The sporangia constituting the aethalium are intricately coiled and anastomosing, but often more or less separated in the mass, with spaces in between; cortex thick or thin, a dense crust of lime or undeveloped Plasmodium, loose or firm, or absent entirely; sporangial walls within the aethalium membranous, fragile, colourless, with scattered deposits of lime-granules.

CAPILLITIUM: scanty or abundant, consisting of a loose network of slender hyaline threads, more or less expanded at the axils, with fusiform or branching lime-knots, usually white but often yellow, or occasionally reddish or brownish.
