Cophinforma eucalypti

Cophinforma eucalypti Doilom, Jian K. Liu & K.D. Hyde, in Liu et al., Fungal Diversity 57(1): 174 (2012)

MycoBank: MB 801316

Etymology: Referring to the host “Eucalyptus sp.,” on which the fungus was collected

 

Saprobic on recently fallen wood. Ascostromata (88- )112–125(−130) μm high × (135-)172–185(−195) μm wide ( = 112 × 165 μm, n = 10), initially immersed under host epidermis, becoming semi-immersed to erumpent, breaking through cracks in bark, gregarious and fused, uniloculate, globose to subglobose, membraneous, visible white contents distinct when cut, ostiolate. Ostiole (33-)43–52 μm high, (31-)40–48 μm wide, central, papillate, pale brown, relatively broad, periphysate. Peridium (13-) 28–34 μm wide, broader at the base, comprising several layers of relatively think-walled, dark brown to black-walled cells arranged in a textura angularis. Pseudoparaphyses hyphae-like, numerous, embedded in a gelatinous matrix. Asci 74–90(−123)×17–23 μm ( = 89 × 20 μm, n = 10), 8- spored, bitunicate, fissitunicate, clavate to cylindro-clavate, sometimes short pedicellate, mostly long pedicellate, apex rounded with an ocular chamber. Ascospores 21–26 × 8– 11 μm ( = 23.5 × 9 μm, n = 20), overlapping uniseriate to biseriate, hyaline, aseptate, ellipsoidal to obovoid, slightly wide above the centre, minutely guttulate, smooth-walled. Asexual state not established.

Culture characteristics: Ascospores germinating on PDA within 8–15 h. Germ tubes produced from both ends of the ascospore. Colonies growing on PDA 80 mm diam after 3 d at 25–30 °C, fast growing; fimbriate, flat or effuse, dense, initially white after a few days becoming pale grey starting form the centre, finally dark grey to black, convex with papillate surface, reaching the edge the Petri dish after 4 d.

Material examined: THAILAND, Chiang Rai Province, Muang District, Thasud Sub District, on dead branch of Eucalyptus sp., 5 October 2011, M. Doilom, (MFLU 12– 0752, holotype), ex-type living culture MFLUCC 11–0425; Ibid., living culture MFLUCC 11–0655.
