MORELS OF WEST JAVA : DESCRIPTION AND POTENTIAL UTILIZATION

<p class="PythagorasAbstractBodyEnglish">The genus Morchella or known as morels is one of the most popular edible mushrooms around the world. Information regarding the distribution and cultivation of this fungus are mostly from the temperate country. In Indonesia, to date only 2 reports of the distribution of this mushroom have been found, at Mount Rinjani West Nusa Tenggara (2012) and Mount Klabat Minahasa Utara (2019). Since then, there have been no report of this macrofungi in Indonesia. In 2020, local people ( the members of the Indonesian mushroom hunting community) shared the information about the appereance of Morchella at residence area near Mount Gede Pangrango, West Java. Morphological identification which completed by the description and macroscopic characterization confirmed the identity of the macrofungi as Morchella sp. Further observation using microscopic characters and / or DNA data needs to be done to confirm the taxonomic position to the species level in the future studies. This information adds to the recording of Morchella distribution and its potential use in Indonesia.</p><p><strong>K</strong><strong>eywords</strong>: <em>Inventory, Macrofungi, Indonesia, Morchella</em><em></em></p>

Chlorophyll and Carotenoid Level Comparisons of Pigeon Orchid (Dendrobium crumenatum) in Water and Light Stress Treatment

Environtmental conditions in which plants grow are always changing which when exceeding the tolerance limit will result in stress. Water and light stress affect the pigment content of photosynthesis such as chlorophyll and carotenoids. <em>Dendrobium crumenatum </em>is one of orchid species that is judged to be resistant to various types of environtmental conditions, so it can grow well in any environtment. This research aims to determine the comparison of chlorophyll and carotenoid levels of <em>D. crumenatum </em>from Bantul lowland population, Special Region of Yogyakarta which is given water and light stress treatment. The methods used are extraction with alcohol solvent (96%) and absorbtion level measurements with spectrophotometry at wavelengths 470, 645, and 663 nm. The highest chlorophyll a level contained in the leaves of <em>D. crumenatum </em>which is given water stress treatment, highest chlorophyll b level in control plant, highest total chlorophyll in the leaves which is given water stress treatment, and highest carotenoid level found in the leaves which is given light stress treatment.
