Indurated ascus

locus: Iasc

locus_name: Indurated ascus

organism_type: B

chromosome_number: V

chromosome_side: R

link_group: VR

cultural_requirements: VR. (A.M. Srb, personal communication)Ascus wall hardens and darkens, so that the entire ascus resembles a giant ascospore. Pores are formed and striations appear. Asci are germinable. Mutant ascus phenotype is dominant with variable expression. Some asci are normal. Vegetative growth is weak (1008). Resembles the indurated ascus phenotype described in N. tetrasperma(285).
