Peltaster fructicola and Geastrumia polystigmatis were associated with the ramose mycelial type. A fungus similar to P. fructicola, but with smaller pycnothyria and conidia, was associated with the punctate mycelial type. The diffuse fuliginous mycelial type was caused by Leptodontium elatius. Fungi that fit the classical morphological description of G. pomigena were not observed. Pycnothyria of P. fructicola developed on overwintered colonies on blackberries, and conidia were a source for primary infection during the entire growing season. Secondary spread was through conidia produced in colonies on fruit. L. elatius was observed infrequently producing conidia on fruit during periods of extended high moisture. Histological examination did not reveal penetration of the cuticle of apple fruit for any of the fungi of the apple sooty blotch complex. }, number={1}, journal={PHYTOPATHOLOGY}, author={Johnson, EM and Sutton, TB and Hodges, CS}, year={1997}, month={Jan}, pages={88–95} }

The fungus produces dark, irregular shaped colonies with pycnothyria on the surface of apple fruit. Pycnothyria of P. fructicola were 81-113 ixm in diameter; conidia were borne on an inverted hymenium and were produced in a single locule formed by the separation ofthe dimidiate shield from the surface of the apple. Pycnothyria did not possess a defined ostiole but opened by fissures along the surface of the shield. Paraphyses were not ob? served. P. fructicola produced conidia directly from hyphae immersed within a water agar medium, but no pycnothyria were formed.}, number={1}, journal={MYCOLOGIA}, author={Johnson, EM and Sutton, TB and Hodges, CS}, year={1996}, pages={114–120} }
