A natural mutant of Ascobolus michaudii (Ascomycotina, pezizales)
Wild strains of Ascobolus michaudii produce 8-spored asci and uninucleate ascospores with thick longitudinal anastomosing lines in the exosporium. A natural mutant in heterozygous condition with ascospores showing a thin verrucosely ornated exosporium, was isolated. The exosporium types segregated i...
