Saagaromyces
ratnagiriensis
(S.D. Patil & Borse) K.L. Pang & E.B.G. Jones, Mycol. Progr. 2: 35 (2003)
Sordariomycetes, subclass Hypocreomycetidae
Microascales
Halosphaeriaceae
Sexual morph: Ascomata 300-6560 µm high, 400-800 µm in diam., ellipsoidal, immersed, ostiolate, papillate, coriaeous, hyaline, main axis sometimes horizontal with a lateral, recurved neck. Peridium 25-40 µm thick, cells forming pa textura angularis, merging with the pseudoparenchyma of the centrum. Necks about 1mm long, 100-160 µm in diam., cylindrical, emerging with whitish, fuzzy tips over the wood surface, centrally or laterally inserted, ostiolar canal periphysate. Asci 250-340 x 50-68 µm, 8-spored, clavate, pedunculate, untitunicate, thin-walled, thicker below the apex, persistent, with a refractive lens-shaped apical plate, 3-6 µm in diam., 0.8 µm thick, developing at the base of the ascomata venter. Ascospores 48-64-71.4 x 22-28 µm, ellipsoidal, 1-septate, slightly constricted at the septum, hyaline, with apical-subapical appendages. Appendages bipolar, hamate, at maturity uncoiling to form long thread-like filaments.
