The basidioma is composed mainly of sterile tightly packed hyphae; in most species there is a distinct fertile layer, the hymenium, on the surface of the basidioma that bears the basidial hyphae which, after meiosis, give rise to the basidiospores.

担子果主要由紧密缠绕的不育菌丝组成，多数种类还有明显的可育层子实层，子实层位于担子果的表面，由菌丝形成担子，减数分裂后产生担孢子（参见 basidium

The development of anther and ovule followed the finish of the flower organ initiation. Pollen mother cells and well developed microsporagium wall occurred when the diameter of the bud reached about 3.0 mm, and the archesporial cell which played the role of megaspore mother cell formed in ovule when the diameter of the bud reached about 3.5 mm.

花药及胚珠的发育与花器官的形态发生之间有明显的连续性，当花蕾直径为3.0 mm左右时花粉母细胞及完整的花粉囊壁形成，直径达到3.5 mm左右时胚珠中出现孢原细胞的分化，它直接起大孢子母细胞的功能。

根据有效成分，它可以通过头皮表面，居住皮革头皮屑孢子形成，有效地过滤睾酮，防止有害的激素，帮助毛囊的血液循环。

Lack of spore surface pitting,type of spore septation (usually 0- or 1-septate),and presence of fluffy,white to grey aerial mycelium on proprietary PDA supported this conclusion.

不同之处在于，辽宁菌株在自制PDA培养基上形成贴在培养基表面的菌落———与类型B相似，分生孢子长度介于A型和B型之间或与后者相近。
