Two lignicolous species of Pleurostoma with stipitate ascomata.
(A–C) Pleurostoma candollei: Ascomata. (D–J) Pleurostoma ootheca: (D) Vertical section of the ascoma. (E, H) Polysporous ascus with a bristle-like appendage. (F, I, J) Polysporous asci (arrows point at the robust stipes attached to cells on ascogenous hyphae and indicate thickening at the apex). (G) Polysporous ascus with a conspicuous thickening (arrow points at the asymmetrically thickened apex). DIC (D, G), PC (E, F, H–J), bar = 100 μm (A–C), 50 μm (D), 5 μm (E–J). J.F. 06057 (A, B), M.R. 3559 (C), K 122386 holotype of P. ootheca (D, G), K 122385 (E, F, H–J).
