General Description:

Ostracoderma has cup-shaped fruiting bodies that are usually a little less than one centimeter in diameter. They are pale brown to umber, and are usually semi-translucent. They have ellipsoid hyaline spores between 6 and 8 micrometers in size. Ostracoderma has an apothecial state and a conidial state; its conidial state was previously thought to be another species, Chromelosporium ollare.


Unknown. Widely found in greenhouses located in Europe.


Their most common habitat is greenhouse soil, where they are often able to incubate even after steam-sterilization.


Ostracoderma can be problematic to plant growers because of its mycelium’s imperviousness to water – plants are limited in growth rate by its presence. It has no known uses.
