Artomyces pyxidatus

Artomyces pyxidatus, commonly known as the crown-tipped coral fungus, is a species of fungus in the family Auriscalpiaceae. It is notable for its distinctive coral-like appearance and is found in temperate regions of North America and Europe.

Description

Artomyces pyxidatus is characterized by its unique fruiting body, which resembles a coral with multiple branches. The branches are typically white to pale yellow and are crowned with small, crown-like tips. The fungus can grow up to 10 cm tall and 15 cm wide.

Morphology

The fruiting body of Artomyces pyxidatus is composed of numerous slender, upright branches that arise from a common base. The branches are cylindrical and smooth, with a hollow interior. The tips of the branches are often forked and bear a crown-like structure, which is a key identifying feature of this species.

Spore Print

The spore print of Artomyces pyxidatus is white. The spores are elliptical, smooth, and measure approximately 6–8 by 3–4 micrometers.

Habitat and Distribution

Artomyces pyxidatus is saprobic, meaning it feeds on decaying organic matter. It is commonly found growing on decaying hardwood logs and stumps in forests. The fungus prefers moist, shaded environments and is typically observed from late spring to early autumn.

Ecological Role

As a saprobic organism, Artomyces pyxidatus plays a crucial role in the decomposition of wood, contributing to nutrient cycling in forest ecosystems. By breaking down lignin and cellulose, it helps in the recycling of carbon and other essential elements.

Edibility

Artomyces pyxidatus is considered edible, although it is not widely consumed. It is important to properly identify the fungus before consumption, as some coral fungi can be toxic.

Similar Species

Artomyces pyxidatus can be confused with other coral fungi, such as species in the genus Ramaria. However, the crown-like tips of Artomyces pyxidatus are distinctive and help differentiate it from other similar species.
