|discussion=<p><i>Brachythecium ruderale</i> was known historically from the flora area only from New Mexico, where it was described as B. wootonii, and has more recently been discovered in Arizona, Cochise County, 1950–2130 m (Allen 27950, MO; Goodding 10822, MO). This is the most common species of <i>Brachythecium</i> in Mexico, Central America, and northern South America. The widespread tropical African B. implicatum Hornschuch ex Müller Hal. was considered conspecific with <i>B. ruderale</i> (as B. stereopoma) by W. R. Buck (1993). The typical expression of the species has closely appressed leaves resulting in an almost julaceous appearance. However, sometimes branch leaves are narrow and more loosely arranged. In North America, <i>B. ruderale</i> can be confused with <i>B. acuminatum</i>, which differs in having a shorter acumen, eplicate leaves, and homogeneous cells across the leaf base; with <i>B. laetum</i>, which differs in its more strongly plicate stem leaves, small opaque cells across the leaf base, and rather short distal laminal cells; and with B. oedipodium, which differs in having eplicate leaves and conspicuous, long and broad decurrencies. In <i>B. ruderale</i>, the pellucid or opaque alar regions reach from the margin 33% distance to the costa and extend distally to just below the broadest point of the leaf.</p>
