The Inocybe Species of Hungary By L. Szemere, Somogyfajsz Author presents descriptions and concomitantly critical remarks of the 69 European Inocybe species. 42 species had been found in Hungary, and the occurrence of 27 further species seems probable. The well-known species godeyi Gill. (= 7), bresadolae Masee (=7.) bucknalli Massee (= 45.), viscidula Heim (= 52.), friesii Heim (= 53), striata Bres. (= 53.), and langei Heim (= 63.) do not appear in the list, as author synonymized them with the species Patouillardi Bres (7), flocculosa Berk, et Br. (45), trechispora Bk. (52.), umbrina Bres. (53.), and decipiens Bres. (63.). Author, notably, cannot regard the smoothness or angularity of the spore as a differentiating specific character ; nor the spore or absence of an actual cystid of the fungus in question. (7.). The dimorphism of the spore is presumed in In. petiginosa Fr. sensu Gill, et sensu Bres. (57.) ; and also in In. hystrix Fr (4L). Not alone the congruency of the conspicuous macro-characters are striking in the cases of the fungi compared, but also the similar hues of coloration of their spores, and also the fact that the sizes of both the spores and the cystids fall between the measurement-limitation brackets. The smooth-spored In. hystrix Fr. (41.) agrees with the non smooth-spored In. asinina Kalchbr. Kalchbrenner remarks that his fungus strikingly resembles In. hystrix save that its spore is not smooth. Therefore, because of the differences of the spores, he did not identify the two fungi ; just as Boudier did not draw his smoothspored In. ionipes to In. floculosa (45.), as this latter is not smooth-spored. Even so, he only refers to the similarity. The congruence of the macro-characters occurs in the cases of so many smooth-spored and not smooth-spored double-species that the form of the spore (in the cases enumerated above) being a state only is a much greater probability than that we have to do with as many convergences regarding the macro-characters. With reference to the contention that the presence or absence of actual cystids cannot be regarded as a specific differentiating character, author submits the following consideration : the genus Gloeopeniophora, segregated from the Peniophora, could not be maintained by the demonstration of the fact that the identical species at one time has, and at another time does not have, a gloeocystid. In. lanuginosa Fr. ex Bull, has a real cystid, whilst In. casimiri Vel., considered as its variation, has no real cystid. In. goodeyi and In. patouillardi grow, according to Smotlacha, in similar localities, and often simultaneously. Since only one of the names of the species, drawn together because of the sporal dimorphism, can be sustained (as the other name will shrink into synonimy on the fact that the sporal dimorphism is but a state and not a variety), these species cannot conform with the present considerations; so author designates them as In. trechispora Bk. sensu Szem., etc. The fungus In. petiginosa Fr., makes a notable exception because, on the ground of its double interpretation, it does not have two names.This species has to retain its name as In.petiginosa Fr. sensu Gill, et sensu Bres.
