项目摘要

Field surveys were conducted to reveal the taxonomy of freshwater species of Verrucariaceae in Yunnan, China where many possibly freshwater species of this family were reported. Collected specimens were examined in detail, taxonomic study was made, and the followings were recognized : Dermatocarpon (1 sp.), Endocarpon (1 sp.), Staurothele (3 spp.), Thelidium (4 spp.), and Verucaria (13 spp.). Species of the foliose and squamulose genera (Dermatocarpon and Endocarpon) were same with those found in Japan, but there are siginificant differences for crustose genera. The following new species were recognized: Staurothele honghensis H.Harada & Li S.Wang, Thelidium luchunense H.Harada & Li S.Wang, T.sinense H.Harada & Li S.Wang, T.yunnanum H.Harada & Li S.Wang, and 7 species of Verrucaria (in preparation). In addition, a field survey was conducted in northern Taiwan to reveal the identity of Staurothele fauriei de Lesd., which was described on the basis of a specimen collected by U.Faurie in northermost Taiwan. As the result, a freshwater species of Staurothele was found on riverside rocks, which is conspecific with Staurothele iwatsukii H.Harada originally described from Japan with some subtle morphological diffrences. It is possibly conspecific with Staurothele fauriei ; however, the type specimen of Staurothele fauriei, on the other hand, could not be located, thus the identity of this species is still unknown. Thus, it is best choice at present that the freshwater Staurothele be called Staurothele iwatsukii.

通过野外调查，初步探讨了云南疣孢科淡水种的分类学特征，并报道了该科的许多可能的淡水种。对采集的标本进行了详细的鉴定和分类研究，并鉴定出皮果虫属（Dermatocarpon，1 sp.）内果菌属（Endocarpon）1种，十字藻属（3种），球孢霉属（Thelidium）（4种），和Verucaria（13 spp.）。叶状属和鳞片属（皮果属和内果属）的种类与日本相同，但甲壳属的种类有显著差异。本文记述了新种：洪河角苔（StaurothelehonghensisH. Harada & LiS.Wang）、芦春苔（ThelidiumluchunenseH. Harada & LiS.Wang）、中华苔（T. sinenseH. Harada & LiS.Wang）、云南苔（T. yunnanumH.Harada & LiS.Wang）和疣孢属（Verrucaria）7种（准备中）。此外，在台湾北方进行了野外调查，以揭示福氏星介的身份，这是根据Faurie在台湾最北部采集的标本描述的。结果表明，在滨江岩石上发现了一种淡水的Staurothele，它与最初在日本描述的Staurothele iwatsukii H.Harada是同种的，但在形态上有一些细微的差异。它可能与Staurothele fauriei同种;然而，另一方面，Staurothele fauriei的模式标本无法找到，因此该物种的身份仍然未知。因此，将淡水十字水母类命名为岩崎十字水母是目前最好的选择。
