| Abstract: | Two new species ofHeleococcum (a cleistothecial nectrioid genus in the Hypocreaceae) are described and illustrated.Heleococcum alatosporum, isolated from Indonesian soil, is recognized by the production of salmon-colored ascomata, cylindrical asci, and hyaline, small, bicellular ascospores with walls that are verruculose and ornamented with longitudinal ridges.Heleococcum inapertum, isolated from Philippine soil, is characterized by yellow ascomata, clavate asci, and pale yellow, middle-sized, bicellular, verruculose to weakly striate ascospores surrounded with a hyaline sheath. Anamorphs of the new species are included inAcremonium. A key to the accepted species of the genus is provided. |
