Characteristics of ascospores, mitosporic state and pathogenicity of Leptosphaeria, Paraleptosphaeria, Plenodomus and Subplenodomus in vivo.

Genus	Ascospores	Mitosporic state	Pathogenicity
Leptosphaeria	Ascospores 3-septate, (dark) brown	Mitosporic state common, pycnidial cell wall usually directly scleroplectenchymatous, conidia mostly aseptate	Necrotrophic
Paraleptosphaeria	Ascospores 3-5-septate, hyaline to yellow/brown	Mitosporic state rare, pycnidial cell wall directly scleroplectenchymatous, conidia aseptate	Necrotrophic
Plenodomus	Ascospores 3-7-septate, pale yellow to brown	Mitosporic state common, pycnidial cell wall initially pseudoparenchymatous, later scleroplectenchymatous, conidia aseptate	Necrotrophic or plant pathogenic
Subplenodomus	No known sexual state	Mitosporic state common, pycnidial cell wall mainly pseudoparenchymatous, conidia aseptate	Necrotrophic or plant pathogenic
Heterospora	No known sexual state	Mitosporic state common, pycnidial cell wall pseudoparenchymatous, conidia of two types: small aseptate and large septate	Plant pathogenic
