Simocybe sumptuosa (P.D. Orton) Singer (illustrated almost life size) Cap 4–25mm across, shallowly convex; tan-brown, usually with an olivaceous tinge; velvety pruinose under a lens. Stem 6–30×1–3mm; light olive-brown. Flesh olive-brown; smell acidic. Gills adnexed; pale tan-buff, often tinged olivaceous. Spores 6.5–10×4–5.5¼, bean-shaped, smooth. Spore print brown. Cheilocystidia and dermatocystidia rather elongated cylindrical-flexuose, often with a swollen apex 6–14¼ wide. Habitat on deciduous stumps or logs; autumn. Occasional. Not edible. Note in my first book this picture was named Naucoria centunculus (Fr.) P.D. Kumm., but Reid (1984) has reassigned the collection to S. sumptuosa.
