. A handbook of cryptogamic botany. Cryptogams. BA S IDIOM YCE TES 391 promyceles from teleutospores. From the Tremellines another easy step leads us on to the Thelephoreae, and it may be borne in mind in this connec- tion that certain Tremellineae, as mentioned above, do not possess gelatinous membranes. The Thelephore^ (Corti- cium, Pers.) may be shortly described as recalling in point of simplicity of structure the teleutospore-layer of Uredineae, while they approach very closely the club-shaped Hymenomy- cetes such as the Clavariese, in which the hymenium is dis- posed on the outer surface of erect club shaped cylindrical and often much-branched com- pound sporophores. Through a series of intermediate forms, the completeness of which may be recognised from a systematic study of the group, we proceed to the more perfect types of Hymenomycetes which possess sporophores of more complex structure. In the higher forms of Hymenomycetes, the sporo- phore consists of a cap ox pikus borne on the summit of a stalk or stipe. The mycele com- monly vegetates in a soil rich in humus or on old wood or the like, and though usually of loose filamentous texture it is in Fig. 319.—Agaricus nteUeus L., in difFe- rent stages of development on branched • rhizomorph-strands. The upper portion of rhizomorph represents that formerly ; known as Rkizomorpha. fragilis Roth, while the lower strap-shaped portion is var. subcorticalis. (After Hartig.).
