tus hilo plus-minus protuberanti, plerumque conspicuo, pro ratione lato (cca 4-—7 u,m), in parte superiore cellulae apicalis conidiophori plerumque conspicue dilatata aero- et pleurogena, post disiunctionem vestigia annuliformia singula relinquentia, 20—24 (—28,5) X 13—15 u.m. Typus: No. 8772. Matrix: Fagus silvatica L.: in ligno putrido. In valle Márványkőárok (seu Márvány völgy), pr. pag. Bakonykoppány montium Bakpny, Hungária 29. VII. 1960. leg. S. TÓTH. In herbario Sectionis Botanicae, Museum Historieonaturale Hungaricum, Budapest, Hungária. Mycelium immersed. Stroma none. Setae and hyphopodia absent. Conidiophores macronematous, mononematous, erect, straight or flexuous, brown, unbranched, smooth, solitary or clustered a little, up to 240 [xm long, 6—7 u.m thick, often swollen at the base, sparingly septate, apically with a compact conidiumhead. Conidiogenous cell polyblast'ic, integrated, terminal, sympodial, clavate, with scars corresponding to the hilum of the conidia. Conidia solitary, pale to dark brown, smooth, ovoid, near the apex 1-septate, mostly with a thick, dark band at the septum, 20—24 (—28,5) x 13—15", m. The new species differs from Cordana pauciseptata PREUSS, the type species of the Cordana genus, by the size and of the wide hilum of its conidia, and to some extent, its dissimilar form as well. On the apical cell („conidiogenous cell") of the conidiophore I could not observe any in young state perhaps observable denticula after the abscission of the conidia, but only scars, i.e. ring-like edges, protruding from the surface and agreeing with the hilum of the conidia. This deviation seems me to be reasonable : there is a bigger conidium, a wider hilum, an even shorter or, more correctly (?) missing denticulum on the conidiogenous cell. It is worthwhile remarking that I did not succeed in observing denticula on the conidiogenous cells after the fall of conidia on a material originated from Congo (Africa), and three from Hungary, qualified undoubtedly as Cordana pauciseptata PREUSS. I succeeded in finding the Cordana crassa sp. n. once more : No. 8773. In ligno emortuo. In valle Cuhavölgy pr. pag. Zirc montium Bakony, Hungária 6. XI. 1962. leg. S. TÓTH. Sphaeronaeniella horánszkyi (TÓTH) comb. n. Basionym. : Ceratocijstis horánszkyi TÓTH, Ann. Hist.-nat. Mus. Nat. Hung., 1963, 55: 182—183. The species Ceratocystis horánszkyi described by me in 1963 does not belong to the Ceratocystis genus. It differs from that by its peritheeia which are light coloured, has not more than a cartilaginous substance in its dry state as well, and has an elastically soft substance in its wet state. These features are characteristic, however, for the Sphaeronaemella KARST, genus only, so I had to translocate this species here, from genus Ceratocystis ELL. et HALST. I should like, in addition, to remark that I did not yet succeed in finding this species anew, after its first recovery. Author is indebted to Zs. BÜNKÉ (Botanical Department, Hungarian Natural History Museum, Budapest) for the fine and careful inking of figure contained in this paper. 3 Természettudományi Múzeum Évkönyve 1975.
