Saprobic or pathogenic on stems and leaves of herbaceous or woody plants in terrestrial habitats. Sexual morph: undetermined. Asexual morph: Coelomycetous. Conidiomata pycnidial, immersed to semi-immersed, globose to subglobose, black with one or two distinct ostiole. Ostiole sometimes papillate or with elongated neck. Conidiomata wall composed of 3–5 layers of cells of textura angularis, pale yellowish brown. Conidiogenous cells phialidic, subglobose to short conical. Conidia hyaline, aseptate, oblong to ellipsoidal with two to many guttules (van der Aa and van Kesteren 1979).
Type species: Heterosporicola chenopodii (Westend.) Gruyter et al.,
Notes: Heterosporicola is a legitimate name for Heterospora. Heterosporicola was previously introduced as Phoma sect. Heterospora (Boerema 1997). De Gruyter et al. (2013) raised Heterospora to generic rank and accommodated two species of Phoma sect. Heterospora that cluster in the Leptosphaeriaceae namely H. chenopodii and H. dimorphospora. Other members of Phoma sect. Heterospora clustered in the family Didymellaceae (Aveskamp et al. 2010). Heterosporicola is characterized by globose to subglobose conidiomata, pale yellowish brown conidiomatal wall comprising cells of textura angularis, hyaline, aseptate conidia. Heterosporicola is currently a distinct and well-supported genus in Leptosphaeriaceae.
