The new species is named Hansenula alni because of its specific habitat in exudates of alder trees. This species occurs naturally in the haploid condition. Upon mixing of compatible mating types, conjugation occurs, and up to four hat-shaped spores are produced in zygotes or in diploid cells arising from zygotes. H. alni resembles H. canadensis (syn.: H. wingei) but differs from it in habitat and in ability to grow at 37°C; furthermore, the deoxyribonucleic acid base composition of the former is approximately 1.5 mol% higher than that of the latter. The type strain of H. alni is UCD-FS&T 68-928A (= ATCC 36594 = CBS 6986). Its compatible mating type is UCD-FS&T 68-940 (= ATCC 36595 = CBS 6987)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-29-1-60
