STUDIA BOTANIGA HUNGARICA (Antea: Fragmenta Botanica) XX. 1938 p . 95.100 Dematiaceous Hyphomycetes inhabiting forest debris in Hungary III. By Á. RÉV AY (Received November 30, 1987) Abstract: Twenty-three species of lignicolous and other saprophytic Hyphomycetes belonging to 20 genera are reported from Hungary. Some of the recorded 23 species are common, 14 are new to Hungary. Some dematiaceous Hyphomycetes have recently been reported from Hungary (RÉVAY 1985, 1986). The present contribution reports 23 species, 22 of which were not recorded in the previous accounts, together with additional information on one species reported previously. The material of the species listed below was collected by the author and J. GÖNCZÖL. The examined material is deposited in the Mycological Herbarium of the Hungarian Natural History Museum, Budapest (BP). SPECIES ACCOUNT Acrodictys globulosa (Tóth) M.B. Ellis - Mycol. Pap. 103: 34, 1965. (Pl. V, Fig. 2) Conidiophores erect, straight or flexuous, dark brown at the base, paler towards the apex, 40-80 x 5-7/im. Conidia subglobose, pale or medium brown, smooth-walled, with two transverse and several longitudinal and oblique septa, 15-26 x 16-20 jum, basal cell cylindrical, protruding. - Collected on dead twigs of Fagus sylvatica , near Ómassa in the Bükk Mts, 27 March, 1986. Anavirga dendromorpha Descals et Sutton - Trans. Br. mycol. Soc. 67: 269, 1976. (Pl. Ill, Fig. 1) Detached conidia of Anavirga dendromorpha have been well known for some years from submerged leaf samples collected from the Szén-patak stream in the Börzsöny Mts. So far only free conidia were found on submerged leaves but profuse sporulation of the fungus was found on a decorticated twig of Fagus sylvatica in a sample collected in February, 1986. Some colonies of the fungus consisting of dark, dense masses of growing conidia were seen on the natural substrate mixed with sporulating Anguillospora crassa Ingold. Conidiophores erect, brown, 40-50^um long and 6-7jum wide , consisting of 2-3 cells , growing densely in the colony. Conidia reddish or dark-brown, densely septate, highly variably branched, abundantly filled with lipid globules, the longest branch of the conidia commonly exceeds 500jam, cells of 25-30 x 12-14/im. The degree of branching varies from the most simple onesided branch to complex, plural dichotomous forms. The width of conidia is somewhat wider than described by DESCALS and SUTTON (1976) (the conidia 300-400 x 9-10/im in the holotype). This is the first record of the species from Hungary.
