Cantharellaceae of Guyana II: New species ofCraterellus, new South American distribution records forCantharellus guyanensisandCraterellus excelsus, and a key to the Neotropical taxa

Abstract

Craterellus olivaceoluteus sp. nov. and Craterellus cinereofimbriatus sp. nov. are described as new to science. These fungi were collected from Guyana in association with ectomycorrhizal host trees in the genera Dicymbe (Fabaceae subfam. Caesalpinioideae) and Pakaraimaea (Dipterocarpaceae). Cantharellus guyanensis Mont., originally described from French Guiana, is redescribed from recent collections from Guyana, with additional range extensions for the species provided based on material examined from French Guiana, Venezuela, and north central, northeastern and southern Brazil, circumscribing nearly the entire Guiana Shield region and beyond. A new distribution record from French Guiana is provided for Craterellus excelsus T.W. Henkel & Aime. Macromorphological, micromorphological and habitat data are provided for the new species and C. guyanensis as well as DNA sequence data from the nuclear ribosomal regions of the internal transcribed spacer (ITS) and 28S large subunit (LSU); additional sequence data is provided for C. guyanensis and C. excelsus specimens collected outside Guyana. The relationships of these taxa within the Cantharellaceae were evaluated with phylogenetic analyses of ITS and LSU sequence data. This work brings the total number of Cantharellaceae species known from Guyana to eight. A key to the Cantharellus and Craterellus species known from the lowland Neotropics and extralimital montane Central and South America is provided.

Diversity and Distribution of Ectomycorrhizal Fungi from Amazonian Lowland White‐sand Forests in Brazil and French Guiana

“…Cantharellus guyanensis, which is widely distributed across Brazil to Venezuela and Colombia (Henkel et al . ), is particularly noteworthy in that it is a fragrant, delectable species.…”

“…Whenever possible, we identified fungi to species based on morphology and published descriptions ( e.g., Pegler & Fiard , Singer , Henkel et al . , , Sá et al . 2013b).…”

“…These species can be found in very diverse habitats, even on terra firme (Singer & Ara ujo 1979, this study). Cantharellus guyanensis, which is widely distributed across Brazil to Venezuela and Colombia (Henkel et al 2014), is particularly noteworthy in that it is a fragrant, delectable species.…”

Cantharellus cyphelloides (Cantharellales), a new and unusual species from a Japanese evergreen broad-leaved forest

“…These studies provided the basis for existing knowledge of cantharelloid fungi. Subsequent morphological studies (Petersen and Mueller 1992;Feibelman et al 1996;Redhead et al 1997;Buyck et al 2000;Eyssartier et al 2002Eyssartier et al , 2003 and molecular phylogenetic analyses (Feibelman et al 1997;Pine et al 1999;Dahlman et al 2000;Moncalvo et al 2006;Tibuhwa et al 2012;Henkel et al 2014;Shao et al 2014) provide additional detailed information on the circumscription of Cantharellus. Recently, Buyck et al (2014) reported on the phylogenetic relationships within Cantharellus based on DNA sequence data for Cantharellus species from around the world, and discussed the taxonomy of the genus at the section and subgenus levels.…”

Tree communities and soil properties influence fungal community assembly in neotropical forests

“…Indeed, in South America, the interest in mycology has only begun in the 19th century (Montagne, ). In between, mycologists have gathered specimens throughout Amazonia (e.g., Henkel et al, ; Matheny, Aime, & Henkel, ; Sánchez‐García, Henkel, Aime, Smith, & Matheny, ; Singer & Aguiar, ; Trierveiler‐Pereira & Baseia, ; Vasco‐Palacios, Hernandez, Peñuela‐Mora, Franco‐Molano, & Boekhout, ). Nevertheless, the known distribution of neotropical fungi remains patchy and biased toward accessible sites (Roy et al, ; Sulzbacher, Grebenc, Giachini, Baseia, & Nouhra, ) and little is known on their ecology or their habitat.…”
