Fungalpedia – Note 199, Dendromyceliates (Fossil Fungi)   Dendromyceliates K.P. Jain & R.K. Kar. Citation when using this data: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1. Classification: Mycelia sterilia, Fossil Fungi.  Jain & Kar (1979) instituted the monotypic genus Dendromyceliates from the Miocene sediments of Chanakkodi, Quilon District, Kerala Coast, South India. The original diagnosis of Dendromyceliates is as follows: “Hyphae thick-walled, septate, cylindrical, base swollen, hyphae length divided into several cells by septa, cells with or without pores, generally uniporate. The tip of hyphae dichotomously branched 3-4 times, acutely pointed.” Dendromyceliates is conspicuous by the presence of dichotomously branched tips of the hyphae. The basal part of the hyphae shows some disc-like structures, which perhaps point out that the hyphae were attached to some other organ – probably [...]

Fungalpedia - Note 227, Diamantinia   Diamantinia A.N. Mill., Læssøe & Huhndorf. Citation when using this entry: Doilom et al. 2024 (in prep) – Fungalpedia,  Xylariomycetidae.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Xylariaceae, Xylariales, Xylariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi Diamantinia was established based on the morphology by Miller et al. (2003), with D. citrina as the type species which was collected from decaying decorticated wood and corticated branches on the ground in dry deciduous shrubby vegetation in Bahia, Brazil. This monotypic genus is characterized by black, superficial, turbinate stromata, surface minutely roughened, filiform paraphyses, 8-spored, cylindrical asci, amyloid, and apical ring shallow with flaring margins. Ascospores are broadly fusiform, initially hyaline, one-celled, and becoming two-celled by the formation of a transverse septum; upper cell consisting of a swollen, brown head with a narrow, longitudinal germ slit; lower cell consisting of a [...]

Fungalpedia – Note 274, Diatrypasimilis   Diatrypasimilis Jian L. Zhou & Kohlm. Citation when using this entry: Perera et al. 2024 (in prep) – Fungalpedia, genera described in 2016. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Diatrypaceae, Xylariales, Xylariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi                         Chalkley et al. (2010) established the monotypic genus Diatrypasimilis with D. australiensis as the type, based on ITS, LSU and SSU markers. Diatrypasimilis australiensis was isolated from the dead intertidal roots of Rhizophora (Chalkley et al. 2010). However, the name D. australiensis was not valid because it was published with the MycoBank identifier MB 515026, which has been already issued for another name. Therefore, the name was effectively published by Suh (2016). The sexual morph of the genus is characterized by thick stroma [...]

Fungalpedia – Note 187 Dicellaesporites (Fossil Fungi)   Dicellaesporites Elsik. Citation when using this data: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Didymosporae, Fossil Fungi. The monotypic fossil genus Dicellaesporites was described by Elsik (1968) from the Paleocene sediments (66–56 mya) in a strip mine approximately 11 km southwest of Rockdale, Milam County, Texas, USA and was diagnosed as: Inaperturate, psilate fungal spores, with two cells, uniseptate, exhibiting variable shapes. Sheffy & Dilcher (1971) emended the diagnosis as follows: Inaperturate fungal spores or algal bodies with psilate to scabrate sculpture. Norris (1986) also emended the diagnosis to characterize dicellate, inaperturate, isopolar, equilateral fungal spores. Spore wall levigate to scabrate. Kalgutkar & Jansonius (2000) stated that dicellate aporate spores may be isopolar with equilaterally exactly similar cells, but [...]

Fungalpedia – Note 86 Dicephalospora   Dicephalospora Spooner Citation when using this entry: Luo et al., in prep – Fungalpedia, discomycetes III. Mycosphere. Index Fungorum, Facesoffungi; MycoBank, GenBank, Fig. 1 Dicephalospora is a genus of Halotthiaceae (Helotiales) reported by Spooner (1987) with D. calochroa as the type species. The genus comprises 18 species, of which 13 were reported from China and three from Thailand. The species occur on leaf petioles, rotten wood and twigs (Zhuang et al. 2016). Dicephalospora species are characterized by an erumpent or superficial, stipitate, yellow, orange, red to blackish apothecia. The ectal excipulum is composed of textura prismatica cells with refractive walls, and the medullary excipulum is composed of textura intricata cells. The species have filiform asci, J+ or J- in Melzer’s reagent, straight or slightly curved paraphyses at the apex, and hyaline, sub-ellipsoid [...]

Fungalpedia – Note 194, Dictyosporites (Fossil Fungi)   Dictyosporites Félix emend. Kalgutkar & Janson. Citation when using this data: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Dictyosporae, Fossil Fungi. The monotypic fossil genus, Dictyosporites was instituted by Félix (1894) from the Eocene sediments of Perekeschkul, near Baku, Azerbaijan, and provided the following diagnosis: “The so-called wall-shaped conidia become multicellular by repeated transverse and longitudinal divisions. In addition to large conidia, whose growth can probably be regarded as complete, uni- and bicellular conidia representing the initial developmental stages also occur. They are all of the brownish colouration. Their outlines are rather variable, depending on the conidium's position to the section's plane. Viewed from the top or bottom, they often appear spherical with flatly indented outlines; longitudinal [...]
