Planistroma A.W. Ramaley, Mycotaxon 42: 69 (1991).
Mycobank number: MB 25358; Index Fungorum number: IF 25358; Facesoffungi number: FoF 06264; 7 morphological species (Monkai et al. 2013), 6 species with molecular data.
Type species: Planistroma yuccigenum A.W. Ramaley, Mycotaxon 42: 69 (1991), MycoBank: MB 358836.
Notes: Planistroma was established by Ramaley (1991), and is similar to Kellermania in ascostromata characters, but Planistroma differs on account of its aseptate ascospores (Barr 1996). The asexual morphs of Planistroma resemble Kellermania except in having apically appendaged conidia in the latter genus (Ramaley 1995). Minnis et al. (2012) synonymized Planistroma under Kellermania based on molecular data support. However, we follow Monkai et al. (2013) who assigned Planistroma as a distinct genus based on both morphological and molecular data.
