MORPHOLOGICAL IDENTIFICATION OF WILD EDIBLE MUSHROOM ( Termitomyces striatus ) AT IPB UNIVERSITY

Indonesia is a tropical country which is famous for its 2 seasons, namely the rainy season and the dry season. In the rainy season, the humidity level will increase and induce the development of mushroom’s fruiting body, including the edible species. The research on wild edible mushroom diversity should be carried out massively in various regions in Indonesia. One of the potential areas is the forest area of the IPB University Campus (HKIU). This study aims to explore and identify wild edible mushroom in HKIU. The mushroom exploration was done


INTRODUCTION
Therefore, it is necessary to explore in order to provide information about the types of mushrooms in the HKIU area and their potential so that it becomes the basis for preserving and developing mushroom cultivation.This research aims to explore and identify edible wild mushrooms in the HKIU area.

Indonesia is known as a tropical country with the largest area of tropical rainforest after Brazil and Congo and has two seasons, namely the rainy and dry seasons.In the rainy season, humidity levels will increase to induce the development of fungal fruiting bodies [1];[2].Fungi are the second largest group of organisms, estimated to consist of 11.7-13.2 million species; however, to date, only 150,000 fungal species have been explored in their entirety [3].Fungi are distributed worldwide and have an essential role in various roles as mycorrhizae, saprotrophs, parasites, and entomopathogens in various ecosystems [3];[4].Fungi are classified as eukaryotic organisms, heterotrophs, characterized by chitin cell walls, reproduce by spores, and can live in various habitats.Fungi have the ability to colonize various habitats with several living mechanisms, such as parasites, endophytes, and saprophytes.Fungi are macroscopic fungi based on the size of the fruiting body.Fungi with large fruiting bodies (Mushrooms) are dominated by the Basidiomycota and Ascomycota Phylla.Macroscopic fungi generally have a fruiting body structure consisting of a cap, stalk, ring, and volva, but some without rings [1];[2].In the identification process, fungi can be characterized based on morphological observations.Fungi usually live on rotting wood, soil surfaces, and litter.The parameters commonly used as references in observing fungi include macroscopic characteristics (shape, color, and texture of the fruit body) [5] and microscopic characteristics (spores, basidia, cystidia, and hyphae).
using the exploration method by exploring the HKIU area [7].The fruiting bodies were found in the HKIU Bamboo Arboretum area.The fungal samples obtained were then measured for their fruiting bodies and documented in situ, and information about the conditions of their growing environment was recorded.

The
Termitomyces striatus has a stemmed fruit body and a cap with lamellae.The texture of the basidiomata was fleshy.The pileus was brownish cream colored with a darker color in the middle, with a pileus diameter of 4.6 cm.The surface of the pileus was slightly slippery when dry and slimy when wet. Pileus has a hood shape with shallow grooves (striated).The character of the margin was split, wavy, and curved downward (Figure 2A-C).The hymenophore type was lamellae, white to cream in color; the lamellae have a free attachment type and gills tightly arranged and attached to the stipe (Figure 2D).The stipe was cylindrical and fleshy; the surface was white, finely striated or longitudinal, fibrous, and attached to the middle of the cap with the stipe 9 cm long and has no rings (Figure 2E).Observation showed that basidiospores were oval to ellipsoid in shape, with sizes ranging from 4 -10 μm, yellowish green, smooth and thinwalled, inamyloid (Figure 3A).The basidia were clavate, and the hyphae are radial with a size of 52.60 μm (Figure 3B) interspersed with basidioles (Figure 3C).Two types of cystidia were found in this study (Figure 3 D, E).The hyphae on the trama are arranged in parallel (Figure 3F).Saprotrophic, found around leaf litter in humid temperature conditions in the Bamboo Arboretum area of the IPB University Campus, West Java (-6.562459,106.725971,March 2023, Nurhakiki, Herbarium (2F), deposited to the Mycology Division Laboratory, Department of Biology, IPB.
