Saprobic on decaying plant. Asexual morph: Colonies on plant substrate effuse, scattered, white to pale brown. Mycelium partly immersed, composed of brown hyphae. Teleomorph: Unknown. Anamorph: Conidiophores macronematous, erect, straight, or flexuous, unbranched, septate, smooth, dark brown at the base becoming light brown towards the apex, cylindrical. Conidiogenous cells polyphialidic, integrated, terminal, pale brown, cylindrical; collarettes funnel-shaped. Conidia aggregated in slimy mass at the apex of the conidiophores, acrogenous, smooth, hyaline, septate, with guttulates, cylindrical, oblong, with an appendage at each end (Adaptred from Lin et al. 2019).
Geographical distribution: China, Japan, Malaysia, Peru and Thailand (Réblová et al. 2021).
Description and illustration: Lin et al. (2019).
Notes: In the phylogenetic study of hyaline-spored chaetosphaeriaceous fungi, Lin et al. (2019) found that Multiguttulispora sympodialis C.G. Lin & J.K. Liu phylogenetically formed a separate linkage within the family Chaetosphaeriaceae on the tree generated based on the combined LSU and ITS sequence data. Therefore, the newgenus Multiguttulispora was introduced to accommodate this distinct fungus. Morphologically this genus is characterized by absence of setae, macronematous conidiophores terminated in a polyphialidic conidiogenous cells with sympodial extension, and ellipsoidal to oblong to ellipsoidal-fusiform, hyaline, 3-septate and multiguttulate conidia with a basal hilum and a gently curved setula at each end. More recently Réblová et al. (2021) showed that in the phylogeny, the genus forms a monophyletic lineage containing two species, Codinaea dimorpha and C. triseptata. Furthermore, the comparison of morphological characters and DNA sequences revealed M. sympodialis conspecific with Codinaea dimorpha. Therefore, Codinaea dimorpha and C. triseptata were transferred to Multiguttulispora, and M. sympodialis was reduced to a synonymy of M. dimorpha. In our phylogenetic analysis, the three Multiguttulispora species, M. dimorpha, M. triseptata and an undescribed species are grouped together and form a well–supported distinct clade. This analysis further supports the generic delimitation of Multiguttulispora. In our study including several Multiguttulispora specimens from China, we observed the breaking-off of the collarettes from conidiogenous cells and carried away by the conidia, and this make the conidiogenous cells with a sympodial appearance without collarettes. This was also shown in their illustration of D. triseptata by Crous et al. (2015).
