when observed under a lens, consists of free thecae spore sacs filled with spores and separated by little fibrils or paraphyses sterile filaments; in others, it presents a similar membrane. In substance, position, and form, it always corresponds to the pileus.
§. 6.
The Hymenium is further distinguished by its varied form.
1. In many, it is entirely smooth, or distinguished by no protuberances: as in Peziza, Helvella, Clavaria, etc.
2. Or it protrudes into lamellae gills and veins, for example in Agaricus and Merulius.
3. It is elongated into tubes, or is merely porous, as in Boletus and Poria.
4. In Hydnum, Odontia, etc., it is distinguished by teeth, awls, or spines.
5. It is papillose covered in small pimples in Thelephora, in which sometimes it also appears setose bristly.
§. 7.
The so-called seeds of fungi are observed only as frost or flour in fungi that are mostly open, and in Sarcocarpi fleshy fungi they are bare or are elastically propelled like a cloud. In others, they float in gelatin (latex) or mucilage; if they are present in great quantity (powder), they are generally found included within a closed peridium or capsule. In some, they are intertwined with a capillitium a network of sterile filaments or threads, and possess a globose or ovate shape. When considered individually, they are also called Spores or Sporules.
Vesicles seem to consist of consolidated spores.
§. 8.
Some species of fungi are covered by a certain membrane before evolution development, which is called an involucrum wrapper or veil.
