After one month under the same conditions, conspicuous rings and sediment were present. On YM agar at 17 ° C for 3 days, colonies were creamy-white, butyrous, and emitted a characteristic aroma; the center was slightly raised and produced filaments when lifted with a loop. Pseudohyphae were not formed on cornmeal agar. No ascospores or sexual structures were observed on YM, PDA, V 8, or cornmeal agar after 6 weeks. Ballistoconidia were not produced. Physiological and biochemical characteristics: D-Glucose, sucrose, melibiose, raffinose, melezitose, inulin, soluble starch, L-rhamnose, ethanol, glycerol, galactitol, D-mannitol, D-glucitol, DL-lactic acid, and succinic acid were assimilated. D-Galactose, maltose, cellobiose, and citric acid were assimilated weakly or after a delay. L-Sorbose, trehalose, lactose, L-arabinose, D-arabinose, D-ribose, N-acetyl-D-glucosamine, methanol, erythritol, ribitol, α-methyl-D-glucoside, inositol, and hexadecane were not assimilated. Cadaverine dihydrochloride, L-lysine (weakly), and potassium nitrate (weakly) were utilized as sole nitrogen sources; ammonium sulfate, sodium nitrite, and ethylamine hydrochloride were not utilized. Starch-like compounds were not produced. Growth in vitamin-free medium was weak.

The type strain CGMCC 2.8853 showed significant genetic divergence from its closest phylogenetic neighbors, with sequence disparities of 10.22 % in the D 1 / D 2 domain and 15.66 % in the ITS region, unequivocally supporting its status as a distinct species. Phenotypically, C. basumtsoensis exhibits a distinctive combination of traits, including weak assimilation of D-galactose, delayed assimilation of raffinose and inulin, weak utilization of potassium nitrate and L-lysine, and an inability to assimilate trehalose or ethylamine hydrochloride (Table 4). These characteristics provide a clear phenotypic signature that differentiates it from other described Cyberlindnera species.</p><p>Note: +, positive; –, negative; w, weakly positive; d, delayed; dw, delayed weak; n, not determined.</p></div>	https://treatment.plazi.org/id/DAD9926253C053429E16808DA935371E	Public Domain	No known copyright restrictions apply.

After one month under the same conditions, prominent rings and sediment were present. On YM agar at 17 ° C for three days, colonies were creamy, smooth, glossy, and exhibited surface ridges with serrated margins. Pseudohyphae were not formed on cornmeal agar. No ascospores or sexual structures were observed on YM, PDA, V 8, or cornmeal agar after six weeks. Ballistoconidia were not produced. Physiological and biochemical characteristics: D-Glucose, sucrose, melibiose, D-arabinose, D-ribose, L-rhamnose, D-mannitol, and raffinose (delayed and weak) were assimilated. The following carbon sources were assimilated weakly or after a delay: D-galactose, sorbose, maltose, cellobiose, trehalose, lactose, melezitose, D-xylose, N-acetyl-D-glucosamine, ethanol, glycerol, galactitol, and hexadecane.

The D 1 / D 2 domain sequence of strain CGMCC 2.8854 differs by seven substitutions (1.39 %) from that of M. collariae ATCC MYA- 4666 T, while the ITS region shows 44 mismatches (8.78 %, including 29 substitutions and 15 indels), values that exceed thresholds commonly accepted for species delineation in yeasts. Phenotypically, M. lacustris can be clearly distinguished from its congeners by its unique carbon and nitrogen assimilation profile. Specifically, it assimilates melibiose, L-rhamnose, galactitol (delayed), and hexadecane (delayed), all of which are not utilized by M. collariae or M. swertiae . Conversely, it fails to assimilate α-methyl-D-glucoside, potassium nitrate, or ethylamine hydrochloride, compounds that are utilized by both related species. These consistent phenotypic differences, summarized in Table 3, corroborate the phylogenetic data and firmly support its status as a novel species.</p><p>Note: +, positive; –, negative; w, weakly positive; d, delayed; dw, delayed weak; n, not determined.</p></div>	https://treatment.plazi.org/id/50D39D96BED05ECEA49AD11565272D0A	Public Domain	No known copyright restrictions apply.
