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 View Materials . Fig. 4H–J View Fig .

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 9889 View Materials H, ex-holotype cultures PYCC 9889 View Materials , CBS 18642 View Materials ). 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 View Fig ). 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 View Fig ). 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).
