Lobe, cross section. Beneath the paraplektenchymatic upper cortex follows the layer with the symbiontic cyanobacteria (Nostoc). Under this layer we see a layer of loose ordered mycelium. There is no lower cortex. Microscopy, Stereomicroscope, Microfoto |

Apothecie, cross section. Beneath the brownisch epihymenium we see the hymenium that mainly consists of paraphysies. Between the paraphysies there grow the asci with the eight-celled spores in them. Beneath the hymenium follows the more fluffy subhymenium. Microscopy, Stereomicroscope, Microfoto |
