The genusRhopalostroma(Xylariaceae) in Thailand

A multiple gene genealogy reveals phylogenetic placement of Rhopalostroma lekae

“…The inconspicuous, minute and fragile nature of the stromata might be a possible reason for the lack of collections reported. The collection from northern Thailand is identical to the sexual morph in the protologue of R. lekae (Whalley et al 1998). Dull sulfur yellow-orange granules were observed beneath the surface of the head part of the stroma by Whalley et al (1998) and also in this study.…”

“…Recent collections of Rhopalostroma species support the fact that it is exclusively distributed in Asia and Africa (Whalley et al 1998, Stadler et al 2010a, Patil et al 2012. The inconspicuous, minute and fragile nature of the stromata might be a possible reason for the lack of collections reported.…”

“…Type species:-(as listed in protologue), Thailand, Nakon Ratchasima Province, Khao Yai National park, Orchid Falls Trail, in dead wood, 30 November 1996, T. Flegel, (holotype, RFD, no accession number) (Whalley et al 1998)-stated herbarium contacted and did not have type material (see discussion). Etymology:-named in honor of the distinguished Thai Mycologist, Leka Manoch.…”

“…In combined gene phylogentic analysis, Anthostomella and Biscogniauxia formed a basal clade to all other xylarioid genera. Habitat and distribution:-Saprobic on dead bark (Whalley et al 1998), bark of Memecylon umbellatum Burm. (Patil et al 2012), Thailand (Northern Thailand) and India (Patil et al 2012).…”

“…Rhopalostroma was introduced by Hawksworth (1977) (Hawksworth 1979, Hawksworth & Whalley 1985, Vaidya et al 1991, Whalley and Thienhirun 1996, Whalley et al 1998, Patil et al 2012. Rhopalostroma lekae has also been reported from India (Patil et al 2012).…”
