“…Morphologically, it produces synnemata with a capitate bulbil-like head proliferating about seven times to yield new bulbils. The species seems to be widely distributed (Okada et al, 1998 ).…”

Digging Up the Roots: Taxonomic and Phylogenetic Disentanglements in Corticiaceae s.s. (Corticiales, Basidiomycota) and Evolution of Nutritional Modes

Corticiaceae is one of the traditional families of the Agaricomycetes and served for a long time as a convenient placement for basidiomycetes with a resupinate, corticioid form of fruiting body. Molecular studies have helped to assign many corticioid fungi to diverse families and orders; however, Corticiaceae still lacks a phylogenetic characterization and modern circumscription. Here, we provide the first comprehensive phylogenetic and taxonomic revision of the family Corticiaceae based on extensive type studies and sequences of nLSU, ITS, IGS, nSSU, and mtSSU regions. Our analyses support the recognition of ten monophyletic genera in the Corticiaceae, and show that nutritional mode is not a robust basis for generic delimitations in the family. The genus Mycobernardia and the species Corticium thailandicum, Erythricium vernum, and Marchandiomyces allantosporus are described as new to science, and five new combinations are proposed. Moreover, ancestral character state reconstruction revealed that saprotrophy is the plesiomorphic nutritional mode in the Corticiaceae, while several transitions have occurred to diverse nutritional modes in this family. Identification keys are provided to the genera in Corticiaceae s.s. as well as to the species in Corticium, Erythricium, Laetisaria, and Marchandiomyces.

“…& Curtis) Sacc. The morphology and dispersal strategy of Decapitatus recalls somewhat the genus Tretopileus Dodge (1946) that forms "pilei" which fall off and act as propagules (termed bulbils by Okada & al., 1998). In the latter case, the differentiation between the normal basidiome and the anamorph ["gemmifer" (Buller, 1934), "cabecitas" (Wellman, 1950;Salas & Hancock, 1972), "stilboid" structure (Singer, 1951;Seifert, 1985), "cephalosus" (Watling, 1979), or "apokybium" (Cl6menqon, 1997)] is so complete that mycologists have never mixed the two nomenclaturally, or bothered to name a genus for the Stilbunm flavidum anamorph despite the abundance of descriptive vernacular names coined in compensation.…”

“…& Curtis) S. Hughes & Deighton in Deighton (1960), is quite different, being strongly melanised, and continually regenerating its cephalosus. Okada & al. (1998) reported that Tretopi/eus sphaeromorphus was a basidiomycete, thus far shown to be closer to the Aphyllophorales (using 18S data) than to the agarics, but its pileate form does suggest an agaric relative.…”

International Association for Plant Taxonomy (IAPT) is collaborating with JSTOR to digitize, preserve and extend access to Taxon. Summary Redhead, S. A., Seifert, K. A., Vilgalys, R. & Moncalvo, J.-M.: Rhacophyllus and Zerovaemyces-teleomorphs or anamorphs? -Taxon 49: 789-798. -ISSN 0040-0262.The originally monotypic genus Rhacophyllus was conceived for an agaric-like fungus that bore sheets of miniature sclerotium-like bodies (lysomeres) in place of lamellae. Subsequently it was demonstrated that a "normal" Coprinus-like teleomorph exists as an alternative state (morph). Following this discovery, most authors have treated Rhacophyllus as an anamorph. Ontogenetic studies indicate that the Rhacophyllus state is a variation on basidiome production. Rhacophyllus apparently was rediscovered and redescribed as a new genus Zerovaemyces, for which a new family, Zerovaemycetaceae, and a new order, Loculomycetes, were also described, all as teleomorphs. Nomenclatural application of these names are analysed, and it is concluded that Rhacophyllus (and Zerovaemyces, Zerovaemnycetaceae) are best considered to be nomina anarmorphosium. These decisions affect the naming of other taxa newly resolved molecularly. An analogous second case of modified basidiomes involves the anamorph Decapitatus gen. nov., described here for the well-known gemmiferous state of Mycena citricolor, Decapitatus flavidus comb. nov. (= Stilbum flavidum).

Ovipoculum album, a new anamorph with gelatinous cupulate bulbilliferous conidiomata from China and with affinities to the Auriculariales (Basidiomycota)

et al. 2010

An anamorphic fungus forming laterally attached, cupulate, gelatinous, hyaline to white conidiomata producing bulbils from clamped hyphae was collected on dead bamboo culms in southwestern China. Though the conidiomatal morphology is similar to that of Dacryoscyphus (anamorphic Dacrymycetales), microscopical and DNA sequence analysis revealed a phylogenetic relationship with members of the Auriculariales. The taxon is therefore described as new and separate from Dacryoscyphus. It is also distinct from other recognized bulbilliferous basidiomycetes. Two recently described anamorphic Dacrymyces species, D. pinacearum and D. subarcticus, were restudied and are transferred to Dacryoscyphus.
