Beschreibung:

Coral Spot Fungus (Nectria cinnabarina). This is a common species, found on dead wood (especially of broad-leaved trees), all year round.

The irregular dark red shapes can be seen to be clusters of smaller structures, which are called perithecia. These are hollow, with a tiny opening (ostiole) at the top; under higher magnification, these openings can be seen as tiny dark dots.

[Another stage of this fungus is sometimes encountered: the conidial stage, which consists of rounded coral-pink pustules from 1 to 4 millimetres across; that stage is shown here: 1091903; it produces asexual spores called "conidia". In contrast, the perithecial stage (the one shown in this photo) produces sexual spores called "ascospores".]
