Trichopeltis rhyacoides Stevens n. sp. Ascopores 1-2 or 3-septate shorter and thicker than T. reptans, 7-8 X or X ^, and often breaking apart at the primary septum, obtuse hyaline. Thal- lus bands long, spreading, narrow, usually no more than 45-60/* wide. Cells com- monly 18-25 fi long by 3 ^ wide. Perithecia frequently wider than the thallus, causing it to broaden out. (See PI. vm, G.) On Alyjcia olivaeformis. Hawaii: Kealakekua, July 25, no. 985. The specific name is derived from the Greek word rhyax, a lava flow, on account of the similarity of the thallus bands to flowing lava.
