Type species – Misturatosphaeria aurantiinotata Mugambi & Huhndorf, Stud. Mycol. 64: 108 (2009).

Notes – Misturatosphaeria was introduced to accommodate M. aurantonotata (type species), M. claviformis, M. cruciformis, M. kenyensis, M. minima, M. uniseptata, M. tennesseensis and M. uniseriata from decorticated woody branches. Thambugala et al. (2015b) re-analyzed Misturatosphaeria species using multi-gene phylogeny and included three species M. radicans (ATCC 42522 & SMH 4330), M. aurantonotata (GKM 1280 & GKM 1238) and Misturatosphaeria sp. (SMH 4737). Jaklitsch et al. (2016b) synonymized all Misturatosphaeria species under Teichospora and considered T. trabicola as type species. The morphological characters of M. aurantonotata differ from T. trabicola in having long pedicellate asci, brown to dark brown (initially hyaline), fusiform, 3-septate ascospores with a mucilaginous sheath when the spores are in young stage, whereas T. trabicola has brown and muriform, ellipsoid to clavate ascospores without a mucilaginous sheath (Jaklitsch et al. 2016b). According to the multi-gene phylogeny herein, Misturatosphaeria species nested separately from Teichospora species (Fig. 152). Therefore, we keep Misturatosphaeria as a separate genus in Teichosporaceae.

Figure 152 – Phylogram generated from maximum likelihood analysis (RAxML) of genera in Teichosporaceae based on ITS, LSU, and tef1 sequence data. Maximum likelihood bootstrap values equal or above 70 %, Bayesian posterior probabilities equal or above 0.90 (MLBS/PP) are given at the nodes. An original isolate number is noted after the species name. The tree is rooted to Hermatomyces tectonae (MFLUCC 14-1140) and H. thailandica (MFLUCC 14-1143). The ex-type strains are indicated in bold. Hyphen (-) represents support values below 70 % MLBS and 0.90 PP.
