Tapesia acuformis

Tapesia acuformis is a species of fungus in the family Helotiaceae. It is a saprophytic fungus, meaning it feeds on dead or decaying organic matter. This species is known for its unique morphology, characterized by its acutely conical shape.

Taxonomy

The species was first described in the scientific literature by the mycologist John S. Karling in 1945. The genus name Tapesia is derived from the Greek word 'tapesios', meaning 'elongated', while the species epithet 'acuformis' is derived from the Latin words 'acu', meaning 'sharp', and 'formis', meaning 'shape'. This refers to the distinctive conical shape of the fungus.

Description

Tapesia acuformis is characterized by its acutely conical shape, which is unique among fungi. The fruiting bodies, or ascocarps, are typically 1–2 mm in diameter and 1–3 mm in height. The outer surface of the ascocarp is covered in a layer of short, stiff hairs, while the inner surface is smooth and shiny. The ascocarps contain numerous asci, each of which contains eight ascospores. The ascospores are hyaline (transparent), and have a unique, elongated shape.

Distribution and habitat

Tapesia acuformis is a cosmopolitan species, meaning it is found worldwide. It is most commonly found in temperate regions, where it grows on a wide variety of substrates, including dead leaves, twigs, and other plant debris. As a saprophytic fungus, it plays an important role in the decomposition of organic matter and the recycling of nutrients in the ecosystem.
