Three new records of Agaricomycetes are cited for the first time for Argentina: Cruentomycena viscidocruenta, Collybiopsis luxurians and Collybiopsis subpruinosa. Complete descriptions and illustrations are provided in this work, and color photographs of the fresh samples were added. Comments were made about the taxonomy and ecology of the species...

... R. butyracea se encuentra generalmente bajo Pinus sp. y presenta un olor diferente, fuerte y rancio (Desjardin et al., 2015). Otra especie similar pero no citada para la Argentina es Rhodocollybia prolixa (Fr.) Antonín & Noordel., aunque se diferencia principalmente por tener esporas más pequeñas, 4,5-6 × 3,2-4,4 µm ( Mata et al., 2004). Píleo (Fig. 6) 10-40 (60) mm de diám.; convexo a campanulado, un poco deprimido en el centro, y a veces un poco umbonado, luego aplanado al madurar y los márgenes se curvan hacia arriba; superficie lisa, seca; higrófano, coloración castaño ocrácea (5C6) a beige (5B4), estriado radialmente hacia el centro con tonalidades ocráceas más oscuras (5D7). ...

... Remarks.-Collybiopsis subpruinosa is characterized by relatively small basidiomes with plane-convex, rugulose striate, brown pileus, adnate to adnexed, beige lamellae, and a pubescent to tomentose stipe, with a pallid apex and greyish brown toward the base, and strigose basal mycelium; 6.4-8.2 (-9.3) × 3.9-5 (-5.4) µm basidiospores, versiform cheilocystidia, and pileocystidia often in chains of 2-3 cells (Desjardin et al., 1999;Martínez & Lechner, 2021). The Mexican collections agree well with C. subpruinosa; however, presented smaller cheilocystidia and pileocystidia than those cited (cheilocystidia 25-80 × 5-16 µm, pileocystidia 15-80 × 5-12 µm) by Desjardin et al. (1999). ...
... In the ITS phylogeny (Fig. 7), the Mexican sequence resulted in a well-supported clade (100% ML-BS, 1.00 PP, 98% MP-BS) with other samples of the same taxon from India, Madeira, and the USA. This species has a wide distribution, it has been recorded from Argentina, Brazil, Costa Rica, Ecuador, Hawaii, Jamaica, Madeira, New Zealand, Panama, Puerto Rico, and the USA, growing in hardwood litter (Desjardin et al., 1999;Song et al., 2019;Martínez & Lechner, 2021). This is the first mention of the species for the country, from Veracruz state. ...
The diversity of lignicolous agaric fungi is poorly known in Mexico. This group of fungi is responsible for the primary decomposition of wood, providing mineral elements that allow the nutrient cycles. The objective of this work was to reveal and confirm some lignicolous species present in Mexico with both morphological and molecular data. Thirteen species of eight genera, belonging to six families of lignicolous agaricoid fungi of the Agaricales were recorded, discussed, and illustrated, of which 11 are new records for Mexico. Considering our results, we confirm that Mexico is a Nearctic and Neotropical convergence zone of fungal taxa from both regions.
... Notes: Species new to Poland. It is known from Europe (Austria, Czech Republic, Denmark, France, Germany, Hungary, Italy, Netherlands, Spain, Switzerland), Africa (Benin), Asia (Pakistan, South Korea), and America (USA, Hawaiian Island, Costa Rica, Dominican Republic, Panama, Argentina, Brasil), albeit rare (Antonín & Henrik, 1999;Mata et al., 2006;Mata & Ovrebo, 2009;Antonín & Noordeloos, 2010;Lukács et al., 2010;Ludwig, 2012;Jang et al., 2015;Martínez & Lechner, 2021). It is probably a North American species, introduced and spreading worldwide (Mata et al., 2006;Antonín & Noordeloos, 2010). ...
In 2019–2020 (for 13 months), 21 macrofungi species, both native (14) and inadvertently introduced from warmer regions (7), were found in greenhouses at the Warsaw University Botanic Garden. These included 13 species recorded for the first time in Polish greenhouses. Descriptions and photographs are given for 5 species identified, which are new to Poland (Gymnopus luxurians, Hemimycena ignobilis, Leucoagaricus meleagris, L. rubrotinctus, and Xylaria arbuscula s.l.). The highest variety of species was found in the greenhouses with the collection of tropical and succulents and cacti, with 11 and 8 species, respectively. The number of species ranged from five to four in other greenhouses. The current results increase the number of species reported from greenhouses in Poland to approximately 50. None of the identified species has a negative impact on the growth and health of plants in the greenhouses at the Warsaw University Botanic Garden and at present none of them are indicated as potentially invasive.
