Albatrellus and the Hericiaceae Naturalis
Stalpers, J.A..
The genus Albatrellus has long been considered to occupy a rather isolated place in the Polyporaceae. Arguments suggesting a taxonomic position in the Hericiaceae are presented.

Auriculariopsis and the Schizophyllales Naturalis
Stalpers, J.A..
The cultural characters and the development of the basidiomes of Auriculariopsis ampla (Lév.) Maire are described and compared with those of Schizophyllum commune Fr.: Fr. It is concluded that Auriculariopsis is very close to Schizophyllum and that the existence of the order Schizophyllales is not justified.

Comparison of Zygospore ornamentation in intra- and interspecific matings in some related species of mucor and Backusella Naturalis
Stalpers, J.A.; Schipper, M.A.A..
Zygospores resulting from intraspecific matings of Mucor amphibiorum, M. inaequisporus, M. indicus, M. recurvus, M. variosporus, Backusella circina, and B. lamprospora are compared with azygospores (zygospores) formed in matings of Mucor amphibiorum strain CBS 764.74 and strains of the other species by means of scanning electron microscopy. In general zygospores in interspecific matings cease to develop at an earlier stage than those of intraspecific matings. No proof could be obtained for our hypothesis that M. amphibiorum strain CBS 764.74 merely initiated a process of azygospore formation.

Notes on Mycoacia—I Naturalis
Stalpers, J.A..
The genus Mycoacia Donk (1931) originally contained four species, viz. M. fuscoatra (Fr. ex Fr.) Donk (type), M. uda (Fr.) Donk, M. stenodon (Pers.) Donk, and M. setosa (Pers.) Donk. This last species, however, is the type species of Sarcodontia S. Schulzer 1866. Later (1952) Donk considered M. setosa as generically distinct. The monotypic genus Sarcodontia has globose to subglobose spores with thickened walls and is parasitic, while Mycoacia has ellipsoid to allantoid thin-walled spores and is saprophytic. When Mycoacia and Sarcodontia are considered as congeneric (e.g. Nikolajeva, 1961), Sarcodontia is the correct name for the genus. Mycoacia and Sarcodontia are both classified in the Corticiaceae (Donk, 1964; Parmasto, 1968); they are characterized by...

Some Oomycetes and Zygomycetes with asexual echinulate reproductive structures Naturalis
Plaats-Niterink, A.J. van der; Samson, R.A.; Stalpers, J.A.; Weijman, A.C.M..
Fungi producing ornamented asexual structures and belonging to the Oomycetes (Trachysphaera) or Zygomycetes (Azygozygum, Mortierella) are described. They were studied by light and scanning electron microscopy while also mating experiments and carbohydrate analyses were performed. Azygozygum chlamydosporum is closely related to Mortierella indohii and therefore Azygozygum is considered to be a synonym of Mortierella. Mortierella echinosphaera spec. nov. is also closely related, but no zygotes are known, only ornamented chlamydospores have been observed. Absence of glucuronic acid and fucose and a low glucosamine content in Trachysphaera fructigena show that it belongs to the Oomycetes.

Spore ornamentation and species concept in Syncephalastrum Naturalis
Schipper, M.A.A.; Stalpers, J.A..
Morphological studies and mating experiments indicate the synonomy of Syncephalastrum verruculosum and S. racemosum. The ornamentation of the sporangiospores is due to folds of the merosporangial wall. It is highly variable and cannot be used for species delimitation.

Various aspects of the mating system in Mucorales Naturalis
Schipper, M.A.A.; Stalpers, J.A..
Several aspects of the sexuality in Mucorales are discussed. It is stated that neither heterothallism nor homothallism are absolute conditions and that a continuum exists between zygospores and azygospores. Mating type switching as known in ascomycetous yeasts would explain several up to now inexplicable phenomena.

Zygospore ornamentation in the genera Mucor and Zygorhynchus Naturalis
Schipper, Maria A.A.; Samson, R.A.; Stalpers, J.A..
Zygospores of species of the genera Mucor and Zygorhynchus were studied by means of scanning electron microscopy. The types of ornamentation are described and compared with those of some species of other genera of the Mucorales. The possibility of grouping the species according to zygospore characters is discussed.
