Tricholoma may be a paraphyletic genus two. The collections identified as T. caligatum is a mixture. Some parts of them from France are members of T. matsutake, the other parts from North America are closed to T. bakamatsutake and T. fulvocastaneum. Tricholoma robustum and T. focale form a clade which is obviously a sister group of the stirp Subannulate. The stirp Caligata was defined as a group mainly on the basis of the predominant veil. But from the result of molecular systematic analysis, the presence of veil is not a stable character in the matsutake group. Species having symbiosis with conifers and broad leaf tree are all transformed from those whose host specificity is not strict. The phylogenetic tree based on ITS sequences resembled the tree of NJ algorithm based on cladistic coding. In the phylogenetic tree based on morphylogical characters, T. zangii and T. bakamatsutake form a clade, but it is the result of convergent evolution as suggested by molecular analyses. The distribution area of the matsutake group can be divided into six regions: middle and northern Europe region, Mediterranean region, Hengduan Mount.— Southeastern Tibet region, Northeastern China—Japan—Far-east Russia region, the Atlantic—North America region and the Rocky Mountain region. The abundance center of the matsutake group are Hengduan Mount.—Southeastern Tibet region and the Rocky Mountain region. Hengduan Mount.
松口蘑群的分子系统学研究得出的结果有：由于粗壮口蘑和羽衣口蘑明显和亚环族(Tricholoma，section subannulate)的种类是来自同一个谱系，和其它松口蘑群的种不具有最近共同祖先，因此松口蘑群是一个多系群；松口蘑群和口蘑属其他种类的亲缘关系比和蜜环菌属更接近；梭柄松苞菇和松口蘑群的差距明显小于油黄口蘑(T.flavovirens)和棕灰口蘑；口蘑属是一个多系群；鉴定为欧洲口蘑的标本明显不是一个单系群，其中一部分是松口蘑，另一部分和黄褐口蘑及傻松口蘑(T.bakamatsutake)比较接近；划分松口蘑群的标准是菌环的存在，但从分子系统学的结果来看，菌环的存在与否并非是一个很稳定的性状；和针叶树专性共生及和阔叶树专性共生均由寄主专化性不强的种类转化而来；在形态学系统发育树上青冈口蘑和傻松口蘑被聚为一个分枝，分子系统学的研究结果表明，这是趋同进化的结果；用支序方法编码作出的NJ树的结果更接近ITS序列的结果。

-
biotype：生物型
并不立即杀伤寄主植物的细胞和组织. 指病原物对寄生植物的一定科、属、种或品种的寄生选择性. 往往被区分为:变种(var.),专化型(f.sp.),生理小种(physiological race),菌系(strain)或株系,生物型(biotype)或致病型(pv.)
-
Entamoeba histolytica：痢疾阿米巴
⒊侵入机制得到加强 为增加进入宿主及组织的机会,侵入机制得到专化与加强,例如痢疾阿米巴(Entamoeba histolytica)具有穿透肠粘膜的蛋白质水解酶,而在共栖型的结肠阿米巴却没有发现这些酶.
-
fossilization：化石化
由泛指(generic)到专指(specific)的作用.但是,一定的语境,使得"其"的回指变得可有可无,或因汉语的省略定势与节律阻止回指说,直至不能说有.由有回指到可有可无,到不好说有,到没有回指的过程,就是"其"的化石化(fossilization)过程.
-
highly specialized：高度专化的
highly skewed distribution 高度偏斜分布 | highly specialized 高度专化的 | highly statistical significance 高度统计显著性
-
mechanistic：机械式
回顾组织结构的研究,Courtright等人提出组织结构除了机械式(mechanistic)的形式之外,还有有机式(organic)的结构. 机械式的结构是高度专精化、明确的部门界限、清楚的命令鍊,控制幅度相对狭窄,主要集权於少数高层管理者,并且有各种书面化的规章,
-
thinning：细线化
形态学(morhpology) 原本系研究动值物形态的生物学门,但在影像方面,则用来专指抽取出影像中特定成份的技术. 在影像处理中,如影像分割(Segmentation),边缘检测 (Edge detection),细线化 (Thinning),骨架抽出(Skeletionizing)皆可说是形态学上的手段之一.

Verticillium：轮枝孢属
主要由镰孢属(Fusarium)轮枝孢属(Verticillium)真菌和假单胞杆菌属(Pseudomonas)细菌分别引起的枯萎病、黄萎病和青枯病等的总称. 引起枯萎病的镰孢属真菌有较高的寄生专化性,如尖镰孢菌(Fusa-riumoxysporum)有70多个专化型分别侵染一定的寄主,
-
Virulence：毒性
致病性从其变异或分化来看,可分解为两大组分:毒性(Virulence)和侵袭力(aggressiveness). 毒性(也有人译作毒力)是指病原物克服寄主某一专化抗病性而能够侵染,使之感病的能力,是质量性状,它是专化于品种的,它只能克服某一定抗病基因,
-
termites：白蟻
脊椎动物和白蚁(termites)中一些抗菌肽的蛋白序列在正向选择下快速的进化,表明其可能与病原菌是协同进化的. 相反,作者研究发现7种果蝇中的抗真菌肽与抗细菌肽趋于高度保守,没有与病原菌协同进化,可能是由于果蝇种群缺乏专化性的真菌和细菌致病菌的原因.
-
pheromone：外激素;信息素
与神经中枢,也就是第3胸神经节联系.这些嗅毛可十分敏感地检测空气中存在而浓度很低的物质分子,这显然对昆虫的陆栖生活十分重要.因为动物的行为和个体发育往往受外激素(信息素)(pheromone)的激引,而外激素是高度专化的挥发性物质,
