The filmy reticulate mycelium at length disappears, and the peridia 

 are scattered, looking at first sight, from their white stems, like 

 Diachma. The species is altogether distinct from Trichia lateritia 

 Lev. The dust of the peridia consists of irregular fragments of a 

 bright orange-red.

 (1768). Sporangia elongated, branching and interwoven, com- 

 bined into a pulvinate or effused sethalium ; the outer layei 

 forming a cortex charged with deposits of lime-granules, without 

 spores ; the inner stratum containing the spores and a well- 

 developed capillitium, with few or many lime-knots ; the lowei 

 layer forming a skin-like hypothaUus.
