Morphological comparison of Linocarpon, Neolinocarpon and Claviformispora.
| Morphology | Linocarpon | Neolinocarpon | Claviformispora |
| (Type: L. pandani) | (Type: N. globosicarpum) | (Type: C. phyllostachydis) | |
| Stromata | Absent | Absent | Solitary or aggregated, comprising elliptical areas and large black areas, with slit-like openings |
| Ascomata | Solitary, superficial, subglobose, comprising black, dome-shaped, raised blistering areas, central ostiole | Solitary, deeply immersed, oval to globose, with central raised, dark, shiny papilla, central ostiole with periphyses | Solitary or aggregated, deeply immersed, subglobose, slightly raised blistering areas, central ostiole with periphyses |
| Peridium | Textura angularis | Textura angularis | Textura angularis |
| Hamathecium | Hyaline, septate paraphyses, longer than asci | Hyaline, septate paraphyses, longer than asci | Hyaline, septate paraphyses, longer than asci |
| Asci | Cylindrical, unitunicate, a small non-amyloid apical ring | Long cylindrical, pedicellate, unitunicate, an oblong to wedge-shaped, refractive, apical ring and some with a refractive circular body below | Cylindrical to cylindric-clavate, unitunicate, pedicellate, doughnut-shaped, refractive, J- apical ring |
| Ascospores | Filiform, aseptate, hyaline or pale-yellowish in mass, parallel or spiral, with appendage and refringent septum-like bands or absent | Filiform, aseptate, hyaline or pale-yellowish in mass, parallel or spiral, with apical appendages and refringent bands or absent | Clavate, thin pedicellate, aseptate, hyaline, parallel, no appendage and refringent band |
| Asexual morph | Only found in L. appendiculatum and L. elaeidis, conidiophore arising from the aerial mycelium, conidiogenous cells phialidic, smooth, translucent brown, conidia clavate to fusiform, straight or slightly curved or slightly sinuous, unicellular, smooth, colourless | Undetermined | Undetermined |
| Others | Colonies on MEA and PDA growing slowly | Colonies on MEA growing slowly. Ascospores on MEA produced appressoria-like structures at each tip of germ tube, only found in N. rachidis | Colonies on PDA grow faster |
