Abstract

A new species of Taiwanascus, T. samuelsii, was collected from southern parts of Western Ghats on dead branches of Anacardium occidentale and is described. The new cleistothecial ascomycete is different from the type and only species in Taiwanascus, T. tetrasporus, in cleistothecial size, setae, and ascospore characteristics.

Highlights

  • The southern parts of the Western Ghats are rich and diverse in fungi due to the diverse forest ecosystem, geography, and climatic conditions

  • During early November 2011 an expedition was made to natural forests and plantations of Karadka village DQG DGMRLQLQJ DUHDV VSHFL¿FDOO\ QRUWKHUQ .HUDOD ZKHUH QR mycologists have ever surveyed for microfungi

  • We discovered a rare specimen of Niessliaceae that forms cleistothecial ascomata with stellate setae

Summary

INTRODUCTION

The southern parts of the Western Ghats are rich and diverse in fungi due to the diverse forest ecosystem, geography, and climatic conditions. During early November 2011 an expedition was made to natural forests and plantations of Karadka village DQG DGMRLQLQJ DUHDV VSHFL¿FDOO\ QRUWKHUQ .HUDOD ZKHUH QR mycologists have ever surveyed for microfungi. During this survey, we discovered a rare specimen of Niessliaceae that forms cleistothecial ascomata with stellate setae. The family Niessliaceae was established by Kirschstein (1939) to accommodate a group of taxa having small, dark, VXSHU¿FLDO VDSURELF VHWRVH SHULWKHFLRLG DVFRPDWD /DWHU the new genus Taiwanascus (Sivanesan & Chang 1997) was described with the following characteristics: cleistothecial ascomata with aseptate setae, brown, thick-walled, straight, smooth, and more or less 2–6 times dichotomously branched at their apex with the upper branchlets possessing somewhat darkly thickened, minute denticles. The characteristics of the only known species, T. tetrasporus, were consistent with those of the Niessliaceae (Samuels & Barr 1997)
