Notes: The genus Umbelopsis, erected by Amos and Barnett (1966) to accommodate
U. versiformis (initially positioned within the Deuteromycetes Sacc.), comprises 17 species (Yip 1986; Meyer and Gams 2003; Sugiyama et al. 2003Mahoney et al. 2004Wang et al. 2014Wang et al. 2015Crous et al. 2017Wanasinghe et al. 2018). Members of Umbelopsis produce velutinous colonies and sporangia with colors ranging from ocher to red and pink, except
U. nana, which produces hyaline sporangia (Sugiyama et al. 2003). The morphological classification of Umbelopsis specimens is based mainly on colony color, branching pattern of the sporangiophores, pigment production capacity, the size and shape of sporangia, columellae and sporangiospores, as well as the types of chlamydospores formed (Sugiyama et al. 2003Wang et al. 2015). The delimitation of species of this genus has also been based on physiological and genetic criteria (Meyer and Gams 2003; Sugiyama et al. 2003Ogawa et al. 2011Wang et al. 2015Spatafora et al. 2016Crous et al. 2017Wanasinghe et al. 2018).

 

Type species: Umbelopsis versiformis Amos & H.L. Barnett, Mycologia 58(5): 807 (1966).

Other accepted species: Species Fungorum – search Umbelopsis.
