~H. hypothejus~ (Fries) Fries has an olive-brown slimy cap, yellow stem and gills; the stem is slimy and smooth. It is found in pine woods and under pines on heaths. ~H. pustulatus~ (Persoon) Fries has an ash-grey cap brownish towards its centre, viscid white stem with dark grey dots at the apex and white gills. _H. agathosmus_ (Secretan) Fries is similar, but smells strongly of bitter almonds. Both species are found in plantations. Species of the genus _Hygrophorus_ are infrequently encountered in Britain, although twenty species are recorded for the British Isles. They are ecologically distinct from members of the genus _Hygrocybe_ in preferring woodland communities to grassland areas; they are probably mycorrhizal. The anatomy of the fruit-body is also rather different to that found in _Hygrocybe_; the gill-trama is bilateral as in _Leccinum_ (p. 27), _Suillus_ (p. 28), _Boletus_ (p. 31), _Chroogomphus_ (p. 36), _Paxillus_ (p. 38) and _Amanita_ (p. 54). Members of the genus _Hygrocybe_ have regular to irregular gill-tramas. In fact, although both genera are united into a single family, the Hygrophoraceae is based on one character common to both, i.e. the long basidium; there is every indication that the genus _Hygrocybe_ has greater affinity to _Omphalina_ in the Tricholomataceae (p. 232). Surprisingly enough in North America many of our familiar grassland species including _H. pratensis_ are to be found in deep shaded woodland! Angular, pink-spored agarics--Rhodophyllaceae The name of the family refers to the pink gills and it unites all those fungi with a salmon-pinkish buff spore-print and whose spores are angular in all optical sections. There are a few agarics, e.g. _Clitopilus prunulus_ (Fries) Kummer with ridged spores which appear angular in end-on view, but which are ellipsoid in both side and face views and so are considered less related. The family _Rhodophyllaceae_ by some authorities contains one genus _Rhodophyllus_, more correctly called _Entoloma_; in the British Isles five constituent genera are recognised, but they will have to be more critically defined to make a more meaningful classification. At the moment, many of the species are poorly documented and it would appear that anatomical studies will assist in the future in the recognition of species-groups. If one selects the eight most distinctive shaped spore-types exhibited in members of this family, then when their spores are examined side-on a feature is available for correlation with the traditional field characters, such as cap scaliness and gill-attachment. The most distinctive spore-shape is Type G, found in _Nolanea staurospora_ Bresadola, which is probably the most common and widespread species of the family. It grows in woodlands, grassland and on lawns and will be dealt with later (p. 122). The other spore types are illustrated and range from irregularly rhomboid to elongate angular.
