 the mammate structure. Germination not observed. x

Hyphae 6-11 pi thick; resting sporangia 24-42 by 42-71 \x, oval or 

 slightly allantoid, i.e., appearing flattened on one side in longitudinal 

 outline, mostly circular in outline in cross sectional view; wall 2-4.2 u. 

 thick, pale yellow under microscope, consisting of an inner, smooth, 

 hyaline layer and an outer layer which is variously sculptured or rarely 

 smooth; wall typically with 3-20 or more circular or oblong thin areas 

 on each side, the circles being thin areas in the wall between thicker 

 ridges or bands, usually with several small, rounded or elongated pits 

 in the thin areas; circles usually 2-6.4 \x wide; wall sometimes with 

 minute rounded or elongated pits, these small pits scattered over the 

 entire surface or sometimes arranged in two bands which border the 

 dehiscence groove, or with thick and thin irregular bands; all resting 

 sporangial types with interconnecting forms; in median cross sectional 

 view wall showing several (usually seven to nine) more or less conspic- 

 uous rounded elevations, between each two of which is a smaller 

 elevation, the larger ones being sections of the bands and the smaller 

 the thin, circular areas between the bands; each resting sporangium 

 with a preformed longitudinal groove located in the middle of the 

 most conspicuous band. 1

Related to Coelomomyces bisymmetricus but with larger resting 

 spores whose walls, though variable in their markings, are characterized 

 by large, thin, circular or oblong areas, bordered by thicker bands.
