Abstract:
Two new species in Lepiota sect. Ovisporae are described from tropical China. Lepiota angusticystidiata has a pileus with brownish yellow squamules covering a trichodermial palisade, ellipsoidal basidiospores, and narrowly clavate cheilocystidia; L. brunneosquamulosa has a tomentose, squamulose pileus with brownish yellow to yellowish brown concentric zones covering a trichodermial palisade, rarely with short elements, ellipsoidal or subcylindrical basidiospores with straight adaxial side, and no cheilocystidia. Phylogenetic relationships among species of sect. Ovisporae were inferred based on DNA sequences of the internal transcribed spacer region (ITS1-5.8S-ITS2 = ITS), the 5' end of the 28S gene (D1-D2-D3 variable domains), and partial sequences of the intergenic spacer (IGS1) of the nuc rDNA and the mitochondrial small ribosomal RNA gene (mtSSU), supporting the delineation of these new species.

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
