|discussion=<p>Although <i>Haplodontium macrocarpum</i> is associated with mineral-rich rock, collections come from a wide variety of rock types. In the southern and central Rocky Mountains, the species is apparently restricted to limestone. Some specimens from the Aleutian Islands have a strongly excurrent costa, and in some respects approach the Asian <i>Mielichhoferia</i> (<i>Haplodontium</i>) himalayana Mitten.</p><!--
