Three new species in the genus Tulasnella isolated from orchid mycorrhiza of Spiranthes sinensis var. amoena (Orchidaceae)

Mycoscience, 2019
Abstract We isolated Tulasnella spp. from Spiranthes sinensis var. amoena, a Japanese native winter green terrestrial orchid collected in Tsukuba City, Ibaraki Pref., Japan. These isolates were classified into four morphotypes according to morphological characters, i.e., shape of monilioid cells and branch type of monilioid cell chains, while they ...

Cryptic species revealed by molecular phylogenetic analysis of sequences obtained from basidiomata of Tulasnella

Mycologia, 2014
Delimitation of species and the search for a proper threshold for defining phylogenetic species in fungi are under discussion. In this study, morphological and molecular data are correlated to delimit species of Tulasnella, the most important mycobionts of Orchidaceae, which suffer from poor taxonomy.

Ultrastructure of Septa in Hyphae and Basidia ofTulasnella

Mycologia, 1976
In Tulasnella sp. there is a primary septum at the base of the basidium, and an adventitious septum, which differs in ultrastructure and development, at the base of the protosterigma.

A TULASNELLA PARASITIC ON AMOEBA TERRICOLA

American Journal of Botany, 1969
A microfungus attacking Amoeba terricola through germination of an adhering basidiospore is newly described as Tulasnella zooctonia. After intruding a branched haustorium into the animal, the spore extends one to three divergent procumbent hyphae externally, which at intervals give rise to obovoid hypobasidia.

Allantoid-spored Tulasnella species from Devon

Mycological Research, 1993
Tulasnella permacra, T. saveloides, and T. tomaculum are described as new. T. danica is described and recorded as new to Britain. T. allantospora is redescribed with reference to the holotype. Extra-limital species are briefly noted and a key is provided to accepted taxa.

A rare temperate terrestrial orchid selects similar Tulasnella taxa in ex situ and in situ environments

Plant Ecology, 2017
Mycorrhizal symbiosis in orchids is unique in that fungal presence is considered a requirement for germination as well as for further development. Additionally, orchid fungal associations can exhibit high specificity in nature. Yet, an important ecological question remains unanswered: ‘With which orchid mycorrhizal fungi (OMF) do un-inoculated orchid ...

A Cytological Study of Tulasnella

Botanical Gazette, 1932
1. Following karyogamy and the two meiotic divisions, the probasidium of Tulasnella produces from its summit commonly four inflated epibasidia; into these migrate the nuclei and protoplasm of the basal cell; when the latter has been exhausted the epibasidia are separated from it by septa across their bases. In T. violea, T.

Patterns of ballistospore germination in Tilletiopsis, Auricularia and Tulasnella

Transactions of the British Mycological Society, 1984
In Tilletiopsis washingtonensis ballistospore germination on malt agar results in a yeast-type phase before the mycelial condition develops a few days later. However, ballistospores germinating close to an established colony give rise directly to the mycelial state. In Auricularia auricula-judae and A.
