Deniquelata vittalii sp. nov., a novel Indian saprobic marine fungus on Suaeda monoica and two new records of marine fungi from Muthupet mangroves, East coast of India

Deniquelata quercina sp. nov.; a new endophyte species from Persian oak in Iran

“…Asci and pedicels of D. quercina (85-155 × 13-18 μm, 17-48 μm) are larger than those of D. vittalii (75-135 × 10-19 μm, 7-15 μm) and D. barringtoniae (68−80 × 10−15 μm, 9−17 μm) (Table 2). Moreover, ascospores of D. barringtoniae (14−16 × 5−7 μm) are shorter than that of D. quercina (18−21 × 9−11 μm) and D. vittalii (17.5-25 × 7.5-13.5 μm) , 2014b, Devadatha et al 2018. Furthermore, D. vittalii is distinct in terms of its ellipsoidal to broadly oblong brown ascospores with 3-6 transverse septa and deeply constricted in the middle septum (Devadatha et al 2018) whereas D. quercina has oblong, ellipsoid, ovoid to fusoid ascospores with widest second cell, 3 transverse septa and constricted at all septa.…”

“…Deniquelata quercina is distinguished from D. barringtoniae and D. vittalii regarding differences in type of substrate-dependent. Deniquelata barringtoniae is a pathogenic species causing necrosis on living leaves while D. vittalii is a saprobic fungus on decaying woody (Ariyawansa et al 2013, Devadatha et al 2018, while D. quercina is associated with branches of Persian oak trees as an endophyte species.…”

“…Additionally, D. barringtoniae and D. quercina have been isolated from substrates in terrestrial circumstances, while D. vittalii has been related to marine environments, suggesting the diverse ecological and unlimited geographical distribution of the genus around the world (Devadatha et al 2018).…”

“…Alignment and phylogenetic analysis New sequences generated in this study were edited using the BioEdit version 7.0.5.3 (Hall 1999). Reference sequences were obtained from the GenBank based on the BLAST search similarity resulted from 18S, 28S and ITS regions and according to the review of published literature (Ariyawansa et al 2013, 2014a, b, Devadatha et al 2018. All sequences used in this study are listed in Table 1.…”

“…Ascospores are oblong to narrowly oblong, reddish brown to dark yellowish brown, muriform with three transverse septa and 1-2 vertical septa, verruculose and lacking a sheath (Ariyawansa et al 2013). This genus currently includes two species, D. barringtoniae and D. vittalii Devadatha, V.V Sarma, E.B.G Jones (Ariyawansa et al 2013, Devadatha et al 2018. Deniquelata barringtoniae is a pathogenic species causing necrosis on living leaves of Barringtonia asiatica (Ariyawansa et al 2013) and D. vittalii has been recorded on decaying woody stem of the Suaeda monoica (Devadatha et al 2018).…”
