Corneriella was introduced as a new genus by Sánchez-García et al. (2014) and as its sister to Porpoloma and Dennisiomyces in Tricholomataceae (Agaricales, Basidiomycota). Currently, this genus comprises of three tropical species. Corneriella bambusarum (type species) was previously identified as Porpoloma bambusarum and described in Hawaii, based on the presence of cheilocystidia and regular rather than tridirectional lamellar trama (Sánchez-García et al. 2014), Cantharellula humicola is transferred to the new genus Corneriella (Corneriella humicola), it is introduced from Malaysia; and there are two undescribed species from Puerto Rico and Brazil (Sánchez-García et al. 2014); the latest one Corneriella indica was identified from Kerala (India) (Raj et al. 2015). Corneriella is characterized by putatively saprotrophic species occurring on soil and humus, tricholomatoid basidiomata that do not change color when cut or bruised and adnexed to sinuate or decurrent, and sometimes forked lamellae that are initially pale and become darker. Additionally, the genus has smooth, thin-walled, and amyloid basidiospores; conspicuous, versiform, thin-walled cheilocystidia; a hymenium devoid of pleurocystidia; a cutis-type pileipellis with suberect to erect terminal cells; and hyphae with clamp connections (Sánchez-García et al. 2014).
