INTRODUCTION

 

Polypores or polyporoid fungi represent an artificial assemblage of wood decaying fungi classified under various orders of Agaricomycetes of Basidiomycota (Kirk et al. 2008; Mycobank 2023). These fungi are characteristic in having annual to perennial, resupinate to effused-reflexed to pileate basidiocarps with gymnocarpic hymenium and poroid hymenophore. Polypores show remarkable variation with respect to micromorphological features such as hyphal system, ancillary structures, basidia and basidiospores. These fungi play vital role in the recycling of carbon due to their ability to degrade lingo-cellulosic substances of the wood. There are reports in literature about the use of fructifications of these fungi for curing many diseases (Dai et al. 2007; Song et al. 2008; Chen et al. 2016; Singh et al. 2016).

Keeping in mind the diverse vegetation and climatic conditions exhaustive fungal forays were conducted in the different parts of Himachal Pradesh, Punjab, and Union Territory of Chandigarh. During these forays some interesting polypore fructifications were collected. Based on details pertaining to macro and micro-morphological characters and comparison with published literature (Singh & Bakshi 1961; Singh 1966; Bakshi 1971; Ryvarden & Johansen 1980; Ding 1989; Roy & De 1996; Leelavathy & Ganesh 2000; Foroutan & Vaidya 2007; Bhosle et al. 2010; Ranadive et al. 2011; Sharma 2012; Ryvarden & Melo 2014; Ranadive & Jagtap 2016; Kaur et al. 2017; Brar et al. 2018; Manoharachary et al. 2022, Vinjusha & Kumar 2022, Index Fungorum 2023; Mycobank 2023) these were identified as Fomes dahlii Henn., Ganoderma tropicum (Jungh.) Bres., G. tsunodae (Yasuda ex Lloyd) Sacc. and Xanthoperenniporia maackiae (Bondartsev & Ljub.) B.K.Cui & Xing. It is pertinent to mention here that Fomes dahlii, Ganoderma tsunodae and Xanthoperenniporia maackiae are recorded as new to India and Ganoderma tropicum as new to Himachal Pradesh and Union Territory of Chandigarh.

 

 

MATERIAL AND METHODS

 

The polypore fructifications were collected during the fungal forays executed in various localities of Himachal Pradesh (28–30 July 2011, 20–23 August 2011, & 02–05 April 2016), Union Territory of Chandigarh (25–28 September 2019 & 07–10 October 2019), and Punjab (15–18 December 2018) (Image 1). The details pertaining to the type and nature of the fruiting body, colour, and appearance of abhymenial and hymenial surface and margins were noted down. The collected specimens were dried in an electric drier at temperature range of 40–45°C and preserved using 1,4-dichlorobenzene in zip lock bags.

 For microscopic details, crush mount and free hand section preparations were made using 3%, 5%, & 10% KOH solutions, Congo red (1% in distilled water), Phloxine (1% in distilled water), Cotton blue (1% in lactophenol), Melzer’s reagent (0.5 g iodine + 1.5 g KI + 20 g chloral hydrate + 20 ml distilled water), and water. The outline of different microscopic structures was drawn using compound microscope at 100x, 400x, and 1000x with the help of camera lucida.  The colour standards are cited as per Kornerup & Wanscher (1978). The identified specimens were submitted to the Herbarium, Department of Botany, Punjabi University, Patiala (PUN).

Remarks: This species is peculiar in having resupinate to effused-reflexed fructifications with dimitic hyphal system and smaller, truncate basidiospores. It was earlier placed in genus Perenniporia and has been reported to cause white rot (Ryvarden & Melo 2014). As per Mycobank (2023) this species is distributed in China and Russia.

 

 

Discussion

 

Among polyporoid genera being described presently the genera Ganoderma and Fomes have received greater attention of the mycologists due to their medicinal importance (Lee 2005; Joseph et al. 2009). The genus Ganoderma has been documented with 58 taxa while Fomes sensu stricto has been reported with only two taxa across India (Ranadive et al. 2011; Sharma 2012; Ranadive & Jagtap 2016; Manoharachary et al. 2022; www.fungifromindia.com). As far as the genus Xanthoperenniporia is concerned, one of the species, i.e., X. tenuis has earlier been described under genus Perenniporia from India. The review of literature indicated account of 27 taxa of genus Ganoderma and one taxon each of genus Fomes and Xathoperenniporia from Himachal Pradesh, Punjab and Union Territory of Chandigarh. The present studies have added one species each to the list of Indian records of the genus Ganoderma, Fomes, and Xanthoperenniporia while Ganoderma tropicum has been described as new to Himachal Pradesh and Union Territory of Chandigarh.
