THE GENUS BASIDIODENDRON
Abstract
Sebacina, Exidiopsis, and Basidiodendron, three genera of the resupinate tremellaceae, are recognized. Sebacina, based on Thelephora incrustans Pers. ex Fries, is retained (in sensu stricto). Exidiopsis, established for Exidia effusa Bref., is accepted as a genus. The taxon Bourdotia, originally created by Bresadola in 1908 as a subgenus with Sebacina (Bourdotia) galzinii as the type and in 1913 elevated by Bresadola and Torrend to generic rank, is proposed as a subgenus of Exidiopsis. Since Bourdotia galzinii is the type of Bourdotia, the generic name Basidiodendron created by Rick in 1938 in order to accomodate B. luteo-griseum is reinstated for the arid-reticulate gloeocystidiate species formerly included in Bourdotia. Two subgenera of Basidiodendrcn are recognized, namely the type subgenus Basidiodendron established for B. luteo-griseum Rick and Asarcogloea subg. nov. based on Sebacina pini Jacks. & Martin. The type subgenus Basidiodendron includes six species. In Asarcogloea, there are four species involved. Two of these, B. subreniformis sp. nov. and B. nodosa sp. nov., found in Ontario inhabiting decaying wood, are described for the first time. Taxonomic keys and illustrations are included for these species.
... Il a été créé avec Basidiodendron luteogriseum Rick comme espèce type (RiCk, 1938) sans évoquer le cloisonnement des basides (donk, 1958), puis amendé lors du démembrement du genre Bourdotia (Bres.) Trotter (LuCk-aLLen, 1963). À cette occasion, le type a été rapproché de Basidiodendron eyrei (Wakef.) ...
... Macroscopiquement, les Basidiodendron présentent des basidiomes étalés, résupinés, à marge indéterminée (LuCk-aLLen, 1963), à surface hyménophorale lisse, rarement tuberculée, devenant crustacée, poruleuse (weLLs & RaitviiR, 1975) ou à peine visible (kotiRanta & saaRenoksa, 2005). Parmi les Auriculariales, ce genre se distingue par deux caractéristiques microscopiques originales. ...
... Tout d'abord la présence de gléocystides subcylindriques, flexueuses, à contenu jaune à jaune d'or, jusqu'à brun (weLLs & RaitviiR, 1975), particulièrement visible dans le melzer d'après nos observations. Enfin, pour certaines espèces (LuCk-aLLen, 1963), des basides se forment en bouquets à partir des boucles, se collapsent à maturité, leur croissance progresse perpendiculairement au substrat pour former une longue colonne sinueuse à l'aspect d'arêtes de poisson, appelée hyphes basidiale dans la suite du présent article. Le terme d'involucre a été emprunté à la botanique pour décrire cette structure (eRvin, 1957, p. 120). ...
Plusieurs spécimens très particuliers de Basidiodendron ont été récoltés récemment en Guyane. La structure de leur basidiome et leurs hyphes basales engainées de matière gélatineuse n'ont pas d'équivalent dans ce genre, à ce jour. Ces récoltes permettent de proposer B. gelatinosum, une nouvelle espèce, décrite et illustrée dans le présent article. Abstract Several very peculiar specimens of Basidiodendron have been recently collected in French Guiana. The structure of their basidioma and their basal hyphae embedded in gelatinous matrix have no equivalent in this genus. Based on these collections, we propose to introduce a new species, B. gelatinosum, described and illustrated herein.
... Basidiodendron Rick is a genus of the Auriculariales (Agaricomycetes, Basidiomycota) encompassing 20 accepted species (www.mycobank.org). First introduced by Rick (1938) as monotypic, the genus was re-established by Luck-Allen (1963) for effused wood-inhabiting fungi with gloeocystidia and four-celled, longitudinally septate basidia. The most striking feature of Basidiodendron, however, is a peculiar arrangement of basidia: turgid basidial cells are located at the apices of long, sinuous hyphae covered by shields of collapsed basidia along their whole length. ...
... This trait is unique among the Auriculariales, and it allows morphological differentiation of the genus from other genera of the Auriculariales with gloeocystidia, such as Bourdotia, Ductifera, Exidiopsis s.l. etc. (Luck-Allen 1963;Wells and Raitviir 1975;Wojewoda 1981). The phylogenetic study of the Auriculariales conducted by Weiss and Oberwinkler (2001) showed five Basiodiodendron species in a single cluster, although without statistical support. ...
... Luck-Allen (Wells 1959), and this viewpoint has not been questioned. However, the identity of the latter species was interpreted in different ways (Rogers 1935;Pilát 1957;Wells 1959;Luck-Allen 1963;Lowy 1971;Wells and Raitviir 1975;Wojewoda 1981;Kotiranta and Saarenoksa 2005). In particular, the taxonomic status of Basidiodendron deminutum (Bourdot) Luck-Allen, B. rimulentum (Bourdot & Galzin) Luck-Allen, B. grandinioides (Bourdot & Galzin) Luck-Allen, and Bourdotia mucosa Bourdot & Galzin versus B. eyrei has not been satisfactorily clarified. ...
To date, Basidiodendron luteogriseum, the generic type of Basidiodendron (Auriculariales, Basidiomycota)
has been treated as a synonym of B. eyrei. Our data show they are not conspecific. The identity of other members
of the B.eyrei complex, i.e. B.deminutum and B.grandinioides, is clarified based on morphological and DNA data, and
10 new species are described from Eurasia, as well as from North and South America.
... D. helenae is undoubtedly a member of the Auriculariales but it is very distant from other genera possessing similar morphological characters. The presence of gloeocystidia and almost subglobose spores brings Basidiodendron to mind, but species of the latter genus have thin-walled, shorter, broadly urniform or subglobose basidia, which collapse and form involucre-like structures in older basidiocarps (Luck-Allen 1963, Wells & Raitviir 1975. The sole representative of Bourdotia, B. galzinii, has stalked (petiolate) basidia and a well-developed epihymenial layer consisting of densely arranged hyphidia (Wells & Raitviir 1975, Weiss & Oberwinkler 2001. ...
In total, 7 species of heterobasidiomycetes are reported for the first time from St. Helena. A new genus Dendrogloeon (Auricularilaes) is introduced for the new species D. helenae based on both DNA and morphological data. Saccoblastia media, sp. nova, is the sole representative of the Pucciniomycotina, so far found in the study area. Introduction This paper summarizes the first data on heterobasidiomycetes of St. Helena.
... Our record is new to the Starobilsk gramineous-meadow steppe mycofl oristical region as well as to the whole steppe zone and the plain part of Ukraine. B. rimulentum is a poorly known species known to develop on both coniferous and deciduous wood and that has been reported from France and Norway (Luck-Allen, 1963;Torkelsen, 1997a). ...
Fift een species of corticioid fungi with heterobasidia are recorded from the forests in the middle of the Seversky Donets River basin (eastern Ukraine) from 2007 to 2011. Of them, 11 species are new to Ukraine. Th ey are Basidiodendron rimulentum (Bourdot et Galzin) Luck-Allen, Ceratobasidium cornigerum (Bourdot) D.P.Rogers, Eichleriella deglubens (Berk. et Broome) Lloyd, Exidiopsis griseobrunnea K.Wells et Raitv. subsp. griseobrunnea, Helicogloea lagerheimii Pat., Stypella grilletii (Boud.) P.Roberts, Tulasnella albida Bourdot et Galzin, T. eichleriana Bres., T. pallida Bres., T. saveloides P.Roberts, and T. thelephorea (Juel) Juel. Two of these species, Exidiopsis griseobrunnea and Tulasnella saveloides, are still known to be from very few European regions, even aft er being discovered in Ukraine. Furthermore, 3 species (Basidiodendron eyrei (Wakef.) Luck-Allen, Exidiopsis galzinii (Bres.) Killerm., and Tulasnella violea (Quél.) Bourdot et Galzin) are new to the steppe zone and the plain part of Ukraine. Th anatephorus fusisporus (J.Schröt.) Hauerslev et P.Roberts is reported from Ukraine for the second time. Information on the ecology and distribution of the species is presented. Comments are made on the morphology of the specimens examined and original illustrations are provided for all of the species.
... Basidiodendron species, which also possess cystidia and globose or elliptical spores, are clearly distinguished by their unique hymenial morphology in which basidia are produced in succession on continually extending stalk cells. These stalk cells become sheathed in old collapsed basidia, producing a typical herring-bone effect, well-illustrated by Luck-Allen (1963). Basidiodendron subgen. ...
Ten species currently referable to the tremellaceous genus Exidiopsis are described from Devon, England, together with two Sebacina species, one from the New Forest. Only those species congeneric with the type species are retained in Exidiopsis. Four new genera, Ceratosebacina, Endoperplexa, Microsebacina, and Serendipita are proposed to accommodate the rest. Three new species are described: Endoperplexa dartmorica, Serendipita orliensis, and Serendipita sigmaspora. New combinations are proposed for six British species: Ceratosebacina longispora, Endoperplexa septocystidiata, Microsebacina fugacissima, Microsebacina microbasidia, Serendipita vermifera, and Serendipita evanescens; and for five extra-limital species: Endoperplexa enodulosa, Endoperplexa subfarinacea, Serendipita invisibilis, Serendipita inclusa, and Serendipita interna.
Taxonomy of Basidiodendron caesiocinereum complex is revised based on morphological and molecular methods (with the use of nc LSU rDNA, ITS and TEF1 regions). The basidiospore ornamentation is justified as a key morphological character for the species recognition in the group. As redefined here, B. caesiocinereum is an angiosperm-dwelling species with smooth basidiospores. Bourdotia cinerella and B. cinerella var. trachyspora are proved to represent separate species with warted basidiospores; they are reintroduced as Basidiodendron cinerellum and B. trachysporum. Additionally, eight new species related to B. caesiocinereum are described based on material from Eurasia, North America and Africa, and identity of B. spinosum from Oceania is discussed.
In order to estimate phylogenetic relationships in the Auriculariales sensu Bandoni (1984) and allied groups we have analysed a representative sample of species by comparison of nuclear coded ribosomal DNA sequences, applying models of neighbour joining, maximum parsimony, conditional clustering, and maximum likelihood.
Analyses of the 5’ terminal domain of the gene coding for the 28 S ribosomal large subunit supported the monophyly of the Dacrymycetales and Tremellales, while the monophyly of the Auriculariales was not supported. The Sebacinaceae, including the genera Sebacina, Efibulobasidium, Tremelloscypha, and Craterocolla, was confirmed as a monophyletic group, which appeared distant from other taxa ascribed to the Auriculariales. Within the latter the following subgroups were significantly supported: (1) a group of closely related species containing members of the genera Auricularia, Exidia, Exidiopsis, Heterochaete, and Eichleriella; (2) a group comprising species of Bourdotia and Ductifera; (3) a group of globose-spored species of the genus Basidiodendron; (4) a group that includes the members of the genus Myxarium and Hyaloria pilacre; (5) a group consisting of species of the genera Protomerulius, Tremellodendropsis, Heterochaetella, and Protodontia. Additional analyses of the internal transcribed spacer (ITS) region of the species contained in group (1) resulted in a separation of these fungi due to their basidial types.
Microcycle conidiation is defined as the germination of spores by the direct formation of conidia without the intervention of mycelial growth, as occurs in most normal life cycles. It is a method of asexual spore formation in which the normal life cycle of the fungus is bypassed. Spores formed through sexual reproduction and species with unicellular thalli are not included in microcycle conidiation. The term secondary conidium or secondary spore is usually, but not always, synonymous with microcycle conidiation. In the laboratory various factors, but especially temperature, can induce the microcycle condition in such fungi asAspergillus niger, Penicillium andNeurospora crassa, providing a useful tool for research. Microcycle conidiation has also been reported in a broad range of species in nature, and comprises a normal part of the life cycle in several groups, including the Entomophthorales, Taphrinales, Clavicipitales, Uredinales, Ustilaginales, Tremellales and Exobasidiales. The presence of a microcycle in such fungi undoubtedly provides a survival mechanisn for spores that encounter unfavorable conditions.
Six species of the genus Basidiodendron are reported from Finland: B. caesiocinereum (Höhn. & Litsch.) Luck-Allen, B. cinereum (Bres.) Luck-Allen, B. deminutum (Bourdot) Luck-Allen, B. eyrei (Wakef.) Luck-Allen, B. radians (Rick) P. Roberts and B. rimosum (H.S. Jacks. & G.W. Martin) Luck-Allen. All but B. cinereum are reported for the first time. The most common species in the genus seems to be B. caesiocinereum followed by B. eyrei and B. cinereum. Descriptions and illustrations of each species are given as well as a key to the Finnish species. A few reference collections from Russia are also included.
