DESCRIPTION
PILEUS
- Cap 1-3 (4) cm wide
- hemispherical to convex shape, rarely nearly flat
- sometimes with rounded hump
- mostly bare and smooth, but also wrinkled slightly
- not greasy, margin lined when wet, translucent
- hygrophanous
- Color meat brown, gray, brown, dark brown
- Sometimes concentrically streaked, beige almost white to pale at end, in transition with darker, trolled by marginal zone (similar to Panaeolus cinctulus or P. fimicola).
LAMELLAE
- Gills attached
- ascending, moderately crowded
- Only beige brown, almost black, then brown, spotted, with lighter/sterile edge.
STIPE
- Stipe 30-80 × 1.5-3 mm, cylindrical
- narrow, hollow, frail, bent straight up
- completely frosted upward, fine flaky
- slightly lighter colored than the cap
- In the upper part sometimes almost hyaline, brownish below, drying almost whitish
MICROSCOPIC FEATURES
BASIDIA
- Basidia (1 -) 2 – to 4-spored
- About 25-30 × 10-12 microns.
PILEIPELLIS
- Epicutis cellular
- cells approximately 15-25 microns wide
SPORES
- Spores (11.5) 14-17 (22) x (7.5) 8.5-11 microns, lemon-shaped
- distinctly rough, yellow-brown, transparent
- often flattened in the microscope with large oil drops
- Germ pores often brought forward significantly, especially in 2-spored forms
SULPHIDIA
- Absent
CHEILOCYSTIDIA
- Cheilocystidia hyaline, pot-shaped bottle
- tip occasionally sold capitate,
- About 25-50 microns long.

ITS sequences reveal that Panaeolina is really close to Panaeolus, and should not be its own genus. Morphological features such as the roughened spores are shared with other Panaeolus species.

This is really just a Panaeolus due to habit, habitat, taste and DNA sequences. It was split off from Panaeolus because the spores aren’t completely black and are ornamented – however that split didn’t withstand the test of time, and some Panaeolus have ornamented spores. Phylogenetically this is about 20 bases in the ITS gene from other species of Panaeolus, which isn’t much – many Panaeolus species differ by much more than that.
