Sori in ovaries, about 3-4 mm. in diameter, at first hidden by the perigynium, then 

 exposed as subspherical (very rarely more elongate) bodies protected by a false white mem- 

 brane which soon wears away disclosing a black firmly agglutinated mass of spores, with 

 distinct columella ; sterile cells of membrane usually not very distinct because semigela- 

 tinized; spores subopaque, chiefly irregularly polyhedral, occasionally subspherical, or more 

 elongate in lateral view, granular to papillate or sometimes indistinctly pitted, often with 

 signs of hyaline envelope, 16-27 /i, chiefly 18-22 /i, in length.
