tailieunhanh - Three new species of basidiomycetous fungi from India

In this paper, 2 lepiotaceous mushrooms [Lepiota indica sp. nov. and Lepiota attenuispora sp. nov. (Agaricaeae)] and 1 Limacella magna sp. nov. in the Amanitaceae are described. Lepiota indica has scurfy brownish carpophores, minute spores, and chains of golden brown-walled pileal elements. | Turkish Journal of Botany Research Article Turk J Bot (2013) 37: 1188-1194 © TÜBİTAK doi: Three new species of basidiomycetous fungi from India 1, 1 2 Babita KUMARI *, Narender Singh ATRI , Ramesh Chandra UPADHYAY 1 Department of Botany, Punjabi University, Patiala, India 2 Directorate of Mushroom Research, Chambaghat, Solan, India Received: Accepted: Published Online: Printed: Abstract: In this paper, 2 lepiotaceous mushrooms [Lepiota indica sp. nov. and Lepiota attenuispora sp. nov. (Agaricaeae)] and 1 Limacella magna sp. nov. in the Amanitaceae are described. Lepiota indica has scurfy brownish carpophores, minute spores, and chains of golden brown-walled pileal elements. Lepiota attenuispora has a shaggy appearance, an appendiculate veil of the pileus margin, and a stipe sheathed with soft cottony scales. Limacella magna is a species characterized by prominent brown scales on the pileus and stipe, presence of a glutinous layer, and a trichodermal pileus cutis. Key words: Basidiomycetes, taxonomy, macrofungi, India 1. Introduction The Indian subcontinent is rich in natural resources and vegetation, which support the luxuriant growth of different types of naturally occurring fungi. Among these are lepiotoid mushrooms in the family Agaricaceae with a fibrillose or floccose fibrillose surface; white or lightcolored free lamellae; a single, simple annulus; largely white, pink, or pale spore deposit; and sterile lamella edges. During the studies on diversity of agaricoid mushrooms in North India, 2 new species, Lepiota indica and Lepiota attenuispora belonging to family Agaricaeae, were encountered, while 1 new species, Limacella magna, belonging to genus Limacella, an agaricoid member of family Amanitaceae, was found growing in old dung in a Pinus forest in Solan in Himachal Pradesh. This latter new species is characterized by medium-sized carpophores .
