Spores: long, slightly almond-shaped, pale brown under the microscope, distinctly warted and about 11 × 6 µm in size (10-12 × 6-7 µm). Marginal cystidia: cylindrical to skittle-shaped with slightly to distinctly swollen apex. Facial cystidia: absent. _Habitat_ & _Distribution_: Common in autumn on the ground by pathsides and in woodland clearings. _General Information_: Recognisable by the uniform cinnamon or pinkish buff cap, white woolly scales on the stem and distinctive, strong smell of radish. There is some evidence that this species may on occasions be mycorrhizal; further field studies are required. There are several closely related fungi which are difficult for the amateur to differentiate from _H. crustuliniforme_; there is no doubt that there are several species present in the British Isles which do not appear in the Check List of British Agarics & Boleti; in fact, it would appear that there are several yet to be described as new to science. Although individual species are fairly difficult to delimit, the genus _Hebeloma_ itself is easily recognised, most members being medium sized with brown sinuate gills, whitish, yellowish, or pinkish, i.e. pale, caps and white-powdered stems. The word ‘crustulin’ which appears in the Latin name of _H. crustuliniforme_ is itself from the Latin and means small cake, referring to the cap-shape, which remains fairly constant throughout the fungus’ growth. The common name is derived from this also. [Illustration: Plate 20. Fleshy fungi: Spores dull brown and borne on gills] ~Inocybe geophylla~ (Fries) Kummer Common white inocybe _Cap_: width 10-25 mm. _Stem_: width 3-6 mm; length 30-50 mm. _Description_: Cap: conical with incurved margin then bell-shaped and retaining a distinct umbo even when mature, silvery white then ivory and finally pale tan particularly centrally and silky fibrillose throughout. Stem: slender, cylindrical but for a small swelling at the base, silky and shining with a few fibrils from a former cortina which may be brownish due to spores adhering to it at maturity. Gills: adnexed to free, crowded, pale ochraceous becoming clay-coloured. Flesh: white with smell of newly dug potatoes, strong when fresh. Spore-print: clay-colour. Spores: medium sized, ellipsoid or slightly French-bean-shaped, smooth, yellow-brown under the microscope and 9-11 × 4-5 µm in size. Marginal and facial cystidia: flask- to spindle-shaped with distinctly thickened walls and frequently ornamented with crystals apically. _Habitat_ & _Distribution_: Common in troops in woodland clearings, by pathsides or on the edges of ditches bordering woods.
