Abstract

In order to explore the biodiversity of mushrooms from Pakistan, authors come across a new Humaria sp. associated with Pinus wallichiana from Pakistan’s part of Himalayan moist temperate forests. Morpho-anatomical and phylogenetic characterization were used to elucidate their taxonomic affinities. Morphological and phylogenetic analysis confirms that it is a new species of Humaria. Humaria laevispora is subsequently described in detail and compared to closely related taxa Humaria hemisphaerica. The analysis also reveals that epigeous Humaria sp. is sister to hypogeous Genea spp. reflecting epigeous habit in Humaria a derived condition. Bangladesh J. Plant Taxon. 28(2): 379-384, 2021 (December)

Highlights

Peziza species having hairs and setae on apothecial margins and receptical surface were termed as “Lachnea” by Fries (1823)
The presence or absence of these hairs served as a base for identification under Lachnea,while other important characters, like surface morphology, hair origin, shape, color in the ectal excipulum, shape of apothecia, hymenialcolor, ascospore surface morphology and guttulation were ignored by the earlier workers
From Pakistan, three Humaria species have been reported based on morphology viz., H. gregaria, H. hemispaerica and H. woolhopeia (Ahmad et al, 1997), while no species on the phylogenetic basis has been documented from Pakistan so far. This is the first time from Pakistan that one new species of Humaria is described based on the molecular and phylogenetic basis. This new species of Humaria was collected during monsoon season of 2015 from Khanspur, Ayubia (KP) of Pakistan which lies in moist temperate west Himalayan mountainous range

Summary

Introduction

Peziza species having hairs and setae on apothecial margins and receptical surface were termed as “Lachnea” by Fries (1823). Fuckel (1870) transferred P. hemisphaerica to Humaria. Humaria hemisphaerica (Wiggers ex Fr.) Fuckel, producing cupulate apothecia, was accepted in the tribe Lachnes of the family Pezizés (under Cupules). Sixteen species of Humaria Fuckel have been reported from north temperate regions all over the world.
