Geastrum subiculosum

Ciri dan struktur

Plants seated upon a mycelial subiculum, small, obovate, umbonate, superficial, attached by a central basal rhizomorph, becoming tardily expanded when to 3 cm. across. Exoperidium saccate, split to about the middle into 6-7 bluntly pointed expanded rays; fleshy layer bay brown, continuous, adnate; exterior free from debris, bay brown, glabrous; base convex, with an umbilical scar. Endoperidium 7-10 mm. diameter, sessile, subglobose, umber brown, glabrous, lower half enclosed by the saccate base of the exoperidium; peristome flattened, obscurely fibrillose, concolorous, seated on a depressed zone. Gleba umber; pseudo-columella inevident. Spores globose, 3.5-4.5um diameter, epispore chestnut brown, 0.75um thick, delicately verruculose. Fructifications grow crowded upon a white subiculum covering the surface of decaying vegetable debris on the forest floor. The species may be identified by the small almost smooth spores. The collection from New South Wales is referred to G.subiculosum partly because of these features, partly as it agrees with the description drawn by Coker & Couch (1928, p. 119) from the type at Kew. They referred here a Jamaican collection which differed in that the spores were smooth and 2-3um diameter.

Habitat dan peran ekologis

Geastrum subiculosum is an inedible species of fungus belonging to the genus Geastrum, or earthstar fungi. The fungus was first described scientifically by Cooke and Massee in 1887 (as Geaster subiculosus; Geaster is an older name for the genus Geastrum), based on material found near Trinity Bay, Australia. The fungus grows on decaying wood, and the fruit bodies are characterized by an extensive velvet-like subiculum (a crust-like growth of mycelium). The spores are roughly spherical and measure 3.6–4.2 μm. The species is found in Australia, Africa (South Africa and the Congo), North America, and South America.
