In addition, P. lilliputana is coprophilic and differs in having a semiglobate to convex pileus that is reddish-brown, and the stipe apex is pulverulent, with sparsely fibrillose veil remnants. In micromorphology, it can be easily distinguished from our species by its rarely forked pleurocystidia and cheilocystidia, and yellowish-red basidiospores, which are sometimes snout-like at the apex or irregular in outline (Örstadius et al. 2015). In the phylogenetic tree, P. qujinguniversitatica is closely related to P. lilliputana and P. mycenoides T. Bau. Their basidiomata are all less than 5.0 mm. However, P. mycenoides differs in having smaller basidia and a dirty white to pinkish pileus (Örstadius et al. 2015; Yan and Bau 2018 a). Based on the above evidence, we identify our collection as P. qujinguniversitatica sp. nov.</p></div>	https://treatment.plazi.org/id/047BB9588EBB535B92628B641C886419	Public Domain	No known copyright restrictions apply.

It is also distinguished by its fibrillose veil, basidioles arranged in a regular pattern, and pale brown to brown basidiospores. Psathyrella piluliformis has a pileus that is brown to reddish brown or honey brown, hygrophanous, with blunt, rounded protrusions in the center, and faint, translucent stripes along the edge (Yan 2018; Kuo 2020). Psathyrella yunnanensis differs from P. carinthiaca in having a lighter-colored pileus, larger pleurocystidia (44.0–62.8 × 9.0–18.0 µm vs. 30–45 × 8.0–13.7 µm), larger cheilocystidia (33.1–46.7 × 10.1–14.8 µm vs. 17–37 × 8–12 µm), and larger basidia (25.2–32.6 × 6.3–8.3 µm vs. 10–18 × 5–7 µm). In contrast, P. carinthiaca is characterized by a reddish-brown to brick-red or brownish (pinkish-) violaceous pileus, blackish violaceous lamellae, and smaller basidiospores (5.0–6.0 × 3.0–3.7 µm vs. 6.4–8.1 × 3.2–4.4 µm) (Voto 2011; Voto et al. 2020). Psathyrella pertinax (Fr.) Örstadius has a pileus color ranging from reddish brown to ochraceous brown to yellow brown, and the pileus often becomes radially rugose, veined, or reticulate (Örstadius 2007). The main identifying feature of P. oboensis Desjardin &amp; B. A. Perry is that the gills are extremely dense, slender, and 1.0– 1.5 mm wide (Desjardin and Perry 2016). Based on the above evidence, we identify our collection as P. yunnanensis sp. nov.</p></div>	https://treatment.plazi.org/id/4546B6B3E3875DF09D3BDA9FC80068A8	Public Domain	No known copyright restrictions apply.
