Assessment Notes

Taxonomic notes

Colony initially white, becoming pale grayish after 4 days in MEA at 25ºC. Reverse cream. Rhizoids abundant, long and short, simple or slightly branched. Stolons present, coenocytic, some showing septa near the sporophore origin. Sporophores short and long, erect or recumbent, arising from stolons or directly from aerial hyphae, hyaline, smooth-walled; some containing one or more septa below the sporangium or near the basis. Main sporophore axes simple or branched, usually equal in width throughout, some enlarging in the apical direction and ending in a vesicle (3.5–)5–10(–14) μm diam.; swelling below the vesicle present. Primary branches simple, in pairs,pseudo-verticillate (≤4). Short and long branches in the same sporophore common, repeatedly (≤6×) branching, some arising close to the vesicles and growing parallel to the main sporophores ≤500 × 7.5 μm, erect or slightly curved and terminating in a vesicle. Vesicles of the main sporophores light gray, mostly clavate, commonly irregular, angular, or flattened at the apex, rarely globose or subglobose, 17–47.5 × 20–37.5 μm. Lateral vesicles with same shape as the main vesicles, (2.5–)7.5–35 × (2.5)5.5–20(–25) μm. Sporangiola globose, light yellow with greenish yellow content and echinulate, (6.5–)10–20(–23) μm diam. Sporangiospores hyaline, echinulate- walled, usually remaining within the sporangiola. Chlamydospores absent.  Zygosporangia not observed.
