1-septate, with a dark brown band at the septa, 9-10 x 3-4 jum. In Europe it is a common lignicolous hyphomycete but only some data are known from Hungary. HOLUBOVÁ-JECHOVÁ (1979) reported it from rotten wood of Betula sp. and Fagus siivatica

This fungus was found in Hungary on one occasion and reported as Endophragmia alternata Tubaki & Saito, growing on strobili of Alnus glutinosa (GÖNCZÖL & RÉVAY 1983). - Collected on spruce cone of Picea abies from the stream Pénz-patak in the Biikk Mts., 30.5.1985.

; 29.3.1985., 29.8.1985. Xylomyces chtamydosporis Goos, Brooks et Lamore, Mycologia, 69: 280, 1977. (Pl.V. Fig.l.) Xylomyces was described as a new genus GOOS, BROOKS et LAMORE (1977) from dead, submerged wood, collected in the Saugaaicket River in the Rhode island. It was characterised by large, 100450 x 35-42jum, fusiform, blackish brown chiamydospores, which are solitary or in chains.During our studies on the wood-innabiting iüngi of both terrestrial and aquatic habitats, this interesting fungus it was found on submerged wood collected from a mountain stream. Mycelium immersed and superficial, composed of dark brown, anastomosing hyphae, 5-13 Aim in diam. Chiamydospores intercalary, in chains of 2 to 6-7, with 5-10 septa, fusiform, first hyaline then becoming dark brown, 200-500 x 37-43 Aim. This is the first record of X. chiamydoaporis from Hungary and to my knowledge this collection represents the first Euiopean record of this species. - Collected on dead wood of Fagus siivatica, from the stream Pénz-patak in the Biikk Mts., 30.5.1985., 7.10.1985. In this paper 36 recoros of 25 fungus species belonging to 20 genera are listed. Of these
