ABSTRACT Sooty blotch disease of apples (Malus x domestica), previously attributed to the fungus Gloeodes pomigena, was shown to be a disease complex caused by fungi previously considered mycelial types of G. pomigena. 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.
摘要 苹果煤污病（Malus x domestica），以前归因于真菌 Gloeodes pomigena，现已被证实为一种由真菌引起的疾病，这些真菌以前被认为是 G. pomigena 的菌丝体类型。Peltaster fructicola 和 Geastrumia polystigmatis 与枝状菌丝体类型有关。一种与 P. fructicola 相似但具有较小的分生孢子器和分生孢子的真菌与点状菌丝体类型有关。弥漫性煤污状菌丝体是由 Leptodontium elatius 引起的。未观察到符合 G. pomigena 经典形态描述的真菌。P. fructicola 的分生孢子器在黑莓上的越冬菌落上发育，分生孢子是整个生长季节初次感染的来源。二次传播是通过在果实上的菌落产生的分生孢子。在长时间高湿度期间，L. elatius 偶尔会在果实上产生分生孢子。组织学检查未发现苹果煤污病复合体的任何真菌穿透苹果果实的表皮。
