L. Watson and M. J. Dallwitz

Lasiosphaeriaceae

Syn. Tripterosporaceae.

Anamorphic forms occurring (rarely prominent).

Morphology. The fruit-bodies producing asci and ascospores; cupulate, or pear-shaped, or globose (? - “ostiolate or not”, dark, often thick walled, often hairy or ornamented); “dark”; perithecial, or cleistothecial; stromata absent (rarely with a basal subiculum). The asci cylindrical-clavate to clavate; with more or less conspicuous apical thickening (usually with a small apical j- ring); thin walled (not fissitunicate, rarely evanescent). The walls of the asci not staining blue with iodine. The ascospores smooth, or ornamented (occasionally); usually hyaline and brown (with at least one dark brown and one hyaline cell); septate; appendaged (with gelatinous appendages or caudae); without a mucilaginous sheath.

The hyphae without clamp connections. The hyphal walls lamellate, double layered, with both layers electron dense.

Ecology. The fruit-bodies on dead wood. Found in coniferous woodland, in broad-leaved woodland, and in mixed woodland.
