“…Morphology and molecular data indicate that this new species is allied with M. longisetosus J.S. Oliveira & Capelari, describe recently from Brazil (Oliveira et al 2014). Marasmius longisetosus differs in forming a more deeply pigmented pileus (yellowish orange to pure orange), slightly longer basidiospores (mean 10.5 µm), and shorter, unbranched pileosetae.…”

Prior to this monographic treatment, limited research on the genus Marasmius (Basidiomycota, Agaricales) had been conducted in Madagascar. Based on field work in January 2013 and January–February 2014, which generated 45 specimens of Marasmius sensu stricto, supplemented by herbarium exsiccatae and published literature, 35 species of Marasmius are documented from Madagascar. Of these, 5 species are recognized herein as new to science, viz., Marasmius madagascariensis, M. rubrobrunneus, M. dendrosetosus, M. sokola and M. tanaensis; an additional 11 species represent new distribution records for Madagascar. Species delimitations are based on comprehensive morphological descriptions and molecular sequences (ITS) data. Line drawings of salient micromorphological features, color photographs of basidiomes, comparisons with allied taxa, a key to aid in identification, and phylogenetic inferences are provided.

“…Notes — Marasmius ambicellularis is a distinct species by not having morphological resemblance to any currently known species, except for M. linderioides ( Oliveira et al 2014 ). However, M. linderioides differs by having larger pileus (up to 8 mm diam); by more numerous lamellae (12–15) and 2–3 series of lamellulae; by shorter basidiospores (10–15 μm long); by the presence of well-developed pleurocystidia; and by having only Siccus -type broom cells in the pileipellis; with basidiomata generally found on substrate on the ground.…”

“…Mycelium tissues and lyophilised basidiome fragments were obtained according to Oliveira et al (2014) and were used for DNA extraction following various protocols ( Zolan & Pukkila 1986 , Dentinger et al 2010 , Justo et al 2011 ). PCR reagents were mixed as specified in Oliveira et al (2014) and Sánchez-Ramirez et al (2014) . Primers used were ITS1-F ( Gardes & Bruns 1993 ) and ITS4 ( White et al 1990 ) for the ITS rDNA and LR0R and LR5 ( Vilgalys & Hester 1990 ) for the LSU.…”

A morphological and phylogenetic evaluation of Marasmius sect. Globulares (Globulares-Sicci complex) with nine new taxa from the Neotropical Atlantic Forest

et al. 2020

View full text Add to dashboard Cite

The largest and most recently emended Marasmius sect. Globulares (Globulares-Sicci complex) has increased in number of species annually while its infrasectional organization remains inconclusive. During forays in remnants of the Atlantic Rainforest in Brazil, 24 taxa of Marasmius belonging to sect. Globulares were collected from which nine are herein proposed as new: Marasmius altoribeirensis, M. ambicellularis, M. hobbitii, M. luteoolivaceus, M. neotropicalis, M. pallidibrunneus, M. pseudoniveoaffinis, M. rhabarbarinoides and M. venatifolius. We took this opportunity to evaluate sect. Globulares sensu Antonín & Noordel. in particular, combining morphological examination and both single and multilocus phylogenetic analyses using LSU and ITS data, including Neotropical samples to a broader and more globally distributed sampling of over 200 strains. Three different approaches were developed in order to better use the genetic information via Bayesian and Maximum Likelihood analyses. The implementation of these approaches resulted in: i) the phylogenetic placement of the new and known taxa herein studied among the other taxa of a wide sampling of the section; ii) the reconstruction of improved phylogenetic trees presenting more strongly supported resolution especially from intermediate to deep nodes; iii) clearer evidence indicating that the series within sect. Sicci and sect. Globulares in the traditional concept are non-monophyletic by this more stringent evaluation; and iv) the existence of several monophyletic suprespecific groups equivalent to the stirpes of Singer – clusters of morphologically similar species. These two latter points corroborate with findings of previous studies implementing analyses with the entire genus. Based on these results, we proposed a new infrasectional classification elevating Singer's concept of stirpes to series. Thirteen new series, the emendation of three extant series and three subsections gathering these series based on the major clades are proposed.

“…Broom cells of some marasmioid mushrooms in Marasmiaceae -Marasmieae sensu Singer (1976) -are similar in shape to acanthophyses of Acanthocorticium (see Singer 1976Singer , 1986Kuo 2013;Oliveira et al 2014), and in some species they are also dextrinoid. A more detailed morphological comparison is desirable to properly compare these structures.…”

Molecular analyses have revealed a clade which equates with the genus name Mycetinis Earle. An overall survey of this genus, however, has not been forthcoming. The current study summarizes taxa which are placed in Mycetinis based on morphological and/or molecular data. Fifteen taxa are accepted: Mycetinis scorodonius f. diminutivus and Mycetinis yunnanensis are proposed as new, while Mycetinis cinnamomeus, Mycetinis olidus, Mycetinis prasiosmus, Mycetinis subalpinus and Myctinis virgultorum are newly recombined binomials. Phylogenies based on molecular data show overall disposition in Omphalotaceae, Gymnopus and allied genera, and taxa of Mycetinis.
