Chaenotheca

Chaenotheca is a genus of lichenized fungi within the family Coniocybaceae.[1] The sexual reproduction structures are a mass of loose ascospores that are enclosed by a cup shaped exciple sitting on top of a tiny stalk, having the appearance of a dressmaker's pin (called a mazaedium), hence the common name pin lichen.[2]: 15  Genus members are also commonly called needle lichens.[3]
