... esculentoides M. Kuo et al.) and M. fluvialis Clowez et al., can also resemble M. dunensis: The first is not or only weakly rufescent with age, contrary to the second, which is strongly rufescent; both species, however, display mostly elongate pilei with partially longitudinally arranged pits and smooth ridges, and have a typically hygrophilic ecology, in riparian forests or poplar plantations (Clowez 2012, Kuo et al. 2012). Microscopically, both M. americana and M. fluvialis appear to have shorter hairs on the stipe [30–70 × (–9) 12–14 (–30) μm and 30–75 × 10–15 μm, respectively, Clowez 2012], whereas M. fluvialis has asci with croziers (Clowez et al. 2014), a feature not seen in any of the M. dunensis collections studied by us (although irregular outgrowths arising from the basal hyphae have been occasionally observed, seeFig. 11e). ...
