Abstract
A new species, Cerinomyces aculeatus, is described and illustrated. The fungus is macroscopically characterized by having resupinate, effused, nongelatinous, and odontoid basidiomes and microscopically by hyphal pegs, dacrymycetaceous Y-shaped basidia and nodose-septate hyphae. Cerinomyces aculeatus differs from all previously described species in the combination of these characteristics. Basidiospores of this fungus are unicellular when liberated but become septate during germination. The monokaryotic mycelia produce an anamorph of Sporothrix sect. Luteoalba in culture. The hyphal septum possesses a dolipore with nonperforated parenthesomes. These characteristics suggest that C. aculeatus should be placed in the Dacrymycetaceae.
