Pleospora herbarum (Pers.) Rabenh. 1857

In New Zealand Pleospora herbarum occurs as a saprophyte, as a weak secondary pathogen or in some cases as a primary pathogen. Strains that are primary pathogens are usually host specific. Slade (1963) showed that on lettuce in Auckland, Hawke's Bay, and Manawatu districts, it occurs as a primary pathogen. He also showed that isolates of this fungus from Solanum nigrum infected lettuce. He recommended regular sprays with captan or maneb for its control. A culture from chrysanthemum from Palmerston North was shown to be associated with a ray floret blight. Isolates from Lucerne leaf spot and leaf spot on Gladiolus were also shown to be pathogenic to these two hosts respectively. Brien, Chamberlain, et al. (1959) noted that on onions it occurred as a weak parasite on flower stalks and leaves, usually following downy mildew (Peronospora destructor). On lemons, passionfruit, gorse, carnations, and lupins it is associated with a tip dieback either as a saprophyte or as a weak wound pathogen following damage by insects or weather. It is also recorded as a rot of tomato fruits (Dingley, 1960b) and as a storage rot of apple fruits (Cooper and Padfield, 1965).

Pleospora herbarum (Pers.) Rabenh. 1857

Type: Foliicolous Fungi; Description: Ascomata stromatic, perithecial, scattered, subepidermal, globose to ovoid, black, up to 0.5 mm in diameter, papillate; on leaves and twigs. Asci clavate-cylindrical, 150 × 40 μm. Ascospores muriform, with 7 transverse septa and two (or sometimes one) longitudinal septa in each cell, 24–40 × 11–16 μm, smooth, yellowish brown. Conidiophores often grouped, pale brown to olivaceous brown, up to 80 µm long. Conidia broadly ellipsoidal, muriform with usually 3 transverse and 1–3 longitudinal septa, 25–42 4 25–30 μm, minutely verruculose, brown to olivaceous brown.
Distribution: Auckland, Waikato, Bay of Plenty, Taranaki, Taupo, Wanganui, Wellington, Hawkes Bay, Wairarapa, Nelson, Buller, Westland, Marlborough, Mid Canterbury, South Canterbury, Dunedin, Southland.; 1st Record: Cunningham (1922: as Macrosporium parasiticum).
Significance: A very common saprobe, particularly on herbaceous plants, this fungus also acts as a weak wound pathogen. It has been recorded as a primary pathogen of Lactuca sativa (Slade 1963). Under the microscope, the numerous asci with their distinctive muriform, yellowish brown ascospores present the appearance of a text book illustration of an ascomycete.; Host(s): Acacia melanoxylon, Citrus limon, Lupinus angustifolius, L. arboreus, Malus ×domestica, Passiflora edulis, Ulex europaeus.

taxonomic status
In a strict sense P. herbarum has been placed in synonymy with Stemphyllium vesicarium, but many of the names placed in synonymy with P. herbarum in NZFungi have not been studied in recent years, so keepo the name here in a senso lato concept. [PRJ, May 2019]
