STUDIA BOTANICA HUNGARICA (An tea: Fragmenta Botanica) XVIII. 1985 p. 73-76 Forest litter Hyphomycetes from Hungary By J. GÖNCZÖL (Received November 30, 1984.) Abstract: Further observations on forest litter Hyphomycetes of Hungary and some rare or interesting species of this group found recently are reported and discussed. Regular observations have been made in recent years on the Hyphomycetes inhabiting forest litters in Hungary. The purpose of these observations .was on the one hand to obtain data about terrestrial Hyphomycetes living on litter leaves, on the other hand to look for aquatic Hyphomycetes living on terrestrial forest litter. Since in a previous paper (GÖNCZÖL & RÉVAY 1983) the rare appearance of aquatic (Ingoldian) Hyphomycetes on terrestrial forest litter has been pointed out, the main attention was turned to the terrestrial litter-leaf Hyphomycetes. The present observations again confirmed that, however, the presence of aquatic Hyphomycetes in terrestrial litter can be demonstrated but their activity and proportion to terrestrial Hyphomycetes is definitely insignificant. Therefore the present paper only deals with the terrestrial species and contains further data and observations to the knowledge of forest litter Hyphomycetes of Hungary. MATERIAL AND METHOD Forest litter samples were collected from the Börzsöny Mts and the Bükk National Park. Samples were usually taken from the lower layer of the litter deposited on the soil where decaying leaves were almost always wet. Decaying leaves were stored in a refrigirator and incubated in petri dishes in moist condition. Leaves decayed and skeletonized to a great extent were kept and incubated in glass-boxes specially made for microscopic observations. This method has been detailed in a previous paper (GÖNCZÖL & RÉVAY 1983). In addition to the leaf material, smaller quantities of other litter debris were collected and observed. Slide preparations of the examined material are deposited in the slide collection of the Mycological Herbarium of the Hungarian Natural History Museum, Budapest. RESULTS AND DISCUSSION During a further one-year period of study of forest litter Hyphomycetes, again a very scanty growing of Ingoldian Hyphomycetes was observed on terrestrial litter leaves. Altogether only Ala- tospora acuminata Ingold and Dactylella submersa (Ingold) Nilsson have on some occasions been observed sporulating on decaying incubated leaves. The previous paper dealing with aquatic and terrestrial species of forest litter Hyphomycetes presented some species to which additional comments may here be of interest. Correspondingly with
