Die Forstwirtschaft hat unlängst realisiert, dass die Förderung und der Er- halt natürlicher Totholzvorkommen von immenser Wichtigkeit für Ökosystemdienst- leistungen sind, nicht zuletzt, weil Totholz ein Reservoir für biologische und funktionel- le Diversität darstellt. Das Hauptziel dieser umfassenden Studie bestand zum einen in der Untersuchung des Einflusses unterschiedlicher Waldbewirtschaftungsstrategien auf die mikrobielle Diver- sität an Totholz zweier in Deutschland forstlich relevanter Baumarten Fagus sylvatica and Picea abies. Zum anderen sollte der Zusammenhang zwischen baumartspezifischen physikalischen und chemischen Parametern und den damit verbundenen Veränderungen der mikrobiellen Diversität aufgeklärt werden. Ein nicht unerheblicher methodischer Fokus lag hierbei in der Verknüpfung moderner molekularbiologischer Techniken („Next-generation sequencing“) mit klassischer, auf Observation basierender Feldmyko- logie.

This fungal flora has a richness of 752 species belonging to the class of Basidiomycetes, divided into 19 orders, 62 families and 165 genera. The present catalog of rifain fungal flora constitutes a large contribution to the knowledge of the biodiversity of fungi in the Moroccan Rif. The species are completed and updated with new science and arranged according to the main mycological classification. However, it is certain that the attentive and methodical explorations in the Rifain forests could be the origin of new discoveries for the fungal flora of Morocco.

Etee adaeet of the keratokonus can cause corneal perforation, destroying the vision. To avoid this, corneal transplant is required to save the eye.

Nowadays, cross-linking is the only procedure used to halt the natural progression of keratokonus, Studied and applied for the first time at Dresden University, a great number of clinical studies supported its efficacy in halting the progression of keratokonus.

Both species are fully described, illustrated, and compared with similar and/or closely related taxa. Key words: fungi, agarics, systematics, taxonomy Introduction Our ongoing investigation of California species of Mycena (Perry 2002; Perry & Desjardin 1999) has revealed the presence of two previously unnamed taxa: Mycena nivicola and M. bulliformis, herein proposed as new species. Prior to our investigation, studies in the genus from California were limited to those of A.H. Smith’s (1947) monograph of Mycena in North America, Harkness & Moore’s (1880) Catalogue of Pacific Coast Fungi, those species included in Murrill’s (1916) North American Flora and several additional references and field guides (Lincoff 1981; Redhead 1982; Smith et al. 1979).

    Ecology of Macrofungi in the Beech Woods of the Šumava Mountains and Šumava Foothills

    Ecology of macrofungi in the beech woods of the Šumava mountains and Šumava foothills Ekologie makromycetů v bučinách Šumavy a Šumavského podhůří Jan H o le c The fungi of the order Agaricales s. 1. and several families of ungilled fungi and gasteromycetes were studied in the beech woods of the southeastern part of the Sumava mountains and Sumava foothills (Czechoslovakia). Altogether, 230 species were recorded on 8 permanent plots (50 x 50 m) during the years 1988 - 1990. The terrestrial fungi were closely associated with a particular layer of the surface humus and substrate, and the lignicolous fungi were associated with wood in various stages of decay. The occurrence of mycorrhizal fungi was influenced above all by the mycorrhizal partner, altitude, and climate. The species composition, number of mycorrhizal and terrestrial species on the individual plots, and their share were determined by the humus type, microrelief, and the thickness of the detritus layer. The occurrence of lignicolous fungi was in close relation to the degree of naturalness of the wood, substrate diversity of the plot and the mesoclimate. The results are summarized in the mycosociological tables and compared by the use of cluster analysis and diagrams. V bučinách jihovýchodní části Šumavy a Šumavského podhůři byly studovány houby rádu Agaricales s. 1. a dále několik čeledí nelupenatých a brichatkovitých hub. Na 8 trvalých plochách o velikosti 50 x 50 m jsem během vegetačních sezón v letech 1988 - 1990 nalezl celkem 230 druhů hub. Terestrické druhy byly těsně vázány na určitou vrstvu nadložního humusu a substrát v této vrstvě, lignikolní druhy na dřevo v různých stadiích rozkladu.
