Sexual morph: Pairs of compatible strains, when mixed on CMA at 22 °C for 5 days, develop sparse hyphae with one or more clamps at the septa. Phragmobasidia form within 5–14 days on the apical hyphal cell and intercalary or laterally on the hyphae. Some hyphae grow at an angle after basidial formation, which results in an angular growth pattern. The basidia are polymorphic lageniform (7 x 27 μm) with longitudinal and transverse septa; navicular (10–13 x 19–21 μm) with one to three transverse septa; four-celled globose (13–19 μm) and ovoid with longitudinal to oblique and transverse septa. The globose basidia occur singly, in pairs and in chains. Germination usually occurs within 1 week when 1-month-old basidia in agar blocks are transferred to 2% water agar. Basidiospores are globose (4–11.3 μm) or ovoid to cylindrical (6–10 x 7.5–11.3 μm). The basidiospores are passively released and may bud to form colonies in the agar. Basidiospores may also bud while attached to the basidium. The mating system appears to be unifactorial biallelic, as represented by one strain of mating type A and five strains of mating type a. Mating reactions not observed. These non-mating strains could represent a separate sexual incompatibility factor as part of a multiple allelic system. The mating reaction, on Bacto CMA with additional 2% Bacto agar, results in more extensive hyphal development with masses of yeast cells, which appear to be the result of basidiospore replication.
