2. Kernia nitida (Sacc.) Nieuwl., Am. Midl. Nat. View in CoL 4: 379 (1916)
( Plate 1 View PLATE 1 , Figs. 5–6)
Ascomata non-ostiolate, gregarious, rarely scattered, superficial, subglobose, ellipsoid, ovoid or polygonal, dark gray to black, 95–290 μm diam. Peridium pseudoparenchymatous, membranaceous, opaque, black, 15–20 μm thick, consisting of several layers of cells, the outermost dark, globose to angulated (textura globulosa -angularis), thick-walled, the innermost brown, clearer, thinner, angular (textura angularis). Terminal hairs simple, thick-walled, septate, smooth, dark brown, 3–6.5 μm thick at the broadest part, 95–600 μm long, arranged in two or three loose tufts of 4–10 hairs, attached at two or three parts of the ascoma, usually inclined upwards to form an angle of approximately 45° in relation to the substrate, with strongly circinate ends, forming hooks in different directions. Lateral hairs hyphoid, simple, thin-walled, 1.5–2 μm thick at the broadest part, usually absent in mature ascomata. Asci 8-spored, globose to ovoid, 6–12.5 μm diam., evanescent. Ascospores 1-celled, ellipsoid, smooth, light brown to ochraceous, copper colored “en masse”, 3.5–6 × 2.5–4.5 μm, guttulate, with one terminal germ pore.
Material examined: — BRAZIL. Pernambuco, Instituto Agronômico de Pernambuco ( IPA), Caruaru , on goat dung, 27 Dec 2011, R. F. R. Melo ( URM86679 View Materials !, 86680!) ; Instituto Agronômico de Pernambuco ( IPA), Serra Talhada , on goat dung, 27 Feb 2012, R. F. R. Melo ( URM86681 View Materials !) .
Habitat: —Soil, plant material and dung of many herbivores.
Distribution: —Worldwide.
Notes:—Ascomata of Kernia nitida were commonly recorded in the studied areas, mainly from goat dung. This species can be distinguished by the peculiar shape of the cleistothecia (subglobose, ellipsoid, ovoid or polygonal) and the long, circinate hairs, originating from two or three opposite points of the ascoma. The material examined from goat dung presented many ascomata covering entire pellets, interspersed with white, cottony tufts forming a hairy surface on the substrate.
