Mycelium inconspicuous and saprophytic, or parasitic on algae, forming a powdery, 

 crustose, foliose or fruticose thallus ; apothecia sessile or stalked, cup- to top-shaped, 

 opening more or less completely, asci disappearing very early and the disk then 

 covered with a persistent mass of spores and paraphyses, i. e., mazaedium; exciple
