Three New Anamorph of <i>Ceramothyrium</i> from Fallen Leaves in Vietnam

Abstract

Three new anamorph of Ceramothyrium aquaticum sp. nov., Ceramothyrium exiguum sp. nov., and Ceramothyrium phuquocense sp. nov. are described and illustrated. These fungi were isolated from submerged decaying leaves collected from Phu Quoc National Park, Phu Quoc province, Viet Nam. The phylogeny based on ITS region and D1/D2 of the 28S rDNA gene showed that these fungi nested in the Ceramothyrium. Morphologically, C. aquaticum, C. phuquocense sp. nov. and C. exiguum sp. nov. are characterized; they were different from known anamorph species of Ceramothyrium by having one main axis and two lateral arms with 70 -90, 33.5 -72.5 and 70 -130 µm long main axis, respectively. The table to compare Ceramothyrium anamorph is also given.

Additions to Chaetothyriaceae (Chaetothyriales): Longihyalospora gen. nov. and Ceramothyrium longivolcaniforme, a new host record from decaying leaves of Ficus ampelas

“…& H. Maia as the type species, which has been collected from Brazil. Ceramothyrium species are characterized by a mycelial pellicle that covers the ascomata with a circumferential space around the maturing ascomata, lack of setae and hyaline, transversely pluriseptate ascospores (Batista and Maia 1956; Chomnunti et al 2012; Tsurumi et al 2018). Most Ceramothyrium species have been collected from terrestrial habitats and their asexual morph has been recorded as Stanhughesia Constant.…”

“…Most Ceramothyrium species have been collected from terrestrial habitats and their asexual morph has been recorded as Stanhughesia Constant. (Chomnunti et al 2012; Réblová et al 2013; Wijayawardene et al 2017; Tsurumi et al 2018). Ceramothyrium species seem to have a diverse distribution since they have been recorded from both temperate and tropical countries (i.e.…”

“…Ceramothyrium species seem to have a diverse distribution since they have been recorded from both temperate and tropical countries (i.e. Brazil, Canada, Georgia, Indonesia, Thailand, Panama, Philippines, South Africa, Sweden, Vietnam) (Hofmann and Piepenbring 2006; Chomnunti et al 2012; Crous et al 2012; Zeng et al 2016; Tsurumi et al 2018; Farr and Rossman 2019). Host-specificity of the taxa in this group has not yet been proven, since they have been recorded from various plant families (i.e.…”

“…Ceramothyrium longivolcaniforme , C. menglunense were introduced by Zeng et al (2016) and Hyde et al (2016) respectively. Yen et al (2018) introduced three Ceramothyrium species, viz. C. aquaticum , C. phuquocense and C. exiguum .…”

Geminoarcus maximus sp. nov. and Ceramothyrium brevis sp. nov., two novel aquatic hyphomycetes from Viet Nam

“…The second species belonged to Ceramothyrium, which was erected by Batista and Maia (1957) based on type species Ceramothyrium paiveae. The genus comprised of 43 species of which Stanhughesia and Trisulcosporium are anamorph of this genus (Constantinescu et al 1989;Crous et al 2012;Matsushima 1996;Yen et al 2018b). Ten anamorphs of Ceramothyrium were described: Stanhughesia carniolica-morph of C. carniolica, S. linnaeae-morph of C. linnaeae, S. lycopodii-morph of C. lycopodii, S. nipponica, morph of C. nipponica (Constantinescu et al 1989), Trisulcosporium morph of C. acerinum, Trisulcosporium morph of C. exiguum, Trisulcosporium morph of C. phuquocense (Yen et al 2018b), Ceramothyrium podocarpi morph and (Stanhughesia & Trisulcosporium morph) of Ceramothyrium melastoma morph (Crous et al 2012).…”
