Torulaspora gathmanii J. Al-Oboudi, M. Silva, F. Paraíso, M. Jarzyna, Q.K. Langdon, D.A. Opulente, J.P. Sampaio & Hittinger, sp. nov. MB 853979. Fig. 4H–J. Etymology: Torulaspora gathmanii. gath.man’i.i, N.L. gen. n. gathmanii, of Gathman, in honor of Allen C. Gathman, in recognition of his lifelong contributions to fungal genetics and genomics. Typus: USA, Wisconsin, University of Wisconsin-Madison, Lakeshore Preserve, Prairie C, soil, 2016, M. Jarzyna (holotype PYCC 9889H, ex-holotype cultures PYCC 9889, CBS 18642). The holotype is permanently maintained in a metabolically inactive state in the Portuguese Yeast Culture Collection, Caparica, Portugal. The genome of this species was deposited at DDBJ/ENA/GenBank under the accession GCA_030580195. The version described in this paper is v. 1. Description: After 1 wk on YM agar at 25 °C, cultures are smooth, cream-coloured, and butyrous. After 3 d of growth on YM agar at 25 °C, cells are globose (3–5 µm) to sub-globose (4–6 × 3–5 µm) and occur singly or in pairs, and proliferation is by multilateral budding (Fig. 4H). On Dalmau plates after 2 wk at 25 °C, no pseudohyphae nor true hyphae are formed. Sexual reproduction is observed on acetate agar after 7 d at 20 °C, and the cultures appear to be homothallic. Asci are persistent and normally are formed after conjugation involving a cell and its bud. Asci produce one to three, possibly four, smooth and spherical ascospores, measuring 3–4 µm diam. (Fig. 4I, J). The physiological and biochemical profile of the species in shown in Table 1 and Table S5. Habitat and distribution: This species was found in soil, in preserved areas of the University of Wisconsin - Madison, Wisconsin, USA. Additional cultures examined: PYCC 9890 (see Table S1 for details).
