Spores: long, lemon-shaped under the microscope, dull brown, warted all over but for the distinct germ-pore; 12-15 × 7-8 µm in size. Marginal cystidia: variable spindle-shaped with flexuous neck and subcapitate apex, about 5-6 µm wide. Facial cystidia: absent. _Habitat_ & _Distribution_: Common amongst short grass on lawns, in pastures, on grass-verges, etc., from May until October. [Illustration: Plate 39. Fleshy fungi: Spores purple-brown and born on gills] _General Information_: _P. foenisecii_ is recognised under the microscope by the ornamented spores; this character was used to separate this fungus in the new genus _Panaeolina_. However, although the spore-print is not exactly black the stature, mottled gills and anatomy conform closely with _Panaeolus sphinctrinus_ (Fries) Quélet and _P. rickenii_ Hora (see p. 210 and below respectively). The same fungus has been placed in _Psilocybe_ (see p. 114), but it has little in common with members of that genus. The word ‘foenisecii’ means hay-harvest, reflecting the habitat of growing in fields. This fungus is variable in colour depending on its state of turgidity; it can be easily confused with other species of _Panaeolus_ when moist and with certain species of _Conocybe_ when dry. _P. rickenii_ is an equally common agaric growing on similar or slightly less base-rich soil-types. It has a distinctly bell-shaped reddish brown cap with a pale incurved margin which in wet weather is, like the entire stem, beaded with droplets of liquid. This gives the fungus a glistening appearance when seen fresh and as it dries these droplets are lost and the cap becomes slightly zoned. The stem is pale reddish-brown with a strong frosted appearance because of the minute hairs which cover it. I have no doubt that the classification of these fungi will be assisted by careful analysis of the shapes of the hairs found in the different species. _Illustrations_: _Panaeolina foenisecii_--LH 145; WD 78⁴. _Panaeolus rickenii_--LH 145.

Cap: at first cylindrical or oval then bell-shaped, fleshy, fragile, white and covered with woolly, whitish, shaggy scales which have brown tips; the centre of the cap is smooth and yellow to ochraceous whilst the margin becomes striate and lilaceous and finally black as the tissue liquefies (autodigests) and the margin rolls up to expose new areas of spore-bearing tissue. Stem: tall, white, smooth and tapered towards the apex, with a white ring which can easily move up and down the stem with handling, and which soon disappears with age. [Illustration: Plate 40.
