ANNALES HISTORICO-NATURALES MUSEI NATIONALIS HUNGARICI Tomus 56. PARS BOTANICA 1964. Ustilago fussii Messl By K. VÁNKY, Odorhei (Roumania), S. TÓTH. Budapest G. NIESSL described Ustilago fussii in 1872 (Verhandl. d. Naturforschenden Vereines in Brünn, 10, 1871 [1872] p. 156—157). The text of the original description is as follows : „ Ustilago fussii n. sp. Foliicola ; soris crassis amplisque, sub epidermidc turgida albescente fragili nidulantibus ; sporidiis subglobosis nigris, episporio verruculoso. In acubus vivis Juniperi nanae alpibus Transylvaniae (Fuss). Sori 3—6 mm long, et lat.; Sporidia 10 — 12, plerumque 11 mik diam." To the above diagnosis NIESSL yet made some remarks in German. However, they do not add anything relevant to the Latin text of the description. FISCHER DE WALDHEIM, referring in 1876 to NIESSL'S above description and ils repetition in the 1873 volume of Hedwigia (p. 116), expounds on the data of the description concerning the spores: ,, Mycélium noir. Spores arrondies, de 10—12 micr., noirâtres (NIESSL). Juniperus communis L. — nana WILLD. Dans les feuilles." Though FISCHER DE WALDHEIM emphasized, in the introduction to his paper, that he had examined all available Ustilaginales, he did not expressly state so concerning Ustilago fussii. The few words of description would rather imply that he had not examined the type of Ustilago fussii NIESSL. AS hosts, he mentions both Juniperus communis L., and Juniperus nana WILLD. The listing as host of Juniperus communis L. must be regarded as a mistake, to be explained by the fact that several authors regarded Juniperus nana WILLD. as a simple synonym of Juniperus communis L., while others considered it as only its subspecies or variety. Fuss, to whom NIESSL referred in his original description as the collector or at least dispatcher of the material, mentioned the fungus in 1877 as follows: „323. U. Fussii Nissl(NissL Beitr. p. 6)an den lebenden Nadeln von Juniperus intermedia; Csiker Alpe Hargitta Fronius". Fuss therefore named, as the collector of the material, Fr. FR. FRONIUS, Evangelican pastor in Szentágota (1829—1886; the zealous explorer and collector of the Transvlvanian flora); accurately designated the locality, and mentioned the host under the name of a probable synonym of Juniperus nana WILLD. HAZSLINSZKY, in his paper published in 1877, listed the fungus after the description made by NIESSL. DE TONI, in volume VII of Sylloge fungorum, gives the diagnosis of Ustilago fussii (p. 468) also after NIESSL'S description. And OUDEMAKS, by referring to NIESSL, FISCHER DE WALDHEIM, and volume VII of the Sylloge Fungorum, lists the fungus among those to be found on the leaves of Juniperus communis L., and Juniperus nana WILLD. (Enum. Syst. Fung., I, p. 634, 645). G. MOESZ, in his posthumous work published in 1950, discusses also Ustilago fussii as one of the smuts known from Hungary. Due to NIESSL'S authority, he does not regard the species as doubtful. According to him, the fungus cannot be identified with any of the known fungi on Juniperus, and the failure to find it again subsequently to the description of the type material is no cause yet to consider the fungus as nonexistent, since it must surely grow in hardly accessible localities, and it had happened frequently that fungi not recovered for some decades were later still found, again Therefore MOESZ did not see the fungus, and reported it after NIESSL'S diagnosis.
