Dacrymyces

Dacrymyces is a genus of fungi in the family Dacrymycetaceae. These fungi are characterized by their gelatinous fruiting bodies, often appearing as small, brightly colored, and irregular masses. The name Dacrymyces comes from the Greek words "dakry" meaning tear and "mykes" meaning fungus, referring to the often jelly-like or tear-like appearance of their basidiocarps.

Species within this genus are typically saprobic, meaning they obtain nutrients by decomposing dead organic matter, primarily wood. They are commonly found on decaying coniferous wood, but some species can also colonize hardwoods. The fruiting bodies are often ephemeral and can dry out and rehydrate, a characteristic of many jelly fungi.

The microscopic features of Dacrymyces are also distinctive. They produce basidiospores that are typically elongated and often have internal septations. The basidia themselves are usually forked or Y-shaped, a key diagnostic feature for the genus.

While generally not considered edible or medically significant, Dacrymyces play a role in the decomposition of wood in forest ecosystems. Their distinctive appearance and gelatinous texture make them noticeable, though often overlooked, components of fungal diversity. Common species can include Dacrymyces palmatus, known for its orange, cushion-like fruiting bodies. Identification often requires microscopic examination to distinguish between closely related species.
