Herzogiella striatella
Herzogiella striatella is recognized by its close, squarrose to squarrose-recurved leaves with 2–4 rows of abruptly inflated, hyaline or orange to red, decurrent cells extending 4–6 cells down the stem. This species has a disjunct distribution in North America, occurring commonly in the eastern third of the continent and more rarely in the western part in British Columbia, Alaska, and Washington. Herzogiella striatella may have a closer relationship to H. cylindricarpa (Cardot) Z. Iwatsuki of Mexico, Central America, South America, and Africa than to other North American species, as revealed by a study of spore ornamentation (R. R. Ireland 1990). The report for Alabama by Ireland (1991b) is an error.
