Ontogenetic comparisons of arbuscular mycorrhizal fungi Scutellospora heterogama and Scutellospora pellucida: revision of taxonomic character concepts, species descriptions, and phylogenetic hypotheses

Canadian Journal of Botany, 1994
The taxonomic significance of morphological characters in fungi of Glomales (Zygomycetes) has been based solely on superficial resemblance. Ontogenetic comparisons among isolates of Scutellospora pellucida and Scutellospora heterogama were used to resolve discrete stages of differentiation in which characters were delimited and ordered hierarchically ...

Scutellospora hawaiiensis: A new species of arbuscular mycorrhizal fungus from Hawaii

Mycologia, 1995
Scutellospora hawaiiensis, a species common in coastal sand dunes of Hawaii, is described. The pale orange-brown to red-brown spores have six walls; an outermost unit wall (1.2-2.0 um thick) appressed to a laminated wall (0.8-2.2 um), a coriaceous wall (2.8- 4.8 um), a new type of wall (the "notching wall") (0.5- 1.6 um), whose broken edges consist of ...

Scutellospora tepuiensis sp. nov. from the highland tepuis of Venezuela

Mycotaxon, 2017
Examination of soil samples collected from the summit of Sororopán-tepui at La Gran Sabana, Venezuela, revealed an undescribed species of Scutellospora whose spores have an unusual and very complex ornamentation. The new species, named Scutellospora tepuiensis, is the fourth ornamented Scutellospora species described from La Gran Sabana and ...

Scutellospora Dipurpurescens, A New Species in the Endogonaceae from West Virginia

Mycologia, 1988
Scutellospora dipurpurescens, sp. nov. (Endogonaceae) was discovered in several unmanaged pastures and a partially reclaimed surface coal mine in West Virginia. Spores are yellow to greenish-yellow with four walls. An outer finely laminate wall and a second hyaline membranous wall form the outer wall group. The inner wall group consists of a semi-rigid

Detection of the arbuscular mycorrhizal fungus Scutellospora heterogama within roots using polyclonal antisera

Mycological Research, 1995
The antigenic properties of the arbuscular mycorrhizal Scutellospora heterogama (BEG 35) were studied to develop a serological method for detecting the fungus in roots. Three polyclonal antisera were raised against the combined soluble and particulate fraction of spores of S. heterogama (BEG 35) and used in serological tests.

Development of extraradical mycelium of Scutellospora reticulata under root-organ culture: spore production and function of auxiliary cells

Mycological Research, 2004
The development of the extraradical mycelium and auxiliary cells and spore production of Scutellospora reticulata in association with Ri T-DNA transformed carrot roots was followed under root-organ culture conditions. Extraradical mycelium development followed classical lag-exponential-plateau phases, with an additional late decline phase in number of ...

Scutellospora ArenicolaandGlomus Trimurales: Two New Species in the Endogonaceae

Mycologia, 1989
San Miguel Island is the westernmost member ofthe Channel Islands and is situated 42 km off the coast of southern California. This small is? land (37 km2) is transversed by three major sand dune fields (Johnson, 1980) that account for ca 15% ofthe habitable island surface. Examination of soil samples collected from around the roots of plants growing in

Germination shields in Scutellospora (Glomeromycota: Diversisporales, Gigasporaceae) from the 400 million-year-old Rhynie chert

Mycological Progress, 2006
Glomeromycotan spores from the Lower Devonian Rhynie chert provide the first evidence for germination shields in fossil fungi and demonstrate that this complex mode of germination was in place in some fungi at least 400 million years ago. Moreover, they represent the first direct marker relative to the precise systematic position of an Early Devonian ...

Ontogeny and phylogeny of a Scutellospora heterogama mutant, with implications for morphological recognition of species in Glomeromycota

Fungal Biology, 2010
A putative mutant of Scutellospora heterogama has been maintained for 19 pot culture generations over 15y. The mutant differed phenotypically from the wild-type parental lineage in characteristics of the spore wall: albino versus pigmented red-brown color, high plasticity in acidic mutants versus rigid and finely laminate, deep red-purple reaction ...
