Grovesinia pyramidalis

Grovesinia pyramidalis is a species of fungus in the family Sclerotiniaceae. It is a rare and unique species, known for its distinctive pyramidal shape and its habitat in the soil and on decaying plant material.

Taxonomy

The genus Grovesinia was first described by the British mycologist John Webster in 1955. The species Grovesinia pyramidalis was later added to the genus. The genus name Grovesinia honours the British mycologist John W. Groves, while the species epithet pyramidalis refers to the distinctive pyramidal shape of the fruit bodies.

Description

Grovesinia pyramidalis is characterized by its pyramidal fruit bodies, which are typically 1–2 cm in height and width. The fruit bodies are initially white, but become brown with age. The spores are elliptical and smooth, measuring 5–7 by 3–4 µm.

Habitat and distribution

Grovesinia pyramidalis is a saprobic fungus, meaning it obtains its nutrients from decaying organic matter. It is typically found in soil and on decaying plant material, particularly in forest environments. The species has a wide distribution, having been reported from various locations in Europe, North America, and Asia.

Ecology

As a saprobic fungus, Grovesinia pyramidalis plays an important role in nutrient cycling in forest ecosystems. By decomposing organic matter, it helps to return nutrients to the soil, promoting plant growth.
