Stirps Haematocephalus
Singer (1976: 208) included M. haematocephalus and all its varieties, plus M. pallescens and M. panerythrus Singer in this group. In this paper, stirps Haematocephalus is monophylectic in haemat_cp1, now represented by the M. haematocephalus complex with pantropical distribution (Fig. 1). Even though similar to M. haematocephalus in the pileus color, both M. pallescens and M. panerythrus seem rather morphologically closer to M. pulcherripes (ser. Pulcherripes) by the shorter basidiospores.
