BASIDIOMYCETE YEASTS ISOLATED FROM PELTIGERA LICHENS OF SOUTHERN CHILE

This resource represents to date the largest collection of basidiomycetes yeasts isolated from lichen thalli and the first collection of yeasts associated with Peltigera lichens. The Microbial Ecology Lab (Universidad de Chile) collection comprises 180 basidiomycetes yeasts isolated and identified from Peltigera lichen thalli (P. frigida, P. fuscopraetextata, P. rufescens and Peltigera ponojensis/monticola 11) collected from southern Chile. The isolates were identified by sequencing the ITS marker and subsequent phylogenetic analyses. A great diversity of basidiomycetes genera was found, belonging to the classes Agaricostilbomycetes, Cystobasidiomycetes, Microbotryomycetes and Tremellomycetes and to the orders Agaricostilbales, Cystobasidiales, Cystofilobasidiales, Filobasidiales, Holtermanniales, Sporidiobolales and Tremellales. Georeferencing included for all specimens.

本资源截至目前代表了一组迄今为止最大的菌褶菌酵母集合，这些酵母是从地衣体中分离出来的，同时也是首次与 Peltigera 地衣相关的酵母集合。智利大学微生物生态实验室的收藏包括从智利南部采集的 Peltigera 地衣体（P. frigida、P. fuscopraetextata、P. rufescens 及 Peltigera ponojensis/monticola 11）中分离并鉴定出的 180 种菌褶菌酵母。这些分离株通过ITS标记的测序及后续的亲缘关系分析被鉴定。研究发现，菌褶菌属的多样性丰富，隶属于 Agaricostilbomycetes、Cystobasidiomycetes、Microbotryomycetes 和 Tremellomycetes 四个类群，以及 Agaricostilbales、Cystobasidiales、Cystofilobasidiales、Filobasidiales、Holtermanniales、Sporidiobolales 和 Tremellales 七个目。所有标本均进行了地理定位。
