Abstract: The tropical region, which has the highest macrofungi diversity, has not been fully exploited instead of this is an important component of the global diversity. However, no work has been carried out to assess such diversity in Tripura. Since tropical forests are diverse in plant composition and structure, hence the objective of this study was to explore the mushroom species richness in Tripura, Northeast India with the aim of producing a checklist along with their present geographical distributions, key identification characters and valid photographs. Field surveys and collection of mushrooms were carried out in Tripura covering different sites during 2015–2018. Data on macrofungal diversity, distribution patterns and taxonomic identification were analyzed. A total of 217 wild mushrooms were documented from eight districts of Tripura, northeastern India. Out of 217 samples, 202 samples were identified up to the genus level, 125 samples were identified up to the species level.  A total of 76 genera belonging to 60 families and 25 orders were classified in this ecological study. The majority of macrofungi belong to the family Polyporaceae (30 nos), and order Agaricales (103 specimens). The wild macrofungi were collected from 56 sites of eight districts of this state and the maximum macrofungi diversity was recorded from Sepahijala District. Present findings also observed that the maximum wild fungi of this state grow on different plant parts. This is the preliminary study on documentation of wild macrofungi from eight districts of Tripura, northeastern India and it will be used as a reference database of wild mushrooms of this state, which will also help in future research work in different fields.

INTRODUCTION

 

Fungi have been known from (the fossil records) the Silurian period according to archaeological evidence (408–438 million years ago) in the Paleozoic era and the diversity of fungi had improved by the Pennsylvanian period 286–320 million years ago (Alexopoulos et al. 1996). Fungi are one of the diverse kingdoms of eukaryotes and important major biological constituents of forest ecosystems. It is important to understand their existence on plant communities, their ecological functions and their impact on nature (Martin et al. 2011). Mushrooms can be defined as macrofungi having unique fruiting bodies which are either epigeic or hypogeic, visualized by the naked eye and are easily handpicked (Chang & Miles 2004). Hence, Hawksworth (2001) has anticipated that 0.14 million species created fruiting bodies of adequate shape, size, and appropriate structure to be considered as macrofungi i.e., mushrooms out of the 1.5 million studied fungi based on Chang & Miles (2004). These studies have stressed the importance of macrofungi in nature preservation and forestry organization different from agroecosystems (Straatsma et al. 2001). Ecologically, fungi can be classified into three groups—saprophytes, the parasites, symbiotic or mycorrhizal and endophytic species. Most of the terrestrial macrofungi are saprobic, mycorrhizal symbionts, but some of them are pathogens of plants or other fungi.

According to Manoharachary et al. (2005) India is enriched with mushroom flora as one-third of the fungal diversity of the globe exists in India and only 50% of these have been characterized till date. Northeastern India is also very richin macrofungal diversity (Verma et al. 1995) and very few reports on macrofungal diversity have been carried out in the northeastern region of India (Das 2009 and 2010; Tanti et al. 2011; Tapwal et al. 2013). This study to collect, document, and classify the macrofungi was undertaken to fill this data gap. Tripura is one of the seven states in the northeastern part and the third smallest state of India with a geographical area of 10,491km2, of which 6,292km2 (59.98%) is forest area as per legal classification in the state.  Tripura situated between 23.8400N and 91.2800E.  The fruiting bodies of mushroom species grow only under precise conditions, including geographic location, elevation, temperature, humidity, light, pH, nutritional sources (carbon and nitrogen sources) and surrounding flora (Swapna et al. 2008).

The existence or nonexistence of mushrooms species is a potential indicator to assess the deterioration or the development of an ecosystem and they also play an important role in nutrient reprocessing, growth and establishment of plants in forests (Tapwal et al. 2013). Literature survey concerning the documentation of macrofungi revealed that there are meager reports available from northeastern India. The field documentation of macrofungi from Tripura remains unexplored till today. Therefore, the main intention of the current study was to identify wild macrofungi up to species level and to document their distribution in natural habitats. Thus, the specific goal of this study was to prepare a checklist of macrofungi in different districts of Tripura, northeastern India and also to raise awareness among people to conserve macrofungi for future generations and to maintain the ecosystem’s diversity.

 

 

MATERIALS AND METHODS

 

Study area

The current study was conducted in eight districts of Tripura namely, Dhalai, Sipahijala, Khowai, Gomati, Unakoti, North Tripura, South Tripura, and West Tripura (Figure 1).

 

Collecting sites

Included undisturbed forest, secondary forests, roadside, plantations, crop fields, jhum fallow and agriculture lands.  The samples were collected through simple random sampling method from different sites, which is an unbiased surveying technique and each specimen was chosen randomly and entirely by chance during the rainy season of 2015–2018.

 

Mushroom collection

Macrofungi were collected carefully by using forceps or trowel from their natural habitats. Photographs were taken and information such as date of collection, locality, habitat, colour, odour, test, size and shape of the specimen in their natural condition were also recorded as field notes (Table 1). Each sample was given specific laboratory accession number—Mushroom Culture Collection Tube (MCCT) for future reference and identification. After collection, all specimens were wrapped in a paper envelope and cautiously taken to the newspaper sheet and labelled systematically as per given MCCT #. Specimens were dried in a hot air oven at 45–55oC for 48hr and then samples were preserved in sealed polyethylene bags by adding 1, 4-dichlorobenzene (Debnath et al. 2017). All dry mushroom samples were deposited in the Mycology & Plant Pathology Laboratory, Department of Botany, Tripura University for future reference.

 

Identification of wild mushrooms

Wild mushrooms were identified morphologically based on the available literature, viz., Pegler (1977); Purkaystha & Chandra (1985); Weinstein et al. (2002); Castellano et al. (2003); Hall et al. (2003); Rogers et al. (2005); Antonín & Buyck (2006); Desjardin & Ovrebo (2006); Wei & Yao Tang (2009); Senthilarasu (2013a,b); Karun & Sridhar (2013); Moore & O’Sullivan (2014); Semwal et al. (2014). We also considered available webresources (http://www.mushroomexpert.com/major_groups.html; http://www.mycokey.com/newMycoKeySite/MycoKeyIdentQuick.html; http://qldfungi.org.au/ etc.) for identification and confirmation of wild mushrooms.

 

 

RESULTS

 

Morphological identification and processing

In this study, macrofungi were randomly collected from 56 different sites under eight different districts of Tripura. Among these eight districts,the maximum number of mushroom specimens, i.e., 62 different mushrooms were collected from Sepahijala District followed by West Tripura (55), South Tripura (39), North Tripura (18), Gomati (14), Khowai (9), Dhalai (4), and Unakoti (4) (Figure 1). Sepahijala District ishighly diverse sincethis area contains two wildlife sanctuaries (Sepahijala and Trishna) which were protected and undisturbed areas.  Mushroom specimens were identified on the basis of their morphometric characteristics. All information about wild mushrooms such as scientific name, location, habitat, district name and distinguishing characters are presented in Table 1 and the photographs are presented in Image 1–11.

This study revealed that these mushrooms were recorded for the first time from this region. A total number of 217 macrofungal species were documented of which 202 were identified at genus level and 15 macrofungal specimens remain unidentified (Table 1). The geographic distribution of all 217 macrofungal species (as per serial number mentioned in Table 1) throughout the study area was shown in Figure 2.  Most of the wild mushrooms recorded inthis study were found to grow on dead wood.

In this study, a total of 77 genera belonging to 42 families and 16 orders were considered for ecological studies. Among the collected samples, majority of macrofungi belong to the family Polyporaceae, which contained 30 species and nine genera (Figure  3). The dominant genus was Lentinus which contain 12 morphotypes and Marasmiellus, Pleurotus were the second and third dominant genus which contained 11 and nine morphotypes, respectively (Figure 4). Agaricaceae and Marasmiaceae were found to be second dominant families because both families contained 21 species each belonging to eight and four genera, respectively. On the other hand, order Agaricales contained the maximum number of macrofungal species, whereas Polyporales and Russulales are the second and third dominant orders (Figure  5).

Present observations showed that fungal diversity also depends on their substrates. The maximum numbers of wild mushrooms of this state easily grow on dead wood during the monsoon, winter, spring and summer seasons. In this study 31 types of habitats were observed  and these were catagorised into four groups namely, different plant parts (bark of  living plant, dead  wood, dead root, decaying paddy straw, decaying rice bran, decomposed wooden dust, bamboo rhizome, dead decaying wood, dead leaf, dead wooden bark, decaying bamboo, decaying plant, sawdust, living plant, decaying leaf, dead plant, decaying wood, dead wood), decomposed soil (decaying wood with soil, decomposed grass, soil with decaying paddy straw, soil with decomposed plants, soil with decaying  leaf), soil (ground in open grassy field soil, sandy soil, soil with bryophyte association, soil with grass field, termite mounds) and cow dung (Figure  6). Some interesting substrates were noticed, which were specific to certain genera. These interesting habitats of macrofungal genera were living plant for Lentinus, Polyporus, Pleurotus, Xerulina, Marasmiellus, soil with bryophyte association for Hygrocybe, bamboo rhizome for Parasola, Psathyrella, dead wooden bark (crack tissue) for Xylaria and termite mounds for Termitomyces and Humaria. This divergence of habitats may be due to their nutritional needs and the need for a suitableenvironment to survive.

 

 

DISCUSSION

 

The present study revealed that a total of 217 different morphotypes were collected from eight different districts of Tripura and 55 mushrooms were collected from West Tripura District, whereas previous findings (Debnath et al. 2017) showed that West Tripura contained 22 morphotypes. There are few reports on mushrooms in Tripura (Debnath et al. 2017, 2019, 2020a,b) but a study on mushroom diversity of the state of Tripua has not been conducted earlier. Baptista et al. (2010) recorded a total of 2677 carpophores belonging to 73 species across 16 families and 23 genera in the Tra´s-os-Montes region of Northeast Portugal, which also showed more or less dissimilarity with our finding. According to Cho et al. (2019), they documented 95 macrofungi that belong to 57 species, 47 genera, 24 families, and 8 orders in Ascomycota and Basidiomycota from the Inner Tian Shan in Kyrgyzstan located in China and the dominant species belonged to the families Polyporaceae (8 species) and Agaricaceae (6 species), respectively. A large number of fungi was reported from moist deciduous and wet evergreen forest of Andaman &Nicobar Islands based on existing literature; a total of 446 fungal species was reported which belong to 216 genera, 96 families, 44 orders 10 classes and seven phyla (Niranjan & Sarma 2018).  Tapwal et al. (2013) also recorded 30 macrofungal species representing 26 genera belonging to 17 families which were collected from six different sites in wet ever green tropical forest of Assam, India. A total of 71 species of 41 genera belonging to 24 families were recorded including 32 edible, 39 inedible and altogether 19 medicinally potential mushrooms were collected from tropical evergreen and deciduous mixed type of forest in Gurguripal Eco-forest, Paschim Medinipur, West Bengal, India (Singha et al. 2017). The present study showed that the Polyporaceae family was dominant which also showed resemblance with other findings (Tapwal et al. 2013). Priyamvada et al. (2017) documented a total of 113 macrofungal species belonging to 54 genera and 23 families and the highest species were recorded in the family Agaricaceae followed by Polyporaceae and Marasmiaceae. Present findings revealed that maximum numbers of macrofungi were growing on different plant parts in comparison to soil habitat (Debnath et al. 2017). 

The distribution and abundance of wild macrofungi are influenced by natural factors (Swapna et al. 2008), like rains and accessibility of decomposed organic matters (Debnath et al. 2017). The occurrences of mushrooms in forest bed and plantation site suggest a close association between the macrofungal population and physical condition of forest (Debnath et al. 2017). Most of the fleshy and gilled macrofungi were recorded in the rainy seasons as this period is favorable for their production since there is adequate moisture, favorable temperature, relative humidity and sunshine, which also aids the macrofungi in the decomposition of dead organic matter. While polypores can grow in all the seasons because they require less rainfall, i.e., moisture and relative humidity, high temperature and sunshine are also favorable but most of the macrofungi cannot survive these exceptional conditions. According to Payton (1993) the high macrofungal diversity was found in high altitude because of low temperature, soil moisture and high relative humidity which directly affected the forest ecosystem found on the mountains. Present documentation reports that the total 217 macrofungi were collected from 56 sites under eight districts of Tripura. Most wild mushrooms of this state grow on dead wood. Maximum mushroom specimens were collected from Sepahijala District of Tripura but collection was highest in West Tripura.Occurrence and diversity of wood inhabiting macrofungi (some of them listed in Table 1) was studied along with details of host ranges in central India. In the study, Phellinuswas recorded as the most diverse genus with 18 species followed by Trametes and Ganoderma 17 species each, Polyporus seven species, Microporus five species, Daedelea, Hexagonia and Hymenochaetefour species each. Schizophyllum commune, Tremates cingulata and Flavodon flavus were common to all places and showed the maximum frequencies of occurrence (Tiwari et al. 2013). Diversity of two groups of mushrooms belonging to Amanitaceae and Russulaceae were studied.Mushrooms belonging to Amanitaceae (80 species) were reported from different parts of India including four genera—Amanita(73), Catatrama(1), Limacella(4), and Saproamanita(2). Maximum diversity of Amanitaceae were recored from Uttarakhand followed by Himachal Pradesh, Kerala, Odisha, Jammu & Kashmir, Meghalaya, Madhya Pradesh and West Bengal (Verma & Pandro 2018).

 

 

CONCLUSIONS

 

This is the earliest ever organized study on documentation of wild macrofungi from Tripura, northeastern India and this study also provides the baseline information for the researchers to do various studies on these mushrooms in future. The findings of this study will be a reference database of wild mushroom of the state and will help in future research work in different fields. The significance of macrofungal diversity is not only for the ecosystem but also for human diet and health, which are also necessary reasons for conservation, however, the different biological activities, cultivation techniques and economic importance of some selected mushrooms are yet not known to us, therefore further research is needed to develop various cultivation techniques and also to isolate the functionally active components of these wild mushrooms.
