This paper also applies game theory to set up game models for ante-accommodation and post-accommodation. In the information model for ante-accommodation, commercial banks expect the occurrence of separate game equivalence not the pooled game equivalence, for in pooled game equivalence, commercial banks may easily choose adverse selection to provide loans because of asymmetric information, while in the supervision model for post-accommodation, banks and enterprises hardly make pure strategic equivalence, that is, they can not achieve Pareto optimum in the same time, meanwhile, when the supervision model for post-accommodation achieve pooled strategic equivalence, we will make use of probabilities of enterprises not keeping their promises and probabilities of bank supervision as indexes for describing qualitatively the credit risk for enterprises and the credit risk for bank supervision.

There are no distinct differences between ancestral character state and descendant character state in some characters. 4. Only one outgroup can't give enough information to tell what the ancestor looks like. It make us not to understand how a lot of charactors evolved. 5. The matsutake group is polyphyletic. 6. The character coding is not precise enough. 7. Some characters are not homology. The result of molecular systematic study on the matstuake group shows the group is not monophyletic. The matsutake group is more closed to Tricholoma than Armillaria. ITS sequence of Catathelasma ventricosum is nearly identical to that of the matsutake group, although apparently they are very different from each other in morphological characters.

对松口蘑群通过形态学特征进行系统发育关系分析造成很大的干扰的原因有：松口蘑的种类大多形态特征比较简单，可提供进行分析的特征不多；某些性状在一些状态之间的反复转化，造成分析上的误差；在进化过程中某些性状无明显的祖征和衍征，在分析过程中很难确定进化极性；选择外群时应该用一个特定类群进行整体理解后，确定各个性状的极性，不要只用单种作为外群；松口蘑群是一个多系群；进行比较的性状不一定是同源的；数量性状编码过于粗放，反映不出真实的情况。
