Another species complex in myxomycetes: diversity of peridial structures in Lycogala epidendrum

Past and Ongoing Field-Based Studies of Myxomycetes

“…The morphospecies, which is one of the most familiar of all myxomycetes, now appear to consist of numerous biological species. The same situation has been demonstrated for other morphospecies [ 111 , 112 , 113 , 114 , 115 , 116 ].…”

“…In brief, being able to obtain and analyze genetic sequences from myxomycetes (mostly from fruiting bodies) provides exciting new insights into what constitutes a “biological species” as opposed to a morphological species (or morphospecies). The system of classification traditionally used for myxomycetes is currently undergoing changes that have already resulted in a realignment of taxa, even at the level of family and order [ 111 , 112 , 113 , 114 ]. Some of the variable species, when subjected to study using the new data that are now available, have turned out to be complexes of several to even numerous biological species.…”

Dataset of barcoded Reticulariaceae: ten years of DNA sequencing

“… Reticulariaceae is a well-known family of myxomycetes , the first representatives of which were described in the 17 th -18 th centuries ( Leontyev et al 2022b , Leonytev and Schnittler 2022 ). In 2012, the family contained three genera and 25 accepted species ( Lado 2005 ), including the trivial Lycogala epidendrum (L.) Fr.…”

“…These studies increased the number of species of the Reticulariaceae to 52 ( Lado 2005 ), the number of genera to six and one more genus, Licaethalium , was re-erected within the Cribrariaceae for species, previously classified within Reticulariaceae ( Leontyev et al 2019b ). Fifteen species of the genus Lycogala , nine species and one subspecies of the genus Tubifera , three species of the genus Alwisia and two species of the genus Siphoptychium were described ( Leontyev et al 2014a , Leontyev et al 2014b ,Leontyev et al 2015, Leontyev et al 2019a, Lloyd et al 2019 , Leontyev et al 2022a , Leontyev et al 2022b , Leontyev and Schnittler 2023b , Leontyev et al 2023 ). The classical species L. epidendrum and T. ferruginosa have proven to represent species complexes, which contain at least 13 and 76 biological species, respectively ( Leontyev and Schnittler 2023a ).…”

Atividade Antimicrobiana De Extratos De Etálios De Lycogala Epidendrum (Liceales, Myxomycetes) Em Diferentes Fases De Amadurecimento

“…(Liceales, Reticulariaceae) abrange sete espécies de mixomicetos, caracterizadas pelos etálios subglobosos, cônicos ou subcilíndricos, (0,5)2-7(70) mm de diâmetro, contendo um pseudocapilício constituído por túbulos conectados com a face interna do córtex, quase lisos a enrugados, ornamentados com espinhos, verrugas ou papilas, e esporo hialino a castanho-acinzentado claro sob luz transmitida, (4)5-7(8) µm de diâmetro (FARR, 1976;ONSBERG, 1972). Todas as espécies do gênero apresentam vesículas na camada mais externa do córtex, distribuídas em diferentes arranjos, contendo gotículas de óleo, grânulos, pigmentos e cristais de compostos com cálcio (LEONTYEV et al, 2022). Na fase madura, o córtex do etálio apresenta coloração em tons de castanho a castanho-escuro em L. conicum Pers.…”
