). Paecilomyces species are also known as thermotolerant fungi because some sexual ascospores can withstand temperatures up to 85 ° C, and conidia can survive over 22 minutes at 60 ° C (Urquhart & Idnurm 2023). Paecilomyces may develop in low-oxygen environments and, in the presence of preservatives, produce the mycotoxin viriditoxin. Therefore, Paecilomyces species are frequent food contaminants in heat-treated foods and beverages (Urquhart & Idnurm 2023). The phylogram of Paecilomyces is presented in Figure 4.	en	Yang, Erfu, Karunarathna, Samantha C., Shao, Shicheng, Han, Lisu, Samarakoon, Milan C., Elgorban, Abdallah M., Chiu, Chuni, Tibpromma, Saowaluck, Promputtha, Itthayakorn (2025): Additions to Termitomyces aurantiacus growing termite comb-associated fungi.

F. Yang, C 2, (HKAS 129051), living culture KUNCC 22 - 12517. GenBank numbers, ITS: PP 915824, tub 2: PP 918923. Notes: The BLASTn searches of ITS, LSU, and tub 2 of our isolate KUNCC 22 - 12517 show a 99 – 100 % similarity to Paecilomyces formosus (CBS 296.93, CBS 990.73 B, DTO 45 H 8, FRR 3793, WGS 11736). The colonies in PDA share similar morphology with previously reported Paecilomyces formosus (strain IG 03) by having yellow-brown under naturally reflected light and a rough surface (Bulla et al. 2017). Also, the micro-morphology of our isolate well fits the general concept of Paecilomyces species (Figure 5), with high diversity in conidial shape and size, featured by catenated, basocatenate, ellipsoidal to subfusiform, brown to yellow-brown conidia (Samson et al. 2009). In addition, the phylogram of combined ITS and tub 2 sequences indicated that our isolate KUNCC 22 - 12517 was allied to Paecilomyces formosus strains (CBS 296.93, CBS 990.73 B). Therefore, we report Paecilomyces formosus KUNCC 22 - 12517 from termite fungus gardens for the first time.	en	Yang, Erfu, Karunarathna, Samantha C., Shao, Shicheng, Han, Lisu, Samarakoon, Milan C., Elgorban, Abdallah M., Chiu, Chuni, Tibpromma, Saowaluck, Promputtha, Itthayakorn (2025): Additions to Termitomyces aurantiacus growing termite comb-associated fungi.

B32C87C0FFCCFFBAFF5AFF06FCF60563.taxon	type_taxon	Type species: Pseudallescheria shearii Negroni & I. Fisch. 1944 Notes: Pseudallescheria (Microascaceae) are usually polymorphic; the sexual state is defined by closed, globose ascomata (cleistothecia) surrounded by a peridium of epidermoid texture, the asci are widely club-shaped or spherical and ephemeral, containing ellipsoidal or fusiform ascospores that range from hyaline to pale brown (Gilgado et al. 2007). In addition, Pseudallescheria can exhibit two types of asexual forms. Scedosporium is identified by cylindrical, hyaline conidiogenous cells developed from undifferentiated hyphae, producing obovoidal and sticky conidia (Gilgado et al. 2007); Graphium is identified by substantial, synnemaous, upright hyphal bundles culminating in a dense cluster of conidiogenous cells and conidia are produced from short extensions of these cells with annellidic development (Abrantes et al. 2021). Sometimes, three morphs can be observed in the same culture. They are associated with diverse ecological niches, primarily including soils and streams polluted with aliphatic and aromatic chemicals, cattle dung, and sewage (Abrantes et al. 2021). More importantly, Scedosporium species such as S. apiospermum, S. aurantiacum, S. prolificans, and Pseudallescheria boydii are common human pathogens, Scedosporium infections result in many clinical manifestations, including osteomyelitis, keratitis, lymphocutaneous infection, and sinusitis (Lu et al. 2011, Abrantes et al. 2021). In addition, the phylogram of Pseudallescheria is presented in Figure 9.	en	Yang, Erfu, Karunarathna, Samantha C., Shao, Shicheng, Han, Lisu, Samarakoon, Milan C., Elgorban, Abdallah M., Chiu, Chuni, Tibpromma, Saowaluck, Promputtha, Itthayakorn (2025): Additions to Termitomyces aurantiacus growing termite comb-associated fungi.

B32C87C0FFCCFFBAFF5AFF06FCF60563.taxon	materials_examined	Material examined: China, Yunnan Province, Xishuangbanna Tropical Botanical Garden, 20 July 2022, E. F. Yang, C 1 (HKAS 129050) living culture KUNCC 22 - 12515, KUNCC 23 - 13359. GenBank numbers, KUNCC 22 - 12515 = LSU: PP 911541, ITS: PP 915827, tub 2: PP 918926. KUNCC 23 - 13359 = LSU: PP 911542, ITS: PP 915828, tub 2: PP 918927. Notes: Our isolates produced both asexual morph and sexual morph in PDA media, and the morphological characteristics match the concept of Scedosporium and Pseudallescheria (Figure 10), producing hyaline asci filled with eight fusiform, one-celled, pale brown ascospores and enteroblastic, one-celled, solitary, hyaline to sub-hyaline, ovoid to subglobose conidia (De Hoog et al. 2000, Lu et al. 2011, Abrantes et al. 2021). According to results from BLASTn searches, ITS and LSU genes of our isolates share 98 – 99 % base pair similarities with Pseudallescheria ellipsoidea (LMA 40407486), Pseudallescheria angusta (CBS 254.72) and Scedosporium boydii (CBS: 127829, DMic 083389, DMic 165279); while the tub 2 gene only showed 98 – 99 % similarities with Pseudallescheria angusta (CBS 116894, CBS 108.54, CBS 106.53). In addition, the phylogram also indicated that our isolates (KUNCC 22 - 12515, 23 - 13359) were specifically placed in the clade of Pseudallescheria angusta (Figure 9). Therefore, we illustrate a new collection record of P. angusta from termite fungus gardens.	en	Yang, Erfu, Karunarathna, Samantha C., Shao, Shicheng, Han, Lisu, Samarakoon, Milan C., Elgorban, Abdallah M., Chiu, Chuni, Tibpromma, Saowaluck, Promputtha, Itthayakorn (2025): Additions to Termitomyces aurantiacus growing termite comb-associated fungi.
