Note: Echria gigantospora and E. macrotheca are morphologically similar in that both have ascomata covered with long pointed tufts of agglutinated rigid hairs and striated gelatinous sheaths that swell in water and surround their ascospores. They differ in that E. gigantospora has larger (84–126×20–34 μm), fusiform spores with a roughened spore wall (Raja and Shearer 2006), while E. macrotheca (Fig. 3o-q) has smaller (43–54×20–29 μm), ellipsoidal spores (Lundqvist 1972). They also seem to prefer different substrates as E. gigantospora is described from submerged wood, while E. macrotheca is coprophilous.
