Současně došlo i ke změně názvu časopisu na Czech Mycology. Redakce přijímá články v angličtině, případně němčině či francouzštině. Předpokládáme, že budeme vydávat čtyři čísla ročně. Hlásíme se i nadále k tradici české a československé vědecké mykologie, jejíž publikační platformou byla od roku 1947 Česká mykologie, a jsme odhodláni v tradici pokračovat. Mykologům, kteří chtějí publikovat výsledky svých výzkumů česky nebo sloven ský, nabízíme prostor v Mykologických listech, které vydává rovněž Česká vědecká společnost pro mykologii. Redakční rada se omlouvá za zpoždění vydání prvního čísla a vyzývá k publiko vání v Czech Mycology. EDITORIAL Czech Mycology is a continuation of the journal Česká mykologie, which has been published in the years 1947-1993. Czech Mycology is an international scientific journal publishing papers in all aspects of mycology, including taxonomy, ecology, physiology and mycofloristics as well as mycological topic in forestry, agriculture and medicine. Publication in Czech Mycology is open to members of the Czech Scientific Society for Mycology and non-members. Czech Mycology will publish full length papers and short communication reporting original research which makes a significant contribution to mycology. Review articles are also welcome. Manuscripts are to be submitted in English, German or French. 1 I C zech m y c o l . 47 (1), 1993 ■ Veramyces, a new hyphomycete genus from Kumaon Himalayas ■ C. V.

(1993): Veramyces, nový rod hyfomycetů z Kumaonských Himálají I Czech Mycol. 47: 3-5 ■ Je popsána fialidická synanamorfa oedemiového stadia druhu Thaxteria phaeostroma (Dur. ■ et Mont.) Booth, podle sběru z odumřelých větviček sbíraných v Kilbury, údolí Naini, U.P. ■ v Kumaonských Himálajích. Fialidická forma je považována za nový rod Veramyces a druh H Veramyces elagans. ■ This paper deals with the discovery and description of a phialidic synanamorph of I the Oedemium state of Thaxteria phaeostroma (Dur. & Mont.) Booth. A collection I assignable to this fungus was made by the author from Naini Tal, Uttar Pradesh H in the Kumaon Himalayas in India. Apart from Oedemium conidiophores and I conidia, the fungus was connected to a phialidic synanamorph; it also produced I dark brown multicellular bodies (? gemmae). The following is a description of the I fungus. I Colonies brown to black, effuse, velvety. Mycelium composed of stout, branched, I septate hyphae 8-12 pm wide. Branches dichotomous, often later appearing subdi- ■ chotomous; ultimate branches setose, septate, acicular and pointed, or non-setose, I cylindrical, dark brown, smooth, up to 400 pm long, 8-12 pm wide. Conidiogenous I cells integrated, apical, swollen, smooth, polyblastic, up to 27 x 15 /im in size. I Conidia solitary, dry, developing simultaneously or successively on the conidio- I genous cell (ampulla), ovoid, 1-2-euseptate, smooth, 19-23 pm long, 10-11 pm wide. I Philophores arising from hyphae, lateral, simple, erect, straight or flexuous or I curved, brown, stout, smooth, septate, up to 200 pm long, 9-12 pm wide, bearing a I terminal cluster of branches and phialides. Branches or phialides arising from below I septa and forming a cluster thereon; branches 0-2-septate, 19-23 /im long, 5-6 pm I wide. Phialides terminal or lateral, lageniform, broad below, with conspicuous I collarette, pale to golden brown, smooth. Conidia slimy, small, cylindric-bacillar, I one-celled, hyaline, smooth, 3.0 x 1.5pm. C zech m y c o l . 47 (1), 1993 H Multicellular ‘gemmae’ common, formed mostly terminally on hyphae, sometimes H intercalary, due to swelling of hypha or hyphal tips followed by branching and H septation in a complex way; ‘gemmae’ irregular in shape, nondeciduous, 48-80 x H 44-72 pm, often germinating to produce germ tubes from one or more cells. H The fungus is easily identifiable as the Oedemium state of Thaxteria phaeostroma H (Dur. & Mont.) Booth. As far as known to me, a phialidic synanamorph has not so H far been reported for this taxon. Also, I know of no phialidic genus in which this H can be accommodated. A new genus Veramyces is proposed here to accommodate H The generic name is in honour of Dr. Věra Holubová-Jechová, distinguished for H her work on many Dematiaceous Hyphomycetes and on tropical microfungi. Her B recent demise is a great loss to tropical mycology. H Veramyces Subramanian anamorph gen. nov. I Dematiaceous hyphomycete producing phialidic conidia. Conidiophores simple, H brown, septate, terminating in a cluster of short branches and characteristic I phialides. Phialides terminal or lateral, single or forming clusters, golden brown, I lageniform, with distinct collarette. Conidia slimy, solitary, one-celled, hyaline, I cylindrical to bacillar. I Synanamorph: Oedemium I Hyphomycetes dematiacei conidia phialidica producentes. Conidiophora simpli- I cia, brunnea, septata, in fasciculos ramorum et phialidum terminata. Phialides ter- I minales vel laterales, aureo-brunneae, lageniformes; collare (“collarette”) distincto. I Conidia mucosa, solitaria, unicellularia, hyalina, cylindrica vel bacillaria. I Species typica: Veramyces elagans Subramanian I Veramyces elagans Subramanian sp. nov. anamorpha. I Coloniae brunneae vel atrae, effusae, velutinae. Mycelium ex hyphis ramosis, I septatis, 8 - 1 0 pm latis compositum; ramis dichotomis, saepe posterius manifeste I subdichotomis; rami terminales setosi, septati, aciculares vel acuminati vel non- I setosi, cylindrici vel ad apicem rotundati. Setae usque ad 330 pm longae, 8-9 pm I latae. Conidiophora simplicia, erecta, recta, flexuosa vel curvata, brunnea, laevia, I septata, usque ad 200 pm longa, 9-12 pm lata, in fasciculis ramorum et phialidum I terminata. Rami laterales, subseptati, 0-2-septis, 19-23 pm longi, 5-6 pm lati. I Phialides terminales, vel laterales vel sub septis ortae, lageniformes, ad basim in- I crassatae, longicolles, aureo-brunneae, leaves, 15-20 pm longae, ad basim 4.5-6.0 pm I latae vel ad apicem 1.5 pm latae.
