PERITHECIA |
|
Most Hypoxylon taxa have spherical to obovoid perithecia. Long tubular perithecia are usually produced in taxa with more massive stromata. Perithecial mounds are considered taxonomically significant only when extremely conspicuous. Hypoxylon croceum, H. lenormandii, and H. undulatum are easily identified in usually having more than half of the perithecial mounds exposed. |
