Taxonomy Of The Allium Tribracteatum (Alliaceae) Complex, William R. Mortola, Dale W. Mcneal
Aliso: A Journal of Systematic and Floristic Botany
Allium tribracteatum and related species present a confusing array in California. Previous attempts at classification have been largely unsuccessful and keys that are available are unworkable. Herbarium and field studies were initiated to ascertain if previously overlooked characteristics could be found that would elucidate relationships within the group. Members of the complex were examined morphologically and cytologically. Based on these investigations four of the seven previously described taxa are considered valid: A. cratericola, A. obtusum, A. tribracteatum, and A. yosemitense. Allium tribracteatum is redefined and A. obtusum is divided into two varieties. Allium obtusum var. conspicuum …

Morphology And Relationships Of A New Species Of Microsomyces (Ascomycetes: Laboulbeniales) From Illinois, Richard K. Benjamin

Microsomyces telephani, a new species of Laboulbeniaceae, is described from collections found on Telephanus velox (Coleoptera: Cucujidae) from Illinois. Features of development and maturity of the new species are illustrated with photographs and line drawings. Microsomyces telephani differs from the type and previously only known species of the genus, M. psammoechi, in its larger, more highly corticated receptacle, which bears secondary appendages, and in its larger primary appendage, which typically bears several antheridial phialides. Among known genera of Laboulbeniales, Microsomyces is thought to be most closely related to Cucujomyces.
