概述

子囊菌和担子菌子实体上产生有性孢子的结构.子囊菌的子实层是由子囊和侧丝(隔丝)组成的,它们整齐地排列成一层.子囊内核配后立即进行减数分裂,多数情况下4个 单倍体的核又各自进行1次有丝分裂,所以多数种类的子囊中产生8个子囊孢子.侧丝主要是由营养菌丝形成的.担子菌的子实层是由担子和侧丝组成的,有些伞菌种类还有各种大型细胞,即隔胞(囊状体),担子、侧丝和隔胞整齐地排列为一层栅栏状.担子中核配后,立即行减数分裂,多数种类的每个担子都产生4个外生的 担孢子.Ascomycetes and basidiomycetes produce sexual spores on the fruiting body structure. Ascomycetes hymenium is ascus and side wire (every other wire) formed, they neatly arranged in a layer. Ascus immediately after the kernel with subtrahend division, in most cases four haploid nuclear has carried out a time each mitosis, so the majority of types of ascus produced eight ascospores. side wire is mainly formed by the nutritional mycelium. smut hymenium is the composition of the burden and side wire, and some mushrooms there are a variety of large cell types, namely, every other cell (cystic body), burden, side wire and cellular compartment neatly arranged as a layer of palisade-like. the burden of nuclear distribution immediately after the OK meiosis, most of the burden of both types of produce each of the four exogenous basidiospores.
