Abstract
Three new species isolated from sugarcane rhizosphere in China, namely Conlariumbaiseensesp. nov., C.nanningensesp. nov., and C.saccharisp. nov., are described and illustrated. Molecular evidence (phylogenetic analysis of combined LSU, SSU, ITS and RPB2 sequence data) and phenotypical characters support their independent status from related and similar species. The new species, as dark spetate endophytes, inhabit sugarcane rhizosphere and can form a symbiosis with sugarcane.
Highlights
The genus Conlarium, described by Liu et al (2012), belongs to the Conlariaceae, a family of freshwater ascomycetes (Zhang et al 2017)
C. baiseense and C. sacchari formed a separate clade with 1.00 support of Bayesian tree with posterior probability (BPP) and 100% support of NJ, C. nanningense formed a clade with C. duplumascospora with 0.96 support of BPP, and three of the new species were clearly separated from other Conlarium species
The ascomata of C. aquaticum, C. thailandense, C. sacchari, C. baiseense, and C. nanningense was not observed on the medium
Summary
The genus Conlarium, described by Liu et al (2012), belongs to the Conlariaceae, a family of freshwater ascomycetes (Zhang et al 2017). This genus includes three species: C. duplumascospora, C. aquaticum, and C. thailandense. During our ongoing survey of dark septate endophytes which inhabit sugarcane rhizosphere in Guangxi province, China, three undescribed. The specimens were deposited in the Mycological Herbarium, Institute of Microbiology, Chinese Academy of Sciences, Beijing, China (HMAS)
