Coltriciella minuscula sp. nov., a new species of poroid fungus on Pinus merkusii from an Indonesian tropical forest

Abstract

Coltriciella minuscula sp. nov. is described and illustrated from a specimen collected on Pinus merkusii from Bogor, Indonesia. This species is characterized by the size of its basidiocarp up to 4 mm in diam, with long hair on the stipe and with ornamented spores. Both morphological distinctiveness and phylogenetic separation based upon analyses of nrDNA ITS sequences support the establishment of this new species. Morphological dissimilarities between C. minuscula and closely related species are discussed.
