Saprobic in marine habitats: After 3 days of growth at 25°C in 5% ME the cells are ellipsoidal to elongate or globose, 2.0–3.43.4–5.4 µm. Cells may be budding on short pedicels and a blunt apical bud scar may be present on the single cells. The streak culture is glossy, cream-colored, butyrous, mucoid, smooth, ﬂat or slightly raised with entire margins after 1-month growth on 5% ME agar at 25°C. Pseudohyphae are not present on Dalmau plate culture on CM agar after 1-week at17°C. Ballistoconidia were not observed. For the results of the physiological tests, see Fell et al. (2015).

Description based on Fell et al. (2011) and Liu et al. (2015).

Type strain, CBS 10870 (NRRL Y-48462) was isolated in the mangroves in Chatman Bend (2°410N, 85°10W) in the Florida Everglades National Park on 10/23/1996.

NOTES: Fell et al. (2015) in a study of mangrove yeasts in the tributaries of the Florida Everglades National Park, USA isolated five new yeasts at different locations, one of which was a Cryptococcus species: C. mangalensis. Subsequently this species has been referred to Papiliotrema by Liu et al. (2015). The genus Papiliotrema is emended to accommodate a well–supported monophyletic clade containing teleomorphic Papiliotrema and Auriculibuller species (Liu et al. 2015) as well as anamorphic yeasts including 16 Cryptococcus and three Bullera species. The characteristic features of the genus is: basidiocarps, if present, minute, ca. 0.5 mm in diameter. Dikaryotic hyphae with clamp connections and haustorial branches. Basidia cylindrical and transversely septate. Cultures pale to brownish yellow. Pseudohyphae and true hyphae may be present. Budding cells present. Ballistoconidia may be present. Sexual reproduction observed in some species. Fermentation absent. Nitrate not utilised. Major CoQ system CoQ–10. Chang et al. (2008) isolated another marine Cryptococcus, C. keelungensis from the surface microlayer at Keelung, north–east Taiwan. This species has recently been referred to the genus Solicoccozyma by Liu et al. (2015) in a major phylogenetic re–assessment of basidiomycete yeasts. Chang et al. (2008) isolated another marine Cryptococcus, C. keelungensis from the surface microlayer at Keelung, north–east Taiwan.
