Diversity and Distribution of Macro Fungi in Some Selected Parks and Gardens of Dhaka City, Bangladesh

Abstract

A survey was conducted during June to November, 2017 in five selected parks and gardens of Dhaka city, Bangladesh namely National Botanical Garden, National Zoo, Romna Park, Dhanmondi Lake and Boldha Garden. The investigation was done to analyze the morphology, diversity and distribution of macro fungi A total of 44 macro fungi samples were collected and identified to 32 species under 18 genera and 18 families. The most frequent collected genera were Ganoderma sp., Daedeleopsis sp., Ramariopsis sp., Crepidotus sp. and Daldinia sp. The maximum frequency of identified species was exhibited by Ganoderma lucidum (9.46%), followed by Ganoderma applanatum (8.1%), Volvariella volvacea (5.41%), Agaricus bisporus (5.41%) Daedaleopsis confragosa (4.05%), Trametes versicolor (4.05%) and Ganoderma boninense (4.05%). The maximum density of occurrence among collected samples was exhibited by Ramariopsis kunzei (11.3%), Ganoderma lucidum (9.9%), Crepidotus variabilis (5.3%) and Daedaleopsis confragosa (3.76%). The predominant species found in National Botanical Garden is Ganoderma applanatum, in Ramna Park is Ganoderma lucidum, in Dhanmondi Lake is Ramariopsis kunzei, in Boldha Garden is Ganoderma lucidum and in National zoo is Amanita bisporigera. The collected specimens were deposited to the Sher-e-Bangla Agricultural University Herbarium of Macro Fungi (SHMF).

Diversity, Distribution and Morphological Characterization of Wild Macro Fungi from Gajni Forest

“…This species was also reported on Acacia auriculiformis [28] and on Dalbergia sissoo [29]. Ganoderma applanatum was found in National Botanical Garden, Dhanmondi Lake and in National Zoo [30]. Ganoderma species was also reported in India [31,22] and China [32].…”

Occurrence, diversity and morphology of poroid wood decay by Ganoderma spp. from tropical moist deciduous forest region of Bangladesh

“…This species was recorded from national botanical garden, Dhaka with a density of 5% (Rubina et al, 2017). Ganoderma lipsiense was found in National Botanical Garden and in Romna Park also with the frequency and density 2.70% and 1.5%, respectively (Tanni et al, 2020). On the other hand, Ganoderma lipsiense was also reported from India in association with Dalbergia sissoo plant (Bhosle et al, 2010;Dwivedi et al, 2012) and in China (Wang et al, 2012).…”

“…The density of its presence was 20%. Ganoderma applanatum was found in National Botanical Garden, Dhanmondi Lake and in National Zoo also in association with Azadirachta indica (Neem) with the frequency of 1.35-4.05% and density 1.5-3.76% (Tanni et al, 2020). In a study Moncalvo & Ryvarden, (1997) published a world list of Ganoderma species.…”

“…On the other hand, Ganoderma pfeifferi was also reported in India (Bhosle et al, 2010;Dwivedi et al, 2012) and in China (Wang et al, 2012 . Ganoderma tsugae was found in National Botanical Garden, Romna Park, Dhanmondi Lake and in National Zoo associated with Swietenia macrophylla (Mehogani) tree (Tanni et al, 2020). In other study (Rubina et al, 2017) recorded it's density 10% in national botanical garden, Dhaka.…”

“…Among the species, the highest frequency of Ganoderma tsugae was 33.33% and the density was 95% (Rashid et al, 2017). Ganoderma lucidum was found in every survey area associated with Azadirachta indica (Neem) (Tanni et al, 2020). But another finding described the species from Bogra district under social forest region of Bangladesh with a frequency and density of 75% and 25% respectively.…”
