tailieunhanh - A new species of Cyathus (Agaricaceae) from India

The Acharya Jagadish Chandra Bose Indian Botanic Garden is a well-known botanical garden. Cyathus thindii, a new species of bird’s nest fungus, was collected from this garden, and is described and illustrated in the present paper. It is distinct with its sessile basidiomata growing on a white mycelial pad, plicate exterior (partly) and interior wall of the peridium, comparatively large peridioles without tunica, and medium sized spores. | Turkish Journal of Botany Turk J Bot (2016) 40: 97-103 © TÜBİTAK doi: Research Article A new species of Cyathus (Agaricaceae) from India 1, 2 1 3 Kanad DAS *, Manoj Emanuel HEMBROM , Arvind PARIHAR , Rui Lin ZHAO 1 Botanical Survey of India, Cryptogamic Unit, Howrah, India 2 Botanical Survey of India, Central National Herbarium, Howrah, India 3 The State Key Lab of Mycology, Institute of Microbiology, Chinese Academy of Sciences, Beijing, PR China Received: Accepted/Published Online: Final Version: Abstract: The Acharya Jagadish Chandra Bose Indian Botanic Garden is a well-known botanical garden. Cyathus thindii, a new species of bird’s nest fungus, was collected from this garden, and is described and illustrated in the present paper. It is distinct with its sessile basidiomata growing on a white mycelial pad, plicate exterior (partly) and interior wall of the peridium, comparatively large peridioles without tunica, and medium sized spores. Its relation with allied taxa is discussed and a provisional key to the Indian species of Cyathus is given in the present paper. Key words: Bird’s nest fungi, Agaricaceae, taxonomy, new species, India 1. Introduction The genus Cyathus Haller (Agaricaceae) can be characterized as follows: peridium vase-like or infundibuliform to inverted bell-shaped with 3 layers, surface plicate or smooth, often covered with shaggy or tomentose hairs on the outside; peridiole (gleba) lens-shaped and attached to the peridium with a thread-like cord (funiculus); basidiospore hyaline, smooth and mostly with a thick wall, while the shape and size vary (Lloyd, 1906; Brodie, 1975; Miller and Miller, 1988). Two other allied genera are Nidula . White and Crucibulum Tul. & C. Tul. Nidula differs from Cyathus by its lack of a funicular cord with the peridiole. Crucibulum has a single-layered peridium and white to yellowish peridioles, while those are
