Antarktika’dan Lambiella psehota’nın asit yoksunu popülasyonu, cinste Campbell Adası’ndan yeni bir kombinasyon ve tür tayin anahtarı

Antarktika’da likenleşmiş mantar cinslerinden biri olan Lambiella’nın L. impavida ve L. psephota olmak üzere iki adet türü bilinmektedir. Burada, Kuzey-Doğu Antarktika Yarımadası bölgesindeki James Ross Adası’ndan toplanan yeni bir L. psephota kemotipini rapor ediyoruz. Yeni kemotip filogenetik olarak L. psephota'ya aittir. Norstitik asit içermeyen L. psephota'nın nrITS, mtSSU ve RPB1 gen bölgeleri çalışılmıştır. Ayrıca bu yayınla birlikte Rimularia maculata'yı Lambiella cinsinea aktarıyoruz ve dünya çapında bilinen 17 Lambiella türü için bir tayin anahtarı veriyoruz.

An acid deficient population of Lambiella psephota from Antarctica and a new combination in the genus from Campbell Island with a world-wide key to the genus

Only two species of the lichen genus Lambiella are known from Antarctica: L. impavida and L. psephota. Here we report a new chemotype of L. psephota collected from James Ross Island in the North-East Antarctic Peninsula region. nrITS, mtSSU and RPB1 gene regions of the norstictic acid deficient L. psephota were obtained, which showed the new chemotype phylogenetically belongs to L. psephota. We also transfer Rimularia maculata to Lambiella, and provide an identification key of the 17 known species of Lambiella world-wide

Keywords:
