Description
|
| Habit: |
On submerged woody debris. |
|
| Ascomata: |
Ascomata solitary to gregarious, superficial or immersed in substrate, covered with septate, flexuous, subhyaline hairs, cleistothecial, globose, light brown, (158-)173-415(-436) µm diam, irregularly dehiscing. |
|
| Peridium: |
Peridium pseudoparenchymatous, membranous, semitransparent, light brown, 14.4-24.0(-29.0) µm thick. |
|
| Beak: |
Beak absent. |
|
| Hamathecium: |
Paraphyses absent. |
|
| Ascus: |
Asci 8-spored, elongate at first, becoming clavate, broadest in the middle, stipitate, evanescent, (60-)67-84(-89) x 17.0-24.0 µm. |
|
| Ascospore: |
Ascospores biseriate, at first hyaline, 1-celled, cylindrical and rounded at both ends, then obpyriform, constricted above the middle, becoming transversely 1-septate, the apical cell enlarging and becoming triangular, brown, 21.6-30.0 µm long, 19.0-30.0 µm wide at its broadest, tapering to 2.4-2.8 µm wide, basal cell as though pedicellate, remaining hyaline, thin-walled, (10.4-)12.0-14.4(-15.6) µm, finally disintegrating. Mature ascospores dark brown, thick-walled, triangular, sides often concave, corners rounded, one truncate and bearing a refractile scar at the former point of attachment of basal cell, one bearing a germ pore, and one broadly rounded. |
|
| Sheath: |
Dead hyaline ascospore cell may serve as an appendage. |
|
| Appendage: |
None observed. |
|
| Culture: |
Colonies effuse, floccose, hyaline, becoming greyish black. Mycelium mostly immersed, composed of branched, septate, subhyaline to brown hyphae. ATCC 3634976 |
