NOV., A NEW ASCOMYCETE FROM INTERTIDAL MANGROVE WOOD BY K. D. HYDE AND R. MO UZOURAS S chool of Biological Sciences, Portsmouth Polytechnic, King Henry I Street, Portsmouth POI zJ)Y, England A loculoascomycete, Passeriniella sauoryellopsis sp. nov ., is described from intertidal mangrove wood of Rhizophora mucronata and Xylocarpus granatum. During a study of the manglicolous fungi from the Seychelles, an unidentified bitunicate ascomycete was collected from mangrove wood . The ascospores resembled those of the genus Savoryella Jones & Eaton which is characterized by unitunicate asci and ascocarps without paraphyses (Jones & Eaton, 1969). However, the fungus is best accommodated in the genu s Passeriniella Bed. as it has bitunicate asci and ascocarps with pseudoparaphyses. Passer- iniella sauoryellopsis sp . nov . is described as new and is characterized by having brown ascospores with hyaline end cells, 4-spored asci with an ocular chamber and large ascocarps with p seudopara- physe s. It differs from Leptosphaeria obiones (C rouan & Crouan) Sacc. ,a marine species with similar ascospores (Kohlmeyer & Kohlmeyer, 1979), in the larger size of the a scospores, the nature of the asci and distinctly larger ascocarps. P. saooryellopsis is illustrated by optical and scanning electron micro scopy. Passeriniella savoryellopsis Hyde & Mouz- ouras, sp . nov . (Figs 1-13 ) Etyrn . : From the genus Savoryella and the Greek apsis = appearance, referring to the likeness of the ascospores to those of the genus Savor y ella Ascocarpi 500-700 I'm alti x 800-1300 11m diam, glo- bosi vel subglobosi, in ligno immersi, solitarii vel gregarii, atro-brunnei vel nigri, coriacei, ostiolati et papillati. Colla 300-600 I'm longa x 200-350 I'm diam , nigra, cum periphysibus. Pseudoparaphyses 3.9-5.9 ftmlatae ,numer- osae, ramosae, filamentosae, hyalinae , septatae, Peridium 80-100 pm latum, z-stratosum, stratum exterius ex hyphum rugrum et irregularibusque, in cellularum ligno, stratum interius ex cellulis irregularibusque pachyder- maticis formarum textura angularis. Asci 280- 440 x 24-3 2 um, quattuorspori, cylindrici, pedunculati, pachy- derrnatici , bitunicati (fissitunicati), cum camera apicali, postquam maturescent, endoascus in aqua augens, ascum elongans et in ostii canale expellen s, textura ascogena basale exorientibus. Ascosporae 64-88 x 24-28 I'm, uni- seriatae, ellipsoidcae, triseptatae, in medio constrictae, quarum mediae cellulae brunneae et grandes, polares cellularae hyalinae et parvae. Substratum in ligno putrescenti (Rhizophora mucro- nata, Xylocarpus granatum) in aqua marina. Distributio Oceanus Indicus (Seychelles), Mare Austro-chinensis. Holotypus : IMI 318782, slides 1-10, ex radicibus et ramis ernortuis Rhizophorae mucronatae, Brilliant man- grove, Seychelles, 4 Jan. 1984; isotypus in lignis siccis, Seychelles. Ascocarps 500-700 /Lm high x 800-1300 11m diam, globose to subglobose, immersed in the substratum beneath a thin stroma, solitary or gregarious, dark brown to black, coriaceous, ostiolate and papillate. Neck 300-600/Lm long x 200-350 /Lm diam, black, with periphyses. Pseudoparaphyses /Lm diam, numerous, filamentous, branched, hyaline, faintly septate. Peridium 80-100 /Lm thick, composed of 2 layers , an outer layer ofirregular melanized hyphae amongst host cells and an inner layer of thick-walled irregular cells forming a textura angularis. Asci 280--440 x 24-32 /Lm, 4-spored, cylindrical, ped- unculate, thick-walled, bitunicate (fissit unicate), with an ocular chamber, at maturity, endoascus swelling in water, stretching and pushing the ascus into the ostiolar canal, arising from a basal ascogenous tissue. Ascospores 64-88 x 24-28 /Lm, uniseriate, ellipsoidal, 3-septate, constricted at the central septum, central cells brown, large, end cells small, conical and hyaline. Additional specimens examined: On intertidal mangro ve wood, Kampong Dato Ghandi mangrove, Brunei, May 1985, KDH0003, 0005 ; on exposed buttress roots of Xy/ocarpu s granatum, Kampong Kapok mangrove, Brunei , July 1986, KDH0346--0348. The fungus is best placed in the genus Passer- iniella because of its immersed spherical ascomata with branched, septate pseudoparaphyses (Fig. 6), Trans . Br. mycol.
