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 [...]

Fungalpedia - Note 491, Diederichomyces    Diederichomyces Crous & Trakun. Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Lichenicolous fungi. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1  Classification: Phaeosphaeriaceae, Pleosporales, Pleosporomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi. De Gruyter et al. (2009, 2013) stated that all Phoma sensu stricto was placed on Didymellaceae. Lawrey et al. (2012) placed all lichenicolous Phoma species in the Phaeosphaeriaceae (Pleosporales). Trakunyingcharoen et al. (2014) introduced Diederichomyces to accommodate most of the lichenicolous Phoma on the basis of having dimorphic conidia, and orange crystals in culture and Diederichomyces recovered as polyphyletic clade in the LSU phylogeny. Ertz et al. (2015) synonymized Diederichomyces under Didymocyrtis along with Diederichia. Diederichomyces clustered together with lichenicolous Phoma species in the phylogenetic analysis, and the oldest name, Didymocyrtis, was further accepted.   Type species: Diederichomyces xanthomendozae (Diederich & Freebury) [...]

  Fungalpedia – Note 311, Dimorphiseta   Dimorphiseta L. Lombard & Crous Citation when using this entry: Perera et al. 2024 (in prep) – Fungalpedia, genera described in 2016.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Stachybotryaceae, Hypocreales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi             Lombard et al. (2016) introduced Dimorphiseta to accommodate single species that clustered sister to Smaragdiniseta in their phylogenetic analysis of cmdA, ITS, rpb2 and tub2 loci. Dimorphiseta is characterized by sporodochial conidiomata encircled by one or two types of setae that enclose an olivaceous green to dark green slimy mass of conidia. Sporodochia are stromatic, superficial, scattered to gregarious, cupulate and oval to elongate or irregular in outline. Stromas are well-developed, hyaline, and have a globulosa or angularis texture. Type I setae are hyaline, flexuous to circinate, thin, verrucose-walled, and tapered to an obtuse [...]

Fungalpedia - Note 551, Dinomyces    Dinomyces Karpov & Guillou Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Chytridiomycota. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1  Classification: Dinomycetaceae, Rhizophydiales, Incertae sedis, Rhizophydiomycetes, Chytridiomycotina, Chytridiomycota, Fungi. Dinomyces (Dinomycetaceae) was established by Lepelletier et al. (2014) as a monotypic genus with the type species Dinomyces arenysensis based on phylogenetic and morphological characteristics studies. This species is the first chytrid known to infect marine dinoflagellates, instead there are many chytrids infecting microalgae in freshwater (Gleason et al. 2011). Dinomyces is characterized by a parasitoid of marine dinoflagellates with a simple thallus with inoperculate, monocentric, epibiotic sporangium with endogenous development, apophysum, and branching rhizoidal axis (Lepelletier et al. 2014). Zoospores are distinguished by a central ribosomal aggregation that separates the nucleus from the microbody-lipid complex (MLC), which comprises a [...]

Kalgutkar et al. (1993) described the monotypic fossil genus, Diplodites, from the Deccan Intertrappean beds (Late Cretaceous, Maastrichtian, 72–66 mya) of Mohgaon Kalan, Chhindwara District, Madhya Pradesh, India. This genus is characterized by septate, branched, smooth, thick-walled, intercellular hyphae in the pericarp. It is thick-walled with pseudoparenchymatous tissue, generally ostiolate, and astomous when immersed, solitary or aggregated in small groups and with subicle or stroma. Stroma are typically dark brown or black, composed of thick-walled cells, uniloculate. Conidia are 1-septate or aseptate, both kinds occurring in the same pycnidium, light to dark [...]

Fungalpedia – Note 190, Diploneurospora (Fossil fungi)   Diploneurospora Jain & Gupta  Citation when using this data: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig.  1 Classification: Sordariales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Fossil Ascomycota, Fungi The monotypic fossil genus, Diploneurospora, was described by Jain & Gupta (1970) from the Early Miocene (23–16 mya) sediments of Padappakkara, Kollam District, Kerala, India. 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.

Fungalpedia – Note 231, Diporipollis (Fossil Fungi)   Diporipollis S.K. Dutta & S.C.D. Sah emend. Kalgutkar & Janson.  Citation when using this entry: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Phragmosporae, Fungi Imperfecti, Fossil Fungi The monotypic fossil genus Diporipollis was described by Dutta & Sah (1970) from the Cherra Formation (Early Eocene, 56–48 mya) of Umstew, South Shillong Plateau, Meghalaya, India. According to the original generic diagnosis, this fungus is small to medium-sized and diporate with more or less globular to sub-spheroidal amb. Pores are placed one over the other, circular in shape, and encircled by one or more thickened rims. Exine is thin with psilate to scabrate or finely granulate surface sculpture. Kalgutkar & Jansonius (2000) emended the generic diagnosis: “Small to medium-sized, tri- to [...]

Fungalpedia – Note 213, Diporisporites (Fossil Fungi)   Diporisporites Hammen 1954a. Citation when using this entry: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Amerosporae, Fossil Fungi Van der Hammen (1954a) instituted the genus Diporisporites from the Maastrichtian (72–66 mya) sediments of Eastern Cordilleras, Colombia, with the following short diagnosis: Fungal spores “with two small pores” (vide Jansonius & Hills 1976, card 810). Elsik (1968) provided an elaborate, emended generic diagnosis to include unicellate, diporate fungal spores with one pore on each opposite end of the spore. Pores may be modified, i.e., with atrium, annulus, or septum forming a pore chamber—shape and ornamentation variable. Type species: Diporisporites elongatus Hammen 1954a (designated by van der Hammen 1954b).     Figure 1 – Diporisporites elongatus Hammen. Scale bar = 10 μm. Redrawn from van der Hammen (1954a).

Fungalpedia - Note 452, Diromma   Diromma Ertz & Tehler Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Lichenicolous fungi. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1  Classification: Roccellaceae, Arthoniales, Arthoniomycetidae, Arthoniomycetes, Pezizomycotina, Ascomycota, Fungi. Diromma was introduced by Ertz et al. (2014) in Roccellaceae (Arthoniales, Arthoniomycetes) with the type species D. dirinellum, which is strikingly similar to Ocellomma picconianum (Ertz et al. 2014), but differs by the corticated thallus and the immersed to semi-immersed ascomata (Ertz et al. 2014). In phylogeny, Diromma formed an independent lineage within the Roccellaceae where it is related to the genera Dirina and Roccella. The sexual morph is characterized by circular ascomata, oblong to irregular in substrate, surface white pruinose, with a thin and corticated thalline margin level with the hymenial disc; hymenial disc usually widely exposed, but sometimes slit-like, [...]
