Descriptions
Cephaleuros virescens Kunze 1828 [1827]
Type: Foliicolous algae; Description: Thallus polystromatic, subcuticular or subepidermal, roughly circular with a crenate margin, appearing as a greenish to orange raised spot composed of irregularly branched, prostrate filaments forming a parenchymatous disc; on the upper surfaces of leaves. Erect hairs abundant, penetrating the cuticle, tapering or of uniform thickness, orange, 80–90 μm long. Sporangiophores erect, 2–several cells long, solitary or in tufts of 3–5. Sporangia (1–7) borne slightly obliquely on a short curved stalk which develops from the swollen tip of the sporangiophore, globose to ellipsoidal, 18–27 × 18–22 μm, warty. Zoospores quadriflagellate. Gametangia sessile, obovoid, 17 × 22 μm, produced on subcuticular, prostrate filaments. Leaf spots roughly circular, raised, greenish to orange, appearing hairy because of abundant development of erect hairs, up to 20 mm in diameter.
Distribution: Northland, Auckland, Coromandel, Waikato, Bay of Plenty, Taranaki, Wanganui, Wellington, Gisborne, Nelson, Dunedin.; 1st Record: Chapman et al. (1957).
Significance: This is the alga most commonly found on leaves. In tropical countries it is responsible for the serious ‘red rust’ disease of Thea sinensis (tea) and other plants of economic importance (Sarma 1986) but it causes little damage in New Zealand.; Host(s): Blechnum discolor, Brachyglottis repanda, Coprosma grandifolia, C. robusta, Corokia buddleioides, Dysoxylum spectabile, Hedycarya arborea, Hoheria populnea, Laurus nobilis, Ligustrum japonicum, Litsea calicaris, Macropiper excelsum, Magnolia grandiflora, Melicope ternata, Melicytus macrophyllus, M. ramiflorus, Passiflora edulis, Persea americana, Pseudowintera axillaris, Schefflera digitata.
