摘要

本文報導台灣產殼狀菌三新種，即台灣刺皮菌(Dentipellis taiwaniana)美麗筍殼菌(Peniophora formosana)和粒狀顯絲菌(Phanerochaete granulate)。Dentipellis taiwaniana與D. microspora皆具有小型孢子，然而後者的子實層表面有許多分支狀絲狀體 (dendrohyphidia)，前者並無此構造。此外，D. taiwaniana產於中國東北溫帶的針葉樹而D. taiwaniana發現於台灣亞熱帶低海拔地區的闊葉樹。本文並提供已知Dentipellis六種的檢索表。Peniophora subsalmonea與P. formosana的形態特徵最相似，然而前者是一熱帶種，發現於印度洋的聯合島；而P. formosana發現於台灣的溫帶高山區。其次，P. subsalmonea的燈籠狀囊狀體(lamprocystidia)較P. formosana者短且寬。再者，P. subsalmonea的黏質囊狀體(gloeocystidia)為明顯厚壁（除先端為薄壁），先端有時呈尖形；P. formosana的黏質囊狀體為略厚壁，先端鈍形。P. subsalmonea的擔孢子也較P. formosana者略小。Phanerochaete granulata主要識別特徵是具有顆粒狀子實層表面、無囊狀體以及小型的擔孢子。

This paper reports three new species of corticioid fungi collected from Taiwan. They are Dentipellis taiwaniana, Peniophora formosana, and Phanerochaete granulata. Dentipellis taiwaniana resembles D. microspora in sharing small basidiospores while the latter differs in having numerous dendrohyphidia in the hymenium. Further, D. microspora occurs on gymnosperms in the temperate region of NE China while D. taiwaniana was found on angiosperms in subtropical lowland Taiwan. A key to the six known species of Dentipellis is provided. Peniophora subsalmonea seems to be most closely allied to P. formosana, by resemblance of general morphological features. The former is a tropical species, recorded from Reunion Island in the Indian Ocean while the collection of P. formosana was made from the high mountain temperate belt of Taiwan. Moreover, the lamprocystidia of P. subsalmonea are shorter and wider than those of P. formosana, and the gloeocystidia of P. subsalmonea are distinctly thick-walled, except for the thinwalled apical parts, and sometimes pointed at apices. In contrast the gloeocystidia of P. formosana are slightly thick-walled and obtuse at apices. Moreover, the basidiospores of P. subsalmonea are smaller than those of P. formosana. Finally, Phanerochaete granulata is characterized by having a grandinioid hymenial surface, a lack of cystidia, and small basidiospores.
