印度錫金紅菇科（Russulaceae）乳菇屬Plinthogalus亞屬的新種和Lactifluus屬Gerardii亞屬的新記錄種

New Species of Lactarius Subg. Plinthogalus and New Records of Lactifluus Subg. Gerardii (Russulaceae) from Sikkim, India

印度大陸的乳菇屬Plinthogalus(s.l.)亞屬共由13個分類群所組成。本文提出並描述乳菇屬Plinthogalus亞屬的二個新分類群：Lactarius crenulatus和L. croceigalus。有關於Lactifluus屬Gerardii亞屬，本文提出印度真菌誌的新記錄種Lactifluus leae，同時對該新記錄種和先前已報導過的L. ochrogalactus進行詳細地觀察，描述他們的巨觀和微觀形態，並提供手繪圖及照片作為佐證。更進一步將這些物種與亞洲地區相近分類群作比較和討論。

Lactarius subg. Plinthogalus (s.l.) was represented by thirteen taxa from the Indian subcontinent. In this paper, two taxa: Lactarius crenulatus, L. croceigalus are proposed and described as new species in Lactarius subg. Plinthogalus. From Lactifluus subg. Gerardii, two species, Lactifluus leae (new record for the Indian mycoflora) and L. ochrogalactus (reported earlier) are described for the first time with their macro- and micro-morphological details supported by illustrations. Comparisons with allied Asian taxa are also discussed.
