Context less than 0.8 mm thick. Lamellae 0.5–1.0 mm broad, free to short adnexed, distant, white, becoming brownish orange to light brown (7 C 4–7 D 4) as mature, edge white, smooth to serrate, with two series of lamellulae.

D. Ivanova &amp; O. V. Morozova, with both species having very small basidiomata and well-developed scales or fibrils at an early age. However, the latter has spores that are shorter than 7.5 μm and a white center on the pileus (Crous et al. 2021).  Micropsalliota longicystis T. Gao &amp; Z. W. Ge and  M. pseudoarginea Heinem. are also similar to  M. bispora macroscopically, but  M. longicystis has pleurocystidia and its spores shorter than 6.0 μm (Gao et al. 2024), and  M. pseudoarginea has broadly clavate or ventricose-clavate cheilocystidia and its spores shorter than 5.0 μm (Zhao et al. 2010). Among the known species of  Micropsalliota with a pileus generally less than 10 mm, there are no species like  M. bispora with spores longer than 8.0 μm. Based solely on this characteristic,  M. bispora can be distinctly differentiated from known species of  Micropsalliota .</p><p>M. geesterani (Bas &amp; Heinem.) R. L. Zhao &amp; L. A. Parra,  M. gigaspora T. Gao &amp; Z. W. Ge, and  M. ventricocystidiata Al-Sadi &amp; S. Hussain are similar to  M. bispora, with spores up to 9.0 μm, but their pilei are larger than 20 mm. Additionally,  M. geesterani has a purple pileus, and fusiform, cylindrical, or narrowly clavate cheilocystidia (Parra et al. 2016),  M. gigaspora has clavate cheilocystidia (Gao et al. 2024), and  M. ventricocystidiata has ventricose cheilocystidia (Al-Kharousi et al. 2022).</p></div>	https://treatment.plazi.org/id/87367F777D61510A859FDB08B559AC4D	Public Domain	No known copyright restrictions apply.
