“…Termitomyces are primarily divided into the following two subgenera based on the presence or absence of pseudorhiza, a plant root-like structure connected to the fungus comb (Frøslev et al 2003;Wei et al 2009;Tibuhwa 2012): Praetermitomyces, the member of which has a very small fruiting body and lacks pseudorhiza, and Eutermitomyces, members of which have large fruiting bodies and possess pseudorhiza.

Fungus‐growing termites (subfamily Macrotermitinae) cultivate the symbiotic basidiomycete fungus Termitomyces in their fungus comb to digest cellulosic materials and to supply nitrogen‐rich fungal diet. In Japan, the fungus‐growing termite Odontotermes formosanus is found on the Yaeyama Islands and Okinawa Island, Okinawa Prefecture. Odontotermes formosanus is thought to have been recently and artificially introduced to Okinawa Island as its distribution is discontinuous and restricted to small areas. Previous DNA analyses revealed that two types of Termitomyces, namely Termitomyces sp. Type A and Termitomyces sp. Type B, whose fruiting bodies correspond to Termitomyces microcarpus‐like pseudorhiza‐lacking small mushroom and Termitomyces intermedius, respectively, are cultivated by O. formosanus on the Yaeyama Islands. However, information about the Termitomyces types cultivated by O. formosanus on Okinawa Island is limited. To define the fungal types cultivated by O. formosanus on Okinawa Island, I developed a diagnostic polymerase chain reaction method using primer sets specific to the nuclear ribosomal DNA sequences consisting of the internal transcribed spacers (ITS1 and ITS2) and 5.8S rDNA of Termitomyces not using fungal mycelium, but using the termite gut metagenome including fungal DNA as a template. The results indicated that the same two Termitomyces types from Iriomote Island are cultivated by O. formosanus on Okinawa Island. The distribution pattern of Termitomyces types on Okinawa Island showed that Termitomyces sp. Type A is limited to the mountainous side of Sueyoshi Park, despite Termitomyces sp. Type B being widely distributed in the area in which O. formosanus is found. This finding implies that O. formosanus on Okinawa Island was recently introduced from Iriomote Island to Sueyoshi Park.

“…A phylogeny tree made from the concatenated genes of LSU and mtSSU suggests that Termitomyces specimen is closely related to T. bulborhizus from China [45,46]. ML analysis revealed that Termitomyces specimen is monophyletic with strong support (BS ¼ 100%; PP ¼ 1.0) and distinctive compared to T. bulborhizus from China.…”

“…Morphological features of T. gilvus mainly distinguished by the golden orange pilei, shorter pseudorrhiza, larger basidia and pleurocystidia. Termitomyces bulborhizus possess sub-globulose base at the end of the stipe similar to T. bulborhizus [45,46]. However, the bulbous stipe of type specimen BORH/FUMS-A03 tend to be smaller in size than the T. bulborhizus (Table 2).…”

New Species of Termitomyces (Lyophyllaceae, Basidiomycota) from Sabah (Northern Borneo), Malaysia

et al. 2020

View full text Add to dashboard Cite

The genus Termitomyces (Lyophyllaceae, Basidiomycota) is often associated with fungus-feeding termites (Macrotermitinae) due to their strong symbiotic relationships. The genus is widely found exclusively in certain regions of Africa and Asia. They are recognized as edible mushroom within Southeast Asia as well. But it is often misidentified based on morphology by the local communities especially in Malaysia for Chlorophyllum molybdites which is a highly poisonous mushroom. Thus, it is necessary to study the genus for Malaysia with the synergy of using both morphological and molecular identification. In this study, we aim to describe another new species as an addition to the genus Termitomyces found within Sabah, Malaysia. We generated two new sequences (nrLSU and mtSSU) for the new species and a total of 28 nrLSU and mtSSU sequences were retrieved from GenBank for the phylogenetic analysis using maximum likelihood and Bayesian inferences. We identified that the new collection from Sabah province is a new species and named as Termitomyces gilvus based on the termites found in the mound. A phylogeny tree made from the concatenated genes of LSU and mtSSU suggests that T. gilvus is closely related to T. bulborhizus from China. According to our results, the combination of molecular and morphology proved to be a robust approach to re-evaluate the taxonomic status of Termitomyces species in Malaysia. Additional surveys are needed to verify the species diversity and clarify their geographic distribution.

Termitomyces pakistanensis sp. nov. is a member of an edible genus generally distributed in Asia and Europe. This species has been described as new species based on its different morphology, and scanning electron microscopy (SEM) of basidiospores. The novelty and degree of endemism is confirmed by analyzing the genetic variation of the internal transcribed spacer regions (ITS1-5.8 S-ITS2) of the ribosomal DNA gene, a universal fungal marker. The evolutionary affinities of new species is also evaluated with Asian and European species by phylogenetic analysis based on ITS sequences. In our phylogenetic analysis, this genus is found monophyletic comprising of two monophyletic sub clades: Clade I, Microcarpus, with small sized fruiting bodies generally less than 5 cm without pseudorrhiza and Clade II, Macrocarpus, with large sized fruiting bodies generally more than 5 cm having pseudorrhiza. All collections of Pakistani species clustered independently in Microcarpus clade showing their endemic genetic makeup as it is clustering independently. A comprehensive description, photographs of the basidiocarps and Scanning electron microscopy (SEM) micrographs of spores are provided. Research Highlights • It has a new species from Pakistan to world based on the scanning electron microscopy and further confirmed by DNA barcoding.• The exact shape and size of basidiospores of this novel species is first time introduced by using SEM analysis.
