On new lichens from the Himalayas-I

Abstract

The paper deals with 7 new species and one new variety of lichens from the Himalayan region. They are Cetraria pallida Awasthi, C. nepalensis Awasthi, Physcia melanotricha Awasthi, Ph. askotensis Awasthi, Anaptychia himalayensis Awasthi, A. pellucida Awasthi, Peccania Hoegii Awasthi, and Physcia endococcina var.latiloba H. Magn. Mention may be made of the two interesting features, notably deep blue colouration in the cortical region of Anaptychia himalayensis and A. pellucida by the interaction of iodine solution and the strange dark nubilations in the thecium of Peccania Hoegii.
