It is characterized by a vividly colored yellow-orange to red-orange pileus, well-developed partial veil persisting as felty patches around the pileus margin, roughly-fibrous to subsquarrose-squamulose stipe with a bulbous base; rather large basidiospores (10–13.6 × 5.4–7.4 μm) with a truncate apex formed by a large germ pore; variable cheilocystidia in shape; and hymeniform pileipellis.</p><p>The specimens collected in China in this study were morphologically similar to the original description of A. eduardii . In the phylogenetic analyses (Fig. 1), the Chinese samples were grouped with the type of A. eduardii monophyletically with high statistical support.</p><p>In the phylogram, A. eduardii was sister to A. dura with high statistical support (Fig. 1). However, morphologically, the former has a vivid orange pileus, margin becoming strongly revolute and lacerate in age, and flask-shaped to subclavate cheilocystidia with a hyaline or straw yellow inclusion in KOH; the latter has a cream-white to pale yellow pileus, short-stipitate vesiculose to broadly ellipsoid or medially constricted elongate-clavate cheilocystidia, and vesiculose to broadly ellipsoid or clavate pleurocystidia with upper-medial constriction (Jin 2012).</p></div>	https://treatment.plazi.org/id/DF23F33D510F5F19BCE16E36B92C760F	Public Domain	No known copyright restrictions apply.

Pholiota caespitosa and Ph. gummosa (Lasch) Singer are also related to Ph. songjiangensis .
