A study on the genus Candolleomyces (Agaricales: Psathyrellaceae) from Punjab, Pakistan.

ABSTRACT: Many basidiomata of the genus Candolleomyces were found on sandy and loamy soil from the Indus Riverbed, Kot Addu District. A phylogenetic study was conducted to examine the occurrence of Candolleomyces sindhudeltae sp. nov. using a combination of ITS and LSU regions. Our morphological, anatomical, and phylogenetic studies indicated the novelty of Candolleomyces sindhudeltae sp. nov. The distinguishing features of C. sindhudeltae are convex to campanulate and areolate pileus with scalloped to cracked cap margins, branched, and pale reddish lamellae, greenish-brown ellipsoid to ovoid basidiospores, polymorphic cheilo, and caulocystidia. The novel taxa formed independent phylogenetic relationships within the genus Candolleomyces. The addition of our new species to the genus Candolleomyces makes us confident that the genus was separated from Psathyrella accurately.

Project description:BackgroundWetlands are biologically diverse and highly productive ecosystems that support one-third of all threatened and endangered plants of the world. Wetland plants have been studied ethnobotanically much less than terrestrial plants, including in Pakistan, thus information about the uses of local wetland plants in traditional healthcare system is scare. Head Maralla is a non-recognized wetland with diversified flora that has been focused of the current study.MethodsThe ethnobotanical data were collected from four sites viz., River Tavi, Upstream Chenab, River Manawarwala Tavi, and Bhalolpur through questionnaire and interviews during field trips. Quantitative indices including informant consensus factor (ICF), cultural significant indext (CSI), relative frequency of citation (RFC), and use value (UV) were used to analyze the data.ResultsOn the whole, 119 plant species were identified belonging to 54 families, of which 87 species were dicot, 12 monocots, 11 aquatic, 5 ferns, and 4 species were bryophytes. Of these, 50% of the plant species were utilized for therapeutic purposes, followed by leaves which had more than 20% usage of total consumption. Herbs were the primary source of medicine (73 spp) followed by trees (22 spp), weeds (11 spp), shrubs (9 spp), foliose (2 spp) and thaloids (2 spp) in the area. Fic ranged from 0.66 to 0.93 for constipation and respiratory disorders with an average Fic of 0.87 reflecting a high consensus among the informants about the use of plants to treat particular ailment. Major ailments viz., urination (14%), cough (8.40%), cold (6.70%), stomach (5.90%), asthma (5.90%), skin infection (5%), constipation (5%), and diarrhea (4%) etc., were treated with local plant recipes. The highest CSI value was found for A. vesica (7.55) widely used in respiratory disorders and in digestive problems. RFC ranged from 0.92 to 0.15 with the maximum value obtained for R. communis (0.95). The use values ranged from 0.03 to 0.90 with the maximum use value for R. communis (0.90). A positive correlation was found between CSI and RFC (r = 0.29), and CSI and UV (r = 0.29). The JI values ranged from 7.14 to 0.14 indicating strong affinity with Samahani valley, Azad Kashmir, Pakistan. Unique species Osmunda regalis was first time reported from Pakistan with novel uses for renal and blood purifier. Fifteen percent (15%) plants contribute as fodder species consumed by local community for livestock while almost 6.7% species were utilized for timber and fuel purposes.ConclusionThe ecosystem of Head Maralla provide a complex habitat for aqauatic, terrestrial, and agriculture wetland vegetation. It is suggested that conservation efforts should be made to conserve the ethnoecological knowledge of these areas and pharmacological studies should be conducted for noval drug synthesis in future.
