描述或重新描述了九种 Nectria。所有子囊孢子都是无色且有条纹的；它们的子囊壳是橙色的，在氢氧化钾中不会变成红色。代表了三组物种。其中一组包括 Nectria grammicospora、N. cf.grammicospora、N. subquaternata 和新种：N. grammicospora。 Grammicosporopsis、N. lucifer 和 N.新禾小孢子菌。第二组包括新物种N。绿胶藻和N.隔膜囊壳。第三组以单一新物种N为代表。泪果属。描述了这些物种的生命周期。 N. 变形体grammicospora、N. grammicosporopsis、N. lucifer 和 N. grammicosporopsis subquaternata 是 Clostachys 的物种。变形者，ofN。 Neogrammicospora 与顶孢菌属或头孢菌属类似，具有单枝分生孢子梗和膜孢子分生孢子，而 N. cf.grammicospora 是顶孢菌状的，具有无小孢子分生孢子。 N 的变形体。绿胶藻和N. Septomyrotheciae 有绿色分生孢子。 N的变形者。绿胶团是Myrothecium sp.；其分生孢子是单细胞的，分生孢子是分生孢子。 N的变形者。 Septomyrotheciae 是Septomyrothecium cf.uniseptatum；其分生孢子是分生孢子，分生孢子是双细胞的。新属和新种 Dacryoma alba 被描述为 N 的无性型。泪果属。所有这些真菌均分布于泛热带或澳大利亚。
Nine species ofNectria are described or redescribed. Ascospores of all are colorless and striates; their perithecia are orange and do not become red in KOH. Three groups of species are represented. One group includesNectria grammicospora, N. cf.grammicospora, N. subquaternata, and the new species:N. grammicosporopsis, N. lucifer, andN. neogrammicospora. A second group includes the new speciesN. chlorogloea andN. septomyrotheciae. The third group is represented by the single new speciesN. dacryocarpa. The life-cycles of these species are described. Anamorphs ofN. grammicospora, N. grammicosporopsis, N. lucifer, andN. subquaternata are species ofClonostachys. The anamorph, ofN. neogrammicospora isAcremonium- orCephalosporiopsis-like in having monophialidic conidiophores and phragmosporous conidia, and that ofN. cf.grammicospora isAcremonium-like with amerosporous conidia. The anamorphs ofN. chlorogloea andN. septomyrotheciae have green conidia. The anamorph ofN. chlorogloea isMyrothecium sp.; its conidia are unicellular and the conidioma is a synemma. The anamorph ofN. septomyrotheciae isSeptomyrothecium cf.uniseptatum; its conidioma is a sporodochium and the conidia are bicellular. The new genus and speciesDacryoma alba are described for the anamorph ofN. dacryocarpa. All of these fungi are pantropical or Australasian in distribution.
