摘要：
A new species of Helicascus (H. unilocularis) is described and illustrated from submerged wood collected from aquatic habitat in the Caribbean area in Central America. It is morphologically characterized by unilocular ascostromata combined with a poorly developed pseudostroma and ascospores with a smooth wall and lacking a mucilaginous sheath. Its relationships with other species of Helicascus are discussed based on morphology and 28S and ITS rDNA sequences comparisons. Helicascus thalassioideus is reported for the first time from the Neotropics, and a detailed description of H. thalassioideus is provided.
