|discussion=<p>A collection from California (Pasadena, “g. 9”, US) has three variants, including <i></i>var.<i> starckeanum</i>, <i></i>var.<i> fosbergii</i>, and what is probably best called <i></i>var.<i> starckeanum</i> but which has an indehiscent operculum, even upon heating in KOH and Pohlstoffe. Another, from Arizona (Pima County, E. B. Bartram 990, Musci Acroc. Bor.-Amer. 572, US) includes <i></i>var.<i> starckeanum</i>, <i></i>var.<i> brachyodus</i>, and the indehiscent variant of <i></i>var.<i> starckeanum</i>. Collections with capsules toward the large end of the size scale, previously called Pottia arizonica, often have entirely smooth spores; commonly, however, some tuberculate and characteristic of <i>M. starckeanum</i> can be identified in at least some capsules. Also, D. F. Chamberlain (1978) described <i>M. starckeanum</i> (as Pottia starckeana) as having smooth or tuberculate spores in his treatment for the British Isles. Capsule contents not differentiating into spores is not uncommon in variants of <i>M. starckeanum</i>, indicating the possibility of occasional hybridization.</p>
