... the restriction of ecological niches. The highest range of di ff erent substrates and habitats can be found in middle canopy layers, which also exhibit the most diverse mycota. Here, exposed and shaded areas occur close to eachother; thin, recently decayed twigs co-exist with thick branches in later stages of decay. Many lignicolous fungi seem to respond to the diameter of the sub- strate as it was mentioned earlier by Helfer & Schmid (1999). Our preliminary results additio- nally correlate with faunistical reports which al- so display the central canopy as the most diverse habitat concerning species richness and substrate type. This study of diversity and substrate specifici- ty of wood decay fungi revealed strong di ff erences between tree species. Species-specific structures of tree crowns as well as morphological and bioche- mical properties of the wood (incl. phloem fibres and bark) surely account for the di ff ering numbers of fungal species. Wood of T. cordata was coloni- sed by the largest number of fungal species. This seems plausible as it is poor in growth-restricting metabolites. Because of its low density, it possesses a good hygroscopicity which most probably facili- tates fungal establishment. Insects, which play an important role in the dispersal and establishent of xylotrophic fungal species ( Dix & Webster 1995) easily penetrates the soft wood of linden trees. Quercus robur and Fraxinus excelsior possess very hard wood that is rich in tanning agents, which could be restrictive to the colonisation of fungi. The large species richness on Q. robur can be explained by a high structural complexity of its tree crowns. Measurements of light intensi- ty (PAR) demonstrated more heterogenous light patterns than in F. excelsior crowns ( Horchler , pers. comm.). The variability of small-scale ha- bitats therefore increases resulting in more pos- sibilites for niche partitioning among the fungal organisms. The first description of this species was made by J. Hedwig (1787-89), E. M. Fries (1822) placed it in the genus Patellaria (lat. patella : cup, bowl; atra : black). From today’s systematical point of view, the genus is eponymous for family and order (Patellariaceae, Patellariales) and belongs to the bitunicate discomycetes. Confusions during iden- tification are mostly due to species of the genus Patellariopsis and with lichens of the Lecanora- ceae, who produce black-bordered apothecia. A unique morphological-chemical feature of Patella- ria atrata are the bitunicate asci with an apical apparatus showing no amyloid reaction ( Patellari- opsis with unitunicate asci and an amyloid apex).

Prefered substrate were free phloem fibres, in three cases the apothecia emer- ged on the naked wood, too. The decayed twigs, between 1 und 2,5 cm in diameter, without visible coverage of cryptogamic epiphytes were classified as strongly decayed (white rot, ca. 1/2 of the dia- meter clearly decayed). The sampling height was between 11 and 28 m, six sample points were sha- ded, two were located in the upper, strongly expo- sed canopy. Several times, the species was found in close association to Rabenhorstia cf. tiliae (Fungi imperfecti), which is the anamorph of Hercospora . Patellaria and Rabenhorstia apparently have simi- lar ecological requirements and probably compete against each other. The crane site is characterised as a for- mer oak and elm rich floodplain forest ( Querco- Ulmetum minoris Issler 1924, = Fraxino-Ulmetum [R.Tx.1952] Oberd. 1953). Due to the lack of re- gular innundations for the last ca. 70 years, suc- cession has tended towards a forest rich in Acer pseudoplatanus L. and Fraxinus excelsior L.

Hot desert regions are undoubtedly challenging to fungal survival on the Arabian Peninsula. Fungi are, however, recognized as the most stress-resistant organisms among all eukaryotes, which could be a result of the rapid evolution of distinct species. Our current understanding of these microorganisms is derived from studies examining only a fraction of the overall fungal diversity. Therefore, further studies are needed to understand the diversity of fungi in desert regions. This paper highlights the taxonomy of several unusual fungal genera collected in a range of aquatic and terrestrial environments in Oman. These taxa were identified based on phylogenetic analyses of nuclear ribosomal DNA (rDNA) (LSU, SSU and ITS) and protein-coding genes (TEF, RPB2 and TUB), plus morphological comparisons. Phylogenetic analyses, including the presently recognized genera in Patellariales resulted in splitting the order into four clades in Dothideomycetes. The new family Holmiellaceae and new order Holmiellales are introduced to include Holmiella. Species of Homortomycetaceae form a well-supported and distinct clade and raise it to Homortomycetales ordo novus. Omania (Halojulellaceae), Desertiserpentica (Lophiostomataceae) and Montanitestudina (Testudinaceae) are described as novel genera in Dothideomycetes. A synnematous hyphomycete with basidiomycetous affinity (Corticiales) was also identified and described as Basidiodesertica. Additionally, an asexual morph was observed for Holmiella junipericola; Patellaria quercus is synonymized under P. atrata, and seven new species are described.
... In forests with recent disturbances, like strong storms or selective cuttings, the number of FWD is increasing with fresh pieces. In a German forest, numerous fungi colonized canopy branches, the majority of them in the middle and lower canopy, while in the upper canopy, 60% of total records were dominated by species from only four genera (Unterseher et al., 2003). Thus, the new-fallen fine pieces -especially coming from the upper canopy, will have a lower fungal richness compared with undisturbed forest stands, where the FWD comes from all canopy levels. ...
Aim of the study: The main objective of this study was to find the factors which best explains the wood-inhabiting fungal species’ richness in beech and oak-dominated forests.
Area of study: We focused on broadleaved and mixed forests found in Northeastern Romania.
Materials and methods: 59 plots were randomly set up in broadleaved and mixed forest stands, in which vegetation structure, composition, and topoclimatic factors were quantified along with wood-inhabiting fungal richness. Generalized linear models were used to characterize relationship between fungal diversity and biotic and abiotic factors.
Main results: 374 taxa were identified, with numerous species found to cohabitate, the highest sharing being between Fine Woody Debris and Downed Coarse Woody Debris. The best predictors of total diversity were related to the substrate, management, stand structure, and macroclimate. Higher volumes of logs and large branches in various decay stages increased fungal richness. The same effect was found in diverse forests, with large snags. Macroclimate and topoclimate positively influenced diversity, through De Martonne Aridity Index and snow cover length, both indicating macrofungi preferences for higher moisture of substrate. Silvicultural interventions had an ambivalent effect to fungal diversity, phenomenon observed through stump numbers and proportion.
Research highlights: Particular environmental characteristics proved significantly important in explaining different wood-inhabiting fungal richness patterns. Substrate-related variables were the most common ones found, but they were closely linked to climate and forest stand variables.
... In Fraxinus, Quercus and Tilia high canopies, Unterseher et al. (2003) found out that 60% of all records were represented by Cryptosphaeria, Diatrypella, Nitschkia, Peniophora genera. As the height lowered, the fungal lignicolous diversity increased. ...
... As the height lowered, the fungal lignicolous diversity increased. Still, no less than 85 species were found in tree canopies [Unterseher et al., 2003], which may continue the decay on the fallen woody debris. ...
Lignicolous macromycetes are of great importance for the functionality of forest ecosystems. These fungi work as the main carbon reintegrating agents in the soil or as keepers of forest vitality. Under the biotic and abiotic changes, fungi species reacts differently, the main effects being seen at the level of numbers and composition structure of fungal communities. In the context of human actions on forest ecosystems, numerous studies show the detrimental effects on lignicolous mycodiversity, at both European and local levels. In order to protect mycodiversity, it is vital to understand the way the relation between fungi and forest works.
... The distribution and diversity of decay fungi not only varies between tree species, but also with location in the canopy; twigs and branches (<6 cm diam.), mostly Fraxinus excelsior, Tilia cordata, and Quercus robur, collected from canopy of deciduous trees in Germany, contained different taxa (indicated by presence of fruit bodies) at different heights (Unterseher et al. 2003). The upper canopy had the least species, four genera (Cryptosphaeria, Diatrypella, Nitschkia, and Peniophora) forming 60% of all records. ...

The Dothideomycetes include several genera whose ascomata can be considered as apothecia and thus would be grouped as discomycetes. Most genera are grouped in the family Patellariaceae, but also Agrynnaceae and other families. The Hysteriales include genera having hysterioid ascomata and can be confused with species in Patellariaceae with discoid apothecia if the opening is wide enough. In this study, genera of the family Patellariaceae were re-examined and characterized based on morphological examination. As a result of this study the genera Baggea, Endotryblidium, Holmiella, Hysteropatella, Lecanidiella, Lirellodisca, Murangium, Patellaria, Poetschia, Rhizodiscina, Schrakia, Stratisporella and Tryblidaria are retained in the family Patellariaceae. The genera Banhegyia, Pseudoparodia and Rhytidhysteron are excluded because of differing morphology and/or molecular data.
