Surface ornamentation of ascospores inEupenicillium species
The ascospores of 21 species ofEupenicillium were examined for surface ornamentation by means of the scanning electron microscope. Two groups of species could be distinguished: one with, and another without distinct equatorial ridges. The former group was further subdivided into four types according to wall ornamentation: reticulate, ribbed, spinulose, and smooth.Surface ornamentation details may come to range among the most important features to distinguish species that are hardly discernible otherwise.
Studies on the genus Eupenicillium Ludwig I. Taxonomy and nomenclature of Penicillia in relation to their sclerotioid ascocarpic states
The ascocarpic genus Eupenicillium Ludwig has been re-instated and reviewed taxonomically. It accommodates the perfect states of species characterized by pseudoparenchymatic or sclerotioid cleistothecia. The imperfect states belong to Penicillium Link ex Fries. Descriptions and synonomy of the genus and its type species E. crustaceum are presented. The generic name Eupenicillium has priority over the generic name Carpenteles Langeron. Penicillium kewense is reduced to the synonomy of E. crustaceum. The fungus misidentified by Shear as C. asperum is redescribed as E. shearii sp. nov. Species which had not previously been assigned to Eupenicillium are here so assigned.
Surface characteristics of Aspergillus conidia.
SUMMARYThe surface structures of conidia from 10 species of Aspergillus were studied and compared using freeze-etching procedures. The conidia of all species were shown to have characteristic “rodl...
