Fig. 4
Etymology.
variispora (Lat.) refers to the species having an uneven size of sporangiospores.
Holotype.
HMAS 352891.
Colonies on PDA at 25 ° C for 4 days, reaching 90 mm in diameter, more than 15 mm high, flat, granulate, initially white, soon becoming pale mouse-grey, irregular at margin. Hyphae aseptate at first, septate with age, hyaline, 4.5–11.5 μm in diameter. Rhizoids absent. Stolons absent. Long sporangiophores arising directly from substrate mycelia, transitorily curved, monopodially branched, with large terminal sporangia, erect, bent or curved. Sporangia globose, hyaline to brownish, wall rough with spines, deliquescent, rough, multi-spored, with more than 20 sporangiospores per sporangium, 30.5–60.0 μm in diameter. Short sporangiophores simple or sympodial, ending with a multi-spored. Multi-spored sporangiola subglobose to globose, with numerous spines, hyaline, containing 5–10 sporangiospores, persistent-walled, 14.5–26.0 μm in diameter. Apophyses absent. Collars absent. Columellae hemispherical, subglobose to globose, hyaline, 21.0–32.5 × 20.0–33.0 μm in long sporangiophores, conical and hemispherical, hyaline, 14.5–18.5 × 14.0–18.0 μm in short sporangiophores. Sporangiospores subglobose to globose, hyaline, with droplets, 5.0–16.0 μm in diameter. Azygosporangia absent. Chlamydospores absent. Zygospores absent.
