Pholiota veris

[ Basidiomycetes > Agaricales > Strophariaceae > Pholiota . . . ]

by Michael Kuo

Also known as Kuehneromyces rostratus, Pholiota veris is an eastern, hardwood-rotting pholiota that appears in late spring, just after morel season. It features a smooth, buffy-brown cap, gills that are attached to the stem, a fairly smooth stem surface, and a distinctive thin ring that initially flares upward, then collapses and develops a tawny brown edge. The spore print is brown. Under the microscope Pholiota veris features funky, long-necked cystidia.

Pholiota mutabilis is somewhat similar, but it appears in summer and fall, and features a scaly stem. Pholiota vernalis is very similar and does appear in spring (as well as summer and fall), but is usually found on conifer wood; it has a skinnier stem and shorter, fatter cystidia that sometimes develop apical projections.

Description:

Ecology: Saprobic; growing alone, scattered, or in clusters on the well decayed wood of hardwoods (especially oaks and beech); late spring; widely distributed east of the Great Plains.

Cap: 2-6 cm; convex, becoming broadly convex, broadly bell-shaped, or nearly flat; moist at first; tan when young and fresh, fading markedly as it dries out and eventually becoming buff colored; smooth overall but often with tiny fibrils near the margin when young; the margin sometimes finely lined.

Gills: Attached to the stem; close or crowded; whitish to pale tan when young, becoming cinnamon brown; at first covered by a partial veil.

Stem: 4-9 cm long; up to 12 mm thick; dry; with an upward-flaring, whitish to pale tan ring that soon begins to collapse and develop a tawny brown edge; pale tan; smooth or with inconspicuous fibrils just below the ring.

Flesh: Pale brownish.

Odor and Taste: Not distinctive.

Chemical Reactions: KOH negative on cap surface.

Spore Print: Cinnamon brown.

Microscopic Features: Spores 5.5-7.5 x 4-5 µ; smooth; more or less elliptical. Pleurocystidia fusoid-ventricose with a long neck; scattered to absent; to 66 µ long. Cheilocystidia fusoid-ventricose with a long neck; to 62 x 10 µ, with the neck 2-3.5 µ wide. Pileipellis a partially gelatinized interwoven layer of cylindric hyphae.
