... The increasing number of molecular taxonomic studies revealed that many Agaricales species in the Republic of Korea have been misidentified and were in fact new or unrecorded species [22,23,[38][39][40]. In line with the previous sequence-based taxonomic studies, this study also discovered many unrecorded Agaricales species belonging to diverse genera such as Calocybe, Cortinarius, Hygrocybe, Inocybe, Lepista, Leucoagaricus, and Marasmius. ...
Agaricales species form pileate-stipitate fruiting bodies and play important roles in maintaining the terrestrial ecosystem as decomposers, symbionts, and pathogens. Approximately 23,000 Agaricales species have been known worldwide, and 937 species have been recorded in the Republic of Korea. However, most of them were identified solely based on morphological characteristics that often led to misidentifications. The specimens collected from 2018 to 2020 in the Republic of Korea were identified based on phylogenetic analysis of the internal transcribed spacer (ITS) sequences. Their identities were confirmed by microscopic characteristics. As a result, 14 Agaricales species were discovered for the first time in the Republic of Korea. They belonged to nine genera: Agaricus, Calocybe, Cortinarius, Hygrocybe, Inocybe, Lepista, Leucoagaricus, Marasmius, and Psathyrella. Detailed macroscopic and microscopic descriptions were provided to help distinguish these species. The morphological and molecular data provided in this study will serve as reliable references for the identification of Agaricales species.

However, M. albopurpureus has a glabrous stipe pale violet in upper part, clavate cheilocystidia, and grows in forest (Wang et al. 2015); M. purpureostriatus differs in having a conical pileus, a purplish gray to reddish brown stipe with glabrous surface, and grows in forest (Hongo 1958;Wannathes et al. 2009a;Antonín et al. 2010); M. odoratus has a long stipe (10.7e16.5 Â 0.3e0.35 cm) with glabrous surface, a fragrant odor, narrower basidiospores measuring 17e23 Â 4e5 mm, and grows in forest (Farook and Manimohan 2015); M. indopurpureostriatus has a larger basidiomata (1.6e11 cm), clavate to pyriform cheilocystidia, narrower basidiospores measuring 21.5e23.3 ...
Marasmius campestris (Marasmiaceae, Agaricales), a member of sect. Globulares, is described as a new species from Hainan Island, a tropical region of China. It is morphologically characterized by an umbilicate, deeply sulcate and striped, purple-tinged pileus, a stipe covered with tiny scales, large basidiospores, well-developed cheilocystidia with irregular shape, a pileipellis consisting of Globulares-type cells, and growth in grassland. The phylogenetic analyses of DNA sequences from nuc rDNA internal transcribed spacer (ITS) also confirm that it forms an independent lineage within Marasmius. Consequently, a description, color photos of fresh basidiomata and line-drawings of microstructures are presented.
... Identified sequences assigned to members of sect. Marasmius passing quality and identity control (alignments and preliminary analyses) were preferably included, principally those published in related studies (Wannathes et al. 2009, Antonín et al. 2014. Three datasets were established in order to refine the phylogenetic hypothesis of the study. ...
Two taxa of Marasmius sect. Marasmius are herein (re)described, reported from the Amazon forest. Marasmius calvocystidiatus is proposed as a new species on account of its glabrous (bald) pileus with smooth cystidia, some of them lobed or with coarse excrescences in the pileipellis. On the other hand, the only taxon of sect. Marasmius subsect. Horriduli, Marasmius horridulus is redescribed herein, highlighting its “hairy” pileus (similar to Crinipellis species) with abundant, dextrinoid, setiform hairs rising from a hymeniform to subhymeniform pileipellis composed of anomalous broom-cells. Molecular evidence (based on ITS data) indicates that both taxa indeed belong to Marasmius sensu stricto, and are immediate sister to each other in trees reconstructed by phylogenetic analyses accomplished in this study. Our phylogenetic hypothesis also suggests that M. calvocystidiatus and M. horridulus are close to M. purpureisetosus, a species with sparse setiform hairs and also anomalous thick-walled broom cells in the pileipellis, and to a group of species members of sect. Marasmius subsect. Rotalis. In this paper we present morphological descriptions, line drawings, color plates and a phylogenetic hypothesis in support of our findings for M. calvocystidiatus and M. horridulus.
... The edited sequence was then used for BLAST searches in the GenBank database to determine the most closely related taxa for molecular identification. A dataset was generated from the highest scored hits most relevant for identification, as well as from samples previously used in the phylogenetic reconstruction of Marasmius (Wannathes et al. 2009b, Antonín et al. 2010). GenBank accession numbers for all of the acquired sequences has been indicated in Fig. 1. ...
A marasmioid fungus: Marasmius indopurpureostriatus (Marasmiaceae, Basidiomycota) is proposed here as new to science from Sikkim, a small Himalayan state in India. A comprehensive description with illustrations to aid in the identification, comparisons with morphologically similar taxa and an artificial key to the species of Marasmius sect. Globulares, previously reported from India are provided.

Marasmius bekolacongoli Beeli (Beeli 1928;Antonín et al. 2010), a widespread species in tropical Africa, has a much larger [(10)36-67(100) mm diam.] pileus and longer stipe [50-150×2.5-6(10) ...
... Marasmius laticlavatus Wannathes et al. (Wannathes et al. 2009b), originally reported from Thailand, differs from M. albopurpureus in its plicate pileus with a brown disc and pallid grayish cream margin, cream well-developed lamellae, and larger basidiospores (mean 30.4×5.6 μm). Marasmius purpureostriatus Hongo (Hongo 1958;Antonín et al. 2010), firstly discovered from Japan, differs from the new species in forming a conical pileus, darker violet and full-developed lamellae, and wider spores (21-25×5-6.5 μm). Marasmius sparsifolius Chun Y. Deng & T.H. Li (Deng et al. 2012), another species described from China with distant lamellae, differs from the new species in possessing an orangish-white to orange pileus, Siccus-type pleurocystidia with broom cells, and different spore shape (7.5-10×3-4 μm). ...
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.
