<ascospore> hyaline
the outer two layers are evanescent, rapidly degrading; OWL1 hyaline, 0.5-0.9 µm thick; OWL2 is hyaline to sub-hyaline, becoming creamy in lactic acid based mountants, evanescent (to semi-persistent), 0.9-3.2 µm thick, rapidly degrading and showing innumerous fissures beginning from the outer surface; OWL3 is hyaline to sub-hyaline, 0.9-1.5 µm thick, semi-persistent to persistent and is often the only OW layer that remains on the spores; OWL2 may stain bright yellow, OWL3 regularly stain bright to dark bright yellow in Melzer's reagent; Middle wall is hyaline, flexible, one to bi-layered, and in total 0.8-1.9 µm thick, second layer stains bright yellow in Melzer's reagent, Inner wall bi- to triple-layered, hyaline, and in total 1.9-3.4 µm thick, IWL1 is 0.5-0.7 µm thick and often difficult to observe as tightly adherent to IWL2, IWL2 is unite to finely laminate, 1.4-2.7 µm thick, IWL3 is very thin, and usually it is detectable only when it forms several folds, IW layers do not stain in Melzer's reagent
