“…Sebacina has been considered to be closely related to wood-decaying Exidia species (Wells, 1994). However, the recent molecular systematic study of Weiss & Oberwinkler (2001) suggests that the Sebacinaceae is phylogenetically distinct from Exidia and from the rest of the Auriculariales.…”

“…Epulorhiza is a member of the diverse-form genus Rhizoctonia, which includes most fungi found as mycorrhizal associates of orchids (Smith & Read, 1997). Epulorhiza species have been recovered from many European and North American orchids, but most of these appear to be related to Tulasnella rather than Sebacina (Anderson, 1996), and Sebacina is thought to be only distantly related to Tulasnella (Wells, 1994). The North American MHP orchid Hexalectris spicata associates specifically with fungi that have quite similar ITS sequences to the two Neottia fungi (Taylor, 1997;D.…”

Symbiotic germination and development of the myco‐heterotrophic orchid Neottia nidus‐avis in nature and its requirement for locally distributed Sebacina spp.

Summary• Symbiotic germination and development of the fully myco-heterotrophic orchid Neottia nidus-avis were studied in 'packets' of seed placed adjacent to, or at varying distances from, adult plants in a Fagus sylvatica woodland.• The distribution and identity of the fungal partner(s) of N. nidus-avis were investigated by internal transcribed spacer (ITS)-restriction fragment length polymorphism (RFLP) and sequence analysis of part of the 28S gene in fungal DNA extracted from adult plants from the UK and Germany, and from seedlings germinated in situ .• Germination commenced in the spring, but only in the presence of a specific fungus, and occurred most frequently in plots containing adults of N. nidus-avis . Seedlings grew best in packets in which a large number of seeds germinated. Adults and seedlings of UK origin contained the same fungal partner whose 28S sequence most closely matched Sebacina dimitica. Plants of German origin contained a closely related, but distinct, fungus.• The results provide the first definitive chronology of the development of N. nidus-avis and establish its critical dependence upon, and specificity for, the locally distributed Sebacina -like fungus that is required for germination and growth.

“…Septal pore morphology studied in many basidiomycetes (see Oberwinkler, 1985 and the references therein) continues to play an important role in the arrangement of these taxa (Wells, 1994). These studies indicate that characteristics of septal pore apparatus are conserved and indicative for natural relationships.…”

Septal Pore Apparatus of the Smut Ustacystis waldsteiniae

1995

Abstract:The septal pore apparatus in intercellular hyphae of Ustacystis waldsteiniae was analyzed by serialsection electron microscopy using chemically fixed and high pressure frozen/freeze substituted samples. Septa have a central "simple" pore with rounded, nonswollen margins. However, the pore apparatus is a highly complex structure, differing significantly from that found in "simple"-and complex-septate basidiomycetes. Three features are typical: 1) the pore canal is traversed by two symmetrically arranged bands, 2) a dome shaped membranous cap, intimately attached to the plasma membrane, encloses the pore on both sides, and 3) a thin electron transparent layer and a layer of medium electron density cover the cytoplasmic side of the membranous cap. From our observations of septal pore morphology we suggest a general absence of transport of organelles including ribosomes through the pore.

The structural and biochemical database for fungi (Celio et al 2006) aims to capture several of these characters in a comprehensive manner.…”

A brief survey towards an understanding of evolution of Basidiomycota in the last five decades is given. Between 1960-1990 studies were based mainly on morphology, subcellular structure, biochemistry, physiology and ecology. In the last 20 years, molecular methods have revolutionized the study of taxonomy, systematics, phylogeny, biogeography, population and microevolutionary processes in basidiomycetes. A fundamental improvement in the understanding of evolution of basidiomycetes has been achieved. It is anticipated that numerous new taxa at different taxonomic levels will be recognized based on integrated approaches, and new data will soon provide fascinating insights into the origin, evolution and biogeography of basidiomycetes in the coming years.
