Geastrumia polystigmatis

Geastrumia polystigmatis is a species of fungus in the family Geastraceae. It is a rare and unique species, known for its distinctive features and habitat.

Taxonomy

The species was first described scientifically in the year 2000. The genus name Geastrumia is derived from the Greek words ge, meaning earth, and astron, meaning star, referring to the star-like appearance of the fruit bodies when viewed from above. The species epithet polystigmatis refers to the multiple stigmata (openings) in the spore-bearing structures.

Description

The fruit bodies of Geastrumia polystigmatis are spherical to slightly flattened, with a diameter of 1–2 cm. The outer layer (exoperidium) is initially smooth and white, but becomes brown and cracks into polygonal areas as it matures. The inner layer (endoperidium) is smooth and greyish, with multiple small openings (ostioles) through which the spores are released.

The spores of Geastrumia polystigmatis are round, with a diameter of 3.5–4.5 µm. They are brown in color and have a rough surface.

Habitat and distribution

Geastrumia polystigmatis is found in tropical and subtropical regions, where it grows on the ground in deciduous forests and grasslands. It has been reported from various countries in South America, Africa, and Asia.

Conservation status

Due to its rarity and specific habitat requirements, Geastrumia polystigmatis is considered to be at risk of extinction. Conservation efforts are needed to protect its habitat and ensure its survival.
