|discussion=<p><i>Thelia asprella</i> is a fairly small species that usually grows in large, dense mats at the base of trees. <i>Thelia asprella</i> and <i>T. hirtella</i> are nearly identical in aspect; both species have terete-foliate, regularly branched, densely radiculose stems, and piliferous leaves. <i>Thelia hirtella</i> differs from <i>T. asprella</i> most clearly in having unbranched laminal cell papillae; in addition, the leaves in <i>T. hirtella</i> are dimorphic with stem leaves much larger and more densely ciliate than the branch leaves. <i>Thelia lescurii</i> is a larger plant than <i>T. asprella</i> that nearly always grows on soil or over rocks. In the field, <i>T. lescurii</i> can often be distinguished from <i>T. asprella</i> because its short-apiculate leaves give the plants a smoothly imbricate appearance. In <i>T. asprella</i>, the piliferous apices are often spreading, giving the plants a ragged appearance.</p>
