| Capillitium of slender, flexuous brown threads forming a dense network of rather small meshes. |
| Distinguished from Perichna by the terete plasmodiocarp and by the more spinulose capillitium. |
| When mature they dehisce by a small opening, and when broken open will disclose the olive or greenish-yellow capillitium. |
| The capillitium is very even the taeniae closely wound, the elater-ends often furcate. |
| Varies to forms with single peridium and simple physaroid capillitium. |
| This common species is well marked both by its color and by the delicate attachment of the capillitium to the calyculus. |
