New Zealand: NORTHLAND: Omahuta S.F., on Agathis australis, P. R. Johnston, G. J. Samuels, 14.IV.1982 (PDD 44690). BULLER: Buller Gorge, 11 km S. of Murchison, Fern Flat Rd, on Weinmannia racemosa, P. R. Johnston, G. J. Samuels, 16.IV. 1983 (PDD 43971).

Central America: CUBA: Cuba Fungi No. 712, Wright 1857 (isotype of Stictis foliicola - FH). PANAMA; Prov. Cocle, vic. La Mesa, on unidentified leaf, K. P. Dumont, S. E. & S. M. Carpenter, S. A. Mori, 14.VI.1975 (NY - PA315).

South America: COLOMBIA: Dpto. Cauca, El Tambo, Vereda Guazabarita, on unidentified leaf, K. P. Dumont, J. H. Haines, J. M. Idrobo, L. F. Velasquez, 15.VII.1974 (NY-CO1405). VENEZUELA: boundary Dpto. Federal and Edo. Miranda, La Silla, on Clusia sp., K. P. Dumont, J. H. Haines, B. Manara, 18.VI.1971 (NY-VE106).

Ascocarps forming on upper and lower surfaces of Fallen leaves; not associated with a differentiated lesion. Ascocarps round in outline, 0.3-0.5 mm diam. Ascocarps initially having the appearance of small, raised pustules on host surface. Opening by several, irregular, radiate splits, exposing the white, pruinose hymenium.

Ascocarps subepidermal. In vertical section the marginal tissue comprising a few layers of hyaline, thin walled hyphae, and a poorly developed layer of periphyses. The periphyses becoming intermixed with crystals, which form a broad, wedge-shaped layer near top of margin. Subhymenium rests directly on disintegrating host tissue.

Paraphyses 1-2 µm diam., undifferentiated to slightly and irregularly swollen near the apices, often with short side branches, intermixed with scattered crystals, not extending beyond asci. Asci 72-101 x 6.5-9.5 µm, cylindric, apex broadly rounded to acute, uniformly thin walled, non-amyloid, , 8-spored. Ascospores 53-72 x 1.8-2.5 µm, not tapering, 0-1 septate, gelatinous sheath present.

CHARACTERISTICS IN CULTURE: Ascospores of PDD 43971 and PDD 44691 germinated on agar plates. Colonies on oatmeal agar 2-3 cm after 12 weeks; aerial mycelium white to slightly pink, cottony to felted; agar brownish near centre of colony. Remaining sterile.

Found on fallen leaves of a number of plants, including Agathis australis Salisb., Weinmannia racemosa, and Knightia excelsa. Sherwood (1977) reported this species as common throughout tropical and subtropical America.
