Plate 122 



This interesting little plant, remarkable for its minute size, is known only from the 

 original locality. Careful search would probably discover it in other parts of the 

 Atlantic seaboard. The types at New York have been studied and agree well with 

 Miss White's description. The peridioles as we find them, are dark reddish brown, not 

 "yellowish brown," and the spores are 4.5-7 x 6-9/x. 



We take the following from Miss White (1. c, p. 276) : 



"Peridia small, elongate-globose, or subspherical, sessile, sometimes confluent, 

 0.5-2 mm. long, 0.5-1 mm. high; peridial walls very thin, and brittle at first, pale 

 yellowish fawn-colored, gradually as the plant matures becoming grayish, and some- 

 what tuberculose from the inner pressure of the sporangioles, dehiscing irregularly, 

 the outer covering often breaking away completely, leaving the sporangioles seated 

 alone on the wood, barely visible without magnification; sporangioles yellowish brown, 

 very numerous, crowded, circular, flattened above and below, barely 0.25 mm. in di- 

 ameter, even or slightly creased under high magnification; spores subglobose, hyaline, 

 thick-walled, 4-7yu long, 3-6/i wide. 



"Gregarious on wood."
