本文報導了我國齒耳屬(Stecherinum Gray)兩個新記錄種,集刺齒耳菌S. aggreatum Hjortstam & Spooner和圓孢齒耳菌S. hydneum (Rick) Maas Geest.。前者採集自湖北神農架自然保護區的樺樹倒木上,其主要特徵為菌肉菌絲單系,菌刺中骨架菌絲極少,該種與S. queletii (Bourdot & Galzin) Hallenb. & Hjortstam和S. albofibrillosum (Hjortstam & Ryvarden) Hallenb. & Hjortstam相近,但孢子較小。S. hydneum發現於湖北後河保護區的闊葉樹腐木上,此種宏觀形態與S. ochraceum (Pers.: Fr.) Gray極為相似,但孢子為近圓形。根據所採集的材料對這兩種真菌進行了詳細描述。
Two lignicolous fungi, ”Steccherinum aggregatum” and ”S. hydneum”, are newly recorded from China. The former species is similar to ”S. queletii” and ”S. albofibrillosum”, but it is distinguished by having smaller and more ellipsoid basidiospores. ”S. hydneum” is easily confused with resupinate specimens of ”S. ochraceum”, but spores of ”S. hydneum” are subglobose. An illustrated description of the two species is given based on material collected from Hubei Province, Central China.
