A striking species of cyphelloid fungus tentatively identified as a Henningsomyces or Rectipilus was collected in Białowieża virgin forest in Poland since 1962. After search in literature, morphological studies and phylogenetic analyses based on LSU and ITS rDNA sequences, the species turned out to be unknown to science with ≥ 5% difference in LSU...

... adnate to adnexed or broadly emarginate lamellae and not depressed pileus (papillate, umbonate), stipe entirely pruinose-velvety, a duplex pileus trama (the upper half gelatinized and the lower half of thick-walled glassy hyphae), and cheilocystidia with numerous rod-like projections. Heimiomyces species are common pantropical taxa (Singer 1965) that had also been recorded in North America (Smith 1953, Singer 1965, Miller 1968, Horak 1979a, Redhead 1988, Maas Geesteranus & Horak 1995, Corner 1996, Ramírez et al. 2013 (Larsson 2007a, Lebel et al. 2015, Zhao C-L et al. 2016, Leal-Dutra et al. 2020, Karasiński et al. 2023. Basidiome shape is very diverse and there are no obvious synapomorphic traits shared by all Phyllotopsidineae. ...
... The addition of sequences of Aphroditeola and Tectella (and other lineages in the remaining suborders) might be the cause of the different result, suggesting that gaps in the diversity analyzed could affect the phylogenetic (and phylogenomic) results. Karasiński et al. (2023), recovered a significant relationship between Phyllotopsidaceae and a clade formed by the cyphelloid genera Cyphelloporia and Rectipilus, but the correct classification of these genera needs to be further explored analyzing multigene data in the context of the entire suborder Phyllotopsidineae. A new family name might be necessary to accommodate them. ...
... All three genera contain saprotrophic species, mostly lignicolous, and possess clamp connections (Singer 1986, Watling & Gregory 1989, Knudsen 2008a, Vesterholt 2008b, Knudsen & Shiryaev 2012. A corticioid sample identified as Bulbillomyces farinosus seems related to Macrotyphula in some works (Karasiński et al. 2023), but another candidate lineage for this name exists in the Polyporales (Larsson 2007b, Justo et al. 2017. The classification of the monospecific genus Bulbillomyces needs to be confirmed by selecting an epitype, and so its position inside Phyllotopsidaceae is by now doubtful. ...
The phylogenetic position of several clitocyboid/pleurotoid/tricholomatoid genera previously considered incertae sedis is here resolved using an updated 6-gene dataset of Agaricales including newly sequenced lineages and more complete data from those already analyzed before. Results allowed to infer new phylogenetic relationships, and propose taxonomic novelties to accommodate them, including up to ten new families and a new suborder. Giacomia (for which a new species from China is here described) forms a monophyletic clade with Melanoleuca (Melanoleucaceae) nested inside suborder Pluteineae, together with the families Pluteaceae, Amanitaceae (including Leucocortinarius), Limnoperdaceae and Volvariellaceae. The recently described family Asproinocybaceae is shown to be a later synonym of Lyophyllaceae (which includes also Omphaliaster and Trichocybe) within suborder Tricholomatineae. The families Biannulariaceae, Callistosporiaceae, Clitocybaceae, Fayodiaceae, Macrocystidiaceae (which includes Pseudoclitopilus), Entolomataceae, Pseudoclitocybaceae (which includes Aspropaxillus), Omphalinaceae (Infundibulicybe and Omphalina) and the new families Paralepistaceae and Pseudoomphalinaceae belong also to Tricholomatineae. The delimitation of the suborder Pleurotineae (= Schizophyllineae) is discussed and revised, accepting five distinct families within it, viz. Pleurotaceae, Cyphellopsidaceae, Fistulinaceae, Resupinataceae and Schizophyllaceae. The recently proposed suborder Phyllotopsidineae (= Sarcomyxineae) is found to encompass the families Aphroditeolaceae, Pterulaceae, Phyllotopsidaceae, Radulomycetaceae, Sarcomyxaceae (which includes Tectella), and Stephanosporaceae, all of them unrelated to Pleurotaceae (suborder Pleurotineae) or Typhulaceae (suborder Typhulineae). The new family Xeromphalinaceae, encompassing the genera Xeromphalina and Heimiomyces, is proposed within Marasmiineae. The suborder Hygrophorineae is here reorganized into the families Hygrophoraceae, Cantharellulaceae, Cuphophyllaceae, Hygrocybaceae and Lichenomphaliaceae, to homogenize the taxonomic rank of the main clades inside all suborders of Agaricales. Finally, the genus Hygrophorocybe is shown to represent a distinct clade inside Cuphophyllaceae, and the new combination H. carolinensis is proposed.
... accessed on 1 May 2023) to retrieve similar sequences. Other sequences of cyphelloid basidiomycetes, including those generated by Bodensteiner et al. [45], Laessøe et al. [54], Baltazar et al. [48], Karasiński et al. [56], and Vizzini et al. [70], were downloaded and included in the dataset. Existing sequences of known bioluminescent fungi were also downloaded from GenBank to compose a final dataset that includes all known bioluminescent and cyphelloid lineages. ...
... Regarding the cyphelloid genera within Agaricomycetes, our LSU rDNA analyses retrieved 11 lineages of cyphelloid fungi and the phylogenetic relationship of the cyphelloid genera agrees with recent phylogenetic studies [45,50,56]. However, we highlight that sequences of the collection PB327 named as Calathella columbiana appear in different positions and for this reason were excluded from the combined analyses: in the ITS rDNA tree within Cyphellopsidaceae (Figure 2), and in the LSU rDNA tree (Figure 1c) in a clade close to representatives of Entolomataceae. ...
During nocturnal field expeditions in the Brazilian Atlantic Rainforest, an unexpected bioluminescent fungus with reduced form was found. Based on morphological data, the taxon was first identified as belonging to the cyphelloid genus Maireina, but in our phylogenetic analyses, Maireina was recovered and confirmed as a paraphyletic group related to genera Merismodes and Cyphellopsis. Maireina filipendula, Ma. monacha, and Ma. subsphaerospora are herein transferred to Merismodes. Based upon morphological and molecular characters, the bioluminescent cyphelloid taxon is described as the new genus Eoscyphella, characterized by a vasiform to urceolate basidiomata, subglobose to broadly ellipsoid basidiospores, being pigmented, weakly to densely encrusted external hyphae, regularly bi-spored basidia, unclamped hyphae, and an absence of both conspicuous long external hairs and hymenial cystidia. Phylogenetic analyses based on ITS rDNA and LSU rDNA support the proposal of the new genus and confirm its position in Cyphellopsidaceae. Eoscyphella luciurceolata represents a new lineage of bioluminescent basidiomycetes with reduced forms.
