Platystomum Trevis.

Notes: Cesati and De Notaris (1863) transferred and accommodatedSphaeria compressa Pers. in LophiostomaLophiostomataceae) based on immersed to slightly erumpentcomata with a cylindrical papilla. Lophiostoma compressumwas transferred to several different genera, but Zhang et al.2009, 2011) placed L. compressum in Lophiostoma based onphylogenetic placement. Platystomum was introduced byevisan (1877) and is typified by Platystomum compressum(Pers.) Trevis. Platystomum compressum is listed as asynonym of Lophiostoma compressum (Pers.) Ces. & DeNot. in Index Fungorum (2015). However, Mugambi andHuhndorf (2009) showed in their combined phylogeneticanalysis, a putatively named strains of P. c omp re s s um groupedwith Pseudotrichia guatopoensis Huhndorf and Xenolophiumguianense Huhndorf in a separate clade fromLophiostomataceae, which may correspond to the familyPlatystomaceae (Mugambi and Huhndorf 2009;Hydeetal.2013). However, in this phylogenetic analysis (Fig. 1) thestrain (MFLUCC 13-0343) from new collection ofP. c o mp re s s u m grouped in Lophiostomataceae with othernew species of Platystomum (MFLUCC 14-0925, 15-0632,15-0633) and the putatively named strains of L. compressum(KT 521, JCM 13125 and IFRD 2014), Lophiostomatriseptatum Peck (SMH 5287 and SMH 2591) andLophiostoma viridarium Cooke (IFRDCC 2090) in a samesubclade (A1). We observed and illustrated the specimensattached to KT 521, JCM 13125 strains and the strains ofL. triseptatum and L. viridarium in GenBank are named withoutattached voucher material. Therefore, it is impractical toconfirm their characters. Re-collection, epitypification or areference specimen (Ariyawansa et al. 2014b) with moleculardata are essential for the type species of L. viridarium andL. triseptatum to establish their placement in Platystomum. We accept Platystomum in Lophiostomataceae as a distinctgenus and introduce four new species in Platystomum basedon new collections and two strains (KT 521 and JCM 13125).
