Abstract

Climacodon roseomaculatus is a fleshy species of Polyporales with a hydnoid hymenophore. The species’s distribution in Indonesia was reported six times from 1923 to 1961 from West Java and East Java collection to date, there have been no following updates on the collection and occurrence status of C. roseomaculatus in Indonesia. During a fungus foray in 2023, some red to pink basidiomata of Climacodon were spotted in Semarang, Central Java, Indonesia. The current study aimed to determine the taxonomical position of Climacodon BO24632 based on morphological evidence. Fresh materials were used for the investigation of macro- and micromorphological characters. The result showed that Climacodon BO24632 was identified as C. roseomaculatus based on distinctive features of stipe and gleocystidia. Climacodon roseomaculatus BO24632 is closely related to C. sanguineus with blood-red to pink basidiomata, cylindrical spines of hymenophores, and ellipsoid basidiospores. However, the former species lacks a well-developed stipe and has thin to thick-walled gloeocystidia. This study is the first report on the distribution of C. roseomaculatus from Central Java, Indonesia. In addition, the current work is the latest information and herbarium collection of C. roseomaculatus after more than fifty years of hiatus in Indonesia. We expect that the same species also occur in many different locations in Indonesia; thus need a warrant of collections.

Abstract

Termitomyces are known as wild edible mushrooms that are commonly consumed in Africa and Asia. T. eurrhizus can be easily found in many areas in Indonesia. However, the recent collection and proper documentation of this species has not been done in Indonesia. In addition, the potential utilization of this species needs to be revealed. This research aims to identify, investigate the proximate value, and test the antibacterial activity of T. eurrhizus. The exploration was carried out at the IPB University campus forest using an opportunistic sampling method. Fresh basidiomata were used for morphological identification. Proximate analysis was done following AOAC method. Mushroom extract was subjected to antibacterial test against Enteropathogenic Escherichia coli. Our specimen was identified as T. eurrhizus based on pileus characters (macroscopically) and spore features under an electron microscope (microscopically). The proximate result showed that the moisture content was 13,70 %, the ash 13,66 %, total fat content 2,05 %, total protein content 27,73 % and fiber content 8,49 %. The investigated antibacterial was evaluated based on size of antibacterial zone for concentration 200 mg/ml extract (3,5 mm), 100 mg/ml (6,5 mm), 50 mg/ml (3,83 mm), 25 mg/ml (2,5 mm), and 12.5 mg/ml 6,33 mm. Our result showed the potential utilization of T. eurrhizus as nutraceutical food and antibacterial. Further research is expected to collaborate with various cultivation or product development fields.
