LignicolousHyphomycetes from Czechoslovakia 1.Brachysporium

Four species of the genusBrachysporium Sacc. emend.Mason etHughes are treated in this paper from Czechoslovakia:B. nigrum (Link)Hughes,B. obovatum (Berk.)Sacc. and two new species,B. abietinum Hol.-Jech. andB. brevius Hol.-Jech.     

Première découverte d’un squelette de Channidae (Poisson téléostéen) dans le Miocène inférieur d’Illerkirchberg, près d’Ulm (Wurtemberg, Allemagne)

A skeleton of a Channid fish is reported for the first time from the European Lower Miocene. Because of the lack of any appropriate diagnostic character, it is nevertheless impossible to determine if it belongs either to the Asiatic genusChanna Scopoli or to the African one,Parachanna Teugels &Daget. For this reason, its palaeobiogeographical significance remains unclear. Otoliths (sagitta) that very likely belong to the same Channid species have been described from Illerkirchberg asChanna elliptica (vonSalis). They are compared to the sagitta from recent species of the generaChanna (Scopoli) andParachanna (Teugels &Daget). Their morphological characters are intermediate between those characterizing the sagitta of both genera.     

New chromosome counts in nine endemic species from Iran

Original meiotic chromosome counts are presented for nine endemic species in seven families of Angiosperms from Iran including:Arum giganteum Ghahr. (Araceae) (n=14),Caccinia actinobole Bunge (Boraginaceae) (n=8),Delphinium aquilegifolium (Boiss.)Bornm. (Ranunculaceae) (n=8),Diplotaenia damavandica Mozaff., Hedge etLamond (Apiaceae) (n=11),Gypsophila caricifolia Boiss. (Caryophyllaceae) (n=17),Iphiona arachnoidea (Boiss.)Anderb. (Asteraceae) (n=9),Moltkia gypsacea Rech. f. etAellen (Boraginaceae) (n=20),Onobrychis gaubae Bornm. (Fabaceae) (n=8) andOnosma platyphyllum Riedl (Boraginaceae) (n=9). Eight counts are reported for the first time. Furthermore, the previous chromosome count forIphiona aracnoidea is corrected. Based on cytological data the species status ofMoltkia gypsacea is confirmed; it is not merely synonymous withM. coerulea (Willd.)Lehm. The basic chromosome number n=11 is reported in the genusDiplotaenia for the first time.     

A revision of the genusOlpitrichum Atk

A revision of the genusOlpitrichum Atk. was undertaken, revealing three species:O. macrosporum (Farlow exSacc.)Sumstine,O. patulum (Sacc etBerl.)Hol.-Jech. andO. tenellum (Berk. etCurt)Hol.-Jech.O. macrosporum andO. tenellum occur on decayed cotton bolls,O. patulum on dead rotten wood and bark. Aspergilliform phialosporous state has been found inO. macrosporum andO. patulum.     

The correct generic and specific name for “Acremoniella atra”

Acremoniella atra auct. is taxonomically identical withHarzia acremonioides (Harz) Cost. which is the type of the genusHarzia. Harzia Cost. 1888 must replace the illegitimate nameAcremoniella Sacc. 1886. Two new combinations—Harzia velata (Onions etJones)Hol.-Jech. andHarzia verrucosa (Togn.) Hol.-Jech. are proposed.     

LignicolousHyphomycetes from Czechoslovakia 2.Bactrodesmium

Six species of the genusBactrodesmium M. C. Cooke are described in this paper from Czechoslovakia:B. betulicola M.B. Ellis,B. obovatum (Oudemans) M.B. Ellis,B. spilomeum (Berk. etBr.)Mason etHughes including three new speciesB. globosum Hol.-Jech.,B. pyriforme Hol.-Jech. andB. submoniliforme Hol.-Jech.     

Contribution to the knowledge ofEchinodorus macrophyllus (Kunth)Mich. andE. scaber Rataj from tropical America

The paper deals with the taxonomy and geographical distribution of the two species of the genusEchinodorus whichFassett (1955) did not work up satisfactorily in his revision i.e.Echinodorus macrophyllus (Kunth)Mich. whichFassett does not quote at all, andE. scaber Rataj whichFassett mistook forE. muricatus Griseb. Further a new variety and the diagnoses of hybrids, among whichE. punctatus Mich. is included, are cited.     

Validation and redescription ofOryctina (Loranthaceae)

The formerly obscure genusOryctina v.Tiegh. is redescribed and validated. It is shown to include two species, an old one, previously known asOryctanthus scabridus Eichl., nowOryctina scabrida (Eichl.) v.Tiegh., and a new one,Oryctina subaphylla Rizz., both from Brazil.     

The arthropodBundenbachiellus giganteus from the Lower Devonian Hunsrück Slate, Germany

The large Hunsrück Slate arthropodBundenbachiellus giganteus (Broili, 1929) has been interpreted as a myriapod, a possible arthropleurid, and most recently as a distorted specimen of the arachnomorph arthropodCheloniellon. The Single specimen lacks the head region and is characterised by a narrow trunk bearing a series of biramous appendages with a segmented endopod and filamentous exopod. A reinvestigation demonstrates that it is not referable toCheloniellon but represents a distinct taxon of whichEschenbachiellus wuttkensis Briggs &;Bartels, 2001, also based on a Single Hunsrück Slate specimen, is a junior synonym. Minor features ofStürmer &;Bergström’s (1978) reconstruction ofCheloniellon, which were based on the holotype ofBundenbachiellus giganteus, are revised.
