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 [...]

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 [...]

Fungalpedia – Note 191 Didymoporisporonites (Fossil Fungi)   Didymoporisporonites Sheffy & Dilcher emend. Kalgutkar & Jansonius  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. Sheffy & Dilcher (1971) instituted Didymoporisporonites from the Claiborne Formation (Middle Eocene, 47–38 mya) of Puryear clay pit, Tennessee, Henry County, USA. According to the original diagnosis, Didymoporisporonites includes dicellate, uniseptate spores with a pore at the apex of one cell and psilate to punctate and variably sculptures the spore wall. Kalgutkar & Jansonius (2000) emended the generic diagnosis to restrict it to include dicellate spores with dissimilar cells (with smaller cell porate). The dicellate conidia are generally small to medium-sized, having thinner-walled proximal cells and smaller than the distal one and with a distinct pore or [...]

The genus includes two-celled, uniseriate, elliptical ascospores with uneven margins. The upper cell is prominent, and the spore wall is dark brown, thick, and sculptured with longitudinal ribs. The smaller lower cell is hyaline, appendage-like and with a faint rib sculpture. According to Jain & Gupta (1970), the single-celled ascospores of the extant genus Neurospora are similar to the two-celled fossil ascospore of Diploneurospora. Only one species is listed in [...]

Fungalpedia – Note 209, Diporicellaesporites (Fossil Fungi)   Diporicellaesporites Elsik. Citation when using this data: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Incertae sedis, Phragmosporae, Fossil Fungi. The fossil genus Diporicellaesporites was described by Elsik (1968) from the Rockdale lignite (Palaeocene, 66–56 mya) located 11 km southwest of Rockdale, Milam County, Texas, U.S.A. Diporicellaesporites includes elongated, disparate, and multicelled fungal or algal spores with one pore at each end of the spore. The shape and ornamentation are variable, except for being never coiled. Two or more septa were present (Elsik 1968). The fossilized species Diporicellaesporites taeniolelloides was described by Kalgutkar (1997). It is distinguished by its taeniolella-like, interconnected, and uniquely rough-walled conidia, which could not be studied; hence, its identification and affinities are still unknown (Heuchert et al.
