Lichen Herbarium (H): Lichenes externi

Lichenes externi is part of the lichen collections of the Finnish Museum of Natural History. This collection contains lichen specimens worldwide (except for Finland and Russian Fennoscandia) and is especially strong in specimens from boreal and temperate Europe, Asia and North America. Taxonomically the families Cladoniaceae, Parmeliaceae and Peltigeraceae are well represented. Type specimens are being digitized and transferred into a separate Lichen type collection.

Lichenes externi是芬兰自然历史博物馆地衣藏品的一部分。该藏品包含全球范围内（芬兰及俄罗斯芬诺斯坎迪亚地区除外）的地衣标本，尤其以来自寒带及温带欧洲、亚洲和北美洲的标本为优势。在分类学层面，石蕊科（Cladoniaceae）、梅衣科（Parmeliaceae）和肺衣科（Peltigeraceae）的代表性尤为充分。模式标本正在进行数字化处理，并将转移至独立的地衣模式标本收藏中。
