Fandri Sofiana Fastanti, Suharja, Roland Putra Pribadi Ahmad, & Atik Retnowati 2026. Nitidochapsa leprieurii (Ostropales, Graphidaceae): A New Notes Lichen from Moluccas and Kalimantan, Indonesia. Floribunda 9(1) 22—26 — Nitidochapsa is one of the genera in Graphidaceae, which has the largest number of species in the crustose group. This genus is distri-buted in the pantropical region, including Indonesia. Field collections were conducted in Halmahera (North Moluccas) and Sangatta (East Kalimantan) from various habitats. Specimens were observed growing epiphytically on tree bark and branches. Species identification was based on the morphological characters of the thallus, apothecia and supported by microscopic examination of ascospores and other anatomical features. As a result, Nitidochapsa leprieurii is reported here as a noteworthy lichen species newly reported from Moluccas and Kalimantan. This record extends the known distribution of the species within Southeast Asia and contributes to the lichen diversity in Indonesia. The discovery also emphasizes the importance of continued lichenological exploration in under-studied regions such as North Moluccas and Kalimantan. Information on morphology, anatomy, and distribution is provided to support future studies and conservation efforts.
