Fungalpedia - Note 540, Bulbilla   Bulbilla Diederich, Flakus & Etayo Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Lichenicolous fungi. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1  Classification: Incertae sedis, Cantharellales, Incertae sedis, Agaricomycetes, Agaricomycotina, Basidiomycota, Fungi. Diederich et al. (2014) introduced Bulbilla in Cantharellales to accommodate Bulbilla applanata based on ITS sequence data and ultrastructural analyses with the type species B. applanata. Bulbilla is a monotypic genus that is characterized by relatively large, lichenicolous, greyish yellow to greyish orange, basally constricted, internally adherent polyhedral cells, beige, translucent, applanate bulbils, without clamps (Diederich et al. 2014). This genus was placed in a new genus because it differs morphologically from all other bulbil-forming genera of Cantharellales (Diederich et al. 2014). To date, this genus has accommodated one species, Bulbilla applanate (type species), collected from Bolivia, and no [...]

Fungalpedia - Note 505, Burgellopsis   Burgellopsis Diederich & Lawrey Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Lichenicolous fungi. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1  Classification: Hydnaceae, Cantharellales, Incertae sedis, Agaricomycetes, Agaricomycotina, Basidiomycota, Fungi. Based on LSU sequence and ultrastructural analyses, Diederich et al. (2014) introduced Burgellopsis as a monotypic genus within Hydnaceae, Cantharellales in Agaricomycetes with the type species Burgellopsis nivea. Burgellopsis is characterized by white, superficial, roundish to irregular bulbils 100–220 mm in diam., roundish to polyhedral cells internally of indistinctly catenate, clamps absent (Diederich et al. 2014). In terms of morphology, Burgellopsis can be distinguished from Burgella by Bulbils being completely white, and no yellowish lipid droplets can be seen under a microscope, translucent. In phylogenetic analysis, the new gene Burgellopsis is sister to Burgella clade, so it was introduced [...]

Fungalpedia - Note 483, Bussabanomyces   Bussabanomyces Klaubauf, M.-H. Lebrun & Crous Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Ascomata. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1           Classification: Magnaporthaceae, Magnaporthales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi. Bussabanomyces was named after its collection (Bussaban) from Chiang Mai, Thailand (Klaubauf et al. 2014). This genus belongs to the family Magnoporthaceae and resembles Pyricularia; however, it is different because its conidiophores are usually unbranched, macronematous, and have special cylindrical and denticulate conidiogenous cells that form pale brown conidia with 4–5 septations (Bussaban et al. 2003, Klaubauf et al. 2014). Bussabanomyces longisporus is the only known species in this genus. Formerly named Pyricularia longispora, this genus is an endophyte that was discovered in the leaves of Amomum siamense (Bussaban et al. 2003). The families [...]

Fungalpedia - Note 367, Butyriboletus   Butyriboletus D. Arora and J. L. Frank Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Macrofungi. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1   Classification: Boletaceae, Boletales, Agaricomycetidae, Agaricomycetes, Agaricomycotina, Basidiomycota, Fungi  Butyriboletus was erected by Arora et al. (2014), typified with Butyriboletus appendiculatus and accommodated in Boletaceae. This genus  contains 29 ectomycorrhizal species found in Asia, Europe, North America, and North Africa (Zhao et al. 2015, Wang et al. 2022). However, Butyriboletus was previously classified as a section Appendiculati within the large genus Boletus. It was bestowed with the common name "butter boletes" because of the similarity in color between their stalk, flesh, and pores and that of butter (Arora et al. 2014). Butyriboletus is characterized by red or brown caps, yellow pores, and stipes, which turn blue when cut or bruised in many species. Additionally, Butyriboletus features olive-brown [...]

Fungalpedia – Note 541, Byssotrema   Byssotrema M. Cáceres, Aptroot & Lücking  Citation when using this data: Tibpromma et al. 2024 (in prep.) – Fungalpedia, Lichenicolous fungi. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1           Classification: Graphidaceae, Ostropales, Ostropomycetidae, Lecanoromycetes, Pezizomycotina, Ascomycota, Fungi. Byssotrema was introduced by Cáceres (2014) within Graphidaceae, Ostropales in Lecanoromycetes with the type species Byssotrema mirabile. This genus differs from Glaucotrema by its extremely uncommon ascoma morphology: the widely open ascomata are more robust and have a largely carbonized excipulum (Rivas Plata et al. 2012, Caceres et al. 2014). Morphological characteristics of Byssotrema having corticolous thallus, epiperidermal, thick, continuous; surface smooth, greenish grey; prothallus absent, cylindrical to angular ascomata, prominent to sessile, with sloping thalline margin; disc slightly exposed, light brown to pale white, pruinose; margin is distinct, complete, with a [...]

Fungalpedia – Note 159 Callimothallus  (Fossil Fungi)   Callimothallus Dilcher ex Janson. & L.V. Hills. Citation when using this data: Saxena RK & Hyde KD. 2024 (in prep) – Fungalpedia, Fossil Fungi.  Index Fungorum, Facesoffungi, MycoBank ,GenBank, Fig. 1 Classification: Microthyriaceae, Microthyriales, Fossil Ascomycota, Fungi Callimothallus was proposed by Dilcher (1965) from the Early Eocene (56–48 mya) sediments of western Tennessee, USA, with the following diagnosis: “No free hyphae. Stroma round, radiate, astomate, no central dehiscence, individual cells may possess single pore. Spores undetermined”. According to Dilcher (1965), Sapindus sp. leaves host this fungus, most frequently on the upper surface and occasionally on the lower surface. Since Dilcher (1965) did not designate a holotype, Jansonius & Hills (1976) selected a lectotype from the syntypes (all resulting from a single collection). Callimothallus lacks any central dehiscence and is characterized by numerous pores. It is the only [...]

Fungalpedia – Note 405, Callome   Callome Otálora & Wedin Citation when using this data: Tibpromma et al. (in prep.) – Fungalpedia, Liu et al., lichenicolous fungi, Mycosphere. Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. X          Classification: Collemataceae, Peltigerales, Lecanoromycetidae, Lecanoromycetes, Pezizomycotina, Ascomycota, Fungi. Based on the morphology and analyses of multigene phylogeny (LSU, SSU, MCM7, and TUB2), Otálora et al. (2014) introduced Callome to accommodate the type species Callome  multipartita as a revision of Collema multipartitum. Callome was isolated from lichen, which restricted to Europe, Northern Africa and North America (Otálora et al. 2014). Currently, only one species was accepted in this genus only with the sexual morph. Callome is characterized by foliose, dark olive green to black thallus with smooth, irregular, deeply, and repeatedly branched lobes, 8-spored asci, and linear oblong, straight, or curved spores with transverse septate (Otálora et al. 2014). Callome is phylogenetically [...]

Fungalpedia - Note 131 Calonectria   Calonectria De Not. Citation when using this entry: Aumentado et al. in prep – Fungalpedia, plant pathogens. Mycosphere.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig *. Ascomycota, Pezizomycotina, Sordariomycetes, Hypocreomycetidae, Hypocreales, Nectriaceae  Calonectria was identified based on C. daldiniana (De notaris 1867). Species within this genus were previously known as Cylindrocladium for many years. However, Rossman et al. (2013) favored the use of the name Calonectria over Cylindrocladium, following its conservation by Hawksworth (2011) and  McNeill et al. (2012). Most isolates were distinguished using morphological characteristics, such as macroconidial dimensions, septation, and vesicle shape, which are the mainly reliable traits for identifying Calonectria species (Li et al. 2017, Crous 2002, Schoch et al. 2000). For sexual morph identification, perithecial color, ascospore number, septation, and dimensions were also considered important (Lombard et al. 2010). However, due to the morphological similarity of [...]

Fungalpedia - Note 127 Calophoma   Calophoma Qian Chen & L. Cai Citation when using this entry: Aumentado et al. in prep – Fungalpedia, plant pathogens. Mycosphere.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig *. Ascomycota, Pezizomycotina, Dothideomycetes, Pleosporomycetidae, Pleosporales, Didymellaceae Calophoma was established by Chen et al. (2015) with Calophoma clematidina as its type species. Species belonging to this genus are characterized by pycnidial conidiomata which can be subglobose to irregular, and they may be found on the agar surface or immersed. These conidiomata can occur as solitary entities or may be confluent. Conidiomata are ostiolate, but in older cultures, they may have an elongated neck. Micropycnidia are also present. The pycnidial wall is pseudoparenchymatous and consists of 2–6 layers, with the outer wall being pigmented. The conidiogenous cells are phialidic, hyaline, smooth, and vary in shape from globose to flask-shaped, ampulliform, [...]

Fungalpedia – Note 295, Calvolachnella   Calvolachnella Marinc., T.A. Duong & M.J. Wingf Citation when using this entry: Perera et al. 2024 (in prep) – Fungalpedia, genera described in 2016.  Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1 Classification: Incertae sedis, Chaetosphaeriales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi Hernandez-Restrepo et al. (2016) established the monotypic genus Calvolachnella to accommodate asexual taxon C. guaviyunis found on the bark of Myrcianthes pungens. In the phylogenetic analysis of combined ITS and LSU sequence data P. guaviyuensis formed an independent lineage apart from other genera in Chaetosphaeriales. However, the genus has not been assigned to a family and left in Chaetosphaeriales, Incertae sedis (Hernandez-Restrepo et al. 2016). Calvolachnella is characterized by scattered, acervular, cupulate conidiomata with a broadly attached base to the substrate without setae. Conidiophores are arising from the concavity of the conidiomata, pale [...]
