Species

Cookeina colensoi (Berk.) Seaver (1913).
Basionym Peziza colensoi Berk (1855).
Apothecia cupulate, subsessile to stipitate, 5–19 mm in diameter when dry, receptacle surface smooth; gelatinous layer present in the inner ectal excipulum, 40–50 µm thick, cells of axes somewhat perpendicular to receptacle surface; asci suboperculate, 330–360 × 12.5–13 µm. Ascospores are subfusoid-ellipsoid, smooth-walled, contain two or three oil droplets, and have dimensions of 27–30 × 10.5–12 µm. Known from the South Pacific and South America, and Cameroon. Weinstein and Pfister characterize the distribution as sub-tropical, but more prevalent in the southern hemisphere.

Cookeina speciosa (Fr.) Dennis (1994).
Apothecia funnel-shaped, stipitate, rarely sessile, margin covered with fine, inconspicuous hairs; hairs fasciculate, less than 3 mm long; asci 300–400 × 17–20 µm; ascospores ellipsoid, biguttulate, surface with fine longitudinal ridges, 25–29 × 13–15 µm.
This species has more pronounced variations in color, and is thought to represent a species complex.

Cookeina sulcipes (Berk.) Kuntze (1891).
Basionym Peziza sulcipes Berk. (1842).
Apothecia are goblet- to funnel-shaped, grow solitary to clustered on wood at altitudes less than 700 metres (2,300 ft), and are have dimensions of 2–4 cm (0.8–2 in) in diameter by 3–6 cm (1–2 in) tall. The stipe is slender, 3–4 mm thick, and 1–4 cm (0.4–2 in) long. The hymenium surface is pink to buff in color, while the outer surface is less brightly colored. Ascospores have a cylindrical or ellipsoid shape, containing two large oil drops, covered with fine longitudinal wrinkles, and have dimensions of 25–33 × 14–18 µm. This species is distributed through the lowlands of Central America, Mexico, the Caribbean, South America, Africa, and Asia.

Cookeina tricholoma (Mont.) Kuntze (1891).
Synonyms include Peziza tricholoma Mont., (1834), Pilocratera tricholoma (Mont.) Henn., and Trichoscypha tricholoma (Mont.) Cooke, (1889).
Apothecia are goblet to funnel-shaped with an inrolled margin, 1–2 cm (0.4–0.8 in) in diameter, with slender stipes that are 1–3 cm (0.4–1 in) tall, The apothecia are conspicuously hairy; hairs stiff, bristle-like, fasciculate, and usually 2–3 mm long. Its asci are 280–350 × 13–18 µm. The ascospores pointed-ellipsoid, surface with fine, longitudinal ridges, biguttulate, 25–35 × 11–13.5 µm. The typical habitat is on wood like twigs and rotten tree limbs, at low altitudes (usually below 1000 m), in the tropics. The distribution of this species includes the lowlands of Central America, Mexico, the Caribbean, South America, Africa, Asia, Australia, and the South Pacific.

Cookeina venezuelae (Berk. & Curt in Cooke) Le Gal (1953).
Basionym Peziza venezuela.
Apothecia do not have stipes, are pink to light orange in color, bowl-shaped, smooth, and typically 8–15 mm in diameter × 5–10 mm deep. Ascospores are ellipsoid, pale yellow, contain two large oil drops, have wrinkles and ribs on the surface, and dimensions of 33–36 × 11–13 µm. They grow solitary to clustered on wood, at elevations of 800–1,500 metres (2,600–4,900 ft) in the tropics. The distribution of this less common species is limited to Central America, northern South America, and the Caribbean.

Famous quotes containing the word species:

    If we consider the superiority of the human species, the size of its brain, its powers of thinking, language and organization, we can say this: were there the slightest possibility that another rival or superior species might appear, on earth or elsewhere, man would use every means at his disposal to destroy it.
    Jean Baudrillard (b. 1929)

    Thus all probable reasoning is nothing but a species of sensation. ‘Tis not solely in poetry and music, we must follow our taste and sentiment, but likewise in philosophy, When I am convinc’d of any principle, ‘tis only an idea which strikes more strongly upon me. When I give the preference to one set of arguments above another, I do nothing but decide from my feeling concerning the superiority of their influence.
    David Hume (1711–1776)

    Prohibition will work great injury to the cause of temperance. It is a species of intemperance within itself, for it goes beyond the bounds of reason in that it attempts to control a man’s appetite by legislation, and makes a crime out of things that are not crimes. A Prohibition law strikes a blow at the very principles upon which our government was founded.
    Abraham Lincoln (1809–1865)
