Description
|
| Habit: |
Superficial or partly immersed on wood, clustered or scattered. |
|
| Ascomata: |
Ascomata superficial or partly immersed, globose to subglobose, hyaline becoming greyish brown with age, membranous, 130-300 (x=186) x 170-325 (x-221) µm, spherical when young, developing a long cylindrical neck. |
|
| Peridium: |
Peridium membranous, of textura angularis in face view. |
|
| Beak: |
Beaks long, cylindrical, hyaline, periphysate, 81-326 (x=204) x 36-76 (x=39) µm. |
|
| Hamathecium: |
Hamathecium of chains of pseudoparenchyma cells (catenophyses). |
|
| Ascus: |
Asci unitunicate, with 8 overlapping ascospores, fasciculate in base of ascoma, persistent, forcibly discharging ascospores or deliquescent, clavate, with thickened region and pore at apex, cytoplasm constricted below apex, 64-116 (x=94) x 14-38 (x=28) µm. |
|
| Ascospore: |
Ascospores hyaline, thick-walled, one septate, forcibly discharged or accumulating in a mass at the apex of the beak, 21-37 (x=32) x 7-15 (x=11) µm. |
|
| Sheath: |
Present/Absent. When present, apical appendages tightly coiled in ascus, unfurling to extremely long, fine, sticky appendages. |
|
| Appendage: |
|
|
| Culture: |
Colonies on peptone, yeast, glucose, 10% seawater agar agar floccose, white, becoming grey brown with age. |
| Anamorph: |

| Habitat: |
lentic, lotic, intertidal, marine |
| Distribution: |
Belize, Canada (Manitoba), China, USA (AR, FL, IL, LA, MD, MN, NH), Seychelles, Sri Lanka, Thailand. |

| Comments: |
This fungus was originally described from an estuary. It has been reported from marine, brackish and freshwater habitats. Freshwater collections appear to be very similar in morphology to those presented in the protoloque. |
