Révay, Ágnes: Dematiaceous Hyphomycetes inhabiting forest debris in Hungary I

STUDIA BOTANICA HUNGARICA (Antea: Fragmenta Botanica) XVIII. 1985 p. 65-71 Dematiaceous Hyphomycetes inhabiting forest debris in Hungary I. By Á. RÉVAY (Received November 30, 1984) Abstract: Lignicolous and some other Dematiaceous Hyphomycetes have been studied using the methods of direct examination and damp-chamber incubation. A list of 47 species, some of which are common, belonging to 38 genera is given. Some of the rare lignicolous Hyphomycetes are also recorded, 10 of them being new to Hungary. Dematiaceous Hyphomycetes occuring on various organic debris such as rotting wood, fallen leaves, herbaceous plants have been examined by numerous mycologists for many years; i.e. ELLIS (1971, 1976), MATSUSHIMA (1971, 1975), KENDRICK and CAR MIC HAEL (1980). Numerous papers were published by SUTTON, PIROZYNSKY, HUGHES, TUBAKI, GAMS, HOLUBOVÁ-JECHOVÁ, MORGAN-JONES etc. Dematiaceous Hyphomycetes, mainly lignicolous Hyphomycetes, are rather incompletely known in Hungary. No comprehensive work dealing with this fungus group has been published in Hungary, but sporadic data can be found in several papers. These data are usually reported in papers concerned with the whole fungus flora of given area. Lignicolous and some other saprohytic Hyphomycetes data can be found in the following publications: MOESZ (1941, 1942), of which the latter one is a beautifully illustrated work presenting the fungus flora of Budapest and its environs; L.

HOLLÓS examined the fungi of two Hungarian towns (Kecskemét and Szekszárd) and their country-side (1913, 1933). Numerous papers were published about the fungi of the Mecsek Mts and Villányi Mts. by A. VASS and S.TOTH. A short paper was published on the fungi of the Ocsa Nature Conservation Area (GÖNCZÖL & RÉVAY 1981), and one paper has been prepared on the fungi of the Kiskunság National Park (GÖNCZÖL & RÉVAY 1983, in manuscript). V.

HOLUBOVÁ-JECHOVÁ, while attending the Seventh European Mycological Congress held in Hungary in September 1978, made some collecting excursions and collected some lignicolous and other saprophytic Hyphomycetes, and duly reported these data (HOLUBOVÁ-JECHOVÁ 1979). In my previous paper attention has been focused on the leaf substrate of the Hyphomycetes inhabiting forest litter (GÖNCZÖL & RÉVAY 1983). Although together with the litter-leaf samples woody components of the forest litter were also collected, only Ascomycetous data have been reported so far (RÉVAY 1984). This paper presents some data of lignicolous Hyphomycetes of the dead components of the woody litter. The material of the species enumerated below was collected by the author and her colleague, J.

GÖNCZÖL. The examined material is deposited in the Mycological Herbarium of the Hungarian Natural History of Museum in Budapest. MATERIAL AND METHOD The collecting sites are in the Börzsöny Mts along the mountain stream Morgó-patak, the
