The holotypes or type material of 17 species and one form described as Clitocybe (Fr.) Staude and one species described as Omphalina Que'!. have been scrutinized. All but one of the taxon names treated in the study turned out to be synonyms and represent earlier described species of Clitocybe . One species proved to be a va'lid one, but belongs to Lepista (Fr.) W. G. Smith, so that the new combination Lepista s)<bconnexa (Murr.) Harmaja is made. The present study is a part of the results of the examination of a great number of types or type materials from various parts of the world. The work had to be carried out prior to the publication of my study on the genus Clitocybe in Fennoscandia. Various synonyms (and names suspected to be such have been incorporated in handbooks and been widely used in local floras and even monographs. This could have been avoided by studying the types of these often fairly recently described species, and comparing them with sufficiently extensive material of other, older species, in order to find out whether they possibly fall within the normal amplitude of variation of the latter. However, revision of this type is sometimes difficult since instead of the existing type specimen one may be sent other material, or a small fragment of fruit body of the type specimen. For this reason uncertainties still remain regarding the rather frequently used name C. tenuissima Rom. In addition, I could only obtain very small fragments of C. costata Kuhn. & Rom. and C. subsericella Rom. ( sericella), and was unable to come to any decision in respect of these names (their spores were -+identical with those of C. squamulosa and their pileus gave a chestnut brown KOH reaction, so they may both be very nearly related to C. squamulosa, if not identical with this species). In my treatment of the Fennoscandian Clitocybes (HARMAJA 1969; see p . 114 ) I perhaps did not make it sufficiently clear that, at present, owing to the lack of good protologue and type material, all the species of FRIES which he described on the basis of Fennoscandian (i.e., Swedish ) material have to be considered nomina dubia (apart from · those few, -+clearly distinguished and/or common species which were considered valid in my study, i.e., very likely to be what FRIES meant with them) . The true number of species of Clitocybe in southern and central Sweden is much smaller than that reported by FRIES, even if the different delimitation of the genus is taken into consideration. It is to be hoped that an end may be put to the somewhat nonchalant use in local floras etc. of such names as C. brumalis, C. cacabus, C. mortuosa, C. olorina, C. orbiformis, C. paropsis, C. pausiaca, C. tornata, C. tuba, C. vermicularis and others. If these species cannot be traced and cleared up by studying the Swedish Clitocybe material both in the field
