Asexual morph: saprobic, hyphae 2.5-5 µm in diameter, septate, superficial or immersed, light-brown. Conidiophores 25-42 µm long, 2.5-5 µm in diameter, cylindrical, zero- to four-septate, simple, acrogenous or laterally on hyphae, often remaining connected with detached conidia, sometimes obsolete, straight or curved, light brown. Conidiogenous cells monoblastic, integrated, terminal, determinate. Conidia acrogenous, solitary, regularly or irregularly helicoid, mostly 1 to 1.5 times contorted, rarely semi contorted, six- to twelve-septate, not or slightly constricted at the septa, umber to reddish-brown; cells increasing in diameter from base to apex, distinctly dissimilar; spirals 20-38.5 µm in diameter; terminal cell 9-15 µm high, 10-20 µm in diameter, subglobose to ellipsoidal, basally flattened; basal cells 5.5-10 µm high, 3-5 µm in diameter, cylindrical; central cells subglobose, obtusely conical or doliiform. Sexual morph: Undetermined (Description based on Kohlmeyer and Kohlmeyer (1979)).

NOTES: Matsusporium tropicale is a widely distributed species in tropical and subtropical mangroves. The fungus differs from other marine species that produce helicoids conidia by the repeated coiled nature of the conidia that are dark brown in colour, surrounded by a sheath when young and by producing 12-septate conidia with long stalk (Abdel-Wahab et al. 2010). Sequence data placed Cirrenalia tropicalis in the Lulworthiaceae (Abdel-Wahab et al. 2010) with the introduction of a new genus Matsusporium to accommodate it as it did not belong in the Cirrenalia clade. The genus is accepted as a member of the Luloworthiaceae (Luloworthiales) in the subclass Lulworthiomycetidae by Jones et al. (2015) and Maharachchikumbura et al. (2015).
