“…As for M. suthepensis , other cases in Marasmius presenting supposedly wide distribution (showing molecular conspecificity) may suggest that the mycota of the Neotropics and Tropical Asia, which was connected in the remote past, still looks genetically linked. Many studies in Indo-Malaysian, Australasian, Oceanian and Afrotropical areas have already recorded species originally described in the Neotropics ( Singer 1976 , Corner 1996 , Desjardin & Horak 1997 , Desjardin et al 2000 , Antonín 2007 , Tan et al 2009 , Wannathes et al 2009 , Antonín et al 2012 , Deng et al 2012 ), but molecular comparison between strains indicating same morphological species is still in the beginning. We cannot discard the possibility that ITS is limited to solve species complex in allopatry, indicating that the samples represent very recently diverged taxa with little variation in particularly this marker.…”
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.

Marasmius albopurpureus, a new species belonging to section Globulares, was found on a subtropical island, Baili Island, in southern China. It is characterized by its white to purple rugulose to sulcate pileus, distant and sometimes underdeveloped lamellae, and long basidiospores. It is described, illustrated and compared with similar taxa according to the morphological and molecular data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
