Habit, habitat, and distribution:—Solitary on loamy soil under Dalbergia sissoo or in groups on grassy grounds of the Botanical Garden of the University of Punjab. Additional materials examined:— PAKISTAN. Punjab, Chichawatni, on soil in the grounds of Chichawatni Forest, at 164 m a.s.l. under Dalbergia sissoo, 9 August 2019, Nadia Fatima, N-224, (LAH36965), GenBank ITS # ON490923. Taxonomic comments:—Within A. sect. Fulventes, Agaricus sp. (ADK2171) is the closest related species to A. radiatosquamulosus and is briefly described in Ortiz-Santana et al., (2021). It could be necessary to compare the ITS sequences, which differ at four positions, to reliably distinguish these two species from each other. In the genus Agaricus, molecular data are often required for a 100% reliable identification. Spore size comparison in Table 2 shows that this trait is not very efficient to distinguish the species of A. sect. Fulventes from each other. In addition, cap diameter can be used only to distinguish Agaricus nanofulvens, which has a much smaller cap diameter (reaching up to 2.2 cm) than the other species. In addition, it differs from A. radiatosquamulosus, by the annulus with a smooth upper surface observed in the former while striated in the later species. In addition, cheilocystidia are absent in A. nanofulvens but clavate to broadly clavate in A. radiatosquamulosus. Agaricus radiatosquamulosus is known from Punjab Province of Pakistan and likely from India according to our phylogenetic analyses. Indeed, the clade corresponding to this taxon includes five sequences of specimens from India. Unfortunately, none of these sequences retrieved from the GenBank are taxonomically documented even the only one (CBS638.89) associated with a publication (Vu et al. 2019). Several characteristics agree well with the description of A. sect. Fulventes. such as brown pileus covering, presence of annulus on upper third, annulus superous, distinct rhizomorphs at the base of stipe, Schäffer’s reaction positive but weak on stipe base in dried specimens, annulus with few inflated cells. This species is known from the Punjab Province of Pakistan and likely from India according to unpublished information found in sequence or strain repositories until now.Published as part of Bashir, Hira, Fatima, Nadia, Izhar, Aiman, Niazi, Abdul Rehman, Khalid, Abdul Nasir & Callac, Philippe, 2023, Agaricus radiatosquamulosus sp. nov. of A. subg.
