Stachybotrys-like taxa from karst areas and a checklist of stachybotrys-like species from Thailand

Abstract

During a survey of hyphomycetes from karst areas in Thailand, four stachybotrys-like taxa, viz., Cymostachys garethjonesii sp. nov., Memnoniella oblongispora sp. nov., M. nilagirica comb. nov. and Stachybotrys microspora were identified and are provided with descriptions in this paper. The new species are introduced based on morphological and molecular differences and compared with similar or related taxa. Memnoniella nilagirica and Stachybotrys microspora are new records for Thailand. An annotated checklist of stachybotrys-like taxa in Thailand is provided based on previous publications and database searches.

Stachybotrys musae sp. nov., S. microsporus, and Memnoniella levispora (Stachybotryaceae, Hypocreales) Found on Bananas in China and Thailand

“…However, Lombard et al [ 20 ] resurrected Memnoniella as a distinct genus in Stachybotryaceae . Lin et al [ 22 ], Doilom et al [ 23 ], Hyde et al [ 17 ], and Mapook et al [ 24 ] further supported the observations of Lombard et al [ 20 ] and treated Memnoniella and Stachybotrys as two distinct genera. Hyde et al [ 17 ] documented nine species of Memnoniella with DNA sequence data.…”

“…Stachybotrys is common in soil, plant litter (hay, straw, cereal grains, and decaying plant debris), marine habitats, and air [ 19 , 20 , 23 , 24 , 26 ]. In addition, Stachybotrys has been detected on damp paper, cotton, linen, cellulose-based building materials (drywalls, wallpapers in indoor environments), water-damaged indoor buildings, and air ducts [ 5 , 17 , 19 , 28 , 31 , 32 , 33 , 34 , 35 ].…”

“…Many species of Memnoniella and Stachybotrys have been documented from China and Thailand. Lin et al [ 23 ] provided a check list of Stachybotrys species recorded from different hosts and substrates in Thailand ( S. albipes, S. bambusicola, S. chartarum, S. elegans , S. microsporus, S. nephrosporus, S. palmae, S. parvisporus, S. renisporus, S. ruwenzoriensis, S. sansevieriae, S. suthepensis , and S. theobromae ). Stachybotrys aksuensis (Xinjiang), S. biformis (Shaanxi), S. littoralis (Guangdong), and S. yushuensis (Qinghai) were introduced from soil habitats in China [ 49 ].…”

Discovery of Cymopolyphenols A–F From a Marine Mesophotic Zone Aaptos Sponge-Associated Fungus Cymostachys sp. NBUF082

“…Upon close examination of the literature, it was determined that the morphology of strain NBUF082 matched what was described for the genus Cymostachys when it was established in recent reports, and it was also conclusively identified as a Cymostachys sp. by the ITS region sequence of this organism ( Lin et al, 2016 ; Lombard et al, 2016 ). Although Cymostachys is closely related to the genus Stachybotrys , only the latter has been extensively studied for its natural product chemistry ( Wang et al, 2015 ; Zhao et al, 2017 ; Jagels et al, 2019 ; Zheng et al, 2019 ).…”

“…The reverse side of the medium was fawn-colored and non-extravasated. The strain was able to be identified as belonging to the genus Cymostachys according to its morphological traits ( Lin et al, 2016 ), and sequence analysis of the ITS region (GenBank accession no. MW077215) as described previously ( Henríquez et al, 2014 ; Lombard et al, 2016 ).…”
